Description
The PS-EXIT Power Supply is engineered to safeguard and enhance the functionality of Adams Rite 8000/3000 Series exit devices equipped with Motorized Latch Retraction (MLR) or Electric Latch Retraction (LR) capabilities, providing them with filtered and regulated power essential for optimal performance.
**Functionality:**
This power supply unit is tailored to provide power and control for up to two MLR or LR exit devices. Each device is governed by a timer activated by a switch closure, which is configurable by the user to hold the exit devices in an unlatched position for 2 to 60 seconds. Once the designated time elapses, the devices automatically relatch. If the switch remains closed beyond the preset time, the exit devices remain unlatched until the switch is released.
– An optional mode allows simultaneous activation of both retraction timers upon closure of either switch.
– When integrated into an access control system, these exit devices remain latched during a total power loss, while ensuring they provide free mechanical egress.
**Key Features:**
– **Housing:** The enclosure is a hinged, steel cabinet measuring 10″ x 10-3/8″ x 4-1/8″ [254 mm x 263.5 mm x 104.8 mm], finished in a durable blue baked enamel. It includes knockouts for conduit connections and space to hold two sealed, lead-acid batteries (7AH, not included).
– **Timer:** Operated by a switch closure to control each exit device, the timer is user-configurable, allowing devices to remain unlatched for 2 to 60 seconds, after which they automatically relatch.
– **Operating Modes:** The PS-EXIT supports powering up to two 8000/3000 MLR or LR exit devices through the following modes:
– **Single Input (Sequential Operation):** Activating one input retracts the corresponding exit device, followed by the retraction of the second device, suitable for controlling a double-door exit with one input.
– **Dual Input (Independent Operation):** Each exit device is controlled by its dedicated input switch, enabling management of two separate exits with independent controls.
