IV. WIRING
Wiring for synchronized strobes and horns.
Using this method you may:
w
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 GEC3-12).
w
Mute the horn
only
when the temporal horn option has been selected.
w
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:
w
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 GEC3-12).
w
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.
w
Use the Gentex synchronization protocol to provide synchronization and mute the horn, if available.
NOTICE:
w
FOR THIS OPTION, SWITCHES
1
AND
2
ON THE GEC3-12 MUST BE IN THE OFF POSITION TO ISOLATE POWER TO THE AUDIBLE AND VISIBLE PORTION OF THE
CIRCUIT.
w
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.
w
SEE AVSM CONTROL MODULE MANUAL (550-0284, MANUAL ISSUE DATE 2-1-03) FOR SYNCHRONIZATION MODULE WIRING DIAGRAMS. AVSM MANUAL CAN
BE OBTAINED AT HTTP://WWW.GENTEX.COM/FIRE/PRODUCTS 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 GEC3-12 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 GEC3-12 and connect power to the appropriate terminals.

NOTICE:

THE THREE PULSE TEMPORAL PATTERN IS TO BE USED FOR EVACUATION USE ONLY.
w
THE SOUND OUTPUT FOR THE TEMPORAL 3 TONE IS RATED LOWER SINCE THE TIME THE HORN IS OFF IS AVERAGED INTO THE SOUND
OUT PUT RATING. WHILE THE HORN IS PRODUCING A TONE IN THE TEMPORAL 3 MODE ITS SOUND PRESSURE IS THE SAME AS THE
CONTINUOUS MODE. UNITS HAVE BEEN TESTED TO 0°C, 49°C AND 93% HUMIDITY.
* Operating the horn in this mode at this voltage will result in not meeting the minimum ANSI/UL 464 sound level required for public mode
fire protection service. These settings are acceptable only for private mode fire alarm signaling use. Use the high dBA setting for public
mode applications (the chime tone is always private mode).

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 (GEH12) and strobe only
(GES3-12), only the top three terminals are to be used.
