Bosch ISC-BPR2-W12 Blue Line Gen2 PIR Motion Detector, 40'x40' Coverage

The Bosch ISC-BPR2-W12 is a Blue Line Gen2 passive infrared (PIR) motion detector providing 40 x 40 ft (12 x 12 m) coverage for residential and commercial intrusion alarm systems. Featuring dual Fresnel lenses, a 77-zone detection pattern, First Step Processing (FSP), and dynamic temperature compensation, the detector identifies human movement while reducing nuisance alarms. It operates on 9-15 VDC at 10 mA and includes a selectable look-down zone, tamper switch, and integrated mounting level.

Bosch ISC-BPR2-W12 Blue Line Gen2 PIR Motion Detector, 40 ft Coverage

The Bosch ISC-BPR2-W12 Blue Line Gen2 PIR motion detector provides indoor intrusion detection across a 40 x 40 ft (12 x 12 m) coverage area for residential properties, commercial offices, retail facilities, and small business security systems. Using passive infrared sensing, the detector identifies changes in thermal energy associated with movement through its monitored area. Its dual Fresnel lens system produces a high-density pattern of 77 detection zones across seven layers, with three additional selectable look-down zones for detecting movement directly beneath the sensor. The detector incorporates First Step Processing (FSP) to analyze infrared signals and distinguish potential intruder activity from environmental disturbances, supporting accurate detection without manual sensitivity adjustments.

The ISC-BPR2-W12 operates on 9-15 VDC with a typical current consumption of 10 mA at 12 VDC, supporting integration with compatible hardwired intrusion alarm control panels. Its solid-state, normally closed (NC) alarm output is rated for 100 mA at 25 VDC, while a separate normally closed cover tamper contact provides enclosure monitoring. The white, high-impact ABS plastic housing measures 4.2 inches high, 2.4 inches wide, and 1.7 inches deep (105 x 61 x 44 mm). The detector operates within an ambient temperature range of -20 F to 130 F (-30 C to 55 C), with a restricted range of 32 F to 120 F (0 C to 49 C) for UL-listed installations. Its sealed optical chamber protects the sensing components from drafts, insects, and installation debris.

The Bosch Blue Line Gen2 ISC-BPR2-W12 combines dynamic temperature compensation, First Step Processing, and wall-to-wall PIR coverage to maintain intrusion detection performance under changing indoor conditions. FSP evaluates signal amplitude, polarity, slope, and timing to determine when movement warrants an alarm signal, while temperature compensation adjusts detection sensitivity as ambient conditions change. Installation is supported by a self-locking sliding enclosure, integrated bubble level, and gap-free terminal blocks. The recommended mounting height is 7.5 to 9 ft (2.2 to 2.75 m), with no manual detection-pattern adjustment required when installed according to manufacturer instructions. Mounting options include flat-wall and corner installation, with separately available B328 gimbal, B335-3 swivel, and B338 ceiling mounting brackets for applications requiring alternative positioning.

The Bosch ISC-BPR2-W12 wired motion sensor is designed for indoor intrusion alarm systems requiring dependable PIR detection and low operating current. Its IP30 enclosure rating and IK04 impact resistance classification support installation in protected interior environments, while manufacturer documentation identifies compliance with EN 50131-2-2 Grade 2, EN 50130-5 Class II, UL 639, and CAN/ULC-S306 standards. A configurable alarm LED supports walk testing and can be disabled after commissioning, and the cover tamper circuit provides notification when the enclosure is opened. The ISC-BPR2-W12 is the standard PIR model; the separately available ISC-BPR2-WP12 provides selectable pet immunity for animals weighing up to 45 lbs (20 kg). Bosch identifies a five-year warranty for the Blue Line Gen2 detector series. Installers must verify panel compatibility, detection coverage, mounting location, and environmental conditions before installation.
