Review: Great value and super easy to fit! - These burglar alarm contacts have been excellent so far.

One reviewer even mentioned they were “perfect fit for replacing an Aritech sensor” . Why it stands out: Excellent value — you get two detectors, so one for now and a spare; as noted by a customer: “for the money it’s great and saved a call‑out charge” . Quick and easy installation — the “very quick to install” process receives consistent praise . Reliable performance — firm magnetic switches and strong wiring quality keep everything functioning reliably .

After fitting the new ones chimes did not work at all and investigation showed that one of the new detectors was permanently open circuit, if I had not been desperate I would have returned the new ones for a refund but as one of the old detectors was still working I opted to refit the old one together with the “good” new one Since contacting supplier they have resolved the issue hence revised rating from 3 to 4 ## Frequently Bought Together - 2 Pack of Burglar Alarm Door/Window Contact Detectors - Wired - White - Professional Quality - 6 Way Junction Box Suited to Burglar Alarms and other Low Voltage Systems. - Ali's DIY 6 Core White PVC Insulated Alarm Cable - 3 Metre Custom Cut Length --- ## 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.vn/products/509660038-2-pack-of-burglar-alarm-door-window-contact-detectors-wired](https://www.desertcart.vn/products/509660038-2-pack-of-burglar-alarm-door-window-contact-detectors-wired) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-20*
