Frequently Asked Questions (FAQ)
What technology does this device use to detect gas leaks?
This device utilizes internationally advanced TDLAS (Tunable Diode Laser Absorption Spectroscopy) technology. It is specifically designed for household gas safety by detecting only methane molecules.
Will cooking fumes or alcohol cause false alarms?
No. The TDLAS tunable laser spectroscopy technology ensures exceptional resistance to common kitchen interfering gases such as cooking fumes and alcohol, eliminating false alarms and missed detections.
How long does the sensor last?
The laser sensor has a typical designed lifespan of up to five years. This far exceeds traditional sensors, significantly reducing ongoing maintenance and replacement costs.
What actions does the device take when a leak is detected?
Upon detecting a leak, the device emits a high-decibel audible and visual alarm, automatically activates an emergency shut-off solenoid valve via a DC 12V pulse signal to shut off the gas supply, and activates the exhaust fan via a passive switching signal to reduce gas concentration.
What is the response time of this gas detector?
The response time of the device is less than 20 seconds, allowing it to quickly identify hazards and save valuable time for emergency response.
Does the device support remote monitoring?
Yes. With an optional wireless transmission module, the device can connect to the company's IoT platform and solenoid valve controller, enabling remote monitoring and mobile alerts.
