Von Duprin/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.
