Wiring Instructions:
The beacon is terminated with a 12" long 6-wire cable harness that may be connected as follows:

+VDC to activate
Operation:
Beacon Warning Signal:
This feature activates when +VDC is connected to the RED wire and the BLACK wire is connected to ground. The
flash pattern may be changed as noted below.
Synchronization:
Multiple beacons may be synchronized if configured as noted below. A maximum of 8 lights may be synchronized.
- To configure the beacons to flash their patterns simultaneously, advance the pattern for each beacon to Phase 0
mode of the chosen pattern. Connect the YELLOW wires from each beacon together. When the beacons are acti-
vated, their patterns will flash together.
- To configure the beacons to alternate their patterns, advance the pattern of either beacon (but not both) to the
Phase 1 mode of the chosen pattern.
Failure Mode Detect:
When +VDC is connected to the RED wire (warning signal activated), the following conditions are checked:
- Input voltage is at an adequate level to fully operate the beacon.
- The beacon's micro-processor is operating.
When the above are satisfied, the green wire is switched to ground and will support a current load up to 250 milli-
amps. The green wire may serve to control an Indicator Light connected to +VDC that activates when the beacon is
ON and is functioning. The indicator light is not provided with the beacon.
Setting the Flash Pattern:
Momentarily connect the WHITE wire to chassis ground as follows (beacon ON - warning signal must be activated):
- For the NEXT pattern;
release contact when beacon flashes ON (less than 2 seconds)
- For the PREVIOUS pattern; release contact when beacon flashes ON then OFF (2 to 4 seconds)
- For the DEFAULT pattern;
release contact when beacon flashes ON then OFF then ON again (greater
than 4 seconds)
Task light:
This feature activates when +VDC is connected to the WHITE wire (with BLACK connected to ground) and may be
operated alone or in conjunction with the beacon's flashing color signal on the opposite side of the beacon. The task
light can not be operated as a flashing signal.
