Main Features

Photoelectric Thermal Sensing Technology:

Employs advanced photoelectric thermal detection technology, reacting sensitively to temperature changes. An alarm is immediately triggered when the ambient temperature reaches the preset 58°C (136.4°F). RF433MHz Wireless Interconnection
Built-in wireless communication module, supporting multi-detector network linkage. When one detector alarms, all detectors in the system will simultaneously sound an alarm, achieving comprehensive early warning.

10-Year Long-Lasting Lithium Battery

Utilizes a high-quality DC3V lithium-thionyl chloride battery with a sealed design ensuring an ultra-long 10-year lifespan. Maintenance-free design, eliminating concerns about frequent battery replacements after installation.

Intelligent Function Design

Equipped with test and mute buttons for convenient periodic testing and device silencing. When the battery is low, the device will emit a clear low-battery warning sound, reminding you to take timely action.

Products that meet this standard undergo rigorous testing to ensure reliable alarm performance in the event of a fire, providing protection for your life and property.
BS5446 is a widely recognized fire detector safety standard in the UK and Europe, covering key indicators such as electrical safety, environmental adaptability, and alarm performance. This certification signifies that the product meets industry standards for quality, reliability, and safety.

Suitable Locations:

Residential Homes – Living rooms, bedrooms, kitchens, hallways, etc.
Commercial Locations – Offices, meeting rooms, small shops, restaurants
Service Industries – Hotel rooms, guesthouses, nursing homes, school dormitories
Special Areas – Garages, warehouses, equipment rooms, etc., areas with fire risk but unsuitable for smoke detectors

Installation Recommendations:

It is recommended to install at least one heat detector on each floor.
Prioritize installation in areas with higher fire risk, such as near the kitchen (but direct installation inside the kitchen is not recommended).
Install in the center of the ceiling, at least 30cm away from walls and light fixtures.
Avoid installation near vents, doors, windows, or other areas with strong airflow.
Regularly (monthly) check the device’s operational status using the test button.
