Wiring Instructions:
The beacon is terminated with a 12" long 6-wire cable harness that may be connected as follows:
COLOR FUNCTION CONNECT TO
Red Power +VDC
Black Ground Chassis ground
White Pattern switching Chassis ground to activate
Yellow
Green
Violet
Synchronization
Failure mode detect
Dim
See synchronization below
See failure mode detect below
+VDC to activate
Operation:
Synchronization:
To synchronize multiple beacons, configure 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
activated, 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:
This feature activates when +VDC is connected to the beacon. 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:
- 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)
