The Gentex GEH12 Low‑frequency Horns offer a
dependable audible alarm and a low current draw.
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 volumes
with a peak sound of 100 dBA or greater at 10 ft
(3 m). They offer a choice between a 2400 Hz (remote
signaling) tone or a broadband low frequency
(1500 Hz to 3000 Hz) mechanical sounding
(evacuation) tone where closed doors could be a
problem. The user can also select either continuous or
temporal Code 3 tone output, and synchronize the
temporal signals by using the AVS Series
Synchronization Modules or a compatible control
panel.

Mounting Considerations
Outdoor Applications
For an outdoor application or a severe environment
(NEMA 3R) application, the GEH12 Series Horns must
be surface mounted on a flat wall in a GOE Outdoor
Enclosure. Use a watertight conduit fitting.
Indoor Applications
Install the horns with their tops at least 90 in. (2.3 m)
above the floor and no closer than 6 in. (15.2 cm) to
the ceiling. The horns are equipped with a four-inch
square mounting plate that can be attached as follows:

Shipping Information
The horns are delivered from the factory set to the
temporal lower frequency mode. Also included is a
locking mechanism that secures the product to the
bracket without any screws showing.
Wiring
The input terminals accept wires with diameters
between 18 AWG and 12 AWG (ISO 0.75 mm2 and
4 mm2).

Technical specifications
Electrical
Voltage Range:
8 VDC to 17.5 VDC
Voltage (Input):
12 VDC nominal
* If you operate the horn in this mode at this voltage, it
does not meet the UL reverberant sound level required
for public mode fire protection service. These settings
are acceptable only for private mode fire alarm use.
Use the high output setting for public mode
application.
Notice
Environmental
Relative Humidity
Up to 93% non‑condensing
Temperature (Operating):
+32°F to +120°F (0°C to +49°C)
The sound output for the temporal (Code 3) tone
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.
