5.6 Damper control
5.6.1 Close-off dampers
The outdoor air and exhaust air ducts close-off dampers can be controlled by digital outputs or be
hard-wired to the supply air fan relays for normal and reduced speed in such a fashion that the
damper is open when the supply air fan is running. When using pressure controlled fans the digital
activation signal is activated as soon as the fan has start conditions. This signal can be used to open
the close-off damper.
5.6.2 Fire dampers
Fire dampers are normally configured to open on fire alarm. However, they can be configured to be
normally open instead via the display.
Se chapter 16.15 for more information on the function.
Fire damper exercising
Fire damper exercising can be configured. The exercise interval is settable. To be able to use this
function, all the dampers must have end-position switches.
The digital input: "Fire damper end-switch monitoring" should be wired to all the fire damper end
position switches.
When the test cycle is initiated, the output "Fire dampers" will be activated and the dampers will
begin to move. Within the set time (90 sec) the signal on "Fire damper end-switch monitoring" must
change to indicate that the dampers have left their normal positions. If not an alarm will be
triggered.
Then, within the set time, ”Fire damper, end-switch monitoring” must change again to indicate that
all the dampers have reached the other end position. If not an alarm will be triggered.
When all dampers have reached the end position the output "Fire dampers" will be reset to drive the
dampers back to normal position. Again, within the set time (90 sec) the signal on the input "Fire
damper end-switch monitoring"must change to indicate that the dampers have left the end positions.
If not an alarm will be triggered.
Then, within the set time, "Fire damper end-switch monitoring" must change again to indicate that
all the dampers are back to their normal positions. If not an alarm will be triggered.
The controller can be configured to stop the air handling unit during the damper testing.
