High Quality Wired Gas Leakage Sensor with Solenoid Valve

Gas Leakage Detector: Self-detecting, no wrong report, and reliability. Can be used independently to alarm, or can be used with the alarm system to send the sign to the control panel if detecting density with time reaches the limit figure required as below and then it alarms and the alarm control panel auto-dials the presetting telephone or mobile phone . It is designed for a wide range of residential where reliable gas leakage detection is required.Achieving superior gas detection sensitivity levels, the ZDD-305G provides early warning of gas leakage. When gas is detected, the ZDD-305G issues both sound and transmit alarms. The ZDD-305G transmits supervisory reports to the wireless control panel or receiver at regular intervals - ensuring system integrity and functionality at all times.It is strictly compliance with international standard and quality system, it can be effective to prevent fire by flammable gas. Widely use for house, coal station, colliery and so on.- Wired/ Independent use optionalFeature:
- Providing early warning of developing gas leakage when gas density is detected to reach limit.
- Self-detecting, no wrong report, and reliability.
- Flexible signal output type: Independently use, Wired, wireless is optional.
- Easy to install with mounting hardware included
- photoelectric chamber for early detection from all directions
- Sounds aloud(85DB) when it detects a dangerous level of gas.
- Meet GB15322/EN50914/UL1484 standards.
