Security Door Controls MD-31DOW White PIR Request-to-Exit Sensor

Detect motion at the egress side of an access-controlled opening with passive infrared sensing. The white Security Door Controls MD-31DOW request-to-exit sensor provides motion-activated exit initiation for door systems that require a REX input as part of their normal egress operation. Its PIR sensing method supports hands-free activation as a person approaches the exit area. Use this sensor at controlled doors where request-to-exit operation must be initiated by occupant movement rather than by a card presentation at the exit side. It fits physical-security door applications that use an access-control system to manage locking and egress behavior. The sensor’s purpose is focused: detect movement and initiate the request-to-exit function for the connected door-control installation. This specific version is supplied in white, allowing it to visually align with white wall surfaces, trim, or nearby door hardware. The MD-31DOW is a PIR-based request-to-exit device rather than a credential reader or locking component. Select it where a white motion-sensing REX device is required for an access-controlled egress opening.
