u Use the SuperSlide feature for easy testing
u Wide voltage range; 16 to 33 VDC or FWR
The Gentex Commander3 24 V Low‑frequency Strobes
(GES3‑24) and Horn Strobe (GEC3‑24) combinations
offer dependable alarms, a low current draw, and a
minimum flash rate of 1 Hz regardless of input voltage.
Functions
Easy Installation and Testing
The user can wire then install the entire system,
reducing installation and operating costs. Use the
SuperSlide feature to test supervision.
Horn Output
The horns provide a selection of high or low dBA. They
produce a peak sound of 100 dBA or greater at 10 ft
(3 m).
The horn offers a choice between a 2400 Hz (remote
signaling) tone or a low frequency mechanical
sounding (evacuation) tone where closed doors could
prevent hearing the other tone. The user can also
select either continuous or temporal Code 3 tone
output, and synchronize the temporal signal by using
an AVS Series Synchronization Module.
Strobe Output
Select from 15 cd, 30 cd, 60 cd, 75 cd, or 110 cd while
in the field using a sliding switch. The horn strobe

and temporal Code 3 or continuous tone pattern
control panel can silence the audible signal while
leaving the visible signal energized with the use of a
single pair of power wires.

The D7022 must be set for 24 VDC operation and
requires the AVS44 or AVSM Synchronization Modules
for synchronization.

When used with a D7039 Multiplex Expansion
Module, the FPD-7024 and D7024 become
addressable FACPs.

For synchronization, use the AVS44 or AVSM
Synchronization Modules with these control panels.
Mounting Considerations
Notice
Use the GE3‑24 horns and horn strobes for indoor
installations only.
These strobes and horn strobe combinations are
equipped with a four‑inch square metal mounting plate
that can be attached as follows:
