433MHZ WIRELESS GAS LEAKAGE DETECTOR LPG CO NATURAL GAS IN SOUTH AFRICA

Description: The gas leakage alarm is suitable for the place where coal gas/natural gas/liquid petroleum gas exists.This product has the characteristic of high sensitivity, high stability, multi-gas detectable, small cubage, easy to install and can use backup battery. Features: Alarm density reaches: Coal gas: 2000ppm+/- 30%, natural gas: 2000ppm+/-30%, Liquid petroleum gas: 5000ppm+/-30% Working mode: independent & compatible mode Siren:>90db Specification: Working voltage: AC 220V Power consumption: static≤10 mA alarm≤15 mA Alarm Range: natural gas 3%~15%LEL Response time: Alarm sound: >75Db(right ahead 1m) Installation style: wall mounted Gas sensor: life span 3 years Humidity Range: 10%~95% RH Air pressure: 86~106Kpa Emission frequency:433 MHZ Oscillation resistance:330k Code form:1527 Emission distance: ≥100m (in open air) Backup battery: 9V alkaline Coding way: button alarm coding(After self-testing, press the button to emit 433MHZ signal) How does it work? 1.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. 2.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. 3.It has red, yellow, green three state indicator lights and one built-in buzzer, show the following three kinds of states separately: Green indicator lights up, the power supply operates normally, and in the state of monitoring; Yellow indicator lights up with the sound of the buzzer, alarm faults(mainly on sensor); 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 220V AC power off and using 9V backup battery(when battery voltage lower than 8.2V it will alarm, yellow indicator flash and buzzer sound) Package includeds: 1 x Gas Detector 1 x User Manual Details pictures:
