Upon receipt of unit - Before signing for the delivery
Flourescent yellow stickers are attached to every package we
despatch detailing receipt instructions and what to do if your goods
are damaged.
The instructions on this must be followed or HVC will not be able to
assist with any claims for damage.
Prior to installation
If the damper is to be stored on site, ensure it is stored in a clean
and dry environment.
Immediately prior to fitment, remove all packaging from the unit.
Take particular care inspecting the inside of the unit for any
packing materials which may disrupt damper operation.
Installation
All fire damper installations must be carried out as stated by HVC.
Installation instructions are available to download at:
www.h-v-c.com/installations
Installation should only be carried out by competent persons. Fire
dampers are life safety devices, their effectiveness is reliant on
correct installation.
Damper edges can be sharp. The relevant PPE should be used
when handling dampers, in accordance with the relevant local risk
assessment/s.
Larger dampers can be very heavy, ensure suitable lifting methods
are used to help prevent injury.
Ensure that ductwork is appropriately supported, and that the
damper itself will not be relied upon to support ductwork.
Remove the safety cable tie from the fusible link. Failure to remove
this will render the damper inoperable.
Installation should always take into account the requirement to
provide future access for testing and maintenance, by fitting
appropriately positioned and sized access doors.

Operation
Fusible link fire dampers are passive devices, and are designed to
operate without any command from an operator or system.
Fusible links will split, closing the damper when the temperature
inside the duct reaches that embossed on the link body.
The use of electromagnets or solenoids enables the damper to be
closed remotely, however they will still close when the link’s rated
temperature is reached.
Once the damper has been shut, it can only be reset manually.
Once a fusible link has split, it must be replaced with a new unit.
Spares
An amount of spare fusible links should be kept on site.
Thank you for purchasing an NCA Series 100 fire damper.
Please ensure the following information is read, understood and

Operation Result
Cleanliness
Clean where necessary, ensuring damper is free from dust and debris.
Damage and corrosion
Check for any damage or signs of corrosion to damper components.
Drop test
Confirm operation of damper with a drop test by following the below
steps:
●Relieve the weight of the blade pack from the fusible link with one
hand placed in the centre of the pack width. Ensure bottom blade
remains parallel to top of damper at all times.
●Failure to support the blade pack from the centre will result in
damper blades falling unevenly, potentially causing damage to
the damper. In event of damage being caused, damper must be
repaired or replaced. Contact HVC for more information.
●Remove hand quickly, replicating a splitting fusible link, allowing
damper to shut due to springs / gravity.
●Perform a visual check of the blades, ensure bottom blade has
latched correctly into both lock guides.
Reset
Reset blade pack by pushing (or pulling if a pull ring is fitted) the
bottom blade off the lock guides and pushing blade pack up into the
header. Reset fusible link correctly.
Confirmation
Confirm that damper has been left in normal working condition.
Maintenance overview and checklist
Fire damper maintenance is essential and should be carried out in
accordance with the requirements set out in:
BS 9999 - Code of practice for fire safety in the design, management
and use of buildings.
This regulation states that maintenance of air conditioning and
ventilation equipment, including fire dampers is of paramount
importance both in preventing fire and in ensuring that measures taken
to mitigate its consequences are effective when needed.
●The maintenance steps below should be carried out by a
competent person at least once per year.
●Local conditions should be taken into consideration when
deciding a test plan, more frequent tests may be necessary. For
example if dusty conditions are prevalent.
●Series 100 CE marked fire dampers have been designed to
operate without lubrication. Do not introduce any as it will attract
dust and dirt.
