Bosch ISC-BDL2-WP12G Blue Line Gen2 Pet-Friendly TriTech Motion Detector, 40' x 40' Coverage, PIR, Microwave, 10.525 GHz

The Bosch ISC-BDL2-WP12G is a Blue Line Gen2 TriTech pet-friendly motion detector combining passive infrared (PIR) and 10.525 GHz microwave detection with 40 x 40-foot coverage and selectable pet immunity up to 100 lbs. Designed for residential and commercial intrusion alarm systems, it features First Step Processing, Microwave Noise Adaptive Processing, dynamic temperature compensation, and wall-to-wall motion detection. The detector operates on 9-15 VDC, draws 10 mA at 12 VDC, and includes a normally closed alarm output, cover tamper switch, and sealed optical chamber.

Bosch ISC-BDL2-WP12G Blue Line Gen2 TriTech Pet-Friendly Motion Detector

The Bosch ISC-BDL2-WP12G is a dual-technology intrusion motion detector combining passive infrared (PIR) and microwave sensing with selectable pet-friendly detection for residential and commercial security systems. Part of the Bosch Blue Line Generation 2 TriTech Series, the detector provides 40 x 40 feet (12 x 12 meters) of motion detection coverage using PIR and 10.525 GHz microwave technologies to identify human movement within a protected area. Its selectable Pet Friendly feature is designed to reduce unwanted alarms caused by one or two pets weighing up to 100 lbs (45 kg) when installed and configured according to Bosch's guidelines. The pet immunity setting can be disabled for installations where standard intrusion detection is preferred. Designed for homes, offices, retail businesses, warehouses, and other indoor protected spaces, the ISC-BDL2-WP12G combines dual-technology detection with advanced signal processing to improve alarm reliability while reducing nuisance activations caused by environmental disturbances.

The ISC-BDL2-WP12G incorporates Bosch First Step Processing (FSP), Microwave Noise Adaptive Processing, and Dynamic Temperature Compensation to distinguish potential intruder movement from environmental interference. First Step Processing evaluates changes in infrared energy and adjusts signal processing to detect human movement while reducing unnecessary alarm activations. Microwave Noise Adaptive Processing identifies repetitive environmental disturbances and adjusts microwave signal evaluation to minimize false alarms caused by non-threatening movement. Dynamic Temperature Compensation automatically adjusts PIR sensitivity as ambient temperatures change, supporting detection performance when the temperature of a person approaches the surrounding room temperature. The detector also features wall-to-wall coverage and an enhanced look-down detection zone to monitor movement near the installed sensor. Its combined PIR and microwave architecture provides greater resistance to environmental disturbances than a conventional single-technology PIR detector. The microwave sensing circuit operates at 10.525 GHz, with an adjustable Doppler range control for matching the microwave coverage to the protected area.

The Bosch ISC-BDL2-WP12G operates on 9-15 VDC with a nominal current consumption of 10 mA at 12 VDC, supporting connection to compatible hardwired intrusion alarm control panels and listed power-limited security supplies. The detector includes a supervised, solid-state Form A normally closed alarm output rated at a maximum of 100 mA at 25 VDC, along with a separate normally closed cover tamper contact rated at 100 mA at 25 VDC for monitoring unauthorized enclosure opening. Its white housing measures 4.2 inches high, 2.4 inches wide, and 1.7 inches deep (105 x 61 x 44 mm) and is manufactured from high-impact ABS plastic. The detector features a sliding, self-locking enclosure with an integrated bubble level to simplify installation and alignment. A sealed optical chamber protects the PIR sensing components from drafts, insects, and contamination, while an externally visible alarm LED can be disabled after installation. Wiring connections support compatible conductors from 16 to 26 AWG, subject to applicable installation and listing requirements.

The ISC-BDL2-WP12G supports wall, corner, and optional ceiling mounting, with a recommended installation height of 7.5 feet (2.2 meters) and a supported mounting range of approximately 7.5 to 9 feet (2.2 to 2.75 meters). Its mounting design requires no optical adjustment when installed within the specified height range, while compatible accessories include the B328 gimbal mounting bracket, B335-3 low-profile swivel bracket, and B338 universal ceiling mounting bracket. The detector operates in temperatures from -4 F to +131 F (-20 C to +55 C) under current manufacturer specifications, with UL installations restricted to 32 F to 120 F (0 C to 49 C). The ISC-BDL2-WP12G is UL 639 Listed for intrusion detection applications and carries applicable FCC and Canadian regulatory approvals. Bosch specifies that the pet immunity feature is not evaluated under its UL/cUL listing and requires installation according to the manufacturer's pet-friendly configuration guidelines. Compared with the ISC-BDL2-W12G standard TriTech detector, the ISC-BDL2-WP12G adds selectable pet immunity, while the ISC-BDL2-WP6G provides a smaller 20 x 20-foot detection area. Its combination of dual-technology motion sensing, 100 lb pet-friendly configuration, environmental signal processing, low power consumption, and flexible mounting options makes the ISC-BDL2-WP12G suitable for professionally installed residential and commercial intrusion alarm systems.
