Abb dts4302 g p l gas detector

The gas detector, depending on the model, signals leaks of methane gas or LPG gas when the concentration of gas in the room where it is installed exceeds the alarm threshold. The detector is powered by mains voltage and is equipped with an output , controlled by a relay, to which it is possible to connect a manual reset solenoid valve3), for interrupting the gas flow in the event of an alarm or alarm 1) Methane gas detector – code DTS4301 2) LPG gas detector – code DTS4302 3) Devices produced by third parties The device is equipped with a radio interface and can send, via the control unit, alarm messages to programmed mobile and landline telephones. If correctly installed, in the event of an alarm the detector: 1 signals the presence of gas through light and acoustic signals and the sending of alarm messages to predefined telephones; 2 if the alarm continues for more than 30 seconds, it activates the relay that controls the solenoid valve and interrupts the gas flow. For this function to be effective: • a manual reset solenoid valve must be installed in the gas system; • the solenoid valve must interrupt the main gas flow and therefore be positioned after the methane gas meter or the LPG gas tank and before any gas supply pipe entering the home; • the solenoid valve must be positioned outside the home and not in an internal room. The solenoid valve must therefore not be installed when the gas is taken from a cylinder kept inside the home, because the action of the solenoid valve would not be completely effective and a false sense of security would be generated The expected life of the device in use is 4 years. At the expiry date, indicated on the label on the device, consult the supplier for replacement
