NATURAL GAS SENSOR AC230V - ON-DC-614

Technical data: Types of detected threats: natural gas Alarm volume level (dB): ?70 TEST button: yes Alarm mute: no Power supply type: mains (230V) Fault indication: yes End of service life indication: yes Dimensions - width: 82mm Sensor life: 5 years Dimensions - height: 125mm Dimensions - depth: 41mm Display: no Sensor type: semiconductor Other features: relay output, function of closing the valve cutting off the gas supply to the installation A modern alarm device for detecting the concentration of natural gas inside rooms. It is used for continuous monitoring of the presence and detection of flammable gases escaping from leaks. The device uses a high-quality semiconductor sensor that allows for a high detection rate. The detector has an optical notification and audible, which is activated when the permissible concentration is exceeded. Alarm level: 10% LEL, the TEST button allows you to check the sensor's correct operation. An additional relay output allows you to transmit a pulse to another device when the alarm concentration is exceeded (e.g., a fan, alarm siren, telephone dialer), and an additional 12V DC power contact is provided, e.g., to close the valve cutting off the gas supply to the installation. The average lifespan of the internal sensor is approximately 5 years. ** Illustrative photos.
