SDC’s MD-31D series motion sensors are passive infrared
detector 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 wrap around “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
