    Key features
    Dual technologyA dual-element pyroelectric infrared sensor and a microwave sensor confirm motion together, and the microwave frequency is 10.53 GHz.
    360° coverageFrom the ceiling it scans every direction, covering Φ7 m at 2.5 m height, Φ12 m at 3.6 m and Φ13 m at 4.5 m.
    White light resistanceIt withstands white light up to 6,500 lux.
    Temperature compensationTwo-way digital temperature compensation holds sensitivity as the ambient temperature changes.
    Motion speedIt detects movement between 0.3 m/s and 3 m/s.
    OutputsIt carries 1 alarm output (NC/NO, 28 VDC, max. 100 mA) and 1 case tamper output (NC, 28 VDC, max. 100 mA).
