Security Door Controls MD31D Request-To-Exit PIR Sensor
SDC’s Request-to-Exit (RTE) sensors offer basic and full-featured models to suit every access control application. The quick-install sensors are extremely flexible, provide a generous amount of wiring room and contain built-in internal “tamper proof” shutters to enable precise target area detection.The SDC MD31D passive infrared detector is specifically designed for request-to-exit applications. It has an adjustable 1-60 second time delay. The coverage field is internally pointable. When angled 14ᄎ down, coverage may be 5 x 6 feet at 7 feet high to 10 x 12 feet at 15 feet high. The MD31D projects a wrap around “U” pattern down and away from the door to inhibit tampering. The MD31D may be mounted to the frame header, wall or ceiling. Complies with NFPA applications.Input: 12 or 24 VAC/DC @ 26mA max.Contact: 2 SPDT Dry, 2 Amp @ 30VDC (38.1 H x 148.8 W x 38.1 D mm)Operating temp: -20° F to 120° F (-29° C to 49° C)Dimensions: 1.5" H x 6.25" W x 1.5" D Features: Specifications: • Adjustable relay time (0.5 - 64 seconds)• Micro-based signal processing• Adjustable “tamper proof” shutters—to enable precise target area detection• Two “Form C” outputs• Swivel optics – allow for offset mounting• Patented black bug guard• Available in white or black MD31D-W PIR motion detector, whiteMD31D-B PIR motion detector, black• Range: From 5.5' x 2' ( 1.67m x 0.6m) up to15.8' x 8.4' (4.8 x 2.5m) depending on mounting height• Mounting Height: 7' to 15' (2.13m x4.51m)• Detectable Walk Rate: 0.5'-10'/sec• Signal Processing: RTE and Security modes• Temperature Compensation: Advanced dual-slope• Alarm Relay: Two “Form C” outputs• Input Voltage: 12-24 volts AC or DC• Standby Current: 35mA• Indicators: Green (ready) LED• Operating Temperature:14°F to 122°F (-10°C to 50°C)• Dimensions: 7" L x 2" H x 2" D(17.7cm x 5cm x 5cm)
