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 [e-mail] 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-
CAREplatform 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-CAREAppliance Server: The NC475 Tek-CAREAppliance 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-CAREAppliance 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%.

NOTE: Other options for geriatric call cords are available. Contact Sales for details.
Call cords are inserted into their associated patient stations and are subject to the same environmental
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.
