another level or floor of a building. A second floor detector, for example, may not sense a first floor or
basement fire.
Furthermore, all types of smoke detectors, both ionization and photoelectric types, have sensing limitations. No
type of smoke detector can sense every kind of fire caused by carelessness and safety hazards such as smoking
in bed, violent explosions, escaping gas, improper storage of flammable materials, overloaded electrical circuits,
children playing with matches, or arson.
Notification appliances, such as bells, may not alert people if these appliances are located on the other side
of closed or partly open doors or are located on another floor of a building.
A fire alarm system will not operate without electrical power. If AC power fails, the system will operate from
standby batteries only for a specified time.
Rate-of-Rise heat detectors may be subject to reduced sensitivity over time. For this reason, the rate-of-
rise feature of each detector should be tested by a qualified fire protection specialist as recommended in
NFPA 72, Chapter 10.
Auxiliary Equipment used in the system may not be technically compatible with the control unit. It is
essential to use only equipment listed for service with your control unit.
Telephone lines needed to transmit alarm signals from a premise to a central monitoring station may be
out of service or temporarily disabled.
The most common cause of fire alarm malfunctions, however, is inadequate maintenance. All devices and
system wiring should be tested and maintained by professional fire alarm installers following written
procedures supplied with each device. System inspection and testing should be scheduled monthly or as
required by national and/or local fire codes. Adequate written records of all inspections should be kept.
