FIRE ALARM SYSTEMS
Description
WHEELOCK’S Series AMT Multiple Input Electronic
Appliances provide the industry with a ULC combination
audible/visual appliance that simplifies installation and
offers three (3) distinct prioritized audible signals from
three isolated inputs. Priority (1) will override all other
commands upon activation.
The AMT offers a choice of eight (8) self-prioritized sound
combinations for suppression releasing systems,
combination security and emergency evacuation
systems and high risk installations as well as many
other applications.
Each AMT Audible and AMT S trobe appliance has two
user selective sound output levels: Standard dBA and
High dBA. The AMT Audible provides 12VDC or 24VDC
operation, filtered or FWR. The AMT S trobe Appliances
operate at 24VDC and may be used with filtered or
unfiltered (FWR) input voltages. Separate supervised
sets of input terminals are available for each prioritized
input. Jumper plugs are provided to enable both tone
and strobe to operate simultaneously for all inputs.
The AMT Multitone S trobe Appliances are ULC Listed
under Standard CAN/ULC-S526-02 for V isual Signaling
Appliances and Standard CAN/ULC-S525-99 for Audible
Signaling Appliances and use a Xenon flashtube with
solid state circuitry enclosed in a rugged Lexan® lens
to provide maximum reliability for effective visible
signaling.
All models may be synchronized when used in
conjunction with the Wheelock SM or DSM Sync
Modules, with patented Sync Protocol.
Synchronization of the continuous horn tone provides
the temporal (Code 3) tone as mandated by NFP A-72
for all audible appliances. 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 ADA
recommendations concerning photosensitive epilepsy
and NFPA and UFC standards when installing tow or
more visual appliances within the field of view.

Add average strobe current from Table 4 to average audible current
from Table 1 to obtain total average current for each unit, if the strobe
and audible are wired to operate in unison on a single circuit.
Wheelock’s AMT Appliances are unique multitone alarm signals with
separate input terminals for each sound. They are the ideal choice for
suppression systems and emergency signaling systems where
distinctive multiple alarm conditions are required. Eight groups of
three self-prioritized sound outputs are provided with separate electrically isolated input terminals for each sound (see Table 2 and Table
5 for sound selections). Sound output can be field set to provide either
HIGH (HI) dBA or STANDARD (STD) dBA sound output level.
All AMT Multitone Strobe models are designed for use with either
filtered or unfiltered Full-Wave-Rectified (FWR) input voltage. The AMT
Multitone Strobe Appliances have separate input terminals for alarm
tone activation and strobe activation. The strobes can be easily field
programmed to operate independently or in unison with all of the
audible alarms. All inputs are polarized for compatibility with standard
reverse polarity supervision of circuit wiring by a Fire Alarm Control
Panel (FACP). In the event that three simultaneous commands occur,
priority one will activate. If priority 2 + priority 3 exist, priority 2 will
activate.
