Bosch Blue Line Tritech PIR Detector 12m Pet Friendly up to 45KG BDL2-WP12G
The Bosch BDL2-WP12G is a Blue Line Gen2 TriTech motion detector that combines passive infrared (PIR) with microwave detection, so both technologies have to agree before it raises an alarm. That dual-technology approach cuts false alarms, and a selectable pet-immunity mode lets it ignore one or two pets up to 45 kg while still catching intruders. It covers 12 m x 12 m wall-to-wall and is a wired detector for a hardwired Bosch alarm panel.

01Overview
What this product is
The Bosch BDL2-WP12G is a Blue Line Gen2 TriTech detector — a dual-technology motion sensor that pairs passive infrared with microwave Doppler radar. Because both the PIR and the microwave have to agree before it triggers, it is much less prone to the false alarms a single-technology PIR can produce from heat, drafts or moving objects. It covers a 12 m x 12 m area wall-to-wall at a 94° angle, enough for most rooms.
Its pet-friendly mode is selectable. With pet immunity turned on it distinguishes people from animals and ignores one or two pets up to 45 kg, or numerous rodents, while still detecting human intruders; with it turned off it gives full catch performance for pet-free areas. First Step Processing sets the sensitivity automatically so there is nothing to adjust in the field, microwave noise adaptive processing filters repetitive background movement, and dynamic temperature compensation keeps detection reliable across hot and cold conditions. A sealed optical chamber keeps drafts and insects out.
Some honest, practical detail: it is a wired detector with a normally-closed relay output and tamper, made to connect to a hardwired Bosch alarm panel rather than work wirelessly. The recommended mounting height is 2.2 m to 2.75 m with no adjustments needed, and it can be wall, corner or ceiling mounted — but note that pet immunity is no longer assured once it is ceiling-mounted. It is EN50131 Grade 2 certified and genuine Bosch stock with local warranty.

04Why choose this
Built for the way you actually use it
Pet-friendly when you need it
Selectable pet immunity ignores one or two pets up to 45 kg while still catching intruders, and can be switched off for pet-free rooms.
Set and forget
First Step Processing auto-sets sensitivity and temperature compensation keeps it accurate hot or cold, so there is nothing to adjust after mounting.
Reliable Bosch detection
Wall-to-wall 12 m coverage, a sealed optical chamber and EN50131 Grade 2 certification make it dependable in homes and small business.
05Where it fits
Right at home in these scenarios
Homes with pets
Protect a living room or hallway where a dog or cat roams, with pet immunity on for animals up to 45 kg.
False-alarm-prone rooms
Use the dual technology in rooms with heaters, sunlight or air movement where a plain PIR would trigger falsely.
Living rooms and offices
Cover a 12 m x 12 m room wall-to-wall from a single wall or corner position.
Upgrading a single-tech detector
Replace an older PIR that false-alarms with a TriTech detector for steadier, more trustworthy operation.

Installation requirements
Mount it level on a wall or in a corner at 2.2 m to 2.75 m, or on the ceiling with the optional B338 bracket if you do not need pet immunity. Wire the normally-closed alarm output to a detection zone and the tamper to a 24-hour circuit on your panel. Set pet immunity on or off to suit the room, then walk-test the coverage before arming. No field sensitivity adjustment is required.
