Overview

The Tek-CARE160 system is a versatile system that can satisfy the needs of a wide range

of facilities. At its core, the Tek-CARE160 system is a four-wire nurse call system

designed for easy installation and years of trouble-free operation. The system is available

with a variety of call stations such as two-button pull-cord stations, 1/4" jack call cord sta-

tions, duty stations, dome lights, and more.

In addition to these items, the Tek-CARE160 system can be easily integrated with exist-

ing TekTone nurse call systems, nurse call systems manufactured by other companies, as

well as a wide variety of building systems such as fire alarm systems, security and access

control systems, and much more.

The Tek-CARE160 system may be used as either a standalone nurse call system using

NC415AV/NC404TS Master Stations, or it may be connected to another TekTone nurse

call system, such as the Tek-CARE400 or Tek-CARE400P5/Tek-CARE400P5+ over the

Tek-CARE Network. With the addition of the LS601 Tek-ALERT Integration Manager,

the Tek-CARE160 system is capable of communicating with many other types of building

systems, such as fire alarm and security systems. The LS601 Tek-ALERT Integration Man-

ager also allows the system to display and log various events from older analog TekTone

nurse call systems such as the Tek-CARE NC110, NC150, NC200, and 300/III systems.

Product Overview

NC160 Central Equipment Module: The Tek-CARE160 sys-

tem's main component is the NC160 Central Equipment (CE) Mod-

ule. The CE module is designed to be stackable or rack mountable.

The NC160 CE Module can operate as a standalone system, or as

a module on a larger, integrated Tek-CARE nurse call system. The

NC160 CE Module provides connections for 64 room controllers,

and six NC415AV or ten NC404TS Master Stations. Multiple CE

modules may be networked together to create a larger system.

NC415AV Master Station: The NC415AV Master Station is a

touchscreen master station that is used to interact with the Tek-

CARE160 system. The NC415AV Master Station displays calls

from the Tek-CARE160 system and provides limited pro-

gramming and configuration ability for the Tek-CARE160 system.

The NC415AV uses a five-inch LCD touchscreen to provide aud-

ible and visual annunciation of system calls. The NC415AV may

be mounted using the IH415D desk stand or wall-mounted using

the IH415W wall-mount bracket.

NC404TS Master Station: The NC404TS Master Station is a

touchscreen master station that is used to interact with the Tek-

CARE160 system. The NC404TS Master Station can display

maps and calls from the Tek-CARE160 system and provides pro-

gramming and configuration ability for the Tek-CARE160 system.

The NC404TS uses a 22-inch LCD touchscreen to provide audible

and visual annunciation of system calls. The NC404TS may be

mounted using the CL231 bracket.

LI122/LI122BL Room Controller: The LI122-Series Room

Controller provides connections for six Tek-CARE160 stations

and one connection for the Tek-CARE160 data bus. In most

instances, the room controller is installed outside a room in the

same position as a traditional dome light. The two-conductor cable

is used to connect Tek-CARE160 stations to the LI122-Series

Room Controllers. The rear of the room controller contains a 14-

pin header. Pins 1-12 are used in pairs for station connections, and

pins 13 and 14 are used to connect the room controller to the Tek-

CARE160 data bus. The LI122 annunciates high priority calls

with red LEDs and low priority calls with white LEDs. The

LI122BL is identical to the LI122, but with blue LEDs for high pri-

ority calls and white LEDs for low priority calls.

PM120 Room Controller: The PM120 Room Controller

provides connection points for Tek-CARE160 stations without the

dome light LEDs found on the LI122-series room controllers. The

PM120 is designed to be installed out of sight.

Introduction and Overview

IR160 Audio Station: The IR160 Audio Station provides a

speaker and microphone for two-way communication between

facility staff and residents. The IR160 requires a connection to the

LI122 controller (using one point) and a connection to the Tek-

CARE160 Audio Bus cable. The IR160 Audio Station can be

installed as a standalone speaker, but is most commonly installed

with an SF121 or an SF123 series station in an IH122K dual

house gang housing. The IR160 shown to the left is shown with a

SF121 Patient Station.

SF121 and SF122 Patient Stations: The SF121 Patient Station

is designed to provide a single 1/4" jack for standard call cords.

The SF121 mounts near a resident’s bed or chair, and enables calls

to be placed using pushbutton call cords, geriatric call cords, pneu-

matic call cords, and more. The SF121 is equipped with an illu-

minated reset button. The SF122 Patient Station is a dual-jack

version of the SF121.

SF123 2-Button Pull-Cord Station: The SF123 station is used

to place a variety of calls on the Tek-CARE160 system. The

SF123 uses interchangeable inserts depending on the desired func-

tion of the station. The SF123 is most commonly used as an Emer-

gency station, but can be easily configured for Bath, Code Blue,

and Emergency 2 calls. Custom call types may also be created, and

custom call type inserts can be generated using the LS450 Config

Tool software. The SF123 can also be used as a room-level reset

button and a check-in station. Use the RP187K Gasket Kit for

mounting in wet environments.

SF125 Duty Station: The SF125 is a duty station used to alert

staff to pending Tek-CARE160 system calls. The duty station is

installed in areas where call annunciation is needed, but the full

functionality of a master station is not. Four LEDs communicate

the type of active call, and an audible tone alerts staff members

when calls are placed. The SF125 duty station uses two points on

the LI122-series Room Controller or PM120 Room Controller.

PM123 Auxiliary Input Module: The PM123 is a module used

to monitor normally open dry contacts such as door switches,

emergency pushbuttons, and alarm contact outputs. The PM123 is

designed to be installed out of sight. Up to two individual contacts

can be monitored with a single PM123. The PM123 may also be

used as an auxiliary check-in device. Normally open contacts such

as door switches, motion detectors, or pressure pads may be used

with the PM123 to satisfy a resident check-in requirement on the

system.

Installation

Installation for the Tek-CARE160 system is designed to be very straightforward. The audio bus is

designed to operate on unshielded 18/2 AWG twisted cable.

When making wiring connections, use quality crimp connectors such as Dolphin®Super B®connectors.

Do not use wire nuts. Adequately protect all splices using junction boxes.

Installation Workflow:

oInstall all NC160 CEModules.

oInstall the backup batteries.

oRun data and audio bus wiring through the facility.

oInstall and address LI122-Series/PM120 Room Controllers.

oConnect the audio bus to IR160 stations.

oRun master bus wiring and make 8P8C terminations.

oCheck data bus for shorts and connect master and data bus wiring to the NC160 CEModule.

oPower on the NC160 CEModule.

oCreate a configuration using the LS450 Config Tool software.

oTest the Tek-CARE160 system.

oBack up the configuration and turn the system over to the facility.

Types of Installation

There are two types of installations available for the Tek-CARE160 system, a One-to-One installation and a

Custom installation.

One-to-One

A one-to-one installation strategy involves installing a single LI122-series Room Controller outside of

each room in the facility and using the points on that room controller to connect to stations installed in

that room.

In this installation strategy, stations are normally wired to their default points on the room controller.

The room controller will then annunciate calls from its attached stations only.

Custom

In a custom installation, each point on a room controller can be reassigned to a unique Station ID. This

enables the room controller to drive stations installed in different rooms. A custom installation strategy

also enables a single room controller to drive multiple patient stations in a single area, such as a ward.

Note: Custom installations require training and a Config Tool Plus or Config Tool Elite

license.

Installation

Installation Concerns

When installing the Tek-CARE160 system, organization is key. As you install the system, note the DIP

switch address of each room controller, the physical location of the room controller, and which stations

are connected to the room controller on each point.

Keeping detailed records throughout the installation process will greatly simplify system programming

and setup. A programming worksheet is included at the end of this manual.

Below is an example of a completed programming worksheet.

Power Considerations

In order to stay within the power limits of the NC160 CEModule and ensure reliable system per-

formance, the Tek-CARE160 Power Calculator may be downloaded at:

http://www.tektone.com/pdf_files/gen2_master_station_load_value_calculator.xlsx

Figure 1 - NC160 CEModuleConnections

Installation

The NC160 Central Equipment Module

The NC160 Central Equipment Module contains all the necessary connections for the Tek-CARE160

hardware as well as the backup batteries for the system. The NC160 CEModule is designed to be moun-

ted in a standard 19" server rack using included CL120RM brackets. Modules may also be desk-mounted

and stacked. The NC160 CEModule requires 160VAC or 240VAC power, and must be connected to a

generator-backed circuit intended for life safety equipment.

If the NC160 CEModule is not mounted in a server rack, allow adequate air space around the front,

sides, and back of the unit. At least 6" of airspace must be maintained for the unit to operate reliably.

Refer to Figure 1 on page 9 for NC160 CE port descriptions.

On the front of the NC160 CEModule, you will find a bank of DIP switches. These DIP switches are

used to configure various options on the CE module and to provide an address for the CE module.

Figure 2 - Module Dip Switch Addressing

The small bank of 4 DIP switches on the left is used for the following functions. Note that the down pos-

ition of the switch is on. Normal settings are indicated in parenthesis.

Switch 1 – Redefault the database. (Off/Up)

Switch 2 – Silence the audio alarm buzzer. (On/Down)

Switch 3 – Redefault network subnet assignment to 192.168.1. (Off/Up)

Switch 4 – Factory and troubleshooting use only. (Off/Up)

The second bank of 8 DIP switches is used to set the address of the NC160 CEModule.

Switch 1 – Switch 7 – Used to select the CE module’s address. Valid addresses are 1-75. Note that

though there are 75 available DIP switch addresses, no more than 20 modules may be installed on a

single Tek-CARE system. Switch 1- Switch 7 utilize standard binary addressing, with Switch 1 being 1

and Switch 7 being 64.

Switch 8 – Factory Use Only. (leave turned Off/Up)

Install Backup Batteries

Before proceeding with system setup, install the backup batteries in the module. Open the two battery

compartment covers on the top of the module.

Locate the red (positive) and black (negative) wires with female spade connectors under each door.

Move the wires out of the way and place the batteries in the holders and connect the spade terminals to

the batteries as shown below.

Connect the red leads to the positive terminal of each battery and the black leads to the negative ter-

minal of each battery.

Figure 3 - Battery Connections

The Tek-CARE160 Data Bus

The Tek-CARE160 data bus is a two-wire serial communications bus. There are four ports on the front of

the module, each capable of driving up to 1,000 feet of data bus and up to 16 LI122-Series or room con-

trollers.

There are four 8P8C jacks on the front of the module. The two on the right are for NC415AV/NC404TS

Master Stations, and two on the left for Tek-CARE Network connectivity. Each module supports up to

six master stations, three per port.

To begin installing the NC160 CEModule, mount the module either on a server rack or on a shelf. Plug

in the supplied AC power cord, and turn the unit on. You are now ready to begin connecting field wir-

ing to the module.

Installation

Tek-CARE160 Installation Considerations

Note that the audio bus on the Tek-CARE160 system is analog, and thus, only supports one concurrent

audio connection per port.

For example, if a facility has IR160 stations in rooms 100-110 connected to Port 0 and rooms 111-160

connected to port 1, one NC415AV/NC404TS Master Station could connect audio to Room 100 and

another NC415AV/NC404TS Master Station could connect audio to room 111. If amaster station

attempts to connect to an audio bus that is already in use, the connection will fail.

When installing cabling, be sure to keep the audio bus and the data bus for each port together. Remem-

ber that the IR160 requires a connection to the room controller and the audio bus. If the IR160 is con-

nected to a room controller that uses Data Bus Port 0, but the audio bus for that IR160 connects to Port

1, the audio connection will not function.

Installation

Audio Connection Considerations

The most common scenario for installing the Tek-CARE system is to have a single IR160 Audio Station

associated with a single room controller, and thus, a single Station ID.

Up to four IR160 Audio Stations may be associated with a single Station ID, however, all IR160s asso-

ciated with a station ID will open their audio connections simultaneously.

Example 1

In the example shown in Figure 5 on page 13, a single LI122 room controller is installed outside of the

room. An SF122 is connected to Point 1, an SF123 is connected to Point 4 (creating a Bath call) and an

IR160 is connected to Point 6. Note that the audio cable never connects to the room controller.

In this example, all three stations are associated with a single Station ID, meaning that any call from this

station ID (SF122 or SF123) is answered at the master station, the audio channel opens.

Example 2

The example shown in Figure 6 on page 15 illustrates a slightly different wiring scheme utilizing the

same room layout. In this example, everything is the same as before except there is an additional IR160

installed in the bathroom. Again, in this scenario, all four stations are connected to a single room con-

troller, and associated with a single station ID.

In this scenario, a call from either the SF122 Patient Station or the SF123 Bath Station will open audio

to both IR160 stations. This scenario requires that the system be manually configured to expect an

IR160 connected to point 5.

Example 3

If unique audio in each location is desired, a Plus or Elite license is required for the LS450 Config Tool

Software. This enables the points of one controller to be assigned to different station IDs.

Returning to Figure 6 on page 15, if the facility requires unique audio connections at both the bed and

the bath areas, simply assign Points 1 and 6 of the room controller to a Station ID (e.g. RM 100) and the

other two points to a different station ID (e.g. 100 BATH).

Once the points have been reassigned, answering calls or dialing each station ID will only open audio at

the IR160 that is associated with that station ID.

Wiring Installation

Tek-CARE160 Data Bus Wiring

The main wiring for the Tek-CARE160 system consists of a two wire communications data bus. The

data bus ports on the front of the NC160 CEModule are capable of supporting 16 room controllers each,

for a total of 64 controllers per module. Note that each port is capable of driving up to 1,000' of cable

for the data bus. TekTone recommends 18/2 stranded cable for the data bus, but other types of wiring are

acceptable. See the table below for details.

Note: If 22 AWG cable is used, the data bus runs can be extended by twisting conductors

together at each splice. For example, 22/4 cable used for data bus wiring could have two

conductors twisted together for the positive leg of the data bus and two conductors twis-

ted together for the negative leg.

Figure 6 - Typical Room with two IR160 Audio Stations

Installation

Run wiring from room controller to room controller and connect the room controllers to the data bus in

parallel using T-taps. Connect the positive wire in the data bus cable to the solid white wire (pin 13) on

the back of the room controller, and connect the negative wire from the data bus to the black wire (pin

14) on the room controller.

Note: CAT5 cable is not recommended for use on the data bus of the Tek-CARE160 due to brittle con-

ductors and difficulty in creating reliable crimp connections to larger gauge wire.

Tek-CARE160 Audio Bus Wiring

The audio bus for the Tek-CARE160 system is designed to operate on unshielded 18/2 AWG twisted

cable. If a shielded pair cable is used for audio bus wiring, environmental conditions and testing will dic-

tate if the shield should be grounded or floating.

Maximum audio bus cabling distance, including drops to IR160 Audio Stations, must not exceed 1,000'

on each available port. Each IR160 station must be connected to the audio bus.

TekTone recommends pairing up an audio bus cable and data bus cable. For example, the data bus cable

from port 0A should be paired with the audio bus cable from port 0A. These two 2-conductor cables

should be pulled together. Do not use a 4-conductor cable to combine the audio and data bus. This

will produce extreme audio interference and drastically impact audio quality.

Note: The single biggest factor in audio quality for the Tek-CARE160 system is the twist

of the audio bus cabling. Any time a splice is made, or when the audio cable is connected

to the IR160 header, twist the audio cables together as close to the splice as possible.

Tape up the splice so the cables do not separate.

Use care when running audio bus cable. If possible, avoid running the audio bus cable near high voltage

electrical cables. Also, try to neatly install the audio cable, avoiding intertwining it with the data bus

cabling. Make neat splices using terminal strips or piercing connectors, and insulate all splices.

An IR160 Audio Station will open an audio connection when a call placed by any SF121, SF122,

SF123, or PM123 assigned to the same Station ID as the IR160 is answered at a master station.

If a Station ID is dialed from the master station, an audio connection will be opened on all IR160s asso-

ciated with that station ID.

Addressing Room Controllers and Default Behavior

The Tek-CARE160 system is designed to be simple to install. As such, the room controllers are designed

so that a basic system can be brought online with minimal programming.

Each room controller must be addressed to communicate on the data bus using the five position DIP

switch found on the back of the room controller. Available addresses are 0-31.

When assigning addresses to the room controllers, keep in mind which port the room controller is con-

nected to. For purposes of addressing, the two left data bus ports (0A and 0B) and two right data bus

ports (ports 1A and 1B) are tied together. This means that addresses for room controllers connected to

port 0A and port 0B must be unique, but port 0A and port 1A may have addresses duplicated between

them.

Keep detailed notes of the physical addresses and locations of room controllers installed in the facility

using the worksheet in the back of this manual. Without adequate installation notes, system con-

figuration will be extremely time consuming.

Note: No terminating jumper or resistor is required on the data bus. If necessary, the data

bus may also be installed using a star topology. Do not exceed 1,000 feet of cable on any

one data bus run.

The address assigned to the room controller also influences the default behavior of the room controller. If

a controller is addressed as 0-29, the system assumes that the controller will be installed in a single bed

configuration. This is useful for simple one-to-one installations. Room controllers addressed as 30-31 are

defaulted to duty station behavior. These default behaviors are modified during configuration setup if

needed.

Connect Stations

Up to six stations may be connected to each room controller using the header on the back of the room

controller. The leads on the header are paired together to form a point on the room controller. This

means that each header has six points to connect stations to, and one point for data bus connections.

With the wire leads on the connector pointing down, Point 1 is on the left. The illustration below shows

the six available points on the header. The point connections are arranged +-, +-, etc., with each group

of +- connections making up one point.

Tek-CARE160 Station Wiring

When installing wiring to stations, use 22-18 AWG cable. Do not exceed 100 feet of cabling for SF121,

SF122, and SF123 stations. For SF125 stations, do not exceed 50 feet of cabling. Only one station may

be connected to each point. Do not splice multiple stations together on the same point wiring.

One-to-One Installations

In most installations, one room controller will be used as a connection point for all of the station in the

associated room. This provides the simplest software configuration option, but other installation

strategies are available.

In a one-to-one installation, connect the stations to the room controller according to the Points Table on

page 17.

Custom Installations

In other cases, a single room controller can be used to connect stations from multiple rooms or several

beds in a ward-style installation. If stations are installed in this way, keep detailed notes that correlate

the physical room the station is installed in and the DIP switch address of the room controller the sta-

tions are connected to. This information will be needed when creating the system configuration.

Station Connection Instructions

IR160 Audio Stations:IR160 stations are

installed on 2-gang mounting rings or backboxes

using IH121K or IH122K housings.

IR160 Audio Stations require two connections,

one to the audio bus and one to the LI122-series

room controller.

Connect the red wire on the IR160 to the positive

wireof the desired point on the room controller,

and connect the black wire of the same point.

Connect the violet wire on the IR160 station to the

positive leg of the audio bus. Connect the gray

wire on the IR160 station to the negative leg of the

audio bus.

SF121 Single and SF122 Dual Patient Stations: SF121 and SF122 stations are installed on 2-gang

mounting rings or backboxes. Connect the red lead from the station to the positive terminal on the

desired point of the room controller and connect the black lead to the negative terminal of the desired

point on the room controller. If possible, connect the patient station to Point 1. This is the default con-

nection point for patient stations in a single or dual bed installation.

Figure 11 - IR160 Connections

Installation

SF123 Two-Button Pull-Cord Station: SF123 stations are installed on 2-gang mounting rings or back-

boxes. Slide the desired call type insert into the slot on the front of the station. Snap the circuit board

into the front bezel by spreading the face of the bezel while placing the circuit board into the retaining

clips.

Install the rear bracket on the wall or junction box using the two screw holes in the bracket. If a pull

string is used, push an end of the pullstring through the hole in the slider contained on the bracket. Use

the included brass ferrule to crimp onto the string. Trim the string to the appropriate length and insert it

through the hole in the plastic handle. Crimp the remaining ferrule onto the string below the handle.

Note: Push the slider up into the retaining nibs on the rear bracket. Failure to push the

slider up and secure it will result in station damage during installation.

oTo use an SF123 as a Code Blue switch, connect it to Point 2 (Blue and Blue/White) on the

room controller.

oTo use an SF123 as a Bath Emergency switch, connect it to Point 3 (Red and Red/White) on

the room controller.

oTo use an SF123 as an Emergency switch, connect it to Point 4 (Orange and Orange/White) on

the room controller.

oIf a custom call type is desired, note which point the SF123 station is connected to using the

worksheet in the back of this manual. This information will be used during configuration setup.

If an SF123 is to be used as a Check In/Reset station, connect it to any unused point of the room con-

troller. Be sure and note the point that it is connected to, so it can be correctly programmed during con-

figuration setup. For more information about Check In, see Room Level Reset on page 35.

SF125 Duty Station: SF125 stations are installed on 2-gang or 3-gang mounting rings or backboxes.

Connect the red lead from the SF125 LED panel to the positive terminal of the desired point on the

room controller and connect the black wire to the negative terminal of the desired point on the room con-

troller. Connect the positive and negative leads from the toner module to another point. If possible, con-

nect the SF125 LED panel to Point 1, and the toner module (PM578SM) to Point 6. These are the

default point connections for a room controller set up with the duty station present.
