SDC MD-31D

The MD-31D is a highly customizable passive egress sensor. While paired with your access control system you can adjust the relays to signal access or control a magnetic lock, which can then be set to a 1 to 60 second time delay. Both failsafe and failsecure options are available to suit your needs. Adjustable sensitivity and view shutters allow for more focused detection in areas where increased foot traffic may unintentionally trip the sensor. The coverage range is even projected in a U pattern to deter tampering. Available in either black or white.
