Security Door Controls MD-31DB Black PIR Request-to-Exit Sensor

Provide touch-free egress activation at controlled doors with a passive infrared request-to-exit sensor. The Security Door Controls MD-31DB detects motion from people approaching the exit side of a doorway and sends a request-to-exit signal to the connected access-control system. This function supports normal pedestrian egress while the door remains controlled by the installed locking and access-control equipment. Position a motion-based request-to-exit device where users need to leave through a secured opening without locating or operating a push switch. Passive infrared sensing makes the MD-31DB appropriate for hands-free exit activation at doors where a physical request device may be less convenient. The sensor's role is limited to initiating the request-to-exit event; the connected system determines the release action and timing. This version has a black finish, allowing the sensor to coordinate with dark door frames, wall surfaces, and nearby security hardware. Its passive infrared sensing method distinguishes it from manually operated exit controls by detecting occupant movement rather than requiring contact. Use it where the access-control design calls for a dedicated motion-triggered request-to-exit sensor at the protected opening.
