Architect/Engineer Specifications
General
The L-Series ceiling-mount strobes and horn strobes shall
mount to any of the following:
• double-gang backbox
• 4-inch octagon backbox
• a standard 4 x 4 x 1 1/2-inch backbox
Two-wire products shall also mount to a single-gang compact 2
x 4 x 17/8-inch backbox. A universal mounting plate shall be
used for mounting ceiling and wall products. The notification
appliance circuit wiring shall terminate at the universal
mounting plate.
Also, the L-Series products, when used with the Sync•Circuit
Module accessory, shall be powered from a non-coded
notification appliance circuit output and shall operate on a
nominal 12 or 24 volts. When it is used with the Sync•Circuit
Module, the following occur:
• 12-volt-rated notification appliance circuit outputs shall
operate between 8.5 and 17.5 volts.
• 24-volt-rated notification appliance circuit outputs shall
operate between 16.5 and 33 volts.
The Indoor L-Series products shall operate between 32 and
120 degrees Fahrenheit from a regulated DC or full-wave
rectified unfiltered power supply.
Ceiling strobes and horn strobes shall have the following field-
selectable candela settings including:
• 15
• 30
• 115
• 150
Strobe
The strobe shall be an L-Series Model _______ listed to UL
Standard 1971 and shall 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 appliances, flashing at 1 Hz
over the strobe's entire operating voltage range. The strobe light
shall consist of a xenon flash tube and associated lens/
reflector system.
Horn Strobe Combination
The horn strobe shall be an L-Series Model _______ listed to UL
Standard 1971 and UL Standard 464 and shall be approved for
fire protective service. The 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 1 Hz 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 audibility options and an option to switch
between a temporal three pattern and a non-temporal
(continuous) pattern. These options are set by a multiple
position switch. The horn on horn strobe models shall operate o
a coded or non-coded power supply.

Synchronization Module
The module shall be a Sync•Circuit model MDL3 listed to UL
Standard 464 and shall be approved for fire protective service.
The module shall synchronize the L-Series strobes at 1 Hz and
synchronize horns at temporal three. Also, while operating the
strobes, the module shall silence the horns on horn strobe
models over a single-pair of wires.
The module shall mount to a 4 11/6 x 4 11/16 x 2 1/8-inch
backbox. The module shall also control two Style Y (Class B)
circuits or one Style Z (Class A) circuit. The module shall
synchronize multiple zones. Daisy-chaining two or more
synchronization modules together will synchronize all the
zones they control. The module shall not operate on a coded
power supply.
