Fire dampers

Fire dampers are normally configured to open (normally closed) on fire alarm.

However, they can be configured to be normally open instead via NaviPad.

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.

All dampers must be wired to the same output in order to get correct results.

The fire alarm input can be configured as normally closed or normally open.
