Von Duprin PS906-4RL-FA 6 Amp Power Supply, 4 Relay Controlled Logic Board, Emergency Interface Relay Integrates with Fire Alarm
The Von Duprin PS906-4RL-FA Power Supply delivers a dependable 6 amp regulated output with field-selectable 12/24VDC operation and includes a factory-installed 900-4RL logic relay board and 900-FA emergency fire alarm interface relay. Designed for advanced access control applications, the 4RL logic board supports time delay, auto-operator coordination, and security interlock functions, making it ideal for electrified panic devices, electric strikes, magnetic locks, and electrified trim. The integrated fire alarm interface ensures power is interrupted during emergency conditions to meet life-safety requirements. Featuring universal 120–240VAC input, overload protection, LED status indicators, and a hinged locking enclosure, the PS906-4RL-FA is UL 294 and ULC-S318 listed and built for healthcare, education, government, and high-security commercial installations requiring intelligent power distribution and fire alarm integration.
