2.2 Wiring the Beacon
The beacon is supplied with a 50-foot length of power & alarm cable pre-wired to the internal
electronics to facilitate installation (see Table 2-1). The only connections required are power
(120-240 VAC, 50/60 Hz) and ground. The ground wire must be connected for proper operation
and protection of the beacon.
Optional dry contact monitoring connections permit monitoring of beacon operation. The
contact is closed when the beacon is operating normally and no fault is detected.
The Auxiliary Control Input allows an external device, such as a radar system, to inhibit the
flashing of the beacon (see Table 2-2). The acceptable input voltage range for the Control Input
is 5 – 30 Volts AC/DC. The optional 10 conductor cable is required to utilize this feature.
