Product Description
900-4R-FA Von Duprin Power Supply Board with Fire Alarm Relay
Expert's Note: The 900-4R-FA is the fire alarm version of Von Duprin's 4 relay distribution board. Four independently controlled relays for powering multiple electrified devices, plus integrated fire alarm emergency interface — all in one board. When the alarm trips, all four outputs respond per your fire safety configuration. Saves a board slot and simplifies wiring vs adding a separate 900-FA to a standard 900-4R.
