Product Overview Lower current draw Available in 15, 15/75, 30, 75, 95, 115, and 177 candela Horn/strobe models include a three position switch for field-selecting horn tones: - Electromechanical/3KHz - Temporal/Non-temporal - High/Low dBA output Ceiling-specific shape, profile, and aesthetics Synchronizable with MDL Sync*CircuitTM module Mounts to 4x 4x 11 2 back box Round shape offers greater placement flexibility System Sensor's SpectrAlert(R) ceiling mount series strobes and horn/strobes offer a fresh approach to addressing the unique needs for ceiling mount applications. Technology. Like the original SpectrAlert, the SpectrAlert ceiling mount series
offer significant current draw reductions over other ceiling mount strobes and horn/strobes.
Installation. SpectrAlert's compact design also offers installation savings. The
strobe and horn/strobe models mount to a 4x4x112 back box, and take up little room in the back box, making connections easier. And with SpectrAlert's round shape, it is not necessary to align the back box with the room's walls. SpectrAlert always lines up.
Flexibility. SpectrAlert ceiling mount strobes and horn/strobes are available in
seven different candelas, including 177 candela for sleeping areas. The horn/ strobe's tones are field-selectable through the use of a three position switch located on the back of the unit. Selections include electromechanical and 3 KHz tones, temporal and non-temporal patterns, and high and low volume.
Aesthetics. SpectrAlert ceiling strobes and horn/strobes offer a design that is sensi-
tive to the aesthetic demands of ceiling mount applications. The round shape maintains a low profile appearance, similar to that of a smoke detector and provides clearly visible "FIRE" identification from all angles.

Engineering Specifications Strobe
Strobe shall be a System Sensor SpectrAlert Model _________ listed to UL 1971 and be approved for fire protective service where ceiling mount strobes are permitted. The strobe shall be wired as a primary signaling notification appliance and shall flash at 1Hz over the strobe's entire operating range. The strobe light shall consist 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 be approved for fire protective service where ceiling mount horn/strobes are permitted. The horn/strobe shall be wired as a primary signaling notification appliance and shall flash at 1Hz over its entire operating 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, and the option to switch between a temporal and a non-temporal continuous pattern. These options shall be selected by a multi-position switch. 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. Note: The strobes must be powered continuously for the horn to operate.

Explanation of Published Voltage, Current, and SPL Specifications
In May 2004 Underwriters Laboratories changed standard UL 1971 to require that operating current measuremments are made using RMS (root mean square) instead of peak or average values. RMS measurements more accurately predict the power consumption of a device since they take into account the entire current draw profile including surge, repetitive surge, and peak values. The published RMS current is the maximum operating current of that device within its operating voltage range. This current maximum may or may not occur at the endpoints of the voltage range.
During May 2004, UL also changed the way they list the voltage range of a device. All 12V products will be listed between 8 - 17.5V and all 24V products will be listed between 16 - 33V. Those devices are considered "regulated". Any product that does not operate within these ranges will be listed as a "special application" with its operating voltage specified on the device.
