The Local Alarm Acknowledgement Unit (4445) is the newer version of the

Quiet Alarm
Quiet alarm is an alarm type that can be programmed via EBLWin for an analogue smoke
detector. The quiet alarm is self-resetting alarm (non-latching), it is only displayed on the
LCD and does not activate any general alarm functions.
This feature is used in AS1668 supply air / stair pressurization fan control applications or
in residential units as a non-latching smoke alarm.
In AS1668 supply air fan applications, the type “Quiet alarm” is used to set the duct
detector to be non-latching and resets automatically after the post timing
this can be configured in EBLWin.
A smoke detector (in duct probe) set in EBLWin to “Quiet alarm” is normally used in
conjunction AS1668 fan control module, it requires an I/O unit 3361 selected in EBLWin
as “3361 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.
