AS Audible
Strobe
• Patented Universal Mounting
Plate
The audible provides a selectable choice of either
a continous 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.
• Weatherproof models are
available for outdoor use
• Strobes produce 1 flash per
second over the regulated voltage
range
When used with the Wheelock Series SM or DSM
Sync Module or with a power supply with the
Wheelock sync protocol, synchronization of the
continous horn tone provides the temporal (code 3)
tone (mandated by NFPA 72) simultaneously for all
audible appliances. This ensurses a distinct tem-
poral (code 3) pattern when 2 or more audibles are
within hearing distance. If not synchronized the tem-
poral sound could overlap and not be distinctive. At
the same time the strobes will be synchronized.
This provides the ability to comply with ADA guide-
• 12 and 24 VDC models with wide
UL “Regulated Voltage Range”
using filtered DC or unfiltered
FWR input voltage
• Synchronize with Wheelock SM,
DSM or power supply with built-
in Wheelock sync protocol
• Fast installation with IN/OUT
screw terminals using #12 and
#18 AWG wires
AH Audible
lines concerning photosensitive epilepsy and the NFPA standards when install-
ing 2 or more visual appliances within the field of view all of this plus the ability to
silence the audible is achieved using only 2 wire.
