So east to fit, slide out the old then slide in the new. No messing with retiring or changing base plates. Excellent, and quick delivery ### ⭐⭐⭐⭐⭐ Matches the existing base! *by S***N on 4 July 2026* Good quality ### ⭐⭐⭐⭐ Good replacements for older models *by T***D on 14 September 2022* Very easy to swap out older models for the new ones, a bit pricey when you have 8 to replace plus very wasteful on back plates that are thrown away. They look better than the older models however how good are they when a fire breaks out I do not know. The old ionising alarms gave false alarms where these do not but do they give you enough time to vacate the building? The other down side is replacing the battery after 5 years when the life of the unit is ten. ## Frequently Bought Together - Aico Ei146e Optical Smoke Alarm AC mains power supply and 9V alkaline battery back-up. - Aico EI144e Heat Alarm Mains / 9V Battery Back Up, White - Aico EI146e Set of 2 Mains Hard Wired Smoke Alarms with 9V Battery Back Up , White --- ## 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.jp/products/448317316-aico-ei146e-optical-smoke-alarm-ac-mains-power-supply-9v](https://www.desertcart.jp/products/448317316-aico-ei146e-optical-smoke-alarm-ac-mains-power-supply-9v) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-15*
