Fire Alarm Verification for Smoke Detectors

This feature applies to 2-wire smoke detectors wired to zone 5 when zone 5 is set

to response type 16. This feature also applies to 4-wire smoke detectors wired to

any zone when the zone is set to response type 16 and the detectors are powered

from the Aux relay power output (field *34 must be set to 2).

The control will verify any alarm by resetting the smoke detectors after the first

alarm trigger and then waiting 90 seconds for a second alarm trigger. If the

smoke detector does not trigger again, the control will disregard the first trigger

and no alarm signal will occur. This feature eliminates false alarms due to

electrical or physical transients.

Turning Off Fire Alarm Sounding

You can turn off Fire alarm sounding by pressing the Silence/Reset key on the

control's pc board or by entering the user's code + OFF [1] key on any keypad. To

clear the "Alarm Silenced" message and to reset the detector's alarm, press the

Silence/Reset key or enter the User's Code + OFF again.
