Autonomous 220V Natural Gas and Coal Leak Detector with Alarm and NC NO Relay Output

General description Standalone natural gas leak detector operating on AC 220 V, equipped with NC and NO relay output. This device is designed to detect the presence of coal gas and natural gas, which have a density lower than that of air, and should be installed close to the gas source, within 2.5 m. Technical specifications Power supply voltage: AC 220 V Output type: NC and NO relay Detection density: 6% LEL Installation Install near the gas source, within 2.5 m. Make sure the power and signal cables are properly connected. Do not install outdoors or in damp locations. Avoid areas of intense air circulation (ventilation, doors). Do not isolate the detector from the gas source. Use After installation, turn on the device to start preheating.The red LED light flashes once and the speaker emits a sound to indicate startup. In monitoring state, press S1 button to test operation. If the gas density reaches 6% LEL, the LED indicator turns red and emits an alarm beep. To reset after an alarm, resolve the emergency situation and return the detector to normal state. Other Information Test the detector regularly by filling a hole with gas for at least 5 seconds. Clean the detector regularly to maintain its sensitivity. The warranty will be voided if the product is opened by the user.
