CE marking
To obtain CE marking, companies and fire dampers themselves
must fully comply with the requirements of BS EN 15650.
Companies must be:
 ISO 9001 accredited
 Monitoring production through a program of Factory Production
Control (FPC)
 Issued with a certificate of constancy of performance by a
notified body
Fire dampers must be:
 Fire tested to BS EN 1366-2
 Classified to BS EN 13501-3
 Thermal release mechanism tested to ISO 10294-4
 Stainless steel and multiple damper assemblies assessed
against EN 15882-2
In accordance with the Construction
Products Regulation or CPR
(305/2011/EU) introduced into the UK
on the 1st of July 2013, any fire
dampers sold into the UK and EU
markets must be CE marked.
HVC currently have three CE marked installation methods for
Series 700 fire dampers.
 Plate frame in drywall partitions
 Plate frame in masonry walls
 Plate frame in concrete floor slabs
It is a legal requirement that fire dampers are installed in the way
instructed by the manufacturer. Any other installation is untested
and therefore illegal.
Responsibility for ensuring correct installation lies with all parties in
the supply chain.
This brochure gives a short overview of the installation methods.

NCA Series 700
Motorised leakage rated fire dampers
NCA Series 700 fire dampers
Designed to maintain compartmentation in buildings at locations
where ductwork penetrates a fire barrier, a fire damper’s basic
function is to prevent fires spreading through ductwork.
NCA Series 700 motorised leakage rated fire dampers go beyond
this basic requirement with their reduced leakage design, making
them suitable for areas requiring dampers with ‘ES’ classification.
Uniquely easy to install, S700 fire dampers are surface mounted,
making use of fixing lugs and a simple plate frame with factory
punched fixing holes, installations require no backfilling, sealing or
pattress frames. This makes them especially useful for
refurbishment projects where disruption needs to be minimised.
S700 fire dampers are currently available with 120 minute rated
installations to suit drywall partitions, masonry walls and concrete
floor slabs (single sections only). All installations are classified ‘i↔o’
meaning air is permitted to flow in either direction through the
damper.
Actuators are Belimo BF series, are available in 24 or 230 volt
variants and are supplied with a 72°C rated thermal probe.
Design features
Materials Plate frame - 1.5mm galvanised steel
Case, internal frame and actuator mounting bracket - 1.2mm galvanised steel
Blades - 0.7mm galvanised steel (double layered)
Frame side, top and bottom seals - 0.4mm stainless steel (grade 301)
Drive system - Steel throughout (BZP coated)
Sizes Minimum: 200mm x 200mm / 200mm diameter nominal
Maximum: Single section - 1000mm x 1000mm / 1000mm diameter nominal
Multiple section - 2074mm x 2074mm / 2074mm diameter nominal
Units requiring a nominal width/height/diameter of less than 200mm can be supplied using reducing spigots
Operation Opposed blade, linkage driven (out of airstream)
Controls Single section assemblies: Belimo BF24-TN or BF230-TN actuator (power open, spring return, non-modulating)
complete with 72°C thermal probe
Multiple section assemblies: Belimo BF24 actuators (power open, spring return, non-modulating) complete with
relay box assembly (24V or 230V supply) with 72°C thermal probe

Damper design
1. Plate frame
Serves as the mounting point for
fixing the damper to the partition.
Pre-punched 5mm diameter fixing
holes assist installation on site.
2. Fixing lugs
Mounted at the top of the case on
either side, these serve as
mounting points for hanging the
damper from either 8mm or 10mm
diameter threaded drop rods.
Fixing lugs are not required to be
used in horizontal applications.
3. Case
Comprises the spigots and
encapsulates the inner frame.
4. Inner frame
The main component around which
other components are fitted.
Formed bushes in the side
members hold steel tube axles to
which the blades are mounted.
5. Blades
Aerodynamic formed steel blades
designed to present low resistance
to airflow when open, but also to
provide the required strength and
level of shut-off when closed.
6. Stainless steel seals
Formed stainless steel seals sit
between the inside frame and
blade edges and ends.
7. Belimo BF series actuator
A specialist fire damper actuator
with integrated thermal probe,
powered open during normal use,
springs closed when required.
Positioned on damper’s left side
(as shown) unless specified.

Installation S700-2VP
NCA Series 700 fire damper c/w plate frame in drywall partition
Installation procedure:
Hang the damper using the two factory fitted fixing lugs from drop rods
(M8/M10) securely attached to a structural element of the building
distinct from the partition itself.
Position the damper spigot (plate frame side) centrally within a correctly
sized aperture, constructed in accordance with our S700 installation
instructions.
Screw the damper to the wall through the factory punched fixing holes
in the plate frame, ensuring all screws gain a positive fix on the steel
framework inside the partition.
Fit the actuator’s thermal probe to the top half of ductwork.
No backfilling or sealing of the aperture, nor a pattress frame are
required.
The damper must be installed so blades run horizontally.

Control panels
HVC are able to supply, install and commission a full range of fire
damper control panels to suit S700 fire dampers throughout the UK
and Republic of Ireland, including:
● Single/multiple zone electro-mechanical systems
● Basic addressable systems
● Fully addressable systems
For further information on control panels please contact HVC.
Separation between fire dampers and between fire dampers
and construction elements
● There should be a minimum of 200mm of supporting
construction between fire dampers installed in separate ducts.
● There should be a minimum of 75mm of supporting
construction between the fire damper and any adjacent
construction element, e.g. a wall or ceiling.
Further information: Direct field of application
11
Supporting construction
A test result obtained for a fire damper mounted in or on the face of
a standard supporting construction is applicable to a supporting
construction of the same type with a fire resistance equal to or
greater than that of the standard supporting construction used in the
test (thicker, denser, more layers of board etc.)

Single/multiple section assemblies
Single sections
Single section damper assemblies comprise a single damper
section complete with single actuator with integrated 72°C rated
thermal probe (Belimo BF24-TN or BF230-TN).
Multiple sections
Supplied factory assembled and comprising either two or four
dampers depending on the size required.
Each component section uses a single Belimo BF24 actuator which
is connected on site to a fire damper relay box.
Unique to HVC, fire damper relay boxes ensure that the component
single section dampers in a multiple section assembly operate in
unison while opening and closing.
Fire damper relay boxes power up to four actuators and are
equipped with a single thermal probe which should be fitted to
ductwork as normal. Relay boxes should be fitted to the partition or
floor, not ductwork.

Installation should take into account the requirements of future
maintenance, with a view to providing adequate access to fire
dampers for testing and cleaning purposes.
We are able to supply a full range of access doors to facilitate
access into ductwork.
Installation into chlorinated environments
We are unable to supply S700 fire dampers suitable for installation
into chlorinated environments, swimming baths for example.
Any dampers installed into environments where chlorine is present
shall be considered to be installed in an unsuitable location and will
therefore not be covered by our standard 12 month warranty.
Installation
Maintenance of fire dampers is essential to ensure they remain in
good working condition for the life of the building.
