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. Quad detectors also provide superior catch performance versus a standard PIR or dual-technology detector. They are particularly well suited for challenging installation situations; for example, cases
where cross catch of intruders cannot be guaranteed or where intruders are able to cross the detection pattern very quickly.
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.
This eliminates the need for the installer to select the sensitivity level, thus improving ease of installation and
reliability.
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.
Sealed Optics and Electronics
The optics and electronics are assembled into the front enclosure and sealed with a protective cover to
prevent damage during installation. The sealed optical chamber also prevents drafts and insects from
affecting the detector.
