Description
SpectrAlert® Ceiling Mount Series
Strobes and Horn/Strobes
from
System Sensor offer a fresh approach
to the unique needs of ceiling-mount
applications.
Technology
— Like the original
SpectrAlert® line, the SpectrAlert®
Ceiling Mount Series offers significant
current draw reductions over other
ceiling-mount strobes and horn/
strobes.

PC Horn/Strobe (bottom)
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 with a three-position
switch on the back of the unit.
Selections include: electromechanical
and 3 KHz tones; temporal 3 and non-
temporal 3 patterns; and high and low
volume.

Aesthetics
— SpectrAlert® Ceiling Mount strobes and horn/strobes offer a
design that is sensitive to the aesthetic demands of ceiling-mount applications.
The round shape maintains a low-profile appearance, similar to that of a smoke
detector. Its stylish curves and design further refine the aesthetics over other
generic wall/ceiling-mount designs. Yet SpectrAlert®’s round shape provides
clearly visible “FIRE” identification from all angles.
Installation
— SpectrAlert®’s compact design also offers installation savings.
The strobe and horn/strobe models mount to a 4" x 4" x 1.5" (101.6 x 101.6 x
38.1 mm) backbox, and take up little room in the backbox, making connections
easier. With SpectrAlert®’s round shape, aligning the backbox with the room’s
walls is not necessary — SpectrAlert® always lines up.
