An externally visible AC input indicator and isolated SPDT contacts enhance usability, while the high-voltage protective cover adds an essential layer of safety. The enclosure measures 14" x 12" x 4" and is designed with eight knockouts for flexible wiring options. Additionally, this power supply is equipped with battery backup capabilities, which auto-selects voltage, and offers an optional fire alarm interface board for enhanced functionality. Certified under UL 294, ULC-S318, RoHS, and FCC Part 15, the Schlage PS902-2RS-FA KIT is ideal for a variety of electrified devices, making it a reliable choice for both residential and commercial applications.

KIT - 2 Amp Power Supply, 2 Relay Option Board, Plug-in Fire Alarm Relay, 12/24VDC Field Selectable, Space for Battery Back-Up.

The Schlage comprehensive line of power supplies and option boards was designed 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 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 is provided.
