Review: So far so good - Bought lots of FireAngels over the years, always very pleased with them. The 10 year ones never last me 10 years though, more like 6 or 7, so this time I went for one with replaceable AA cells as they're dirt cheap (Alkaline GP brand, really good value for money, I've been buying those for years too). All fine on installation, popped straight into the old FireAngel ceiling mount that I'd installed for the previous one. However I thought I might have to send this one back as we had a nuisance alarm from it on around the 3rd night after installation at 3am, grrrrrrrrrr! I pulled the batteries out as there was clearly no cause for alarm, and reinstalled again the next day and it's been fine since, so, so far so good, hopefully it has "bedded-in" now :o) UPDATED Dec2023 - That initial glitch didn't repeat itself, so I've bought another one to replace another 10-yr one (as usual only 7 year!) now which is fine so far :o) They fit straight into the existing mounting plates of my previous generation FireAngels which is super! UPDATE Oct2024 - AA cells still above 1.5V each after about a year, so it looks like AAs will probably last about 2 years which sounds fine. No more nuisance alarms after that first glitch so I'm ordering more as my last remaining 10year alarm has actually reached 10 years and needs binning. Review: Great wouldn’t have a different brand smoke detector - Average life of 3 years even though they say 10 year battery so always best to buy a twin pack. Easy to fit base plate seems to be universal to fire angel models. The brand the fire service fits. ## Features - SMOKE DETECTORS FOR HOME: The optical smoke alarm’s sensing chamber 'sees' smoke as it enters, enabling a fast response to slow-burning fires with thick white smoke. - FEWER NUISANCE ALARMS: The advanced optical sensor ensures the fire alarm is less prone to false alerts from cooking fumes. Avoid placing near bathrooms or kitchens. - EASY TO FIT: Attach the removable baseplate to the ceiling. Insert the batteries, and push and twist the alarm to secure. The baseplate is identical to FireAngel smoke alarms ST-622, ST-620, and ST-750, making replacements quick and easy. - SAFETY ASSURED: The FA6615 Fire Angel smoke alarm holds CE and UKCA marks and is certified to EN 14604:2005+AC:2008. It is suitable for domestic properties and leisure accommodation vehicles and includes a 5-year warranty. - FIREANGEL HOME SAFETY: We offer a wide range of safety products designed to protect you and your family. Choose from smart and wireless devices, as well as standard smoke, heat, and carbon monoxide alarms. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09WB3FQNK | | Alarm | Smoke Alarm | | Best Sellers Rank | 533 in DIY & Tools ( See Top 100 in DIY & Tools ) 4 in Smoke Alarms | | Brand | Fireangel | | Colour | White | | Customer Reviews | 4.5 out of 5 stars 1,199 Reviews | | Included Components | 1 x Instruction Manual, 2 x Baseplate, 2 x Optical Smoke Alarms, 4 x AA Batteries | | Item Dimensions D x W x H | 10D x 10W x 10H millimetres | | Item Highlight | 2-Pack, Early Smoke Alarm Detector with 5-Year Replaceable Batteries, Fire Alarms for Home | | Item Type Name | Smoke Alarm | | Item Weight | 185 Grams | | Item weight | 185 Grams | | Manufacturer | FireAngel | | Manufacturer Warranty Description | 5 year manufacturer's warranty. | | Material | Plastic | | Model Number | FA6615-R-T2 | | Number of Items | 2 | | Part Number | FA6615-R-T2 | | Power source | Battery Powered | | Product Style | 5 Year Replaceable Battery (Better) | | Product dimensions | 10D x 10W x 10H millimetres | | Sensor Type | Photoelectric | | Style | 5 Year Replaceable Battery (Better) | | UPC | 816317006341 | | Unit Count | 2.0 count | ## Product Details - **Alarm:** Smoke Alarm - **Brand:** Fireangel - **Colour:** White - **Item weight:** 185 Grams - **Material:** Plastic - **Power source:** Battery Powered - **Product dimensions:** 10D x 10W x 10H millimetres - **Sensor type:** Photoelectric - **Style:** 5 Year Replaceable Battery (Better) - **Unit count:** 2.0 count ## Images ![– FireAngel FA6615-R Optical 10-Year Fire/Smoke Alarms for Home | 2-Pack, Early Smoke Alarm Detector with 5-Year Replaceable Batteries, Fire Alarms for Home - Image 1](https://m.media-amazon.com/images/I/51iqUjgQxSL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: Do these fire alarms activate eachother when one goes off? Need one inside sound proof room and one outside thanks** A: Good Morning, These are standalone alarms so they will not link in with any other unit. If you are looking for units that will trigger each other in the even of a fire, then our Pro Connected range will be more suited. Many Thanks, Gemma **Q: Are these suitable for the new Scottish legislation** A: Good Morning The TST-625R alarm is a standalone unit and therefore cannot be interlinked with any other product. If you are looking for units which can be interlinked with each other then I would recommend the FireAngel Pro Connected range. Many Thanks Gemma **Q: Will this fit the baseplate for the old si-601?** A: Yes, this unit will fit onto your existing base plate. Many Thanks Gemma **Q: How loud is the alarm in term of db ?** A: DB unknown but very loud and as loud as any other alarm I've had over the last 40 years. ## Customer Reviews ### ⭐⭐⭐⭐⭐ So far so good *by D***K on 28 October 2023* Bought lots of FireAngels over the years, always very pleased with them.

Easy to fit base plate seems to be universal to fire angel models. The brand the fire service fits. ### ⭐⭐⭐⭐ Good but doesn't like rechargeable batteries *by N***T on 14 January 2025* Bought this version to avoid the rectangular batteries so that we could use rechargeable ones. Sadly the rechargeable Amazon AAs started the alarm beeping after only a couple of days. Guess this is because of the possible lower voltage of rechargeable ones, but was a shame as now need to buy ones to discard every so often. Unsure as to how long the provided energizer batteries will last. Hopefully a while. ## Frequently Bought Together - FireAngel Optical Smoke Alarm with 5 Year Replaceable Batteries, FA6615-R-T2 (ST-625 replacement, new gen) - Twin Pack - 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.jp/products/432041137-fireangel-fa6615-r-optical-10-year-fire-smoke-alarms-home](https://www.desertcart.jp/products/432041137-fireangel-fa6615-r-optical-10-year-fire-smoke-alarms-home) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-07*
