With a battery backup kit that includes two 7 Amp Hour batteries, this power supply guarantees reliability during power interruptions. The available plug-in fire alarm interface board enhances safety features by allowing outputs to be configured as switched or unswitched. Certified by UL 294, ULC-S318, RoHS, and FCC Part 15, the PS904-4R-FA-BBK KIT is built to provide secure, filtered, and regulated power for all your access control needs, ensuring both performance and peace of mind.

KIT - 4 Amp Power Supply, 4 Relay Option Board, Plug-in Fire Alarm Relay, Battery Backup Kit with 2 Each 7 Amp Hour Batteries, 12/24VDC Field Selectable

Installation is simplified by utilizing a flat mounting design and polarized locking connectors for option boards. This design eliminates the need for racks and side connectors. The flat mounting of the option boards also provides for easier access to the terminal blocks for connection of electrified devices (such as electrified strikes, electromagnetic locks, card readers, etc.). Common to the line of PS900 series power supplies is a constant output rating at both 12V and 24V settings, universal 120VAC to 240VAC input, and polarized option board connectors. New fire alarm interface board mounting allows outputs to be configured as switched (power cut) or unswitched (power continues) when signal is provided.
