KS22 V6 – Controller for G161 in Kitchens

Gas Proving

The KS22 V6 is the controller for the Duomo G161 Gas proving system. The Duomo Trio SafeStart system is installed in hotels, fast-food restaurants, schools, colleges and canteens. It securely isolates and safely restarts the gas supply. The KS22 also connects to ventilation monitoring and interlocking devices such as air pressure switches, power monitors and Carbon Dioxide alarms.

Why use a KS22 V6 Trio Safestart?

Obviously if the gas supply to a kitchen or laboratory is started with gas taps open, a gas leak will occur. Crucially, the KS22 V6 Trio SafeStart protects personnel and property from damage caused by gas leaks. In addition, this unique keypad operated control panel ensures that only authorized personnel are able to start the gas supply. For commercial kitchens the ventilation system can be initiated and checked automatically by the KS22 V6 before it allows gas to flow to any connected appliances.

What does the KS22V6 do?

Firstly the KS22 V6 automatically checks the mechanical ventilation system is turned on before allowing gas test to commence. The Trio SafeStart then checks the downstream pipework for leaks – gas taps left open. Only when it is satisfied that there are no gas taps open the electrically operated gas valve is automatically opened. All of this makes the KS22 V6 and G161 a great system for ensuring BS6173:2009 compliance.

Finally, when the gas is turned on an automatic safe shutdown will occur if:

  1. Emergency stop push button is pressed (Duomo KOB21)

  2. The Air proving device detects incorrect fan operation (Duomo FP45 Current monitor, ADP10 or ADP65 differential air pressure switch)
  3. Low gas pressure is detected
  4. High levels of Carbon Dioxide are detected by Duomo CO2MC or CO2 Alarm.
