You can pair the entire alarm system with Alexa, but none of the additional sensors (door, motion etc) will work without the alarm system. **Q: I dont have white windows, it would be nice if the contact sensors came in brown as I would the buy then.** A: They don’t do brown that I am aware off however they do black sensors which are designed to be outside but would work. Alternative is to spray them the colour you want **Q: Does this does the sensor work on a letterboxwork on a letterbox** A: Yes it should work on a letterbox provided you have surfaces wide enough to stick the sensors to two flat surfaces and keep close together to engange the signal .Once the contact is broken by opening the letterbox the alarm will sound on the control panel if not in disarmed mode. **Q: Any idea where these are made?** A: It’s working very good and very sensitive --- ## 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.ae/products/372189193-alarm-contact-sensor-2nd-generation-2-pack](https://www.desertcart.ae/products/372189193-alarm-contact-sensor-2nd-generation-2-pack) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-06-17*
