Smoke and gas detector for home is a smart combustible gas detector with microprocessor control. It will make a sound with the build-in siren when the gas leaking. The combustible gas alarm uses semiconductor sensor which is stable and reliable. It keeps the place safe from the threats of combustible gas. (Such as liquefied petroleum gas, natural gas, methane, etc.)

Features

Home smoke and gas detectors are equipped with high-reliability sensors to ensure accurate and stable detection performance.
Wall-mounted smoke and gas detectors provide sound and flash alarm systems, or optional human voice alarms to issue warning signals in time.
It can be equipped with solenoid valve outputs to automatically cut off the gas supply when danger is detected, increasing safety.
Smoke and gas detectors for home have the function of automatically detecting sensor failures, which can instantly identify and report sensor problems.
The combustible gas alarms can detect natural gas and liquefied petroleum gas (LPG), providing comprehensive gas monitoring protection.
It adopts SMT design, which improves the stability and durability of the equipment.

Tips: Operating instructions for home smoke and gas detector

With AC 90~240V power supply, the green LED flashes once a second for about 3 minutes continuously, that runs the inside sensor (warm-up state). After doing that the green LED lights, that means the detector comes into normal working state.
While detecting the gas leaking, the red LED flashes, the Buzzer sends out the alarm sound "Di Di", and output the network signal. If the detector is connected with valve, it will drive them to shut off the gas pipeline supply. The detector will resume to the detecting state after the gas dispersed.
The buzzer long beeps and the red LED ON means the inside sensor failure. Please cut off the power, and contact us.
If the detector runs disorderly, cut the power off and rerun again. If still in wrong, please contact us.
