pointer, washer 8mm A/ screw into position and tighten to 5Nm max torque.
19. Routine Inspection. Testing and Maintenance
19.1 In accordance with BS 9999 Annex W.1, inspection should be undertake annually. Local
regulations/conditions may override this with periodic Inspection being carried out more frequently
where corrosive or dirty conditions prevail. The maintenance log should be reviewed at each
inspection and the frequency adjusted as required dependent upon findings. (BSB recommend a
maximum of 1 year between inspections and to start more frequently initially and reduce
frequencies only if conditions are proven to allow).
19.2 or actuators fitted with a thermal fuse), check T is correctly fitted to duct. (Refer to section 15)
19.3 Where a thermal fuse is present, the LED on the thermal fuse will be illuminated when the actuator
is powered. Refer to Section 20.1, if it is not illuminated.
19.4 Remove access door to reveal damper's internal elements.
19.5 Visually inspect the internal damper elements for signs of corrosion, obstruction or accumulated
dirt/dust.
19.6 If there are any obstructions or if the damper's blades/gasket seals are dirty, they need to be
cleaned. It is recommended to remove the actuator before cleaning the internal elements to avoid
trapping your fingers. (Refer to section 20)
19.7 Visually check that the damper is in its 'powered state' (opposite to fail-safe position). If the damper
is not in its 'powered state', refer to fault finding chart, otherwise continue.
19.8 Temporarily remove electrical power to the actuator (either by using the test switch on the thermal
fuse (T actuator), or by isolating power to actuators without a thermal fuse).
19.9 The actuator should reach its SPRING-END (fail-safe position) in <30 seconds. Confirm visually
that the blade position and indication pointer on the actuator corresponds.
19.10 Release the T test switch (T ) and ensure it reaches its DRIVE END in <60 seconds. Confirm
visually that blade position and indication pointer on the actuator corresponds.
19.11 If the damper has seized (failing to reach either drive end or spring end):-
19.11.1 Isolate and remove actuator.
19.11.2 Spray a light lubricant into blade end bearings through the holes on the side
gaskets.
19.11.3 Using the 12mm A/ spanner on the TD box Drive Shaft, begin to progressively
operate the blades manually.

19.12 Open the damper using a 12mm A/ spanner on the TD box. Check for foreign
items in and around blades, paying particular attention to blade fishtails. Remove
any obstructions.
19.12.1 Clean the inside of the damper case where the blades make contact with the
gasket seals. Use a soft cloth with a light application of light lubricant. (Connect
Duck Oil recommended).
19.12.2 Lightly apply a light lubricant into blade axle bearings depressing the side gaskets
to allow access. It may be necessary to re-apply lubricant a couple of times, whilst
operating the damper using the 12mm A/ spanner, until the torque has reduced to
less than 5Nm for mid-range travel, and 10Nm for full damper closure.
19.12.3 There should be no more than a thin film of lubricant applied. Remove all excess
lubricant. It is particularly important as excess oil will tend to collect dirt and dust
which will have a negative effect on dampers remaining clean.
19.12.4 Refit the actuator (Refer to section 16).
19.12.5 Switch on power to the actuator.
19.12.6 The actuator should reach its 'powered state' position in <60 seconds. If it does not.

(powered state). A quarter turn in the opposite direction locks it. Visually confirm that
the damper is in its 'normal state'.
22.5.4 Release the motor if it is locked by turning the crank handle a quarter turn in the
winding direction and allow the damper to travel to 'fail-safe' position.
22.5.5 Visually confirm that the damper is in the correct position.
22.5.6 Switch on power to actuator. LED on T (where present) will illuminate. The actuator
will start to travel to the DRIVE-END (normal state) position, reaching it within 60
seconds, visually check that the damper blade-position and signal corresponds.
22.5.7 IMPORTANT: Press and hold test switch lever on T to allow to allow actuator to travel
to its SPRING END position. Visually check that the damper blade position and signal
corresponds. (This is to ensure that the actuator functions electrically and overrides
the manual reset facility -should it have been used-, as it is feasible to leave the
damper inadvertently reset without the T being functional if this test is not carried out!)
22.6 Ensure the damper is left in its 'normal state' (powered) before re-fitting access doors.

SD-TD - Inspection and handover check sheet
No. Question Guidelines Confirmed
Are the dampers the correct type?
Are the dampers individually correctly
identified?
Are the dampers located correctly
Is the installation method tested and approved
for the type of barrier that is being protected?
Is the damper installed & fixed in accordance
with the manufacturers tested and approved
method?
Have access doors been fitted to the ductwork
allowing the damper blades to be inspected?
Is access through the ductwork, to the damper
unhindered?
Is the penetration only used by the damper and
not used for the passage of other services?
Using the access opening provided. has the
damoer been left in the open position?
Is the correct power supply wired to the
actuator and power is on? (if motorised)
Is the Thermal use/link correctly installed?
Have the damper blades been released to
simulate failure of thermal release mechanism
(damper 'drop test')?
Have the dampers been checked for internal
cleanliness and free from damage and debris?
Have the dampers blades been re-set following
the drop test and the access panel replaced?
At the time of the damper handover, is the fire
damper installation completed in accordance
with the above check list?
Is the damper installation completed and
available for handover prior to system
commissioning?
Is the completed handover register cross
referenced back to the identification codes
listed in the system designer's damper
schedule?
Confirm the damper is the correct type and
model.
Unique system identification and location
reference aids commissioning and must be
clearly indicated on the damper or agreed
location.
The damper position shall be checked against
the installation drawings/details.
Ensure modifications have not been made to
the tested method.
Check the damper has been fixed correctly to
the fire barrier and is independently supported
from the ductwork
Access doors are required for commissioning
and servicing.
Unobstructed space shall be provided for safe
access to damper. Also consider access
through ceiling voids and adjacent services.
The presence of other services will invalidate
the approved installation method.
Check blade position
Check power is on to actuated damper to
ensure testing can be carried out
Confirm fitted correctly to ductwork/damper
Test button on thermal fuse probe shall be
used or fusible link removed to drop test
With the damper in the closed position inspect
for damaoe and contamination.
After re-setting the damper blades, check
position of blades to ensure correct.
Damper installer to record, on the register, any
incomplete works relevant to the damper
installation.
Obtain relevant acceptance of the damper
installation from the system designer
