Dahua HY-SA40A-R8

The Dahua HY-SA40A-R8 is a wireless, interconnected smoke alarm designed for comprehensive fire detection in multi-room buildings. It uses photoelectric sensing technology to detect slow-burning, smoldering fires more efficiently than traditional ionization sensors.

Its wireless interconnection feature allows multiple units to communicate with each other—when one alarm detects smoke, all connected alarms activate, ensuring everyone in the building is alerted simultaneously. This feature is crucial for larger homes, multi-story buildings, offices, and commercial spaces where early evacuation is necessary.

The Dahua HY-SA40A-R8 is powered by a long-lasting replaceable battery, making it wire-free and easy to install without the need for electrical wiring.
