Engineering Specifications
General
SpectrAlert horns, strobes and horn/strobes shall be capable of
mounting to a standard 4˝ × 4˝ × 1¹/2˝ back box or a single gang
2˝ × 4˝ × 1⁷/8˝ back box using the universal mounting plate
included with each SpectrAlert product. Also, SpectrAlert prod-
ucts, when used in conjunction with the accessory Sync•Circuit
Module, shall be powered 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 9–17.5 volts. 24-volt rated
devices shall have an operating voltage range or 17–33 volts.
SpectrAlert products shall have an operating temperature of
32° to 120°F and operate from a regulated DC or full wave
rectified, unfiltered power supply.
Strobe
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 require-
ments for visible signaling appliances, flashing at 1Hz over the
strobe’s entire operating voltage range. The strobe light shall con-
sist of a xenon flash tube and associated lens/reflector system.
Horn/Strobe Combination
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 sup-
ply (the strobe must be powered continuously).
Synchronization Module
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 4¹¹/16˝ ×
4¹¹/16˝ × 2¹/8˝ back box and shall control two Style Y (class B) or
one Style Z (class A) circuit. Module shall be capable of multiple
zone 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.

Notes:
1. Full Wave Rectified (FWR) voltage is a non-regulated, time-var ying power source that is used on some power supply and panel outputs.
2. The MDL causes a one-volt voltage drop in the notification appliance circuit.
