feature for easy testing
The Gentex low‑profile strobe (GES3‑12WR) and horn
strobe (GEC3‑12WR) offer dependable alarms, a low
current draw, an 8 VDC to 17.5 VDC voltage range, 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 volume.
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.
Strobe Output
Select from 15 cd, 30 cd, 60 cd, or 75 cd while in the
field using a sliding switch. The horn strobe appliance,
with the AVS‑44, AVSM or a compatible control panel,
can silence the audible signal while leaving the visible
signal energized with the use of a single pair of power
wires.
u Four candela choices: 15, 30, 60, or 75 cd
u Select high or low frequency, high or low volume,
and temporal Code 3 or continuous tone pattern

Shipping Information
The horn strobe models are delivered from the factory
set to the temporal lower frequency mode.
Wiring
Notice
Do not use these units in coded or pulsed

Alarm Ratings
Notice
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.
