The audible provides a selectable choice of either a
continuous horn or temporal pattern (Code 3) when
constant voltage from a Fire Alarm Panel (FACP) is
applied. Each tone has 3 dBA settings to choose from.
Additionally , the audible may be silenced while
maintaining strobe activation on combination
Series AS units.

All models may be synchronized when used in
conjunction with the Wheelock SM or DSM Sync
Module(s).

Synchronization of the continuous horn tone provides the
temporal (Code 3) tone. This ensures a distinct temporal
(Code 3) pattern when 2 or more audibles are within hearing
distance. If not synchronized, the temporal sound may
overlap and not be distinctive. At the same time, the
strobes will also be synchronized. This provides the ability
to comply with recommendations concerning
photosensitive epilepsy and when installing two or more
visual appliances within the field of view.

All of this, plus the ability to silence the audible is
achieved by using only 2 WIRES.

Wheelock’s Series AS Audible Strobes and AH Audibles
employ a Patented Universal Mounting Plate that can be
mounted to single gang, double gang, 4 “ square, 100mm
European back boxes or the SHBB surface back box.

For Weatherproof Series AS Audible Strobe,
