Product Description
The ANWETECH AT-S227 is a wireless photoelectric smoke detector based on infrared photo-scattering technology. It uses a professional ultra-low power microprocessor together with a precision photoelectric sensor to monitor smoke concentration and provide reliable early warning of fire. The detector is designed for stable operation, low power consumption, durable construction and easy installation.
This model supports wireless interconnection, allowing paired detectors to trigger each other during alarm or test mode. When one detector goes into alarm, other interconnected units can sound within seconds, helping improve fire warning coverage in larger homes, apartments or multi-room spaces. The device also supports mute mode, self-test, fault alarm and module communication fault indication.
AT-S227 uses 1 × 3V CR123A lithium battery for the detector and 1 × 3V CR17505 lithium battery for the wireless module. With EN14604 compliance, 868.317 MHz wireless signal and a recommended replacement date of 10 years, it is suitable for industrial parks, residential areas, apartments, homes and similar indoor projects where wireless smoke alarm interconnection is required.
