Bosch ISC-PDL1-WA18G Professional Series TriTech+ Motion Detector with Anti-Mask

The Bosch ISC-PDL1-WA18G is a Professional Series TriTech+ indoor motion detector with MANTIS anti-mask protection, designed for commercial intrusion alarm systems. Combining passive infrared (PIR) sensing, 10.525 GHz microwave detection, and sensor data fusion, it provides selectable coverage of 60 80 feet or 25 33 feet. The detector features 86 detection zones, active white light suppression, dynamic temperature compensation, and cover/wall tamper monitoring. Operating at 9-15 VDC, it includes normally closed alarm and trouble outputs, remote walk testing, and multicolor diagnostic LEDs for reliable indoor security monitoring.

The Bosch ISC-PDL1-WA18G Professional Series TriTech+ Motion Detector provides dual-technology intrusion detection for commercial and institutional security systems. Combining passive infrared (PIR) detection with 10.525 GHz microwave radar, the detector uses Bosch Sensor Data Fusion technology to evaluate multiple sensing inputs before generating an alarm. Its Tri-Focus optics divide the detection area into 86 zones arranged across 11 detection curtains, helping identify movement throughout the protected area. The detector provides selectable coverage of 60 80 feet (18 25 m) or 25 33 feet (8 10 m), making it suitable for offices, retail stores, warehouses, financial institutions, schools, and other indoor locations requiring dependable motion detection and resistance to alarm interference.

The ISC-PDL1-WA18G incorporates Bosch MANTIS anti-mask technology, which uses active infrared sensing to detect attempts to obstruct or cover the detector with materials such as tape, fabric, paper, plastic, or spray. When enabled, the anti-mask function monitors objects placed within approximately 12 inches (30 cm) of the sensor and signals a trouble condition to compatible intrusion alarm equipment. Additional detection technologies include Cloak and Camouflage Detection Technology (C2DT), Range Adaptive Radar, active white light suppression, and dynamic temperature compensation. These features improve detection of intruders attempting to conceal their infrared signature while reducing unwanted alarms caused by lighting changes, temperature variations, and environmental disturbances. The sealed optical chamber also helps reduce interference from drafts, insects, and small animals weighing less than 10 pounds (4.5 kg), although the small-animal immunity feature was not evaluated under the detector's UL listing.

The Bosch ISC-PDL1-WA18G operates from a regulated 9-15 VDC supply, with manufacturer-specified current consumption of approximately 18 mA in standby and less than 26 mA at maximum operation. A normally closed solid-state alarm relay provides a supervised output rated at 125 mA, 25 VDC, or 3 watts, while separate normally closed tamper and trouble contacts support additional monitoring. The detector includes cover and wall tamper protection, alarm memory, remote self-testing, and low-input-voltage supervision. Three diagnostic LED colors distinguish operating conditions: blue indicates TriTech+ alarms, yellow identifies microwave detection, and red indicates PIR detection. The LEDs automatically adjust their brightness to surrounding light levels. Configurable DIP switches provide long- or short-range selection, anti-mask enablement, walk-test settings, and alarm memory control for compatible hardwired intrusion systems.

The ISC-PDL1-WA18G features a white, high-impact ABS plastic enclosure measuring approximately 5 2.75 2.25 inches (127 69 58 mm), with a self-locking cover and built-in bubble level for accurate positioning. Bosch specifies a mounting height of 7-10 feet (2.1-3 m), with flat-wall and corner mounting supported using the supplied installation hardware. Optional accessories include the B328 gimbal mounting bracket, B335-3 low-profile swivel bracket, and B338 universal ceiling bracket. The detector has IP41 ingress protection and IK04 impact resistance, with an operating temperature range of -22 F to 130 F (-30 C to 55 C); UL-certified installations are limited to 32 F to 120 F (0 C to 49 C). Manufacturer documentation identifies UL 639, ULC-S306, and EN 50131-2-4 Grade 3 compliance for applicable configurations. The ISC-PDL1-WA18G is intended for indoor use with compatible hardwired intrusion alarm panels, and installation must follow Bosch's mounting, wiring, walk-test, and anti-mask calibration procedures.
