Any unit from our FireAngel Pro range will be compliant though. Many Thanks Gemma **Q: Hello, Can this be affixed to the ceiling using magnets or heavy duty velcro strips?** A: Yes I think you could use magnets or Velcro strips but i used small Rawl plugs into plaster board. Simples. **Q: Can this be used to replace the discontinued model Deta 1151?** A: We used it to replace an expired and discontinued fire angel model in a caravan ,as we didn’t want more holes drilled in the ceiling. I am sorry I don’t know if it was originally a Deta 1151 but all we had to do was use the original base and screw the new top on. Hope it helps. **Q: I’ve been told I need to fit a heat alarm that will link with fire alarm; is this possible with this product?** A: No ## Frequently Bought Together - FireAngel Optical Smoke Alarm - FA6620 10-Year Battery Smoke Alarms for Home with Test/Silence Button - Replacement for FireAngel ST-622/ST-620 - Early Smoke Detector Fire Alarm - White - FireAngel Carbon Monoxide Alarm and Detector - FA6813 10-Year Sensor Life CO Alarm for Home with AA Batteries - Travel, Portable Carbon Monoxide Detector - CO Detector Monitor with Test Button - FireAngel Heat Alarm with 10 Year Sealed For Life Battery, FA6720-R (HT-630 replacement, new gen), 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.com.ar/products/419152260-fa6620-optical-smoke-alarm](https://www.desertcart.com.ar/products/419152260-fa6620-optical-smoke-alarm) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-10-06*
