Product details of Gas leakage alarm sensor for fire safety
The gas leakage alarm is suitable for the place where natural gas exists. It Can detect and alarm the burning, explosion, poisoning caused by gas leakage. This product has the characteristic of high sensitivity , high stability, multi-gas detectable, smallcubage, easy to install and can use backup battery. Basic Function When the flammable gas density reaches to response setting value of density in its surrounding environment, the alarm can give out alarm signal of sound, light and networking. In the alarm state, the ambient concentration of combustible gas down to the rated value, the alarm can be automatically restored to normal monitoring state. It has red, yellow, green three state indicator lights and one built-in buzzer, show the following three kinds of states separately: 1. Green indicator lights up, the power supply operates normally, and in the state of monitoring; 2. Yellow indicator lights up with the sound of the buzzer, alarm faults(mainly on sensor); 3. Red indicator lights up, with the buzzer noise and networking output, indicate the alarm is in alarm state. Green indicator turn off, yellow indicator flash one time every 30 seconds, means 220VAC power off and using 9V backup battery(when battery voltage lower than 8.2V it will alarm, yellow indicator flash and buzzer sound) Installation 1. Design for wall mounted, please install the product where’s up from the leakage of the natural gas 2. When install alarm, use 2pcs of self tapping screw & expansion pipes from installation package, fix the mounting bracket on the wall, and then install the detector onto the bracket (note to align detector in the mouth of bracket chuck, and rotate enough to the right place) 3. Connect power, self-testing is over, then press the test key, the detector gives out“Di Di” buzzing, the red light flashes and emits radio frequency, installation is finished. Notes: a. The alarm can’t be installed too close to above the gas source, should 2m min. above to avoid faulty alarm even at normal use. b. The alarm can’t be held at bathroom or moister place. C. Alarm’s forbidden with paint, alcohol, should isolate the alarm immediately if two kinds of gas exist in the room, lest damage the sensor.
