Series: FB120A FB230A

Flasher and Incandescent Beacon Alarm Relay

Product Status| Activei

The FB120A and FB230A are used to monitor the operation of one two-lamp incandescent beacon and one beacon flasher (or auxiliary module). The flasher and lamps are monitored by sensing the flow of current in the circuit. If the lamp(s) or the flasher fail to operate properly, a solid-state output and an isolated SPDT relay energize. When connected to a site monitoring system, this unit provides the remote beacon monitoring protection required by the FAA/FCC. On a multiple beacon structure, one unit is required for each two-lamp incandescent beacon (one unit per beacon for LED beacons).

Operation
If one lamp in an incandescent beacon fails, the relay and solidstate lamp failure outputs energize after 10s. If the flasher fails in the ON or OFF condition, the relay and the solid-state flasher failure output energizes after 6s. If both failures occur, all three outputs energize after their trip delays.
Note: If both incandescent lamps fail, all three outputs will energize. The relay and solid-state flasher failure output energizes after 6s, and the solid-state lamp failure output energizes after 10s.

Toroidal current sensing
Failsafe beacon monitoring
One isolated, 5A, SPDT alarm output plus two, 1A, solid-state line voltage alarm outputs
Fixed trip delays for flasher (6s) and lamp (10s) failures

Reliable low cost monitoring of the flasher and lamps through built-in CT and provides isolation from the monitored circuit
Alarm monitors for failed incandescent lamps in addition to flasher function
When connected to a site monitoring system, it provides the remote beacon monitoring protection required by the FAA / FCC.
Prevents nuisance alarms
