The Adams Rite PS-EXIT power supply is designed specifically to protect and optimize the performance of Adams Rite 8000/3000 Series exit devices that have Motorized Latch Retraction (MLR) or Electric Latch Retraction (LR) options by delivering filtered and regulated power.
This power supply is designed to provide power and control for up to two MLR or LR exit devices. Each exit device is controlled by a timer that’s 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 relatch. If the switch that controls the exit device is closed longer than the selected time, the exit device will remain unlatched until the controlling switch is released.
