SDC’s MD-31D series motion sensors are passive infrared detectors specifically designed for request-to-exit applications. The coverage field is internally pointable. When angled 14 degrees down, coverage may be 5’ x 6’ at 7’ feet high for 10’ x 12’ at 15’ high. The MD-31D projects a wraparound “U” pattern down and away from the door to inhibit tampering.
The MD-31D complies with national fire and building code requirements for access-controlled egress doors listed below:
IBC International Code 1008.1.3.4
IFC International Fire Code 1008.1.3.4
NFPA 101 Life Safety Code 7.2.1.6.2
NFPA 1.15.5.3.2
BOCA National Building Code 1017.4.5
SBCCI Standard Building Code 1012.7
STANDARD FEATURES
