Quiet Alarm
Quiet alarm is an alarm type that can be programmed via EBLWin for analogue smoke
detectors. The quiet alarm is self-resetting alarm (non-latching), it is only displayed on the
LCD and is not activating any general alarm functions.
This feature is used in AS1668 supply air fan / stair pressurization fan control applications
or in residential units as a non-latching smoke detector alarm.
In AS1668 supply air fan applications, the type "Quiet alarm" is used to set in EBLWin the
duct detector to be non-latching and resets automatically after the post timing
completed, post time can be configured in EBLWin using a specific time signal period. The
I/O module 4461 must be selected as "4461 for fan".
In residential applications, an analogue smoke detector set to type "Quiet alarm" is used in
conjunction with the sounder base 3379 and LAAU 4445 (or ADF) as a local warning inside
the sole occupancy unit.
