Pressure is monitored via a transducer in the pipeline downstream from the last AVSU, this pressure is monitored for both high and low pressure (low only for vacuum). A fault on the cabling between the pressure transducer and alarm panel would result in a system fault alarm and as a result, the integrity of the CPX cabling is incomparable.

CPX Digital Area Alarm is available in two different and versatile installation models. The alarm unit provides an indication of 3 conditions of gas, normal, Low pressure, and High pressure for up to 6 Gas services.

Each service has a green normal, red high-pressure, and red low-pressure indication, the vacuum service has a green normal and red low-pressure indication and is programmed via an antimicrobial touchscreen display.
