## Summary description

The Ei Electronics Ei650 is a wireless optical detector powered by a 3V lithium battery. With a diameter of 11.5 cm and a height of 45 mm, it weighs 180 g.

Its compact design allows for easy installation in various locations, providing peace of mind in fire safety.

## Long description

The Ei Electronics Ei650 is an optical smoke alarm that uses the light-scatter principle to provide a prompt response to common domestic fire types. Powered by an internal non-replaceable 3V lithium cell that lasts for over 10 years, the Ei650 is supplied with a twist-on base and screw fixings for straightforward installation. The unit features an easy-to-use combined Test/Silence button, a red LED status indicator, a built-in 85 dB(A) sounder at 3 m, and a high-performance optical chamber with an integral insect screen to reduce false alarms.
Advantages
The sealed 10-year lithium cell eliminates the need for battery replacement and reduces the chance of the alarm being disabled. The tamperproof, twist-on base prevents battery drain during storage and simplifies commissioning. Automatic self-checks for battery and smoke chamber status, together with a clear LED heartbeat every 40 seconds, ensure ongoing reliability. The large Test/Silence button enables full horn testing and temporary silencing of nuisance alarms for 10 minutes.
Suitable for
Residential homes (bedrooms, hallways, living rooms)
Small apartments and flats
Installation where long-life maintenance-free detectors are preferred
Rooms where reduced false alarms are required due to the insect-screened optical chamber
