Mounting Procedure
To mount the SN914-SZR, orient
theunitasshowninFigure2.Loosen
the cover retaining screw on the
front of the Receiver and open the
front panel. The front and rear
housingsmaybeseparatedforeasier
installation.Removetheknock-outs
for wiring the Receiver to the con-
trol panel.
Use the rear cover as a template
to mark the mounting holes (see
Figure 2). Drill the holes as neces-
sary. The hole at the top center of
the rear housing is designed for
mounting the Receiver to the wall.
The tab also serves as a removable
stand-off when mounting the Re-
ceivertothetopoftheControlPanel
housing (see Figure 1). The plastic
tab should be removed as it will
interfere with the proper closing of
the control panel door.
Receiver Wall Tamper
Both a cover and a wall tamper are
providedwithasingletamperswitch.
To
activate the wall tamper , remove
the knock-out in the rear housing
and install a screw in the wall, leav-
ing enough of the screw head exposed to depress the tamper switch
when the cover is closed.
Wiring the Receiver
Pullthe6-wirecable(common,
power,alarm,and trouble) and
the 2-wire cable (tamper)
through the rear cover. Mount
the Receiver in the desired lo-
cation as shown in Figure 1.
Connect the SN914-SZR Re-
ceiver to the Control Panel as
shown in Figure 3. Be sure to
observe polarity. The SN914-
SZR derives its power from
the Control Panel via the V+
(to panel AUX+) and V- (to
panelCorGND)terminals.The

SpreadNet®
Model SN914-SZR
RF Single Zone Receiver
Installation Instructions
The SpreadNet®Model SN914-SZR is a Single Zone Receiver in
the C&K family of Spread Spectrum RF products. The SN914-SZR
is a stand-alone product which supports up to 32 SpreadNet trans-
mitters. The SN914-SZR provides both a Form "C" Alarm Relay
output and a Form "A" Trouble Relay output. The SN914-SZR is not
suitable for use with smoke detectors.
Special features include an alarm and trouble event memory. The
SN914-SZR Single Zone Receiver detects alarms, tamper, low bat-
tery, and no check-in from the various transmitters (sensors).

• 900 MHz Spread Spectrum • Wall/Cover Tamper
• Noise & RF Immunity • Suitable for UL Grade B
Service
Mounting Location
The RF Receiver may either be mounted on the wall or on the control
panel housing. For optimum performance, the Receiver should be
mounted on the wall. The distance between the Receiver and Control
Panel
must not exceed 500 ft. (152.4 m).
Receiver orientation is not a problem, as the unique antenna design
of the SpreadNet RF Receiver automatically compensates for vari-
ations in signal direction. Two antennas orientated at right angles
virtually eliminate problems associated with noise and signal fading.
When choosing a location to install the SN914-SZR RF Receiver,
you should avoid areas near screens, metal window frames, circuit
breaker boxes, metal air conditioner and heater ducts. These areas
interfere with the receiver's ability to pick up signals or are sources
of high noise and radio frequency interference.

FCC NOTICE
The Model SN914-SZR generates and uses radio frequency energy. If not installed and used in
accordance with the manufacturer's instructions, it may cause interference to radio and television
reception.TheReceiverhasbeentestedandfound tocomplywiththespecificationsinPart15ofFCC
Rules for Class B Computing Devices and FCC Part 15 Subpart C, Specifications for Intentional
Spread Spectrum Radiators.
If this equipment causes interference to radio or television reception - which can be determined by
turningtheequipmentonandoff-theinstallerisencouragedtocorrecttheinterferencebyoneormore
of the following measures: 1) Reorient the antenna of the radio/television. 2) Connect the AC
transformer to a different outlet so the control panel and radio/television are on different branch
circuits. 3) Relocate the control panel with respect to the radio/television.
If necessary, the installer should consult an experienced radio/television technician for additional
suggestions, or send for the "Interference Handbook" prepared by the Federal Communications
Commission. This booklet is available from the U.S. Government Printing Office, Washington D.C.,
20402, stock number 004-000-00450-7.

Figure 4 - Connecting the RF Programmer
Programming and Set-Up
The SN914-SZR Receiver is programmed using the SN900-PROG
Handheld Programmer. Connect the SN900-PROG Programmer to
connector P1 on the Receiver, as shown above, using the intercon-
nect cable supplied with the Programmer. In order to determine the
Channel # and Property Code to be used, the Programmer must be
connected to the Receiver prior to programming any of the system's
transmitters.
When selection of the Channel and Property Codes has been suc-
cessfully completed, the system transmitters may be programmed.
Refer to the Installation Instructions included with each Transmitter
for proper setup.
Programming the Receiver
Program the SN914-SZR Receiver following the instructions out-
lined in the SN900-PROG RF Programmer Programming Manual.
Testing the Transmitter and Receiver
Aftertheindividualtransmittershavebeeninstalledandprogrammed,
the RF Programmer can be used with the RF Receiver to measure
transmitter reception characteristics. For additional details, refer to
the SN900-PROG RF Programmer Programming Manual (P/N 5-051-
136-00).
Termination Summary Label
After the system has been installed, programmed and tested, the
installer should complete the Termination Summary Label, included
with the installation kit. A partial sample of the Termination Label is
shown below with an assortment of zones filled out.
Property Code: Identifies the Transmitter and Receiver as belonging
to a particular system.
Transmitter Location:
Thephysicallocationofthe
Transmitter within the pre-
mises.
TX (Transmitter) Type:
Which of the various
SpreadNet Transmitters is
usedinthatparticularloca-
tion.(i.e.Door,PIR,Smoke,
etc.)
Check-InInterval:TheSu-
pervisory Rate for all Transmitters (in seconds). May range from 30 to
300 seconds in 10 second intervals, or 0 for unsupervised.
SNR: The Signal-to-Noise Ratio of the Transmitter showing Signal
strength and Noise level in decibels (dB).
Battery Date: The date the batteries were installed or last replaced.
Upon completion, the label may then be placed inside the rear cover of the
RF Receiver or inside the Control Panel for future reference.
NOTE: The SN914-SZR Receiver is suitable for UL Grade B service.
