PS-Exit Exit Device
Power Supply
Installation Instructions
Overview
The Adams Rite PS-EXIT power supply provides power and control for up to two MLR
or LR exit devices. Each exit device is controlled by a timer that is initiated by a switch
closure. The timer is user-configured and holds the exit device(s) in the unlatched
position for 2 – 60 seconds. At the end of the selected time, the exit device(s) will
re-latch. If the switch controlling the exit device is closed longer than the selected
time, the exit device remains unlatched until the controlling switch is released.
• An optional mode is available that allows both retraction timers
to activate in response to a closure of either switch.
• The PS-EXIT is listed as an Exit Device, Access Control System Unit to UL294
requirements for power supplies and Canadian Standards CAN/CSA - C22.2.
• Exit devices under access system control remain latched during a
complete power failure but always allow free mechanical egress.
