• PS902 x 900FA Locknetics Power Supply w/ Fire Alarm relay (EIR)

*Actual product and finish may vary

The Locknetics by Schlage PS902 x 900FA Power Supply w/ Fire Alarm Relay (EIR) is designed as part of a comprehensive line of power supplies and option boards to address the changing needs of the access control market.

Installation is simplified by utilizing a flat mounting design and polarized locking connectors for option boards. This new 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 120 VAC to 240 VAC 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 provided.

* All PS900 Series of power supplies and option boards have been tested and certified to meet UL 294.
