• 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.
• 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 premises to a central
monitoring station may be out of service or temporarily disabled.
• The most common cause of fire alarm malfunctions 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 and standards. Adequate
written records of all inspections should be kept.
