A Word about ESD (Electrostatic Discharge)
A Word about ESD (Electrostatic Discharge)
What Is It? Static electricity is a result of triboelectric charging of two dissimilar nonconductive mater-
ials that are rubbed together, such as rubbing your feet on a carpet on a cold winter day or in a dry cli-
mate. The resulting charge is detected when you reach out to touch a doorknob or some other metallic
object. The resulting discharge may only be startling or, in severe cases, it may even be painful. The
actual electrical charge is dependent on the materials being rubbed together, humidity, the rate of sep-
aration, and other factors.
What Can It Do? While this effect may be disturbing to humans, the effect on electronic equipment is
often more serious, ranging from operational disruption to actual component damage. These effects result
from the high voltages that may be developed. The simple act of walking across a carpet may develop as
much as 30,000 volts, and changing a bed sheet may create a charge of 100,000 volts or more. Such
voltages readily cause arcing (the spark that can be observed when you grab a doorknob after walking
across a carpet, etc.). The arcing is evidence of the discharge path. Due to the high voltage involved, the
discharge current can jump to any nearby metallic or nonmetallic object. If the discharge is to or through
an electronic device, such as the nurse call system, the operation of the device may be affected. If the dis-
charge current passes through internal components, these components may be damaged or their operation
degraded.
What Can We Do About It? The manufacturer of the nurse call equipment has already taken steps to
protect the equipment from electrostatic discharge (ESD) effects. Our peripheral equipment has been
tested and listed by UL®to withstand discharges of up to 30K volts. However, since the cause is not in
the equipment, but in the environment, further measures are required of the installer and the user to
achieve complete protection.
What the Installer Can Do: In humid climates or in places where the relative humidity is kept at 65%
or greater, there will likely be few problems with ESD. Where problems may occur the following meas-
ures can be taken.
lGround all exposed metal surfaces. Grounding should be to a #16 gauge or larger conductor.
lInstall nurse call system wiring in metal conduit. This conduit may be used to ground panels.
lUse shielded cable (where specified) for nurse call system station-to-station wiring. The use of
open conductors invites inductive coupling of discharge currents, which can cause the same prob-
lems as direct discharge currents.
lGround your body before handling system components. This can be done by using a wrist strap,
or simply by contacting a grounded metal surface. Use caution to avoid hazardous voltages while
grounded.
What the User Can Do: The most common generation of ESD in hospitals is due to changing linen on
hospital beds while the patient call cord or pillow speaker is still connected to the nurse call system.
The following precautions will help.
Remove the call cord or pillow speaker from the bed before changing the linen. It will be necessary for
the nursing staff to discharge themselves by contacting a grounded metal object before placing the call
cord or pillow speaker back on the bed; otherwise a spark will jump to the nurse call equipment, caus-
ing the very damage they are trying to avoid. To avoid a shock while discharging static electricity on
the body, hold a metal object, such as a key, and use that object to contact the grounded surface.
This information is provided to make you aware of ESD problems so that precautions may be taken to
avoid damage and disruption of system operation.

System Introduction
Welcome to the installation manual for the Tek-CARE300III Nurse Call System. This manual will walk
you through the installation and configuration process and will cover system operation. If you have any
questions at any point during the installation process, contact our Technical Support Department by
email at teksupt@tektone.com or by phone at 800.327.8466 or 828.524.9967. Choose Option 3 for Tech-
nical Support.
The Tek-CARE300III Nurse Call System is a supervised microprocessor-based nurse call system that
provides a complete range of two-way audio and visual signaling combined with programmable system
configuration and information tools. These functions permit easy communication between facility staff
and patients, as well as between staff members.
The NC356CE Module is a third-generation module designed to be networked on the Tek-
CAREplatform and be programmed using the LS450 Config Tool software. When combined with an
NC475 Appliance Server, this module provides advanced features like event logging and reporting,
mobile apps, email, and much more.
The system is completed by a variety of patient stations and peripheral devices to meet all staff and
patient needs. The equipment uses plug-in modular components, allowing them to be expanded and inter-
changed as needed in existing and new facilities.

System Introduction
System Installation
System Installation
Read the following information prior to installing the Tek-CARE300III system equipment. The installer
must be familiar with the system and its installation requirements and guidelines.
1. Determine equipment locations.
2. Install housings.
3. Install system wiring.
4. Use ohmmeter to check for shorts and grounds in system wiring. NOTE: This is a critical and
necessary step for avoiding installation problems later. When checking for shorts between shields,
remember that the provided interconnection cable harnesses already have the shields connected
together internally as a preparation to their introduction to the central equipment’s ground.
5. Connect equipment to system wiring. See Troubleshooting Tip below.
6. Power up the equipment.
7. Set patient, staff and duty station addresses. Refer to Figure 7 on page 15.
8. Program the Tek-CARE system with the LS450 Config Tool.
9. Verify connections.
10. Perform full operational test of the system, including all peripheral devices.
11. Train system operators.
TROUBLESHOOTING TIP: Before the above process begins, consider this brief comment on
troubleshooting. The transition between Steps 9 and 10 is a very important one. It is during this phase of
the installation process that the system is first powered up with field wiring, patient stations and peri-
pheral devices. This is the time when most installers encounter problems with wiring and equipment.
Problems to Avoid
lDo not use wire nuts for wire connections. Wire connections must be made with compression-
type connectors, rated for stranded wire, that use a ratcheting-type tool for installation.
lDo not short shields together, as this allows for noise transference from the data lines to the audio
lines.
lUnused conductors from the plug-on wiring harnesses of various devices must be taped up to pre-
vent the ends of the cut wires from coming into contact with other points (circuit boards, back
boxes, etc.).
lDo not exceed the maximum specified cable distances. Pay extra attention during the planning
stages when running cable to areas that add “hidden” length to cable runs.
lThe capacitance on the data wires is critical (<24 pF/ft.). If the cable capacitance exceeds this
level, data signal degradation can occur and interfere with normal system operation.
lDo not run system cabling in close proximity to other electrical system cables or building power
cables. These systems can induce noise, resulting in system operational problems and/or audio
noise.

installation of all system equipment, cabling and enclosures must be in accordance with the National
Electrical Code (ANSI/NFPA 70-1999), the Healthcare Facilities Code (ANSI/NFPA 99-1999), and all
applicable state and local codes.
NC356CE Module: The NC356CE is the core piece of equipment for the Tek-CARE300III Nurse Call
System. All master stations and patient stations connect to it. The NC356CE has two ports (0 and 1) and
will support six master stations (three per port), 64 patient stations (addresses 0-31 per port). Up to 20
modules can be networked together on the Tek-CARE system. The NC356CE must be located near a
dedicated 115VAC outlet connected to the Emergency Branch of the facility's Essential Electrical Sys-
tem (i.e., connected to a backup power source), suitable for computer-grade equipment. The device must
be shelf, desk, or rack mounted in an area with a consistent temperature and relative humidity not
exceeding 95%.
NOTE: All NC356CEs require the external PK356 supplemental power supply, which is
included.
PK356 Supplemental Power Supply: The PK356 provides DC power to the system. The PK356 power
supply must always be powered down when the central equipment is powered down. Therefore sug-
gested that the PK356 and the NC356CE be plugged into a power strip which is connected to 120AC.
Do not locate these devices near other electrical systems, such as fire alarm panels, electrical motors, air
conditioning equipment, etc. The PK356 must be located near a dedicated 115VAC outlet connected to
the Emergency Power Circuit (i.e., connected to a backup power source), suitable for computer-grade
equipment, and within 2' of the NC356CE. Interconnect the NC356CE and the PK356 using the
provided interconnection cable.
NC475 Tek-CAREAppliance Server: The NC475 Tek-CAREAppliance Server is the proprietary nurse
call appliance server which adds various features and functionality to the Tek-CARE300III Nurse Call
System. It can be available as either a headless appliance server or can be supplies with a 22" touch-
screen monitor and wireless mouse. It has two network interface ports and six RS232 serial ports. The
NC475 Tek-CAREAppliance Server may be powered by 110-220 VAC line power. An uninterruptible
power supply must be used. The power supply and NC475 must be connected to a generator-backed AC
circuit suitable for life safety equipment. For more information, see IL1012 NC475 Tek-CARE Appli-
ance Server Manual.
NC415AV/NC404TS Master Stations: The NC415AV and NC404TS are used by the facility staff to
interact and communicate with patients through the nurse call system. The staff may answer calls via
loudspeaker or by using the handset for calls that require more privacy. The master station is typically
located on a desk or counter top or can be wall mounted, within easy reach of the facility staff. The oper-
ating environment for the master station is approximately 26°C and relative humidity not exceeding
80%. For more information on the NC404TS, see IL1052 NC404TS Installation and Operation Manual.

IR3xx-series Stations—General Information: All of the IR3xx-series devices’ electronics are mounted
on a flame-retardant ABS plastic panel. Users must observe ESD precautions [see A Word about ESD
(Electrostatic Discharge) on page 4] when handling these devices as they may be damaged if improp-
erly handled. Each of the IR3xx-series stations require a unique address, which is set using the on-board
dip switch. Plug-on connectors are provided for easy installation. The IR300-series must be located cent-
ral to the various peripheral devices that are connected to it. See IR3xx-series Station—General Inform-
ation on page 9 for additional details.
The IR3xx-series stations use the Steel City H3BD back box with a 3GC plaster ring. Refer to Figure 1
below for mounting. The minimum dimensions for the back box must be not less than 8.6" × 4.5" × 2.5",
and the minimum clearance from current carrying parts to dead metal parts must be no less than 0.5". If a
station has a pillow speaker module, a bigger back box is recommended. These devices are typically loc-
ated for convenience, most commonly at the head of the patient’s bed, unless specified otherwise. The
IR3xx-series stations must be located within 1000′ feet of the NC356CE, and so that furniture, curtains
and other features do not interfere with audio communication. See the wiring diagrams at the end of this
manual for additional requirements. NOTE: There are additional guidelines for station location in the
wiring installation section. The operating environment for the IR3xx-series stations is 10–40°C with rel-
ative humidity not exceeding 80%. See the Wiring Installation on page 12 for additional information.

SF380 Single Patient Stations: The SF380 stations generate routine, cord-out and bath call placement
signals. These stations are mounted on single-gang boxes. The stations support both code and bath sig-
nals.
IR311 Single and IR312 Dual Patient Replacement Stations: The IR311 and IR312 stations are avail-
able as replacements. The jacks are 8P8C type—one for the IR311 and two for the IR312. Additional
headers are provided for specific pillow speaker-only connections—one for the IR311 and two for the
IR312 (refer to Figure 28 on page 43). These stations can interface with the PM311C/PM312C Intercom
Modules and the PM321B/PM322B Lamp Control Modules. See IR3xx-series Station—General Inform-
ation on page 9 for additional details.
IR319-series Single, IR320-series Dual Patient Stations: The IR319-series and IR320-series are
identical to the IR301-series and IR302-series, with the exception of the jack type and added pillow
speaker function control lines. The jacks are DIN type—one for the IR319-series and two for the IR320-
series. Additional headers are provided for specific pillow speaker-only connections—one for the IR319-
series and two for the IR320-series (refer to Figure 28 on page 43). These stations can interface with the
PM311C/PM312C Intercom Modules and the PM321B/PM322B Lamp Control Modules. See IR3xx-
series Station—General Information on page 9 for additional details.
PM311C/PM312C Pillow Speaker Intercom Modules: The PM311C (for IR311-series or IR319-series)
and PM312C (for IR312-series or IR320-series) modules connect to the patient station and allow the
nurse call system audio to be redirected from the patient station to the pillow speaker connected to it.
SF301PI series, SF301DIG, SF401DIG or SF41-series pillow speakers are required for this application. If
the connected call cord or pillow speaker does not support this function, the audio reverts back to the
patient station. The modules plug directly onto the back of patient stations and are subject to the same
environmental requirements.
PM321B/PM322B Light Control Modules: The PM321B (for IR311-series or IR319-series) and
PM322B (for IR312-series or IR320-series) modules allow SF301PL series, SF301DIG, SF401DIG or
SF41-series pillow speakers to activate control relays that can be linked via dry contacts to control over-
head and table lighting. The control relays are brought out on a separate header. (Refer to Figure 26 on
page 41.) WARNING: Connect only Class 2, Power Limited circuits (in accordance with ANSI/NFPA
70, ANSI/NFPA 99 and ANSI/UL®1069) to the PM321B or PM322B. If in doubt, contact the factory.
The modules plug directly onto the back of patient stations and are subject to the same environmental
requirements.
IR318 Resident Pull String Speaker Station: The IR318 is an audio-visual resident station for use when
a pull string is desired as compared to a push-button call cord. The station provides a speaker for two-
way audio communication, a pull string for call placement, a call reset button and indicators for call
placement assurance and in-use status. See IR3xx-series Station—General Information on page 9 for
additional details.
RY351B Hill-Rom®SideCom®Adapter: The RY351B provides an interface for the Hill-Rom SideCom
bed to the IR311-series, IR319-series, IR312-series (requires two RY351B) and IR320-series (requires
two RY351B) patient stations. This enables the intercom, call placement indication, and in-use indic-
ation functions of the SideCom bed to work with the nurse call system. The SideCom’s lamp and light-
ing controls are connected to the lighting control system and do not need to interface with the nurse call
system. The RY351B interface also detects the disconnection of the (low voltage) signaling cable from
the wall receptacle and places a noncancellable call to the programmed nursing Master Station. The
RY351B electronics are mounted on an aluminum bracket that can be used to mount the device on a
Steel City two-gang back box, part number 52171-1/2 and 3/4 with 52-C-13 single gang adapter ring.
The RY351B must be within 6′ of the patient station to which it is connected. The Hill-Rom P376 series
plug-in adapter must be installed within 10′ of the RY351B. The operating environment for the RY351B
is 10-40°C with relative humidity not exceeding 80%.

requirements.
LI38x/LI38xLED Dome Light: The LI380 provides visual indication from the IR3xx-series stations and
associated peripheral devices. Four bulbs and four colored lenses (LI380), four colored LEDs and single
lens (LI380LED) allow the device to indicate all system call types with various flash rates and com-
binations. When connected to an IR315-series Duty Station, the light functions as a zone light. The LI
series dome lights use the Steel City H2BD backbox with a 2GC plaster ring; refer to Figure 2 on page
8for mounting. The minimum dimensions for the backbox must be not less than 4"×4"×1½", and the
minimum clearance from current carrying parts to dead metal parts must be no less than 0.5". The dome
light must be located above or beside the doorway of the associated room, and must be mounted so that
unobstructed visibility is provided. When being used as a zone light, the LI380 must be mounted at cor-
ridor heads or junctions so that facility staff members can readily identify the associated zone area. The
LI380 must be within 50' of the patient station it is connected to. The LI380 requires a specific jumper
connection to be made (from pin 1 of the 8-pin connector to pin 6 of the 15-pin connector on the asso-
ciated patient station) to disable the lamp fault detection circuitry of the associated IR3xx-series station
it is connected to (refer to Figure 21 on page 36). The operating environment for the LI380 is 10-40°C
with relative humidity not exceeding 80%. See Wiring Installation on page 12 for additional details.
LI386 Dome/Zone Light: The LI386 provides the same indication functionality as the LI380 and
includes support electronics to make it an addressable device. This device is suitable for stand-alone
equipment applications and zone indication applications. NOTE: This device does not support all of the
standard peripheral devices (refer to Figure 23 on page 38). Turning on dip switch 7 activates the zone
indication feature. See LI380 Dome Light (above) for location and environmental requirements.
SF-series Peripheral Devices—General Information: The SF-series peripheral devices’ electronics are
mounted on flame retardant ABS plastic faceplates. SF-series devices must be mounted within 50' of the
patient station to which it will be connected. They are mounted on single-gang rings or boxes (minimum
ring opening not to be less than 1¾" × 2¾"). The minimum clearance from current carrying parts to dead
metal parts must be no less than 0.5". Plug-on connectors are provided for easy installation. See the Wir-
ing Installation on page 12 for additional details.

SF337C Bath/Emergency Switch: The SF337C allows patients to initiate a bath call to inform staff
members that they require assistance in bathroom or restroom areas. The device is designed to be moun-
ted in wet areas when properly installed (using the included gaskets for the panel and screws). The
device can be activated by hand with the red pull down lever, or by pull-cord (if installed). It also
provides a call placed indicator.
This device is typically located in toilet, bath and shower areas, and is mounted at a height convenient
for use. If the device is being mounted to a tile wall or other irregular surface, the installer must provide
extra sealant to fill tile seam points or other gaps. If the device is being used with pull-cord activation,
the included cord must be installed through the guide tab and red pull-down lever and secured with a
double knot. Mounting location and cord length must be such that a prone patient can reach the call
cord to activate the device. The operating environment for the SF337C is 10-40°C, and the device is
water resistant when correctly installed. See SF-series Peripheral Devices—General Information for
additional details.
SF340B Bath/Emergency Switch: The SF340B provides the same operational functionality as the
SF337C, except that it is not suitable for moist or wet environments. The operating environment for the
SF340B is 10-40°C with relative humidity not exceeding 80%. See SF-series Peripheral Devices—Gen-
eral Information for additional details.
SF341B Supervised Code Call Station: The SF341B allows patients and staff members to initiate high
priority “CODE” calls. The device incorporates a supervisory circuit to monitor the wiring connection to
the patient station, as well as a call placed indicator. The device is activated by hand operation of the
blue pull-down lever. The SF341B must be located for convenient operation in areas that require code
call initiation (such as ICU/CCU areas). The environment for the SF341B is 10-40°C with relative humid-
ity not exceeding 80%. See SF-series Peripheral Devices—General Information for additional details.
SF381 Standalone Emergency Switch: The SF381 provides the same operational functionality as the
SF337C, except that it is not suitable for moist or wet environments. The operating environment for the
SF381 is 10-40°C with relative humidity not exceeding 80%. See SF-series Peripheral Devices—Gen-
eral Information for additional details. The SF381 differs electronically from the SF337C or SF340B
devices in that it incorporates electronic circuitry to support standalone functionality similar to that of
an IR3xx-series Station. Information that applies to this aspect of the device can be found in the first
paragraph of IR3xx-series Station—General Information.
SF382 Standalone Code Call Station: The SF382 provides the same operational functionality as the
SF341B. The operating environment for the SF382 is 10-40°C with relative humidity not exceeding
80%. See SF-series Peripheral Devices—General Information for additional details. The SF382 differs
electronically from the SF341B device in that it incorporates electronic circuitry to support standalone
functionality similar to that of an IR3xx-series Station. Information that applies to this aspect of the
device can be found in the first paragraph of IR3xx-series Station—General Information.
SF350B Nurse/Aide Presence Station: The SF350B works in conjunction with the nurse/aide presence
registration features of the nurse call system. It allows nurse and aide staff to register their presence with
a simple button push, and facilitates the transfer of nurse follower features from room to room (when
activated at the master station). A nurse registration button and indicator, and an aide registration button
and indicator are provided. The SF350B must be located for staff convenience, typically within the asso-
ciated room near its entrance. The environment for the SF350B is 10-40°C with relative humidity not
exceeding 80%. See SF-series Peripheral Devices—General Information for additional details.

Wiring Installation
The bulk of the necessary wiring information can be found in the wiring diagrams at the end of this
manual.
IMPORTANT: Liberty AV Solutions cable or equivalent is required for this install-
ation. Using other types of cable can cause various issues with the system and confusion
during installation.
Refer to Figure 18 on page 33 for additional cable specifications.
The NC356CE includes two master station ports, two patient station ports and PK356 port on the rear of
the module. Interconnection cable harnesses, CT318, (also known as “whip” or “pigtail” connectors) are
provided for the two patient station ports with the central equipment. Connect the PK356 Power Supply
to the NC356CE using the included 15-pin serial cable. Each port type is separately described below,
with the specifics of connection.

Audio Adjustments
Adjustments can be made to change or improve the volume and quality of the audio on the Tek-
CARE300III system. There are basically three adjustments that can be made by installers to affect the
audio of the system. Speaker volume and microphone gains can be adjusted for each station using the
LS450 Config Tool software, and there is an audio trim pot for each audio bus port.
The audio bus of the Tek-CARE300III is susceptible to electronic noise induced by other building sys-
tems. Most of this noise can be removed by use of the trim pots on each audio bus port. In order to reach
the trim pots, a very small flathead screwdriver (1/16" blade) is required.
1. Connect an NC415AV or NC404TS Master Station directly to the NC356CE module using a
short patch cable. You must be able to reach both the NC356CE module and the
NC415AV/NC404TS Master Station at the same time during this procedure.
2. Dial a Station ID that is connected to Port 0 from the master station, and establish an audio con-
nection using the Talk button, not the handset, of the master station.
3. Release the TALK button. You should now have an open audio channel, and be listening to the
station you dialed through the speaker on the connected master station.
4. Using a flathead screwdriver, turn the potentiometer
for Port 0 approximately 12 turns clockwise. This
ensures that the potentiometer is maxed out. Note
that the potentiometer will not stop at the end of its
travel, but will spin freely. This is normal.
5. With the potentiometer fully clockwise, you may
hear a considerable amount of background and data
noise on the open audio channel. This is normal.
6. Begin turning the potentiometer counterclockwise. After six full rotations, the potentiometer will
be in the center of its travel.
7. Make small clockwise and counterclockwise adjustments to the potentiometer while listening to
the audio connection. Too far clockwise or counterclockwise will induce noise on the audio bus.
8. Adjust the potentiometer so that the noise level on the channel is as low as possible. Remove
your screwdriver from the potentiometer and clear the audio connection.
Finally, dial a Station ID that is connected to Port 1 from the master station. Repeat the process outlined
above while adjusting the audio trim potentiometer for Port 1 of the NC356CE module.

Patient Station Ports: Each patient station port supports up to 32 patient stations and a maximum of
1000′ feet of interconnecting cable. This maximum distance does not include peripheral wiring con-
nections, and only reflects the common wiring between all of the stations on that particular port and
their associated connection to the NC356CE. The following must be observed for patient station wiring:
lDo not run cables to the bottom of the patient station back boxes, because there is no access for
cable passage.
lAt all splice points, the common cable shields must be kept isolated from all other circuits and
fed through as any other conductor would be. The shields must be continuous through the entire
run and must be isolated and taped back at the end of the run. When connecting the common
cable to the central equipment, the shields will be connected to the shields of the interconnecting
wire harness, CT318 (also known as “whip” or “pigtail” connector).
lEach patient station port has one audio path. If a system is known to have a small quantity of sta-
tions that will occupy only one or two ports, the installer should consider redistributing the
devices evenly among all of the available station ports. This enables all of the available audio
paths for use in system operation, allowing two simultaneous paths, and increasing call response
efficiency.

System Installation
NC356CE Module: This device is entirely configured through the LS450 Config Tool software. The
NC356CE enables legacy stations to function on the Tek-CARENetwork.
Things to consider when updating to an NC356CE from an NC351A:
lGo over existing "as-built" wiring plans to review where wiring will need to be upgraded. If exist-
ing wiring plans cannot be found, a site survey must be done to configure the current wiring topo-
logy.
lKeep in mind the NC356CE can only hold 64 stations per CE, with addresses of 0-31 per station
port. Any original station addresses above 31 needs to be revised to fit the addressing scheme for
the station port on the NC356CE.
lIf updating the system from a PM456 to an NC356CE, the existing CT318RT connector will not
fit on the NC356CE. The CT318 included with the NC356CE will fit the module perfectly.
However, the header on the CT318 may be swapped with the CT318RT right angle connector
header to avoid rewiring.
On the front of the NC356CE 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 module itself. See the
dip switch diagram for the NC356CE below.
Figure 9 - Gen2 Tek-CAREModule Dip Switch Diagram
IR3xx-series Stations: These devices are addressed by turning on and off the 7 available dip switches
located on each device. Stations that occupy the same port must all have unique addresses (ranging from
00 to 31). The 7-switch dip switch uses a binary configuration method (1 has a value of 1, 2 a value of
2, 3 a value of 4, 4 a value of 8, etc.). Using these values, the station address is represented by the sum
of the values of all switches that are turned on. For example, if switches 2 (value 2) and 5 (value 16) are
turned on, the address is 18 (2+16=18). Using this method, values of 00 to 31 can be generated using
only switches 1 through 6.
The four-digit Station ID is an amalgamation of the Module Address, the port the station is plugged
into, and the dipswitch address of the station. For example. if the module address is 3 and the station is
addressed 30 in the lower port 0, the station ID would be 0330. If the station is addressed as 1 in the
higher port 1, it would be 0332. The LS450 Config Tool software will display these station IDs on the
Stations page which should be edited to be architectural room names. See IL855 LS450 Config Tool
Manual for further details.
IR315 Duty Station: In addition to the dip switch address settings, the IR315 also has a tone control
adjustment (via three pin header) to set annunciation tone levels.
SF380 Single Patient Station: Refer to Figure 29 on page 44 for dip switch settings. NOTE: SF380 sta-
tions must be programmed for Personal Attn. Priority Level.
SF381 Standalone Bath Station/SF382 Standalone Code Station: Refer to Figure 31 on page 46 for
dip switch and jumper (shunt) settings.

Patient Station Operation
This section refers to the following types of patient stations: IR3xx-series and SF380-series. Refer to Fig-
ure 10 on page 18 and Figure 11 on page 19 for the locations, names and functions of the controls and
indicators of these devices. A brief description of the operating controls for patient stations follows.
Call-Placed Light: The call-placed light indicates when any call is placed from the patient station.
Reset Switch/In-Use Light: The reset button cancels a call placed from the station. The light illuminates
whenever communications from the master station is engaged.
Call Cord Receptacle: The round DIN receptacle found on IR319-series and IR320-series stations uses
SF401EX strain relief cables, SF4xx-series call cords, and SF4xx-series pillow speakers.
NOTE: There are a number of older call cord receptacle types. Please contact tech support
for more details.
NOTE: Only call cords and pillow speakers that are tested with and UL approved for use
with TekTone nurse call equipment may be directly connected to the DIN call cord recept-
acle on TekTone patient stations. Other methods are available for properly isolated con-
nections of hospital beds and other ancillary equipment.
Pull Cord: The IR318B provides an integral call-initiating pull cord. Patients simply pull on the cord to
trigger a call.
Speaker/Microphone: The speaker/microphone is used for voice communications and tone signaling.
Due to the high sensitivity of the speaker/microphone, the patient does not need to move close to the
device, or to speak above normal levels to be heard.
To Place a Call:
1. Press the call button on the end of the call cord, or press the red call button with the nurse or
cross symbol on the pillow speaker, or pull on the IR318 call cord. (See Figure 15 and Figure
16 on page 22.)
2. Call placement can be verified by the flashing of the Call-Placed Light. A “Cord-Out” call will
automatically be placed if a call cord or pillow speaker is removed. NOTE: SF380 stations must
be programmed for Personal Attn. Priority Level.
To Answer a Call:
Reply in a normal voice when spoken to. The audio communication will normally come from the patient
station. If IR3xx-series are used with PM311C or PM312C Pillow Speaker Module, audio com-
munications will be to and from the intercom-capable pillow speaker. Calls placed from SF380-series sta-
tions must be handled in person, because the SF380 do not incorporate audio communication.
To Cancel a Call:
1. Press the reset button until the call-placed LED is extinguished.
2. Canceling a call placed by the removal of a call cord can be accomplished by replacing the call
cord.
Television Controls:
For the IR3xx-series patient stations with pillow speakers, press the button labeled “TV” or with the tele-
vision symbol. If the television is off, the first press will turn it on. Each successive press will step
through the channels until the television turns back off. The volume may be adjusted by rotating the
volume control until the desired level is reached. This control only adjusts television audio levels.
NOTE: Connect only UL®1410 approved hospital-grade TVs in this application.
