As these come preset from manufacturer. Connectivity tested. You can stick them up or screw them up. I screwed them up. Review: They go off for no reason - If you like your sleep, dont buy these! Ive had these alarms for less than 2 months and they have gone off in the middle of the night 3 times for no reason! It is not that one unit is faulty because its a different one that sets them all off each time. The monoxide alarm went off so I had my gas appliances checked out and still there was nothing wrong. ## Features - Convenient Pre-Linked Bundle: Our bundle is pre-linked for easy installation – no setup required.

Installation was quick and straightforward — no need for complex wiring, just mount them and link them up following the simple instructions. Within minutes, all the units were communicating perfectly with each other. The interlinked feature is fantastic — if one alarm goes off, they all do. It gives me real peace of mind knowing that everyone in the house will be alerted immediately, no matter where the danger starts. The build quality feels solid, and the alarms are loud and clear without being shrill. I also appreciate the test/silence button, which makes it easy to do regular safety checks. Overall, these smoke alarms are reliable, easy to install, and provide an essential layer of safety for any home. Highly recommend. ## Frequently Bought Together - Wireless Interlinked Smoke,Heat and Carbon Monoxide Alarm Kit,Pre-linked,Compliant with Scotland & England Law, Remote Slience Function(3 Smoke + 1 CO + 1 Heat) - Smoke Alarm,10 Years Battery Life,Interlinked Smoke Alarms, Fire Alarms for Home Scotland Interlinked,Smoke Detector Can Remote Control,Compliant with EN14604, CE Certified (1 Interlinked Smoke) - Smoke Alarm, Interlinked Smoke and Heat Alarm Scotland Bundle, Pre-linked,10-Year Battery Life,Compliant with Scotland & England Law (2 Smoke + 1 Heat) --- ## 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.us/products/593001571-wireless-3-smoke-1-carbon-monoxide-detector-1-heat-alarm](https://www.desertcart.us/products/593001571-wireless-3-smoke-1-carbon-monoxide-detector-1-heat-alarm) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-08*
