DAHUA smart smoke detector DHI-HY-SA2FA

Smart WiFi smoke detector with advanced split-spectrum technology for reliable smoke detection.

The modern smoke detector uses a photoelectric sensor with innovative split-spectrum technology, which ensures fast response and high sensitivity with minimal false alarms. The device continuously monitors the concentration of smoke in the room and immediately activates a visual and audible alarm with a volume of 85 dB at a distance of 3 meters when the threshold is reached.

Thanks to WiFi connectivity at a frequency of 2.4 GHz, the detector can send push notifications directly to your mobile phone, allowing immediate information about smoke detection even in your absence. The detector is suitable for use in residential areas such as villas, apartments, student dormitories, reading rooms, living rooms, bedrooms and hallways.

Intelligent status indication
The detector is equipped with colored LED indicators that provide clear information about the current status. In standby mode, the green LED flashes once per minute, in alarm mode the red LED flashes once per second, and in case of a fault or low battery, the red LED flashes once per minute.

Mute function
The integrated silence function allows the alarm to be temporarily silenced for approximately 12 minutes, which is useful when cooking or other activities that may cause an unwanted alarm.

Easy installation and maintenance
The detector is designed for ceiling mounting and, thanks to its compact dimensions, fits into any interior. The replaceable CR123A lithium battery ensures reliable operation without the need for a power connection.
