10-year sealed battery smoke detector AE6620-FRR

Thanks to optical detection technology, smoke is quickly detected when it enters the alarm chamber, allowing for a rapid response to slow-burning fires.

The alarm comes with a sealed, irreplaceable battery that will last the entire lifespan of the alarm (it is recommended to replace smoke detectors every 10 years).

Equipped with a silent test function, meaning you are less likely to wake loved ones or disturb neighbors when testing your alarms.

Give yourself time to replace your alarm by silencing low battery warnings for up to 8 hours using the easy sleep function.

FireAngel alarms are rigorously tested to ensure unparalleled quality and longevity and come with a 5-year manufacturer's warranty for peace of mind.

A perfect replacement for the FireAngel ST-622, ST-620 and ST-750 models, this alarm fits onto the existing bracket or can be easily installed using the included bracket and 2 screws.
