DAHUA heat detector DHI-HY-HT10A

Autonomous heat detector designed for continuous temperature monitoring in environments unsuitable for smoke detectors.

The detector is equipped with a high-precision thermistor and an intelligent algorithm that triggers an alarm when a preset temperature of 54°C to 65°C is reached. It is ideal for smoky, dusty or humid environments where smoke detectors would cause false alarms - for example, kitchens with cooking fumes, attics, garages or boiler rooms with a high dust content.

Powered by a 10-year sealed battery , it provides continuous fire protection for a decade without the need for replacement. The detector samples temperature every 10 seconds and emits an 85 dB sound at a distance of 3 meters when alarmed.

Advanced LED signaling
The green LED flashes once per minute in standby mode, the red LED flashes once per second in alarm and twice per minute in fault mode, providing immediate visual information about the detector's status.

Reliable construction
The white plastic case made of PC material withstands normal wear and tear and ensures long-term functionality. The SMD construction of the printed circuit board increases the reliability of the electronics.

Certifications and standards
The detector complies with the European standard BS 5446-2:2003 and is CE certified, which guarantees safety and quality according to European standards.
