KIT - 4 Amp Power Supply, Fused 8 Zone Option Board, Plug-in Fire Alarm, 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.
