LOREX LR-DG220 Domestic Gas Alarm
Overview
The LOREX LR-DG220 is a crucial safety device for homes and similar environments, designed to detect explosive gases in the air, including natural gas (CH4) and LPG. In the event of hazardous gas concentrations, the device provides audible alerts via buzzer and visual warnings via LED. It also supports an optional relay output for connecting external devices such as solenoid valves or sirens.
Key Features
- Advanced Detection: responsive to explosive gases like natural gas and LPG.
- Audible & Visual Alerts: loud buzzer and bright LED indicator for immediate warning.
- LEL Sensitivity: natural gas at 0.5% (5000 ppm) and LPG at 0.3% (3000 ppm).
- Relay Output (Optional): supports external safety devices (valve/siren integration).
Installation & Operation
- Power Up: connect to power source. Green LED indicates power on.
- Calibration: 60-second calibration at first power-up or after interruptions.
- Ready State: after calibration, the unit begins monitoring gas levels.
- Alarm Activation: red LED + buzzer when gas reaches LEL; continues until safe.
- Returning to Normal: returns to monitoring mode when levels fall below LEL.
- Fault Indicator: yellow LED indicates sensor issue or malfunction.
