The Blue Line Gen2 Quad PIR Detector (ISCBPQ2‑W12) uses two individual sensors that operate like two PIRs in one detector. Each sensor processes signals separately. Both must activate to generate an alarm signal. This improves false alarm immunity relative to a standard PIR, because false alarm sources such as noise spikes and small animals are ignored.
First Step Processing (FSP) First Step Processing (FSP): almost instantly responds to human targets without producing false alarms from other sources. FSP adjusts the detector's sensitivity based on signal amplitude, polarity, slope, and timing.
Dynamic Temperature Compensation The detector intelligently adjusts its sensitivity to maintain its ability to identify human intruders at virtually any temperature.
Wall-to-Wall Coverage An improved lookdown zone and coverage range of 12 m x 12 m (40 ft x 40 ft) provide wall-to-wall coverage.
Self-locking Enclosure The sliding self‑locking enclosure has an integrated bubble level and custom gap‑free, lift‑gate style terminal blocks to make installation easier.
