We Manufacture Minimum Contact Guages which has electrical contacts. It should be connected to the pipeline gas failure alarm which has two signal lights, a buzzer & an “ON/OFF” switch.
When the contact gauge is connected to the power supply and the ON/OFF switch of the alarm is switched “ON”, green light will show indicating that the electrical supply serving the contact gauge & alarm are working correctly. The green light should show at all times when the pipeline is in use. The other signal light viz red is a warning light which automatically shows & the buzzer rings when the pressure in the running cylinder has fallen to a determined value. Put the switch to “OFF” position after which the reserve cylinder should be brought into operation
promptly to ensure continuity of supply.
