ISN-AP1 Passive-Infrared Detectors
The new ISN-AP1 and ISN-AP1-T PIR detectors deliver economical, reliable performance in applications with a low number of false-alarm sources. Both offer the same features with the exception that the ISN-AP1-T also has a cover tamper switch which is required for EN50131 grade 2.
Bosch Security Systems is introducing a range of passive infrared (PIR) motion detectors for low-risk environments (EN50131-2-2 grade 1 and grade 2 risk levels). The detectors incorporate an embedded microcontroller with sophisticated signal processing, including Bosch’s proprietary First Step Processing (FSP) that responds to human targets virtually instantly without producing false alarms from other sources. FSP, moreover, automatically adjusts the detector's sensitivity to suit critical parameters in its surroundings such as signal amplitudes and timing, eliminating the need for the installer to select the sensitivity level. PIR sensitivity is also automatically adjusted to identify human intruders at critical temperatures, accurately detecting human body heat and further reducing false alarms.
