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

installing.
CAUTION
Do not use in potentially explosive atmospheres.
Do not leave any unused wires exposed.

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.
