The ceiling gas alarm uses a high-quality gas sensor. The microprocessor combined with the precision temperature sensor can intelligently compensate for the drift of the gas sensor. It has a wide range of environmental adaptability, stable operation, no need for debugging, and uses a suction Top-mounted, easy to install and easy to wire, it is widely used for safety monitoring in homes, hotels, apartments and other places where combustible gas exists. Can detect natural gas, liquefied petroleum gas, and artificial coal gas.
The working voltage of the detector is DC power supply. After alarming, a pair of relay passive contact signals can be output (normally open and normally closed can be set by jumpers), which can be used to control ventilation equipment or provide normally open or normally closed alarm contacts for other equipment.
When the concentration of combustible gas in the environment reaches the set threshold, it can send out an audible and visual alarm signal and output a relay passive contact signal. When the combustible gas concentration in the surrounding environment drops below the response threshold, the detector in the alarm state will automatically return to normal working state.
Performance characteristics
< > High-quality gas sensor, stable, reliable, and good in consistency. The microprocessor intelligent algorithm automatically compensates for gas sensor drift. It uses a precision temperature sensor to detect the ambient temperature for compensation, completely eliminating the problem of gas sensor drift. After a false alarm, the control output is a normally open or normally closed signal test button to test the circuit of the alarm. The alarm output light shows the normal operation and alarm status of the alarm. The outer casing is made of fireproof B engineering plastics, which is beautiful and elegant. Performance parameters:
