Certified to UK and European safety standards, it offers easy installation and a 5-year warranty, making it the smart choice for modern home safety. ## Description Designed as a replacement for the Fire Angel ST-622 / ST-620 smoke alarms, the FireAngel FA6620 Optical Smoke Alarm (available as a twin pack) is fitted with a 10-year lifetime sealed battery and equipped with an optical sensing chamber, providing a fast response to slow-burning fires. ENHANCED SENSING The optical smoke sensing chamber works by 'seeing' smoke as it enters the alarm—making it perfect for slow-burning fires with thick white smoke and less prone to false alerts from cooking fumes. It can still be subject to nuisance false alarms from steam and should not be placed near bathrooms or kitchens. SLEEP EASY If a low battery alert occurs at night, you can silence the smoke detector for 8 hours by pressing the test button. The alarm will be muted, but the red LED will continue to flash. The alarm will still detect smoke during Sleep Easy mode. Replace within 30 days. TEST/SILENCE To test your device, press the large test button for 5 seconds. A loud, high-pitched sound will verify the alarm is functioning correctly. During a known false alarm, press the test button for 5 seconds to temporarily silence the alarm for 8 minutes. Review: Good - Good quality Review: Thoughtful design - Ordered in the morning, arrived on the same evening. We already had Fire Angel sealed units up, fitted by the fire brigade 8 years ago. The one at the top of the stairs started giving occasional false alarms. I put this down to occasionally getting steam from the adjacent bathroom. Not a problem after 8 years. I bought the replacements and was delighted to see that despite the design changing over time, the wall plate they fit to has remained the same. Simple installation, quarter turn to get the old one off, quarter turn to put the new one on. I wouldn’t buy any other type ## Features - SMOKE DETECTORS FOR HOME: The optical smoke alarm makes protecting your home simple. Its optical sensing chamber 'sees' smoke as it enters the alarm, providing a fast response to slow burning fires with thick white smoke. - FEWER NUISANCE ALARMS: The advanced optical sensor ensures the FireAngel smoke alarm is less prone to false alerts from cooking fumes.

We already had Fire Angel sealed units up, fitted by the fire brigade 8 years ago. The one at the top of the stairs started giving occasional false alarms. I put this down to occasionally getting steam from the adjacent bathroom. Not a problem after 8 years.

I wouldn’t buy any other type ### ⭐⭐⭐⭐⭐ Excellent smoke alarms - FireAngel quality you can trust *by M***H on 15 September 2025* I'm a loyal FireAngel customer and these smoke alarms maintain the brand's excellent reputation. The quality and reliability are second to none, which is exactly what you want from a safety device. Installation is straightforward and they're up and running quickly. The optical sensor technology works perfectly - sensitive enough to detect real smoke threats but smart enough to ignore false alarms like vaping, which is a huge advantage over cheaper detectors. The alarm tone strikes the perfect balance - loud enough to wake you and alert the household, but not so overwhelming that it's painful. There's no annoying constant beeping during normal operation either. The 10-year battery life is fantastic - set and forget peace of mind. The white finish looks clean and unobtrusive on the ceiling. Pro tip: pair these with magnetic mounting pads (as mentioned in my other reviews) for incredibly easy installation without drilling. These are premium smoke alarms that justify the price with superior performance and reliability. When it comes to fire safety, I wouldn't trust anything else. Highly recommended for anyone serious about home safety. ## Frequently Bought Together - FireAngel Optical Smoke Alarm 2-Pack - 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.sn/products/670372067-fa6620-optical-battery-powered-fire-smoke-alarms-for-home](https://www.desertcart.sn/products/670372067-fa6620-optical-battery-powered-fire-smoke-alarms-for-home) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-09-29*
