Its advanced optical sensor minimizes false alarms, while the twist-fit baseplate allows quick upgrades from previous FireAngel models. Certified to British safety standards and backed by a 5-year warranty, it offers reliable, low-maintenance fire detection tailored for modern households. ## Description From the manufacturer Fire Safety The FireAngel FA6615-R optical smoke alarm is designed to make home protection simple, with easy installation, fewer nuisance alarms, and rigorous testing. OPTICAL SENSOR: The FA6615-R’s optical smoke sensing chamber ‘sees’ smoke as it enters the alarm, reducing the likelihood of false alarms. It is ideal for slow-burning fires that produce thick white smoke. 5-YEAR BATTERY : Each smoke detector has a 10-year sensor life and comes with 2 x 5-year replaceable batteries. When the batteries are low, the device will alert you with a 'chirp,' and the red operational LED will flash once every 40 seconds. Replace the batteries ASAP. EASY REPLACEMENTS: The FA6615-R’s baseplate is identical to those of the ST-622, ST-620, and ST-750 smoke alarm models, eliminating the need to install a new baseplate. Simply remove the old smoke alarm (whether it’s an ST-622, ST-620, or ST-750), insert the batteries into your new FA6615-R alarm, and twist to secure it to the existing baseplate. SUITABLE FOR DOMESTIC PREMISES ONLY: Suitable for domestic properties, including leisure accommodation vehicles (LAV). Not suitable for commercial properties. At FireAngel, we're dedicated to protecting and improving our customers’ lives by creating innovative, cutting-edge fire safety technology that is both practical and accessible. FireAngel: Smarter solutions for safer homes. Third-Party Tested Smoke alarms provide an essential early warning system for house fires. The FA6615-R smoke alarm has undergone comprehensive third-party testing by independent parties to ensure its quality and longevity. The FA6615-R meets British Safety Standard EN 14604:2005+AC:2008 Sleep Easy To test the device, press the large test button. A loud, high-pitched sound will confirm that the alarm is functioning correctly. If a low battery alert occurs at night, you can activate Sleep Easy mode to silence the smoke detector for 8 hours by pressing the test button. Safety Guidelines The FA6615-R smoke alarm is suitable for the landing, hallway, bedroom, living room, and dining room. Smoke alarms should be installed at least 300 mm away from light fittings and walls, and ideally positioned as centrally as possible in the room. Safety First What should I do if my smoke alarm sounds? In the event of a smoke alarm sounding STAY CALM: Don’t panic, take immediate action to ensure your own safety and that of others. CHECK FOR SMOKE OR FIRE: Look for visible smoke or flames. If you see either, evacuate immediately. EVACUATE: Leave the premises as quickly as possible using the nearest exit. Do not use lifts. Take the stairs. Ensure everyone is accounted for and exits safely. CLOSE THE DOORS: Close doors behind you as you leave to slow the spread of smoke. CALL 999: Once outside, call the emergency services, providing the operator with your location and any details about the fire. DO NOT RE-ENTER: Do not go back into the building until it has been declared safe by the fire service. About Us We pride ourselves on product reliability and quality.

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. ## 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.sn/products/432041137-fa6615-r-optical-10-year-fire-smoke-alarms-for-home](https://www.desertcart.sn/products/432041137-fa6615-r-optical-10-year-fire-smoke-alarms-for-home) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-16*
