CAUTION: A jumper card is provided to test for correct wiring in the supervisory mode only. DO NOT pass alarm current through the jumper.

NOTE: 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.

IV. WIRING

Wiring for independent synchronized strobes and horn.

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 up on the GEC3-12).

· Mute the horn only when the temporal horn option has been selected.

Wiring for synchronized parallel (unison) horn/strobe operation.

Using this method you may:

· Use only two wires to synchronize the temporal horn and strobe without the ability to mute the horn (place switches 1 and 2 up on the GEC3-12).

· Choose either temporal or continuous horn with the temporal horn synchronized.

· Also wire the control module (AVSM) to only the strobe input power terminals, set the horn to continuous mode and power it from a coded source.

NOTE: For this option, switches 1 and 2 on the GEC3-12 (Fig.1) must be down to isolate power to the audible and visible portion of the circuit.

Checkmate

Voltage Verification

Access Holes:

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.

NOTE: Care should be taken to not short

the test probes.
