Please Read Carefully and Save
This instruction manual contains important information
about the installation and operation of bells. Purchasers
who install bells for use by others must leave this manual
or a copy of it with the user.
General Description
The National Fire Protection Association has published
codes, standards, and recommended practices for the installation and use of the above appliances. It is recommended that the installer be familiar with these
requirements, with local codes, and any special require-
ments of the authority having jurisdiction.
System Sensor supplies bells for nearly all sprinkler/fire
alarm/burglar applications.
These bells are intended to be connected to alarm indicat-
ing circuits of UL listed fire alarm control panels. The SSM
These instructions apply to all System Sensor bells in the
series. Read all instructions carefully before beginning. Follow only those instructions that apply to the model you are
series is polarized to enable supervision of the installation
wiring. The SSM bells require 24 VDC and the SSV bells re-
quire 120 VAC.
installing.
CAUTION
Do not use in potentially explosive atmospheres.
Do not leave any unused wires exposed.
D770-11-00 1 I56-674-04
Before installing any alarm device, be thoroughly familiar
with:
NFPA 72: National Fire Alarm Code
NFPA 13: Installation of Sprinkler Systems
NFPA 25: Inspection, Testing, and Maintenance of Water-
Based Fire Protection Systems
Other applicable NFPA standards, local codes, and the requirements of the authority having jurisdiction.
Failure to follow these directions may result in failure of the
device to report an alarm condition. System Sensor is not
responsible for devices that have been improperly installed,
tested, or maintained.
Installation
WARNING
High voltage. Electrocution Hazard. Do not handle live AC
wiring or work on a device to which AC power is applied.
Doing so may result in severe injury or death.
Operational Testing
Always notify a central station monitoring the system before repairing, maintaining, or testing alarm devices.
Upon completion of initial installation, all bells shall be
tested per NFPA 72. Periodic testing should be performed at
least annually. Test more often if required by the authority
having jurisdiction. Under normal conditions, System Sensor bells should provide years of trouble-free service; however, after extended service, parts of the bell may become
worn. In this case, bell should be replaced.
Do not repair or replace any bell components in the
field. If bell does not perform properly, replace the entire
unit. Failure to follow this instruction may result in failure of the bell to report an alarm condition.
1. Remove the gong.
2. Wire the bell in the circuit. See Figure 1, page 3.
3. Mount the bell mechanism on a 4˝ square electrical box
with the striker facing down. See Figures 2–4, page 3.
4. Replace the gong.
5. The top of the bell must be mounted a minimum of 90˝
above the floor, or within 6˝ of the ceiling.
CAUTION
Do not loop wire under terminals. Break wire runs to provide supervision of connections.
Audibility Rating Measurement
Sound level measurements are made in accordance with UL
Standard 464. The sound power output is measured in a reverberant room.

WARNING
The Limitations of Alarm Devices
System Sensor bells are designed to provide fire and security hazard
warning.
Bells may not work or operate properly if sprinkler piping being monitored
for water flow is plugged with pipe scale, mud, stones, or other foreign
material. Sprinkler systems should be checked regularly for such blocking
material following the instructions in Chapter 10 of NFPA 25.
BELLS WILL NOT WORK WITHOUT POWER. Bells get their power from
the fire or security panel monitoring the alarm system or AC circuit. If
power is cut for any reason, the device will not provide the desired audible
warning.
Alarms generated by the activation of waterflow detectors or supervisory
switches may not be received by a central station if telephone or other
communication lines to the detector are out of service, disabled, or open.
Three-Year Limited Warranty
System Sensor warrants its enclosed SSM or SSV bell to be free from defects in materials and workmanship under normal use and service for a
period of three years from date of manufacture. System Sensor makes no
other express warranty for this SSM or SSV bell. No agent, representative,
dealer, or employee of the Company has the authority to increase or alter
the obligations or limitations of this Warranty. The Company’s obligation
of this Warranty shall be limited to the repair or replacement of any part of
the SSM or SSV bell which is found to be defective in materials or workmanship under normal use and service during the three year period commencing with the date of manufacture. After phoning System Sensor’s toll
free number 800-SENSOR2 (736-7672) for a Return Authorization number,
send defective units postage prepaid to: System Sensor, Repair Depart-
BELLS MAY NOT BE HEARD. The loudness of the alarm device meets or
exceeds current Underwriters Laboratories’ standards. However, the bell
may not alert a sound sleeper or one who has recently used drugs or has
been drinking alcoholic beverages. The bell may not be heard on a different floor from the person in hazard or if placed too far away to be heard
over the ambient noise such as traffic, air conditioners, machinery, or music appliances that may prevent alert persons from hearing the alarm. THE
BELL MAY NOT BE HEARD BY PERSONS WHO ARE HEARING IMPAIRED.
If valves controlling the water supply to a sprinkler system are closed,
vane-type waterflow detectors will not work and bells will not sound. All
valves controlling a sprinkler water supply should be sealed or locked in
the normally open position. The normally open position of the valve
should be monitored by a valve supervisory switch.
ment, RA #__________, 3825 Ohio Avenue, St. Charles, IL 60174. Please
include a note describing the malfunction and suspected cause of failure.
The Company shall not be obligated to repair or replace units which are
found to be defective because of damage, unreasonable use, modifications, or alterations occurring after the date of manufacture. In no case
shall the Company be liable for any consequential or incidental damages
for breach of this or any other Warranty, expressed or implied whatsoever,
even if the loss or damage is caused by the Company’s negligence or fault.
Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to
you. This Warranty gives you specific legal rights, and you may also have
other rights which vary from state to state.
