Alecto SD510 Optical Smoke Detector with 5-Year Built-in Battery

The Alecto SD510 is a photoelectric smoke detector engineered for reliable fire safety in residential spaces. Its sealed 5-year lithium battery eliminates the need for battery replacements, ensuring continuous protection with zero maintenance. With an 85 dB alarm and EN 14604 certification, it delivers prompt alerts when smoke is detected.

Advantages

The optical sensor responds quickly to smoldering fires, which are common in homes. The built-in battery lasts the entire lifespan of the device, so you never have to worry about dead batteries. A test button and low-battery warning keep you informed, while the hush function temporarily silences nuisance alarms. The white ABS housing blends seamlessly into any ceiling.
