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 trans­mitters. 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 bat­tery, and no check-in from the various transmitters (sensors).

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

must not exceed 500 ft. (152.4 m).

Panel
Receiver orientation is not a problem, as the unique antenna design

of the SpreadNet RF Receiver automatically compensates for vari­ations 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.

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 intercon­nect 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 suc­cessfully 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 out­lined in the SN900-PROG RF Programmer Programming Manual.

Testing the Transmitter and Receiver

After the individual transmitters have been installed and programmed,
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 5-051­136-00).

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:

The physical location of the
Transmitter within the pre­mises.

TX (Transmitter) Type:

Which of the various
SpreadNet Transmitters is
used in that particular loca­tion. (i.e. Door, PIR, Smoke,
etc.)

Check-In Interval: The Su­pervisory 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.

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. The Receiver has been tested and found to comply with the specifications in Part 15 of FCC
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
turning the equipment on and off - the installer is encouraged to correct the interference by one or more
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.

CAUTION: C&K does not support field changes or modifications to any of the SpreadNet RF
equipment unless they are specifically covered in this manual. All adjustments must be made at the
factory under the specific guidelines set forth in our manufacturing processes. Any modification to the
equipment could void the user's authority to operate the equipment and render the equipment in
violation of FCC Part 15, Subpart C, 15.247.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) this device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.

LIMITED WARRANTY

Seller warrants its products to be in conformance with its own plans and specifications and to be free
from defects in materials and workmanship under normal use and service for 18 months from the date
stamp control on the product or for products not having a C&K Systems date stamp, for 12 months
from the date of original purchase, unless the installation instructions or catalogue sets forth a shorter
period, in which case the shorter period shall apply. Seller's obligation shall be limited to repairing or
replacing, at its option, free of charge for materials or labor, any part which is proved not in compliance
with Seller's specifications or proves defective in materials or workmanship under normal use and
service. This warranty is void if the product is altered or improperly repaired or serviced by anyone
other than C&K Systems factory service. For warranty service, return the product transportation
