    Key features
    Dual technologyA dual-element pyroelectric infrared sensor and a microwave sensor work together, and an intelligent review algorithm confirms the alarm.
    Pet immunityIt keeps animals weighing up to 25 kg out of the alarm.
    White light resistanceIt avoids false alarms under white light up to 6,500 lux.
    Temperature compensationTwo-way digital temperature compensation holds sensitivity as the ambient temperature changes.
    Alarm rulesAND/OR logic, dynamic threshold and 1P/2P pulse count narrow the trigger condition to the site.
    OutputsIt carries 1 alarm output (NC/NO, 60 VDC, max. 400 mA) and 1 case tamper output (NC, 28 VDC, max. 100 mA).
