Its innovative fire alarm interface allows for outputs to be configured as either switched or unswitched, enhancing versatility. The enclosure, made from durable grey baked enamel, measures 14" x 12" x 4" and includes multiple knockouts for easy wiring. With built-in monitoring circuits and LED indicators for AC and DC outputs, the PS904-8F-BB KIT ensures operational transparency. Certifications such as UL 294 and RoHS underscore its reliability and compliance with industry standards, making it an ideal choice for security professionals and informed homeowners alike.

KIT - 4 Amp Power Supply, Fused 8 Zone Option Board, Battery Backup Board Only, 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.
