System Sensor SSM and SSV Models - Manual (Page 2)

D770-11-00 2 I56-0674-008R
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.
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 pro-
vide 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.
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 author-
ity 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.
