Description of System Operation
The delayed egress alarm becomes activated when
the push bar of the Series 1500 modified exit device is
depressed. A concealed AE (request-to-exit) switch initiates
an irreversible cycle that begins with the Series 1300
audible alarm sounding for a predetermined time (field
adjustable) while the Series 3700 electromagnetic lock
remains energized locking the door.
At the end of the timing cycle, the electromagnetic lock
de-energizes and unlocks the door while the audible alarm
continues sounding. The door will remain unlocked and
in an alarm state until manually reset by the Series 1300
keyswitch. Resetting the system will lock the door by
energizing the electromagnetic lock and will turn off the
audible alarm.
When using the system with a door position switch,
the door must be fully closed prior to resetting the
system. Resetting with the door open will energize the
electromagnetic lock, but will not turn off the audible alarm.
The audible alarm will also begin sounding if a forced entry
occurs while the system is armed.
In the event of a fire alarm, the electromagnetic lock will
immediately de-energize to unlock the door. Upon resetting
the fire alarm, the system will return to normal standby
operation.
