LIMITATIONS OF ALARM DEVICES
System Sensor bells are designed to provide fire and security hazard warning.
1. Bells may not work or operate properly if sprinkler piping being monitored is plugged with pipe scale, mud, stones, or
other foreign material. Sprinkler systems should be checked regularly for such blocking material following the instruc-
tions in Chapter 5 of NFPA Standard 13A.
2. BELLS WILL NOT WORK WITHOUT POWER. Since the bell gets its power from the fire or security panel monitoring
the alarm system, if power is cut for any reason, the device will not provide the desired audible warning. Alarms gen-
erated by the activation of waterflow detectors may not be received by a central station if telephone or other commu-
nication lines to the detector are out of service, disabled, or open.
3. 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 sounding device 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 SOUNDER MAY NOT BE HEARD BY PERSONS WHO ARE
HEARING IMPAIRED.
4. Sprinkler systems and associated bells are not a substitute for insurance. Building owners should always insure prop-
erty and lives being protected by sprinkler systems.
5. 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 should be monitored by a sprinkler supervisory switch.
