System Sensor’s SpectrAlert
®
wall-mount series includes a complete line of electronic
horns, strobes, and horn/strobes. Intended for primary signaling use, SpectrAlert
products meet UL1971, UL464, and Americans with Disabilities Act requirements.
Technology.
With its extremely efficient reflector design and Xenon flash tube,
SpectrAlert offers current draw reductions as high as 40% over previous gener-
ation designs. By consuming less current, the flexibility to connect more devices
per loop is possible, for a lower installed cost.
Installation.
SpectrAlert products offer installation ease which also lowers the
installed cost. By taking up no room in the back box, SpectrAlert strobes and
horn/strobes make wiring connections simpler and faster. Each SpectrAlert
includes a universal mounting plate for 4″ square and single gang back box
mounting. Accessory mounting plates are also available for small footprint or
surface mount applications.
Flexibility.
SpectrAlert offers the flexibility to meet a broad range of
requirements. The SpectrAlert horns and horn/strobes feature a number of
field-selectable/reversible horn tones. For visible requirements, SpectrAlert
strobes and horn/strobes are available in a wide variety of configurations to
address non-sleeping area, sleeping area, and corridor requirements.
Offerings include 24-volt models at 15, 15/75, 30, 75, and 110 candela,
and 12-volt devices at 15 and 15/75 candela.
Aesthetics.
To meet building owner aesthetic requirements, SpectrAlert
incorporates a stylish, low profile design. And this aesthetic is consistent across
all SpectrAlert wall-mount products.

Also, SpectrAlert products, when used in conjuction
with the accessory Sync
•
Circuit Module, shall be pow-
ered from a non-coded power supply and shall operate
on 12 or 24 volts. 12 volt rated devices shall have an
operating voltage range of 10.7–17 volts. 24-volt rated
devices shall have an operating voltage range or 20–30
volts. SpectrAlert products shall have an operating tem-
perature of 32° to 120°F and operate from a regulated
DC or full wave rectified, unfiltered power supply.
Horn
Horn shall be a System Sensor SpectrAlert Model
capable of operating at 12 and 24 volts. Horn shall be
listed to UL 464 for fire protective signaling systems. The
horn shall have two tone options, two audibility options
(at 24 volts) and the option to switch between a temporal
3 pattern and a non-temporal continuous pattern. All horn
models shall operate on a coded power supply.
Strobe
Horn/Strobe shall be a System Sensor SpectrAlert Model
listed to UL 1971 and UL 464 and shall be
approved for fire protective service. Horn/strobe shall
be wired as a primary signaling notification appliance
and comply with the Americans with Disabilities Act
requirements for visible signaling appliances, flashing at
1Hz over the strobe’s entire operating voltage range.
The strobe light shall consist of a xenon flash tube and
associated lens/reflector system. The horn shall have two
tone options, two audibility options (at 24 volts) and the
option to switch between a temporal 3 pattern and a
non-temporal continuous pattern. Strobes shall be powered
independently of the sounder with the removal of factory
installed jumper wires. The horn on horn/strobe models
shall operate on a coded or non-coded power supply
(the strobe must be powered continuously).
Synchronization Module
Strobe shall be a System Sensor SpectrAlert Model
listed to UL 1971 and be approved for fire protective
service. The strobe shall be wired as a primary signaling
notification appliance and comply with the Americans with
Disabilities Act requirements for visible signaling appli-
ances, flashing at 1Hz over the strobe’s entire operating
voltage range. The strobe light shall consist of a xenon
flash tube and associated lens/reflector system.
Module shall be a System Sensor Sync
•
Circuit
listed to UL 464 and shall be approved for fire protective
service. The module shall synchronize SpectrAlert strobes
at 1Hz and horns at temporal 3. Also, the module shall
silence the horns on horn/strobe models, while operating
the strobes, over a single pair of wires. The module shall
be capable of mounting to a 4

synchronization by daisy chaining multiple modules
together and re-synchronizing each other along the chain.
The module shall not operate on a coded power supply.
