In the event the beacon is purchased for use in conjunction with an Aircraft Detection Lighting System (ADLS)
radar, the beacon is supplied with a 10-conductor, pre-wired, power and alarm cable (see
, page 11). The
beacon is connected to a Light Controlling Module (LCM) like Flash Technology’s FTC 370 or similar radar interface
device. Refer to the LCM wiring diagram for information on connections.

2.4 VERIFYING OPERATION
Apply power to the beacon and verify operation.
2.4.1 POWER UP
When powered up, the beacon will begin flashing after several seconds. The beacon will continue to flash for 15
minutes. After the initial 15 minutes, the unit will stop flashing once the photodiode detects sufficient light for 30
seconds.
2.4.2 SYNCHRONIZATION
For synchronization to occur, the GPS antenna (located in top section of the beacon) must have an unobstructed
view of the sky. As long as 5 minutes may be required for the beacon to achieve a GPS signal lock. If GPS
synchronization is not established within 5 minutes of power-on, a GPS Sync Alarm is established. Following this
initial power up check, the GPS Sync Alarm will only activate if synchronization has been lost for over 1 hour.
Note: The alarm will clear once a GPS signal is locked. Refer to Section 4 if the Sync Alarm remains on for more
than 15 minutes.
