Basic Operation

The VentGuard has a simple key switch operated ON/OFF function and a panel mounted flush emergency stop button to avoid accidental operation.

Turning the key to the ON position will enable the gas supply providing the remote emergency stop and CO2M interfaces are not in alarm.

If the intake or extract fan are not in operation the panel will still allow gas through until they have been open circuit for a full 30 seconds. As some systems use the valve status to enable the fans this will allow the fans to get up to speed and provide a healthy signal to the VentGuard without any issues.
