Fire Safety
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. The FireAngel FA6620-R Optical Smoke Alarm has been designed to make protecting your home simple, with an easy installation process, fewer false alarms, and rigorous testing.
OPTICAL SENSOR: The FA6620’s optical smoke-sensing chamber works by ‘seeing’ smoke as it enters the alarm, making it ideal for slow-burning fires that produce thick, white smoke. Whilst it is less prone to false alarms from cooking fumes, it can still be triggered by steam. Not suitable for kitchens or bathrooms.SEALED-FOR-LIFE BATTERY: The FA6620 smoke detector has a 10-year, tamper-proof battery that will last the lifetime of the alarm. A red operational LED will flash, and an audible beep will alert you when the device needs replacing.FOR DOMESTIC PREMISES ONLY: Suitable for domestic premises, including leisure accommodation vehicles (mobile homes and caravans). Not suitable for commercial properties.
Designed to replace the ST-622 and ST-620 smoke alarms, the baseplate is identical to the ST-622, making replacements quick and easy.
FireAngel: Smarter solutions for safer homes.
Early Warning System Smoke alarms provide an essential early warning system for potential house fires. The FA6620 smoke alarm holds both CE and UKCA marks, has been rigorously third-party tested, and is certified to BS EN 14604:2005+AC:2008.
Sleep Easy To test your device, press the large test button. A loud, high-pitched sound will verify that the alarm is functioning correctly. In a known false alarm, press and hold the test button to temporarily silence the alarm for 10 minutes. If a low battery alert occurs at night, you can silence the smoke detector for 8 hours by pressing the test button.
Safety Guidelines The FA6620 is suitable for the landing, hallway, bedroom, living room and dining room. Smoke alarms should be sited at least 300 mm from light fittings and walls, and ideally as central as possible in the room. Avoid installing near kitchens or bathrooms.
