It is a ventilation interlock system with built in two channel current monitor designed for use within commercial kitchens. It can also monitor for air quality when fitted with the required detectors.

The easy to use LCD provides clear messages giving real time information rather than just LED indications.

It is a requirement that any mechanical ventilation within a kitchen environment (both supply and extract) is switched on and running before the use of any gas appliances can take place. With the SafeAir CM if the ventilation is not switched on, the LCD display informs the operator that the fans are off and to switch on the fans and restart the panel.

The inbuilt two channel current monitor can monitor up to 20 Amps with the operating current of the fan displayed on the LCD. This information can be used to help setup during installation and can also be used to help identify potential fan faults during operation.
DP switches can also be used with the systems.

From within the panel the engineer has several “engineer functions” which can be used to aid in the setup of the system – such as displaying in real time both the inlet and outlet pressure at the gas valve (mbar) and the ability to power the valve at a button press, its with functions like these that for example a “valve let by indication” check be performed with ease.

• A let by and a dynamic pressure loss reading can be viewed by the engineer. The Gas pressure readouts on the LCD indicating the pressure on both sides of the valve.

In addition when fitted with a Medem carbon dioxide detector (CO2) it monitors the CO2 level to ensure that HSE set levels are not exceeded. Should the carbon dioxide level rise above the set low alarm level the panel LCD will advise staff to “increase the ventilation .” If the maximum allowed level of CO2 is reached the system will isolate the gas and advise the staff to ventilate the kitchen. 

The carbon dioxide levels are set out by the HSE and supported in IGEM UP19

The carbon dioxide PPM levels will be displayed on the LCD.
