Natural gas detector ORNO ORDC614 It is designed for continuous monitoring of interior spaces for the presence of natural gas escaping from leaks. It has a built-in high-quality semiconductor sensor with a high level of detection. Thanks to the additional relay output the device can transmit an impulse to another device when the permissible concentration is detected. Then an optical alarm is activated. LED diode and acoustic siren with a volume of approx. 70 dB Product features TEST button correct operation of the sensor optical indication red and yellow LEDs and sound electrochemical sensor alarm level 10 LEL additional relay output enables the transmission of an impulse to another device when the alarm concentration is exceeded, e.g. fan alarm siren telephone dialer additional 12V DC power supply contact, e.g. to close the valve cutting off the gas supply to the installation average service life of the internal sensor approx. 5 years Technical specifications sensor type semiconductor sensor sensitivity and time 10 LEL error 3 LEL volume level 70dB operating temperature 0°C 55°C humidity lt95 power supply 230V AC50Hz power consumption 3W dimensions 85 x 125 x 45 mm weight 290 g LEL lower explosive limit It is the lowest concentration of gas in the air at which an explosion occurs in contact with an open flame Included Orno ORDC614 sensor 1 pc power supply 1 pc quick manual
