Modern alarm device for detecting natural gas concentration inside rooms. It serves for continuous monitoring of the presence and detection of flammable gases leaking from leaks. The device uses a high-quality semiconductor sensor, allowing for a high detection rate. The detector has optical and acoustic notifications, which are activated when the permissible concentration is exceeded. Alarm level: 10% LEL, the TEST button allows for checking the sensor's correct operation. An additional relay output allows for sending a signal to another device when the alarm concentration is exceeded (e.g. fan, alarm siren, telephone dialer), with an additional 12V DC power contact output, e.g. to shut off the gas supply valve in the installation. The average lifespan of the internal sensor is about 5 years.
