MANUAL FIRE ALARM EVACUATION SYSTEMS
(Refer to NAVFAC Guide Specification NFCS-16722 for further details)
GENERAL DESCRIPTION: A manual fire alarm evacuation system consists of
a method for alerting occupants of a building in the event of fire or
other emergency. Operation of a manual fire-alarm system is
accomplished by manually actuating a fire alarm pull station which in
turn automatically activates an alarm system of horns throughout the
building. Where station exterior fire alarm systems exist or where it
is feasible, the alarm is also automatically transmitted to fire alarm
headquarters. Pull stations and horns are normally located at points
of egress from building.
