Specification :

Feature:

1, Independent mode: it works as wireless auto gas leakage alarm.
2, Compatible mode: it is compatible with our burglar alarm system.
3, Self-detector and automatically give an alarm warning to users. When it works with our burglar alarm, with LED indicated, it sends a wireless signal to alarm host if detecting density with time reaches the limit figure required as below and then it alarms and the alarm host auto-dials the pre-setting telephone or mobile phone
4, It is strictly compliance with quality system, It can be effective to prevent fire by flammable gas, such as coal gas, liquid petroleum gas and natural gas. And monitor automatically
5. Widely use for house, coal station, colliery and so on

Characteristics
1, Power supply: AC220V or DC 12V.
2, Static consume: 1.3W
3, Alarm 1.7W
4, Working environmenttemperature
10ºC^45ºC Humidity: 30%~90%
5, Alarm density: Coal gas: 2000ppm+/- 30%, Liquid petroleum gas: 5000ppm+/-30%, natural gas: 2000ppm+/-30%
6, Responsible time: less than 2 seconds
7, Alarm output: frequent on or off signal, control exhaust fan, electrical magnetic valve signal

Installation
According to specific gravity of natural gas to install gas leakage alarm. Natural gas and coal gas: its specific gravity is lighter than air, so it suspends on the ceiling. Therefore, the alarm should be installed in the area that is less 0.3~1.2 meter than the ceiling and within radii 1.5 meter far from gas leakage. Liquid petroleum gas: its specific gravity is heavier than air, so it sinks down on the bottom. Therefore, the alarm should be installed in the area that is 0.3~1.2 meter far from ground and within radii 1.5 meter far from gas leakage.
