With the old bases removed from the ceiling, one of the two alarms I was replacing could just about be forced on, but certainly not when it was attached to the ceiling. **Q: Hi there, Does this come with mounting base. The one i am replacing, the mounting base is damaged. So i want the whole unit.** A: Yes. It comes with a new base **Q: I am due to replace 2 mains heat alarms model ei144. is it possible to use existing base to replace one with ei141rc mains smoke alarm** A: Hi. As others have said, the existing base should work fine with the replacements. As far as I know (but I might be wrong!) the triggering of the second alarm if one goes off will only happen if an extra wire (interconnect) is already in place between the two devices. **Q: Does this fire alarm also detect carbon monoxide?** A: This fire alarm does NOT detect poisonous carbon monoxide. ## Frequently Bought Together - Aico EI141RC Mains Ionisation Smoke Alarm with 9V Battery Back-up - Duracell Plus 9V Batteries (Pack of 2) - Alkaline - 100% Life Guaranteed - Reliability For Everyday Devices - 0% Plastic Packaging - 5 Year Storage - 6LR61 MN1604 - Aico EI144e Heat Alarm Mains / 9V Battery Back Up, White --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/50434202-aico-ei141rc-mains-ionisation-smoke-alarm-with-9v-battery-back](https://www.desertcart.us/products/50434202-aico-ei141rc-mains-ionisation-smoke-alarm-with-9v-battery-back) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-30*
