Room Controller (Wall Mount) Tacera 4.1 Room Controller (Wall Mount) The Room Controller links all Tacera room and corridor devices to the Austco LAN, and provides monitored and controlled power to IPnet room devices via the same cable. Figure 4‐1 Room Controller (IP‐CCT) to room cabling Power is supplied by a battery‐backed 18–28 V DC power supply, as the current consumption of 30 connected IPnet devices to a Room Controller exceeds the power rating of standard PoE switches.50 June 10, 2015 Chapter 4: Room Controller
Installation Guide Room Controller (Wall Mount) The Room Controllers are connected on the Austco LAN to the Floor Controller, which is the alarm handler, messaging and notification device integration server for a Tacera Nurse Call System. Figure 4-2 IP-CCT: Connectors and Jumpers The Room Controller and all IPnet devices are constantly monitored for current and voltage, plus each connected and registered device is “pinged” multiple times a second. The Room Controller has an internal data log of the past 40 events that can be viewed in real time from the web‐browser as a service tool for network testing. Remote diagnostics by the web‐browser is standard, and allows each device to be functionally tested remotely and its current status to be displayed in real time. Detected faults are reported immediately. The IP‐CCT board is housed in a small enclosure. The board is bolted on a galvanised steel base. A white plastic cover clips on top of it; no free space is needed around it if the cables are routed between the base and the wall or ceiling on which it is fixed.Austco June 10, 2015 51
Room Controller (Wall Mount) Tacera Figure 4‐3 IP‐CCT board & enclosure 130 mm 82 mm 190 mm 108 mm The IP‐CCT has a surface mountable metal base, PCB with connectors, and clear and concise labels indelibly printed on the board. There is a slim line plastic cover to seal against moisture and dust (as per Australian Standards), and a powder‐coated metal cover is available as an option to meet UL certification. A metal enclosure is also available for UL approval. The lid is attached to the chassis by four M3 x 6 screws, which are on the topside. Once removed, the boards and connectors are accessible. Four round (punch‐ out) holes are on the floor and bottom side of the chassis, two holes are 25 mm (0.98”), and two are 20 mm (0.79”), giving alternative methods of cable routing. For large hospital systems, a rack‐mounted hub is available with the IP‐ CCT slotted vertically in a 3U unit. See “IP‐HUB (Rack Mount)” on page 58 for more details or IP‐CCT‐SC Rack mounted 19\" for structured cabling with 16 or 32 IPnet ports. 4.1.1 IP-CCT Installation As shown in Figure 4-4, there is 20 mm (0.79”) free space between the wall and the chassis floor. This is to keep the cables out of sight. The chassis bolts on a flat surface with four M4 screws in a rectangular pattern 100 x 170 mm (3.94” x 6.69”). Room Controllers must be located in a position that is easy to access. The IP‐CCT should be labelled with the correct IP address and MAC address of the unit.52 June 10, 2015 Chapter 4: Room Controller

Room Controller (Wall Mount) Tacera 3 Remove the two end‐of‐line links in the IPnet sockets. These must be refitted to the last device connected on the IPnet cables. Connect the first IPnet cable to one of the IPnet connectors. If devices are already connected to the cable, a series of beeps will be heard as they are auto‐detected by the Room Controller. 4 Connect the second IPnet cable to the second IPnet connector. Caution Remember to distribute your device load equally between the two IPnet connectors. Using the Voltage Calculator will ensure you do not exceed the number of devices the Room Controller can power. 5 Verify that the Status LEDs are properly lit and active (Figure 4-6). 6 Replace the IP‐CCTs lid and affix the screws as needed. 7 Use the Room Controller Interface to configure the Room Controller. See the Tacera IP‐CCT Configuration Guide for details. 4.1.2 IP-CCT Status The IP‐CCT allows multiple connections and LEDs with solid or flashing lights indicate the status of some of these connections. These are detailed below. Figure 4‐6 IP‐CCT Status LEDs Ethernet Connections (A) IPnet Data (B) Power CN1 (C) Power CN2 (D) Main Power (E)54 June 10, 2015 Chapter 4: Room Controller
Installation Guide Room Controller (Wall Mount) Table 4‐2 LED Status Indication LED Indication A Yellow (SRV) ‐ Solid light means the server is connected. Green (ACT) ‐ Flashing lights means there is Ethernet activity. B Red (ERR) ‐ Solid light means there is an error. Green (SYS) ‐ Flashing light means the system is normal. Yellow (ACT) ‐ Flashing means an alarm has been triggered/cancelled. C Green (SPWR1) ‐ Solid shows that 24+V power is on to Can bus 2 D Green (SPWR2) ‐ Solid shows that 24+V power is on to Can bus 1 E Green (R40) ‐ Solid shows that 3.3+V power is applied to the board. Note Upon applying power, most LEDs will flash on and off. This is normal and indicates a reboot of the board power. Wait until the lights return to their normal states to begin diagnostics. 4.1.3 Ethernet Ethernet inputs/outputs are via two Ethernet 8‐way modular connectors compatible with any 10/100 Mbps TCP‐IP Ethernet network. These two Ethernet ports allow multiple Room Controllers to be connected in series, however, this is not recommended. Instead, directly connect each Room Controller to standard or PoE Ethernet switches. 4.1.4 IPnet Two RJ45 connectors are available to connect the Room Controller to IPnet devices. Up to 32 devices can be connected to a Room Controller using the IPnet data ports, although to allow for hot swap servicing Austco recommends a maximum of 30. Device loads should be split equally between the two connectors. Since power over the IPnet cable is supplied to all connected IPnet devices, cable lengths will be determined by the number of devices connected on the run. Caution Use the Room Controller Voltage Calculator to determine the maximum number of devices that can to be connected to a Room Controller. This ensures that IPnet devices run on sufficient power. See the Tacera IP‐ CONNECT Configuration Guide for details.Austco June 10, 2015 55
Room Controller (Wall Mount) Tacera 4.1.5 IPnet Devices IPnet devices are connected to the Room Controller using standard Cat5 or 6 cable. In and out connectors on IPnet devices allow you to connect multiple devices together in a daisy‐chain fashion. When each callpoint or device is connected on the IPnet network, the Room Controller identifies their individual device (serial number) address, assigns a DHCP‐like IPnet address and uploads all operating characteristics for the device. All details of the Room Controller are populated on a web‐browser, allowing an installer to simply group all devices for that room from a drop‐down list and save the changes, which are then uploaded to the server. As devices are connected, a short series of beeps can be heard confirming that the controller has recognized the device. As devices are powered by the IPnet cable, the back light behind the callpoint main button is also lit, providing reassurance that the callpoint is active. On the Room Controller Interface, all devices recognized by the controller are listed under IPnet Device > List. Although this auto‐ discovery functionality helps the controller “detect” devices, further configuration must be assigned to the equipment in order for devices to work properly. See the Tacera Room Controller Configuration Guides for details. The connectors at both ends of the cable are modular connectors used commonly in computer and telecommunication equipment. They are 8‐ way‐8 contacts (RJ45) and you must use 8P/8C crimp modular plugs and Ethernet over twisted pair Category 5 or 6 cable. A hand crimp tool is necessary to ensure fast and accurate terminations. 4.1.6 IP-CCT Power The Room Controller operates on a voltage between 20 and 32 V, with current consumption of 105 mA at nominal operating voltage of 24 V without any IPnet devices. The Room Controller supplies a maximum current of 1.5 A to the IPnet bus. Automatic current limiting protects the Room Controller against fault conditions on the cables going out to the callpoints and to the Over Door Lights. Fused +24 V is distributed to each callpoint on pins 4 and 5 of the IPnet cable. The Room Controller’s electronics are protected against power surges, near‐lightning strikes, cable shorts and power reversals. 4.1.7 IP-CCT Configuration Some site configuration such as call types, Over Door Light colour, blinking schemes and audio notification tones, can be specified for all controllers on‐site or for individual controllers. 56 June 10, 2015 Chapter 4: Room Controller
Installation Guide Room Controller (Wall Mount) The operation of each room’s Over Door Light can be individually programmed or operate from a global template. The Over Door Light colours and flashing rates for each callpoint priority are selectable via the web‐browser application. This includes multiple colour segments for selectable call priorities. Devices are specific to each controller and as such must be configured individually. Please refer to the Tacera IP‐CCT Configuration Guides for details on the configuration of the Room Controller. The Room Controller firmware and callpoint configuration files can be upgraded in real time without shutting down the system. This allows changes to be made on a working system without interruption to the operation of the system. When a Room Controller is powered up with J1 opened, it resets the board configuration back to factory default. All configuration data is wiped with a default IP address 10.1.1.1/ 255.255.255.0 (is important to include the net mask). To connect to it after the reset, you must set the PC to 10.1.1.x. Jump back J1 or else every time the board loses power it will reset itself to default.Austco June 10, 2015 57
IP-HUB (Rack Mount) Tacera 4.2 IP-HUB (Rack Mount) The IP‐HUB is comprised of: • The Hub chassis • The Controller boards (IP‐CCT/H) Figure 4‐7 The IP‐HUB The IP‐HUB allows up to 10 IP‐CCT/H boards to be slotted into it, each exposing the four ports (two Ethernet, two IPnet) and the power connector. This means that one rack can support up to 300 devices. These are subject to voltage drops and cable run lengths. Multiple racks can be used if needed. A Floor Controller can easily support four IP‐HUBs. When ordering the IP‐HUB, indicate the number of IP‐CCT/H boards required. 4.2.1 IP-HUB Installation The IP‐HUB is designed to fit into a 19\" rack and occupies 3U space, with a depth of 160 mm (6.3”). 1 When new boards are needed, unscrew one of the blank panels, and insert the new IP‐CCT/H board. 2 Reinsert the screws provided with the blank panel. 3 Connect the IP‐CCT/H controller as usual. 4.2.2 IP-HUB Configuration The configuration of the IP‐CCT/H controller is the same as the IP‐CCT. See “IP‐CCT Configuration” on page 56.58 June 10, 2015 Chapter 4: Room Controller
Installation Guide IP-CCT-SC (Structured Cabling) 4.3 IP-CCT-SC (Structured Cabling) The IP‐CCT‐SC has 16 or 32 ports (depending on the model) which allows up to 16 or 32 devices in a structured cabling system. These are subject to voltage drops and cable run lengths (up to 100 m). See “Structured cabling with IP‐CCT‐SC” on page 43. Figure 4‐8 IP‐CCT‐SC When ordering the IP‐CCT‐SC, indicate the number of devices required: • Single Room Controller (IP‐CCT) with 16 IPnet ports (IP‐CCT‐SC/ 1x16) • Dual Room Controller (IP‐CCT) with 16 IPnet ports for each Room Controller (IP‐CCT‐SC/2x16). The maximum number of IPnet devices per port is five. The IP‐CCT‐SC is short circuit protected with automatic recovery. 4.3.1 IP-CCT-SC Installation The IP‐CCT‐SC is designed to fit into a 19\" rack and occupies 1U space with a depth of 285 mm (11.22”). The enclosure can hold either 1 or 2 Ethernet controller cards, which are quick and easy to commission. 4.3.2 IP-CCT-SC Configuration The configuration of the IP‐CCT‐SC is the same as the IP‐CCT.

PATIENT STATION 5 The Tacera Patient Station (IP‐PST) is a wall or bedhead unit that provides a complete in‐room patient call and audio solution. A single bedroom can have one Patient Station and a multi‐bedroom can have one Patient Station per bed. The device serves as an IPnet Room Controller supporting all current IPnet device types. The Patient Station can be used in place of a Room Controller (IP‐CCT). The Patient Station is also compatible with digital pendants, including the Entertainment Multifunction Handset (IP‐EMH) which offers a sophisticated television patient entertainment system interface along with up to four nurse assist buttons and up to four environment buttons for lights, fans, blinds or air conditioners. Table 5‐1 Tacera Patient Station Product Code Description IP‐PST VoIP Patient StationAustco June 10, 2015 61
Device Description Tacera Active 5.1 Device Description VoIP LED Three on‐board call buttons and cancel button allow nurse calls like staff presence, staff assist, or code blue, to be directly supported on the unit thereby saving on additional callpoints. The set of call types offered on these buttons can be changed. On‐board full‐duplex audio allows staff to be in contact with the patient and using VoIP SIP allows for simple connectivity. A full range of Austco pendants, handset, multifunction handsets and auxiliary input can be directly connected to the unit. Over Bed Light, and flexible dual relay are directly connected. The call buttons feature soft touch operation and are manufactured with anti‐bacterial additive as an infection control measure. Backlighting of the call buttons provides for easy location and operation at night. Audible and visual reassurance is by a pressed button tone sounder and reassurance LED behind the cancel button buzzer is standard. Pendant removal, either accidental or intentional generates a pendant unplug alarm. ‘Cleaning mode’ prevents accidental activation while disinfecting the fascia and provides a history log of all cleaned devices within the room.

Installation Guide Customising the Patient Station 5.4 Customising the Patient Station The Patient Station comes with a variety of button inserts and optional USB/pendant socket covers. A default configuration is applied to the station, however it is possible to define your own configuration. • The Patient Station comes with the default Cancel button and three other call buttons that you chose when placing an order. To remove a button, simply lift it up. The replaceable caps ensure each button’s function is clearly identified. • If you want to swap or change buttons, remove and insert the buttons at required locations. Note You cannot change the position of the cancel callpoint, however, you can choose from a few different callpoint buttons available for the call type. • If you don’t want the USB interface or pendant sockets, you can hide them using appropriate covers that you can order and have them shipped with the product. The Patient Station is web configurable and supports remote software upgrade. For further details on customisation and configuration, see the Tacera IP‐PST Configuration Guide. When any call is active on the Patient Station (either from button or from pendant) then the cancel button is illuminated. The callpoint button acts as an IPnet device with one device per button. The call buttons can be assigned any call type like a regular CPG callpoint. The upgrades: hold 3 seconds (3HU) and three press (3PU) are supported. The call buttons are backlit for night visibility and when a call is active they illuminate. IP‐PSTs are delivered without buttons. All buttons including Cancel are ordered separately from the IP‐PST. If button is not used, then fit one of the generic buttons. There is no plastic filler provided.

Depending on the smart TV, set top box or media server, IP‐PST will need to implement the specific control protocol to change channels, volume and menu functions. With a project requiring Ethernet control, please contact Austco support to determine if this protocol can be supported. The audio still needs to be connected to AM‐TVUSB. A RJ11 to stereo jack or RCA cable needs to be made. The IP‐PST must be configured if volume control is required by IP‐EMH. The AM‐TVUSB must have its jumpers set for as follows: Table 5‐12 AM‐TVUSB Jumper settings for Ethernet TV Control Jumper Detail Ethernet Control Mode 1 TV Control Collector 12 V Pull‐up 2 TV Control Collector ground 3 TV Control Collector to RJ11 pin4 4 TV Control Emitter to ground 5 TV Control Emitter to RJ11 pin4 6 12 V to RJ11 pin1 7 TV Audio bypass capacitors Fitted 8 Ground to TV Common Vodoke Handset Austco are working with Vodoke on a pendant that will work with the Vodoke playSTAQ. The Vodoke handset offers a wireless TV control including air mouse support. Audio is either at TV or can be via headset plugged into Vodoke cable. Audio to the headset is also wireless. Vodoke handset does not support intercom. Vodoke handset has backlit nurse call button as well as drink and toilet nurse assist buttons and 2 light environment buttons. Vodoke handset comes with DIN8 with inbuilt headset 3.5 mm jack. The AM‐TVUSB need not be used. To directly connect the Vodoke handset to the IP‐PST a DIN8 to USB breakaway cable is required, similar to the one used for IP‐EMH. Ethernet PoE+ (IEEE 802.3at) RJ45 shielded connector is provided for Ethernet connections. To support PoE+ all 8‐pins of the connector are used. It is recommended that at least a 100 Mbps Network switch is used. IP‐PST does not operate at GbE and will operate at 100 Mbps. June 10, 2015 83
Network Cabling Tacera Network connection Green LED and data activity yellow LED are supported to aid diagnosis of network issues. Note IEEE 802.3af (regular PoE) is not compatible and will not power IP‐PST. When 24 V is used, the Network Switch must be standard Ethernet type and not PoE type. 5.5.4 IP-PST IPnet The Patient Station supports up to 10 IPnet devices across CN1 and CN2 (ISO‐8877 8p8C RJ45 sockets). RJ45 non‐shielded connectors are provided for IPnet. All 8‐pins of the connector are used. The second IPnet data bus can be used as an alternate intercommunication between IP‐PSTs should Ethernet fail. Contact Austco for further details on what is required to interconnect Patient Stations using the 2nd data channel. If the IPnet connector is not used, then a terminator must be fitted to ensure reliable operation of the IPnet bus. The IPnet interface provides a soft start circuit to limit in rush current to avoid over‐current shut‐down of PoE+. The IPnet interface provides short circuit protection to ensure power supply is not damaged.84 June 10, 2015 Chapter 5: Patient Station

Network Cabling Tacera 5.5.5 IP-PST Auxiliary Interface The Patient Station supports two auxiliary alarm interfaces by means of pendant sockets at the left and right side of the unit. The IP‐PST supports the following types of devices for the auxiliary alarm interface: • pendant with patient call (CM‐PCP, CM‐SCP, CM‐P/U, CS‐PMPAD) • bed mat, with open circuit as alarm state • floor mat, with short circuit as alarm state • auxiliary medical device with contact closure. Figure 5‐14 IP‐PST pendant socket connections For information about how to set up the auxiliary interface call types, refer to the Tacera IP‐PST Configuration Guide. The call button can also be assigned as an enable for the pendant mat operation. When used as an enable point it no longer functions as a callpoint and it will not appear in IPnet device list. 6.35 mm Pendants The pendant interface supports the following: • TIP ‐ Pendant Call • RING ‐ 2 light controls or 2 additional calls • SLEEVE ‐ Ground. Pendant unplug is supported. The configuration of the interface defines if the TIP is NO (Normally Open) or NC (Normally Closed) activated and the delay assigned before the alarm is activated. A normally closed impedance of up to 300 Ohm is supported. 86 June 10, 2015 Chapter 5: Patient Station
Installation Guide Network Cabling Digital Pendants The Patient Station supports a single digital pendant interface located under the lower right hand side button. Note The left hand side digital interface is not fitted to the IP‐PST. For IP‐EMH, the AM‐TVUSB must be used. The AM‐TVUSB serves to split the USB signals from the analogue TV signals contained in the IP‐EMH cable. The IP‐EMH with DIN8 breakaway is directly connected to the AM‐ TVUSB. A USB Type A cable (provided with the AM‐TVUSB) links the AM‐TVUSB (rear) to the IP‐PST. The IP‐PST Type A uses a latching type connector to avoid the USB cable from being dislodged accidentally. Caution Do not exert undue force in trying to try remove the USB cable as it will damage the IP‐PST PCB, USB connector and cable. To release the USB cable it is recommended to insert a small flat blade screwdriver into the gap between connector body and underside of tab. A gentle rotation of the flat blade screwdriver will raise the tab and allow the cable to be easily removed. Caution Only use USB cables provided by Austco and do not add USB extension cables as the IP‐EMH handset may not operate on substandard cables or extension cables. Digital pendant offer many additional features over analogue pendants including: • Up to 4 nurse assist call buttons. For example: Drink, Toilet, Pain, Cleaning. • TV controls: • On/off • Channel up/down • Channel digits • Volume up/down/mute • Menu controls, left/right/up/down, enter/return. • Torch • Up to 4 environmental controls. For example, room and reading lights, fan speed, blinds, air conditioning. • TV audio • Full duplex intercom. Note No all‐digital pendants offer all of these features. Note The ancillary module AM‐TVUSB is required for TV integrations requiring analogue TV sound.Austco June 10, 2015 87
Network Cabling Tacera SIP Audio The Patient Station supports SIP based full duplex VoIP telephony. Patient Stations are configured to auto‐answer any incoming calls. A green LED is illuminated indicating an audio session is in progress. Note The calling party must hang‐up to end the call. Installers should consider adding a time‐out to automatically clear the call to avoid any stuck audio calls should the calling party fail. Announcement Tone Installers need to configure dial plans so that a short beep or similar tone is played before any speech. This ensures the patient is not startled when staff starts speaking to them. Pendant Intercom Digital pendants such as IP‐EMH support intercom direct to the handset. When a patient call is raised on the pendant then the click‐to‐call from the staff can be assigned to call the handset and not the patient station. Mute of Pendant TV Sound The Patient Station will mute the TV audio on the digital pendant should the intercom audio be active. SIP Registration The Patient Station is set up for connection to the Asterisk PBX provided with the IP‐ACS‐110. Use of alternative soft switches to Asterisk have not been verified. The extension numbers for the Patient Station on‐board audio and the extension number of the digital handset (if used) can be defined. Volume Control The speaker and microphone levels can be adjusted from the Room Controller Interface. See Tacera IP‐PST Configuration Guide. TV Integration The Patient Station with digital handset IP‐EMH offers many ways to integrate with TV.88 June 10, 2015 Chapter 5: Patient Station

IPNET DEVICES 6 Austco’s new generation of IPnet devices comprise a nurse call system using IP technology and auto‐discovery features making installation, configuration, and commissioning of an Austco system now easier than ever.Austco June 10, 2015 91
IPnet Basics Tacera92 6.1 IPnet Basics IPnet devices are connected to the Room Controller (IP‐CCT or IP‐PST) via the two RJ45 connectors provided. There is no specific in and out connector. The system interfaces to the Room Controller via a Cat5 or Cat6 UTP cable with 8‐way modular connectors. Two IPnet ports allow both power and IPnet data to pass through the device on one IPnet run. See the Chapter “Best Practice” for information on setting up a system. Up to 32 IPnet devices can be connected per IP‐CCT, although to allow for hot swap servicing Austco recommends a maximum of 30, subject to power loading and a maximum cable length of 300 m. Devices should be distributed evenly between the two IPnet ports to balance the power load. See “Cabling Requirements” on page 34. Callpoints are auto‐discovered with their own unique device address. When connected to the IPnet, an IPnet address is automatically assigned. Access via a web‐browser allows all callpoints to be configured and assigned to areas for Over Door Light operation and Annunciator display of alarms. All visible IPnet devices should be mounted either vertically or horizontally at the height and location specified in the customer specification document. After installation, the IPnet device will have a surround plate fitted to cover the screw mounting. 6.1.1 Power The IPnet devices do not require a separate power feed. Here is how each of the IPnet devices is powered: • The IPnet devices operate in the range 12–28 V DC. See “Appendix: Power Rating” on page 247. • The callpoints and tone sounders are powered over the IPnet cable. Typical power consumption is 20 mA at 24 V when a call is active and 5 mA when on standby. • The Over Door Lights are powered over the IPnet cable. Each one takes 25 mA when the LED of the corresponding alarm is on. The LEDs are protected against a cable reversal. Typical power consumption is 15 mA at 24 V per colour when lit. The unit is powered via the IPnet cable and no direct or separate power feed is required. • Relays and inputs are powered over the IPnet cable. Typical power consumption is 15 mA at 24 V DC at nominal. • The IP‐TJ is powered over the IPnet cable and does not require a separate power feed. Typical power consumption is 24 V. IP‐ODL‐4RGB has the option for additional power to be injected through the CN3 port (See Figure 6-22 for more details) to increase input voltage. Additional power must be provided from the same power supply that powers the Room Controller supporting the Over Door Light. The IPnet device electronics are protected against power surges, near lightning strikes, cable shorts and power reversals. June 10, 2015 Chapter 6: IPnet Devices
Installation Guide IPnet Basics The active call indication is available as an output for connection to an external over bed indicator light or elapsed timer input. Over Bed Light connection terminals with +12 V power are provided although voltage drop to lights must be factored in the overall powering of the cable run. 6.1.2 Safety Earth If there is a requirement for all exposed metal parts to be connected to a safety earth, then it will be necessary to earth the metal trim for the entertainment handset DIN connector. The rear of the connector has a solder tab onto which an earth lead can be soldered. 6.1.3 Configuration Most of the IPnet devices are pre‐configured with their type at the factory. As they are connected on the line to the Room Controller, the devices are auto‐detected, assigned an IPnet address, and callpoint features such as pendant sockets are pre‐defined for easier configuration. The operating parameters of each Over Door Light, including priority, function, and location, can be upgraded in real time without shutting down the system. This allows changes to be made on a working system without interruption to the operating of the system. Here are some of the IPnet device properties that can be customized using the Room Controller Interface (web‐based configuration tool): • assign the callpoints to a zone (e.g. room) and change the default call type for fixed‐button callpoints, assign pendant removal alarms, define call guarding and upgrades • assign call types for generic callpoints, which are not pre‐ configured at the factory • configure the Cancel call type as a source (S) in cancel groups of other call types. With cancel groups, you can cancel more than one configured call type at one button press. • assign the Over Door Light to a zone. For each call priority, the colour of each segment, the number of segments and flashing rates are set in the Room Controller Interface as either a specific standard for that Room Controller or as a global standard for the site. • assign the tones sounders to a zone and define which audio scheme they follow from the Tone section. A regional scheme can be selected and modified as needed. • Over Door Lights and tone sounders can be configured to form a navigation pathway for staff to quickly direct them to the source of the call. This feature is called Follow‐Me Lighting for the Over Door Lights and Distributed ZTS for the tone sounders.Austco June 10, 2015 93
IPnet Basics Tacera • create a Cancel Link between specific callpoints, in which pressing the CANCEL button on the source callpoint cancels the call of the destination callpoint. For example, a cancel link can be formed with the Patient Call callpoint as the source and a Pull Cord callpoint as the destination. When a call is triggered from the Pull Cord callpoint (destination), the red CANCEL button on the Patient Call callpoint (source) will illuminate, pressing the Patient Call CANCEL button will cancel the call from the linked Pull Cord callpoint. • for the input devices (IP‐IN8 and IP‐OPT8), define the type and priority level to be independently programmed for each call input (bed, emergency, fire, security, etc.). For more details on configuration or using the Room Controller Interface, see the Tacera Room Controller Configuration Guides.94 June 10, 2015 Chapter 6: IPnet Devices

All these callpoints have a common construction, cleaning, installation procedures, buzzer and backlight setup, call options and configuration. The generic (replaceable button) callpoints and fixed button callpoints have the same call activation and cancellation procedures, whereas these procedures differ for the other callpoint types. The IP‐CPS series is a set of fixed‐button callpoints. Figure 6‐1 The IP‐CPS Callpoint Front and BackAustco June 10, 2015 95
Callpoints Overview Tacera Each callpoint consists of a: • soft touch 40 x 25 mm (1.57 x 0.98”) maximum diameter oval tactile snap‐action silicone CALL button, in selectable colours and icon labels • 15 mm (0.59”) grey oval button labelled CANCEL in 3.5 mm (0.14”) letters. Generic callpoints are intended to replace the regular fixed‐button callpoints. Having a replacement button label means you can order a common callpoint and apply the label once the type is decided upon. The IP‐CPG is a generic callpoint which offers the flexibility for callpoint buttons to be assigned during installation. Button labels can be changed as required even after the callpoint has been installed. Figure 6‐2 The IP‐CPG Callpoint Front and Back Each callpoint consists of a: • 35 x 20 mm (1.38” x 0.79”) diameter oval tactile snap‐action button, in selectable colours and icon labels, surrounded in a 5 mm (0.2”) fitting • 15 mm (0.59”) grey oval button labelled C in 3.5 mm (0.14”) letters. Button labels are provided as icon button inserts, available in all standard call types. AM‐CPG button inserts snap into the silicone button fitting of the plate. 6.2.1 Construction The main Call and small Cancel buttons are manufactured from silicone rubber with an anti‐bacterial additive. The mounting plate is manufactured from a white polycarbonate/ABS blend of impact‐resistant plastic with a snap‐on surround to conceal the fixings (the surround is supplied separately). Each callpoint includes a unique barcode for inventory control and tracking.96 June 10, 2015 Chapter 6: IPnet Devices
Installation Guide Callpoints Overview The main button contacts are gold plated with a mechanical snap action for long life at low current levels. There are four separate contact elements equidistant from the centre of the button to ensure reliability. The operating parameters of each callpoint, including priority, function and location, can be upgraded in real time without shutting down the system. This allows changes to be made on a working system without interruption to the operation of the system. All callpoints fit into a standard single‐ or multi‐gang Australian and North American wall box. They use a standard Clipsal 2000 series snap‐ on surround that must be ordered separately. The ‘/BS’ option fits into standard British size wall boxes and comes without surrounds in a single unit with plastic plugs used to cover exposed screws. 6.2.2 Button Inserts The AM‐CPG icon button inserts are for the generic callpoints and can be removed from its silicone fitting on the front plate using a small tool, like a flat‐tip screwdriver. Another button insert can be fitted into the empty silicone fitting as a replacement. Callpoint buttons can be easily changed to reflect the latest configured call type for that callpoint. Figure 6‐3 Sample button inserts 6.2.3 Installation Figure 6-4 is a sketch depicting the common construction of all CPS (Callpoint Silicone) callpoints and IP‐ZTS (Tone Sounders). Two sizes of grid plates are available, to fit different wall boxes: • “Australian Plate” on page 98 • “British Plate” on page 100.Austco June 10, 2015 97
Callpoints Overview Tacera Callpoints accept the same silicone push‐button pads. There is a choice of colours and markings, which is specified within the order code. The callpoint is supplied on a vertical plate by default, horizontal if the option ‘/H’ is added to the code. The silicone pads differ, being printed across the small axis of the buttons for the horizontal version. Figure 6‐4 Components of a CPS callpoint Silicone Pad Board Assembly Wall Box Grid Plate Call Button 84 Cancel Button The electronics boards at the back are the same for all callpoints, they always carry the connectors, a small buzzer, a white LED behind the large call button to back light it in the dark, and a reassurance LED behind the Cancel button. A pendant connector is optional on most models. Water‐proofing is required for wet areas. See “Waterproof” on page 104. Australian Plate Note The USA and Canada callpoint grid‐plate is the same as the Australian version. The CPS callpoints are shipped on this type of plate by default (if the British size is not specified). It fits standard Australian and North American wall boxes, and is the one shown in the two previous figures. It is compatible with the Clipsal 2000 series of electrical switches and accessories. Two mounting screws M 3.5 x 0.8 x 32 mm (approx. 6–32 UNC) are supplied with each callpoint. The grid plate is 111 x 68 mm (4.37 x 2.68”), with a standard mounting pattern (84 mm (3.3”) centres). The flush surround (116 x 76 mm/4.57” x 2.99”) clips on top after decorating has been completed. Depth behind the wall surface (inside the wall box) is 22 mm (0.87”), however at least 35 mm (1.38”) is required for cable termination (45 mm/1.77”) if cables have moulded strain relief boots). The surface of the callpoint is 12 mm (0.47”) in front of the wall.98 June 10, 2015 Chapter 6: IPnet Devices
