Product Description
900-FA Von Duprin Fire Alarm Relay
Expert's Note: The 900-FA is a standalone fire alarm relay module that adds emergency fire alarm interface to any PS900 series power supply. When the fire alarm trips, this module overrides normal access control per your fire safety plan — unlock, lock, or fail-safe depending on the configuration. If you already have a non-FA distribution board installed and the spec just changed to require fire alarm, the 900-FA saves you from swapping the whole board.
That said — if you're ordering a new board and know you need fire alarm, buy the FA version of whatever board you need. It saves a board slot and simplifies wiring.
