The M&S DRW Door Release Mechanism is compatible with the M&S DMC1, DMC3-4 and DMC-10 system and the NuTone NM100 and NM200 systems to grant access through a controlled door. It is an electromechanical device that will release a door strike when activated and is designed to be installed on a wooden door jam.
The RT11 Power Transformer is required to power the door release mechanism and provides a relay contact closure to switch the power from the transformer to the door release.
