u Field‑selectable candela options (15 cd, 30 cd,
75 cd, 95 cd, and 115 cd)
The Commander4 Series Ceiling‑mount Strobes and
Horn Strobe combinations offer dependable audible
and visual alarms, low current draw, and a minimum
flash rate of 1 Hz regardless of the input voltage.
These models offer field‑selectable options of 15 cd,
30 cd, 75 cd, 95 cd, 115 cd, and 150 cd.
The horns provide a selection of high or low dBA and a
selection of 2400 Hz (remote signaling) or a low
frequency broad band from 1500 Hz to 3000 Hz
mechanical sounding (evacuation) tone where doors
could be a problem. These models are easily
field‑changeable from Temporal Code 3 to a
continuous tone.
These devices come standard with a 4 in. (10.2 cm)
mounting plate, and incorporate the popular
SuperSlide feature that allows you to easily test for
supervision.
Certifications and approvals
Gentex Corporation holds these Listings and
Approvals:
u Separate horn and strobe functions; silence horn
while strobes remain flashing
u Strobe, horn, or both can be synchronized using the
AVS Series Synchronization Modules
u Silence horn while strobes remain flashing
u Switch selection for high or low dBA, high or low
frequency, and for Temporal Code 3, Chime, or
Whoop tones

Notice
The sound output for the temporal (Code 3) mode
is rated lower because the time that the horn is
off is averaged into the sound output rating. While
the horn is producing a tone in Temporal mode,
its sound pressure is the same as the Continuous
mode.
