Also known as -BLUE LINE GEN2 TRITECH MOTION PERPDETECTORS 40FT BY 40FT-Bosch BDL2-WP12G TriTech Motion Detector Pet Immune Review: Great sensor but needs better instructions. - I purchased this device on November 7, 2024, and finally gathered the courage to install it. First, I’d like to mention that my old sensor, a Honeywell Model DT-720B, lasted an impressive 18 years. Recently, after reactivating the *Away* feature (when no one is home), we encountered an issue while on a trip. The alarm company unexpectedly called to inform me that the sensor had been triggered. I immediately turned on my cameras, but everything appeared fine. The alarm company explained that the alarm would keep ringing unless another motion was detected. Sure enough, it went off again, leaving us no choice but to instruct the company to tell the police to stand down. When we returned from vacation, a technician inspected the system but found no issues. However, he recommended replacing the sensor for around $100, including the new Bosch BDL2-WP12G TriTech Motion Detector Pet Immune device. He suggested that the Honeywell sensor was likely giving false alarms due to its age. At first, we decided against replacing it. But one day, while sitting in the backyard with my wife, I decided to test the system by arming the alarm in *Away* mode. Within five minutes, the alarm went off again, confirming the problem. That’s when I decided to purchase the Bosch sensor. Although it took me 30 days, I finally installed it. ### Installation Notes: For those considering an upgrade, this Bosch device is slightly smaller than the Honeywell DT-720B. I had to unscrew the old sensor and drill new holes for the Bosch device. It comes with a bubble level to help ensure proper alignment, but due to how my old sensor was mounted, leveling it perfectly wasn’t feasible. Instead, I aligned it as closely as possible to the old device’s position. **Wiring:** The wiring process was tricky, as I couldn’t find a clear comparison guide for older devices despite extensive online searches and watching YouTube videos. The Bosch sensor comes with six connections: 1. Negative (–) 2. Positive (+) 3. NC 4. NC 5. T 6. T In contrast, my old Honeywell DT-720B had only four connections: - **C**: Connected to the green wire - **NC**: Connected to the yellow wire - **V–**: Connected to the black wire - **V+**: Connected to the red wire Initially, I connected the Bosch’s Negative and Positive terminals without issue. However, I mistakenly wired one NC and one T connection for the other wires. While the sensor seemed to power on, it didn’t trigger the alarm when I walked around the house. After more research, I found another video explaining that both the green and yellow wires should be connected to the two NC terminals, as the T connections are primarily used for business applications. Once I rewired it correctly, the sensor worked perfectly. I tested it by walking around the house while the alarm was armed, and it immediately triggered the system, prompting a call from the alarm company. ### Performance: In the attached pictures, you can see my old and new wiring setups. That same day, we left the house with the *Away* mode armed. It worked flawlessly—even with the fan, TV, and my Roborock Q Revo Plus vacuum running in the same room as the sensor, it didn’t trigger false alarms. So far, I’m very pleased with this device. I hope it last a litte longer.

I wanted to add this one on and work like the others. It is a perfect fit and easy hook up 4 wires l ike the old ones. This one like my old ones are NC (Normally Closed). I then hooked up this panel to the Ring Retrofit Alarm Kit. Everything works perfectly. No false alarms. Nice blue light to indicate motion. ## Frequently Bought Together - Bosch BDL2-WP12G TriTech Motion Detector Pet Immune - Honeywell WAVE-2 Two Tone Siren - Honeywell Intellisense FG-1625 Acoustic Glassbreak Sensor 25 Ft. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/1162452-bdl2-wp12g-tritech-motion-detector-pet-immune](https://www.desertcart.co.uk/products/1162452-bdl2-wp12g-tritech-motion-detector-pet-immune) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-21*
