Product Description
The ANWETECH AT-S225 is a standalone dual-power photoelectric smoke detector developed for effective smoke detection in homes and similar indoor applications. It uses photoelectric smoke sensing technology to detect smoke at the early stage of fire and provide reliable sound alarm warning to help protect people and property.
Unlike standard battery-only models, the AT-S225 supports both DC 9V battery power and AC 110V/220V power supply, giving users greater flexibility for different installation environments. This dual-power design makes the detector suitable for projects where stable mains power is preferred while still allowing battery-powered operation.
The detector is suitable for bedrooms, hallways, stairways, attics, basements and locations near electrical equipment. It is easy to install, simple to test and suitable for houses, apartments, residential buildings and light commercial areas that require dependable standalone smoke alarm protection.
