Carbon Monoxide Alarm with high stability, hereinafter called detector. It protects your family from the two deadly threats: carbon monoxide and other harmful gases such as natural gas-methane, The detector is with LCD digital screen continuously displays the level of natural gas (if any) the alarm is sensing and so as the carbon monoxide. The detector adopts MCU processing technology with a long life, convenient installation and high reliability. Besides, it completes with a special circuit that control the advanced semiconductor sensor and electro-chemical CO sensors efficiency level, and signals any possible fault. HD1100D alarm has 4 status LED (power, warm up, fault and alarm indications) and The large digital display are easy to read, informing you of alarm working status, gas levels and the type of gas being detected. The customers requirement for carbon monoxide sensor and before 7%LEL for natural gas, and it can activate solenoid valves, sirens and any other signal or alarm handling device if any, by means of the built in relay.
