Product Description
900-4R Von Duprin Power Supply Board — 4 Relay Distribution
Expert's Note: When you've got 3-4 electrified devices running back to one power supply closet, the 900-4R is the board. Four independently controlled relays means each device gets its own circuit — a fault or activation on one doesn't affect the others. Common on lobby configurations, multi-door entries, and retail storefronts where you need centralized power distribution.
Plug and play into any Von Duprin PS900 series enclosure. For fire alarm integration built into the board, go with the 900-4R-FA instead of adding a separate 900-FA.
