u Silence the horn while strobes flash

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
appliance with the AVS44, AVSM, or a compatible

u Many candela choices

u Select high or low frequency, high or low volume,

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:

Also included is a locking mechanism that secures the
product to the bracket without any screws showing.

Shipping Information

The GEC3‑24 horn strobe models are delivered from
the factory set to the temporal lower frequency mode.

Wiring

The input terminals accept wires with diameters
between 18 AWG and 12 AWG (ISO 0.75 mm2 and

Notice

is rated lower because the time the horn is off is
averaged into the sound output rating. When the
horn is producing a tone in the Temporal mode its
sound pressure is the same as the Continuous
mode.
