KS22 – Controller for use with G621 in Kitchens

The KS22 is the controller for the Duomo G621 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 KeyStart 22 Controller – KS22 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 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 before it allows gas to flow to any connected appliances.

What does the KS22 do?

Firstly the KeyStart 22 automatically checks the mechanical ventilation system is turned on before allowing gas test to commence. The downstream pipework is then tested for leaks (gas taps left open). Only when it is satisfied that there are no leaks the electrically operated gas valve is automatically opened. All of this makes the KS22 and G621 a great system for ensuring BS6173:2009 compliance.

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

Emergency stop push button is pressed (Duomo KOB21)

The Air proving device detects incorrect fan operation (Duomo FP45 Current monitor, ADP10 or ADP65 differential air pressure switch)

Low gas pressure is detected

High levels of Carbon Dioxide are detected by Duomo CO2MC or CO2 Alarm.
