Overview

The FB9L is a universal lamp alarm relay designed to sensethe failure of flashing LED beacon lamps. It will monitor theoperation of one to eight beacons connected to a single flasherand/or auxiliary modules and the operation of the flasher. TheFB9L output relay energizes when one or more lamps fail. Allmonitored lamps must be the same wattage and voltage. The0.5A solid-state output energizes when a flasher failure is sensed.OperationWhen a LED beacon lamp fails, the FB9L senses a decrease incurrent flow. After a 10s lamp failure trip delay, the isolated SPDT(4-5-6) and non-isolated SPNO (3-1) relay contacts energize.These contacts are used to indicate a beacon failure hasoccurred. The “L” onboard LED indicator flashes green duringthe trip delay and glows red after the output relay energizes.Connected to a site monitoring system, it provides remotebeacon monitoring required by FAA-AC No: 150/5345-43E.The FB9L also monitors the operation of the flasher. If the flasherremains in the ON or OFF condition for more than 6s the solidstateoutput energizes and the “F“ flasher failure, onboard LEDglows red. This output is normally used to energize an externalflasher bypass relay. The contacts of the bypass relay are usedto route voltage around the failed flasher and to indicate analarm condition.Note: In a single flasher, single beacon system, if the beaconlamp fails, zero current flow is detected. This will cause theflasher failure output to energize after 6s and then the beaconfailure outputs after 10s. This is normal operation and can beexpected anytime zero current is flowing through themonitored conductor.
