DAHUA heat detector DHI-HY-HT10A-R8

Wireless heat detector with intelligent algorithm for reliable fire detection in demanding environments.

The advanced heat detector is specially designed to continuously monitor abnormal temperatures using a high-precision thermistor . It triggers an alarm when a preset temperature is reached within the range of 54°C to 65°C according to the Class A1 standard. It is ideal for smoky, dusty or humid environments where smoke detectors could cause false alarms - for example, kitchens with cooking fumes, attics, garages or boiler rooms.

The detector is equipped with a 10-year non-replaceable battery and provides continuous protection for a decade. Wireless connectivity allows you to create a network of up to 24 devices , which, when detecting a fire, will trigger an alarm simultaneously on all connected units within a range of up to 1000 meters .

Advanced LED signaling
The green LED flashes once per minute in standby mode, the red LED flashes once per second in alarm and once per minute in fault mode, allowing easy identification of the device status at a glance.

Smart mute and test
The 9-minute mute function can be activated by the central button or IR remote control. The built-in test function allows regular functionality checks without the need for exposure to high temperatures.

Robust construction
The white PC+ABS housing withstands operating temperatures of -10°C to +55°C at humidity up to 95% RH. The SMD electronics design ensures high reliability and long service life.
