Chapter1—Introduction
The NC377 Paging Interface Adapter is used with TekTone®
NC110, NC150 and NC200 hard-wired nurse call systems to
add radio pocket paging. The interface is connected between
the nurse call system and the radio pocket pager transmitter.
The NC377 Paging InterfaceAdapter detects calls, determines
priority, and then sends information to the NC369 Paging
Transmitter. Program call points so that calls are sent to the
appropriatepager.Information sentincludes calltype androom
number. The pager stamps the time and date.
About This Manual
This manual is designed to assist with installation of this
TekTone®product. Each component of the system is described
withstep-by-step instructionsto facilitatehardware installation
and software configuration.

1. Important: Please use proper splicing techniques.
There will be many splices made to install this unit.
2. Verify proper polarity of input wires (should be +).
3. Use protective eye wear when clipping leads.
Theory of Operation
TekTone®NC110,NC150and NC200nursecall systemsutilize
a lamp select line (wire) to indicate a call on the system. When
idle, these lamp select wires show a +24VDC potential, and
when a call is placed they show a voltage drop of at least
12VDC. This drop, and whether it remains low or pulses, is
used by the interface to determine the call type and priority.
The unit will indicate whether it is a routine level call or a
prioritycall.

Chapter3—Programming Plan
This section outlines the overall programming plan. Refer to
Chapter 4—Programming for step-by-step programming
instructions. (Note: The terms zone and input are used
interchangeablyinthismanual and onthe programmingscreens.)
Before use, perform Global Settings Programming on each
NC377. The NC377 Paging InterfaceAdapter may be ordered
with either 32 or 64 points. Configure each NC377 as either a
master or a slave. There must always be one master, but there
may be up to eight slaves.
1. Each NC377 Paging Interface Adapter will be connected
separately for the global settings programming. After pro-
gramming, they will be connected together for system
operation.
2. The gray crossover cable is used to connect the PC/laptop
totheNC377forprogramming.
3. IfmultipleNC377swillbeconnectedtogether,programthe
slaves first. Only these four fields are programmed on the
slave units:
• Host System (TekTone®)
• UnitID:Slave
• Slave #
• TotalNumber of Contacts(32or 64)
4. LabeleachNC377withitsSlave#orastheMastersoitcan
be identified in the future.
5. Program the master NC377 after all slaves have been pro-
grammed.Contactinputprogrammingisperformedonlyon
themasterNC377.
6. Select TekTone®as the host system on both masters and
slaves.
7. EachNC377hasamaximumcapacityof64inputs,withatotal
576 when all 8 slaves are connected. The contact numbers
run in sequence:
Master 1–64
Slave1 65–128
Slave2 129–192
Slave3 193–256
Slave4 257–320
Slave5 321–384
Slave6 385–448
Slave7 449–512
Slave8 513–576
If an NC377 has fewer than 64 inputs connected, program
only the inputs that are connected. The contacts can be
connectedin anyorder, i.e.1–16 or32–48.
After global settings programming is complete, perform
Contact Input Programming on the master NC377 to program
the inputs being used.

Contact Input Programming
Click on the Contact Settings button at the bottom of the
Global Settings programming screen. The screen shown in
Figure 8 will appear.
Contact inputs must be programmed in order to respond
properly. The master NC377 knows which contacts are on the
slave and which are on the master.
Example: a master with 64 inputs, and 1 attached slave with 16
inputs used. Using the Contact Input programming screen,
programthe first64 contactswiththe informationfor theinputs
connected to the master. Program the next 16 contacts (65–80)
with the information for the inputs connected to the slave.
Programming Contacts for Elapsed Time Reports
If Elapsed Time reports are required, use the room number
and bed identifier as part of the Active, Reset, Pulse 1 and
Pulse 2 messages. The system will compare the time the
input was activated to the time it was reset. It must have
somemethod todetermineone inputfrom another.Since the
room number and bed identifier will not always be the same
as the zone/input number, TekTone®recommends including
the room number and bed identifier in all message types.
Programming Contact Inputs
Start with Zone (input) # 1. Include room number and bed
identifier in all four message types (marked *).
InputAlertType—SelectVoltageAlert-Low.
Room #—Select (1–9999), if applicable. If the nurse call
system uses bed identifiers, also select that (A–E).
ActiveMessage*—Thismessageissenttothepagerwhenthe
zone/inputisactivated.(Example:Room0123A Routine.)
ResetMessage*—This message is sent to the pager when
the zone/input is reset. (Example: Room 1234B Reset,
Room 1234B Cancelled, or Room 1234B Cleared.)
SlowPulsing&FastPulsing—Youmustcheckoneorboth
of these so that the correct message will be sent to the
pager when a slow or fast pulse is detected.
Pulse1Message*—Thismessageissenttothepagerwhen
Pulse1(slowpulse)isactivated.(Example:Room2345C
Emergency.) You must also check Slow Pulsing.
Pulse2Message*—Thismessageissenttothepagerwhen
Pulse2(fastpulse)isactivated.(Example:Room3456D
Smoke Detector.) You must also check Fast Pulsing.

Shift 1, Shift 2 and Shift 3 Pagers (Figure 9)
Enter a Pager ID for each of the message types and
shifts being used. Each shift has three Pager IDs:
• The Active message is sent to the first Pager ID.
• The Pulse 1 (slow pulse) message is sent to the
second(middle)PagerID.
• The Pulse 2 (fast pulse) message is sent to the third
PagerID.
The Shift Schedule checkbox in the Global Settings
screen determines which shifts must have Pager IDs
assigned:
• Ifyouchecked ShiftSchedule inthe GlobalSettings
screen, fill in Shift 1, Shift 2 and Shift 3 Pagers.
• If you did not check Shift Schedule in the Global
Settings screen, fill in Shift 1 Pager.
Use this formula to convert the pager’s CAP code to its
corresponding Pager ID (add leading zeros to make 7
digits): PagerID =[(pager’s CAPcode ×8)+10000]
If a shift’s message type is not being used, enter 7 zeros
as its Pager ID.
EscalationPagers(Figure9)—Thesepagersaresentacall
ifitisnotresetwithinacertainperiodoftime.Checkthe
boxandenteraPagerIDforeachoftheshiftsbeingused.
ThefirstPagerIDisforshift1,thesecondPagerIDisfor

Use this formula to convert the pager’s CAP code to its
corresponding Pager ID (add leading zeros to make 7
digits): PagerID =[(pager’s CAPcode ×8)+10000]
If a shift is not being used, enter 7 zeros as its Pager ID.
Repeat—Choices are 0–5. Do not use the RUR setting
(Repeat until Reset), because it cancels escalations.

AWord about ESD(Electrostatic Discharge)
What Is It?
Static electricity is a result of triboelectric charging of two
dissimilar non-conductive materials that are rubbed together,
such as rubbing your feet on a carpet on a cold winter day or in
a dry climate. 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 dependant
on the materials being rubbed together, humidity, the rate of
separation, 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 dischargecurrent canjumpto anynearby metallic
or non-metallic 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 discharge current passes
through internal components, these components may be
damaged or their operation degraded.
What Can We Do About It?
Themanufacturer ofthe nursecallequipment hasalready taken
steps to protect the equipment from electrostatic discharge
(ESD) effects. Our peripheral equipment has been tested and
listed by ULR 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 measures can
be taken.
• Groundallexposedmetalsurfaces.Groundingshouldbeto
a #16 gauge or larger conductor.
• Install nurse call system wiring in metal conduit. This
conduit may be used to ground panels.
• Use shielded cable for nurse call system station-to-station
wiring. The use of open conductors invites inductive cou-
pling of discharge currents, which can cause the same
problems as direct discharge currents.
• Ground 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
followingprecautions willhelp. Removethe callcordor 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, causing 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.
