• 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 and LPG (Liquefied Petroleum Gas). In the event of detecting hazardous gas concentrations, the device provides audible alerts with its buzzer and visual warnings with its LED light. It also features a relay output for connecting to other devices like solenoid valves or sirens that are activated during an alarm.

Key Features:

• Advanced Detection: Responsive to explosive gases like natural gas and LPG.
• Audible and Visual Alerts: Loud buzzer and bright LED indicator for immediate notification.
• Lower Explosive Limit (LEL) Sensitivity: Detects gas concentrations below the point at which they can ignite or explode. Natural gas detection at 0.5% or 5000 ppm, and LPG detection at 0.3% or 3000 ppm.
• Relay Output: Connects to external devices for enhanced safety measures. (Optional)

Installation and Operation:

1. Power Up: Connect the device to a power source. A green light indicates power is on.
2. Calibration: The device undergoes a 60-second calibration upon initial power-up or after power interruptions. During this time, it does not detect gas or conduct tests.
3. Ready State: After calibration, the device is prepared to monitor gas levels.
4. Alarm Activation: If gas reaches the LEL, the red LED light and buzzer are triggered, continuing until gas levels fall below the LEL.
5. Returning to Normal: The device reverts to its monitoring state once gas levels are safe.
6. Fault Indicator: A yellow LED light signifies sensor issues or malfunctions. Contact technical support in such cases.
