## Summary description

DAHUA HY-HT5MA is a heat detector designed to signal fire-related temperature rise using a fixed-temperature thermal sensing element. Intended for use in fire detection systems, it provides reliable alarm activation when ambient temperature reaches the detector's threshold. Suitable for indoor protection in commercial and residential installations where smoke detectors are not applicable.

## Long description

The DAHUA HY-HT5MA is a fixed-temperature heat detector designed to detect a rise in ambient temperature and generate an alarm when a preset threshold is reached. Intended for integration into fire detection systems, this detector uses a thermal sensing element calibrated to trigger at its fixed activation temperature. It is suitable for indoor environments where smoke-based detection is unsuitable, offering a straightforward method to protect spaces against open heat sources and rapid temperature increases.
Advantages
The DAHUA HY-HT5MA delivers reliable activation based on a fixed-temperature thermal sensing element, minimizing false alarms in environments with dust, steam, or fumes where smoke detectors can be impractical. Its design is compatible with standard fire detection loops and control panels, allowing easy integration into existing systems. The detector’s operation focuses on temperature thresholds rather than smoke concentration, providing a complementary detection method in specific installation scenarios.
Suitable for (tasks / use cases)
 Indoor protection of commercial premises such as kitchens, boiler rooms and utility spaces where smoke detectors may false-alarm.
 Residential areas where early detection of rapid temperature rise is required but smoke detectors are not suitable.
 Industrial or storage rooms with dust, vapors or airborne particles that can affect smoke sensors.
 Integration into conventional fire detection systems as a temperature-triggered device.
When it may not be suitable
The HY-HT5MA is not intended to detect smoldering fires that produce smoke without a significant temperature rise; in such cases, smoke detectors or multi-criteria detectors are more appropriate. It also may not be suitable for environments where gradual temperature increases below the activation threshold represent a hazard, as the fixed-temperature mechanism triggers only when the set point is reached.
Key specifications
 Detection principle: fixed-temperature thermal element
 Intended use: indoor fire detection
 Mounting: ceiling or wall mount compatible with standard detector bases
 Trigger behaviour: activates when ambient temperature reaches preset threshold
 Compatibility: designed for integration with compatible fire alarm control panels
How to use
Install the DAHUA HY-HT5MA according to the fire system designer’s plan and the manufacturer’s mounting instructions, typically on a ceiling or high on a wall where temperature rise will be detected promptly. Connect the detector to the fire alarm loop or compatible control panel following standard wiring practices and verify correct electrical connections before powering the system. After installation, perform commissioning tests to confirm the detector signals the control panel at the expected activation conditions and carry out routine inspection and maintenance as required by local regulations.
What to consider before purchase
 Required activation temperature and whether fixed-temperature detection meets the protection requirements.
 Compatibility with your existing fire alarm control panel and detector base type.
 Environmental conditions at the installation site (steam, dust, fumes) and whether a heat detector is preferable to a smoke detector.
 Installation height and location to ensure reliable temperature sensing.
Usage recommendations
Choose mounting locations away from localized heat sources (vents, lighting, machinery) that could cause nuisance alarms. Use the HY-HT5MA alongside smoke or multi-criteria detectors where comprehensive detection is required. Follow local fire codes for spacing, testing intervals and maintenance to ensure long-term reliability.
