VA input in standby mode (the valve enabled
–disabled) is connected with the CA
output, which makes it possible, among other things, to carry out the damper ventilation
function without any interruption. Option with venting:
CA output in standby mode is vented by means of an integrated drain (vent) valve.
After pressurising VA input (from the alarm or ventilation box), connection between VA
input and CA output is set up.
Installation:
1. Make the following connections:
CA
– OPEN side of the actuator
VA
– OPEN ventilation or smoke extraction circuit
