Operation and maintenance manual
NCA Series 700 motorised leakage rated fire damper
Regular inspection and maintenance of fire dampers is essential to
ensure they remain in good working condition. It is the system owner's
responsibility to ensure this is carried out.
In accordance with EN 15650:2010 fire damper maintenance routines,
such as that given below, must be carried out at intervals not exceeding 6
months.
Some automatic systems may allow more frequent testing (48 hours or
less) and this may be required by national regulation.

Notes
Fitted to ductwork near the damper, this indicates the damper is powered
open (its normal working state)
Check these are secure and that all fixings are present and tight
(4 qty M6 bolts on actuator, 2 qty screws on probe)
Actuators are not user servicable
If damaged the actuator must be replaced
Both sides of the damper blades should be easily accessible.
All damper blades should be in the fully open position.
Gently try to move each blade by hand, none should rotate.
Ensure there is nothing present which is obstructing or could obstruct the
damper blades operating
Use a damp cloth, brush or vacuum cleaner to remove any dirt and debris.
Pay close attention to blade ends and stainless steel seals
If damaged or corroded dampers must be replaced
Depress the 'TEST' button on the thermal probe and visually confirm the
damper closes correctly in around 16 seconds.
Release the 'TEST' button on the thermal probe and visually confirm the
damper opens correctly in under 120 seconds.
Is there anything that does not look correct, do you have any doubts etc.?
