IV. WIRING
Wiring for synchronized strobes and horns.
Using this method you may:
Use only two wires to synchronize the temporal horn and strobe with the ability to mute the horn (place
switches 1 and 2 in the ON position on the GEC24, GEC3-24, GEC3-12, WGEC24, GECA24, GECB24,
GECG24, GECR24, WGECA24, WGECB24, WGECG24, WGECR24).
Mute the horn only when the temporal horn option has been selected.
Use the Gentex synchronization protocol to provide synchronization and mute the horn, if available.
Wiring for synchronized parallel (unison) horn/strobe operation.
Using this method you may:
Use four wires where two wires are used to power and synchronize the strobe and two additional wires
are used to power and synchronize the horn (place switches 1 and 2 in the OFF position on the GEC24,
GEC3-24, GEC3-12, WGEC24, GECA24, GECB24, GECG24, GECR24, WGECA24, WGECB24,
WGECG24, WGECR24).
Choose either continuous horn and allow the FACP to control the horn or choose temporal horn and synchronize the horns with the Gentex synchronization protocol.
Use the Gentex synchronization protocol to provide synchronization and mute the horn, if available.
NOTICE:
FOR THIS OPTION, SWITCHES 1 AND 2 ON THE GEC24, GEC3-24, GEC3-12, WGEC24, GECA24, GECB24, GECG24, GECR24, WGECA24, WGECB24, WGEC24, WGECR24 MUST
BE IN THE OFF POSITION TO ISOLATE POWER TO THE AUDIBLE AND VISIBLE PORTION OF THE CIRCUIT.
ALL STROBES ARE DESIGNED TO FLASH AS SPECIFIED WITH CONTINUOUS APPLIED VOLTAGE. THIS APPLIANCE IS NOT RECOMMENDED FOR USE ON CODED OR PULSING
SIGNALING CIRCUITS. HOWEVER, USE OF THE AVSM CONTROL MODULE IS PERMITTED TO SYNCHRONIZE THE STROBE AND/OR MUTE THE HORN.
REFERENCE AVSM CONTROL MODULE MANUAL (550-0284, DATED 2-1-03) FOR SYNCHRONIZATION MODULE WIRING DIAGRAMS. AVSM MANUAL CAN BE OBTAINED AT
HTTP://WWW.GENTEX.COM OR CALL GENTEX CORPORATION AT 1-800-436-8391.
Conventional Method:
You may connect both the strobe and the horn directly from a source of rated power without the use of a control module. However, the horns and strobe lights will NOT be synchronized. Place
switches 1 and 2 in the ON position on the GEC24, GEC3-24, GEC3-12, WGEC24, GECA24, GECB24, GECG24, GECR24, WGECA24, WGECB24, WGECG24, WGECR24 to power both the
audible and visible from a single pair of power wires. If you wish to power the horn and strobe from independent sources of power, place switches 1 and 2 in the OFF position on the GEC24,
GEC3-24, GEC3-12, WGEC24, GECA24, GECB24, GECG24, GECR24, WGECA24, WGECB24, WGECG24, WGECR24 and connect power to the appropriate terminals.
CAUTION: When using only a single power source to
energize the strobe and horn (switches 1 and 2 in the ON
position), the in/out wiring must be under the S+ and S-
terminals only. Failure to do so may result in damage to your
signal. For the horn only (GEH24 and GEH12) and strobe only
(GES24, GES3-24, GES3-12, WGES24, GESA24, GESB24,
GESG24, GESR24, WGESA24, WGESB24, WGESG24,
WGESR24), only the top three terminals are to be used.

NOTICE:
SWITCH POSITIONS 1 AND 2 IN THE OFF POSITION TO
SELECT ISOLATED HORN AND STROBE POWER INPUTS
SWITCH POSITION 6 ON = HIGH DBA
SWITCH POSITION 6 OFF = LOW DBA
CAUTION: A jumper card is provided to test for correct
wiring in the supervisory mode only. DO NOT pass alarm
current through the jumper.
Gentex Super-Slide ® Mounting Bracket:
Allows the installer to pre-wire the system, test for system
supervision, remove the signal head until occupancy,
switch out Gentex signals without changing mounting
brackets and has locking edge connector for snap-in-place
installation.
Gentex Checkmate ® Instant Voltage Verification:
It is often necessary to confirm the voltage drop along a
line of devices. The access holes are provided in the back
of the terminal block to allow the voltage to be measured
directly without removing the device. Typically this would
be done at the end of the line to confirm design criteria.
Most measurements will be taken using the S+ and S-
locations although access is provided to other locations.
NOTICE: CARE SHOULD BE TAKEN TO NOT SHORT
THE TEST PROBES.
