PKI-C
Introduction
The Installation, Operation and Maintenance manual applies
to the cartridge fire damper types PKI-C E60S, EI60S, EI90S,
EI120S, produced by IMOS-Systemair, contains basic informati-
on and recommendations regarding the design, installation and
usage, which need to be followed in order to guarantee a proper
and trouble-free operation of the unit. The key to this is to read this
manual thoroughly, use the damper according to the instructions
provided in it and to adhere to the safety requirements.
Warning
Some of the fire damper parts might have sharp edges – therefo
-
re it is necessary to use gloves during the installation and usage
of the damper.
In order to avoid electrical shock, fire or other damage that might
occur as a result of incorrect usage and operation of the unit, it is
important to comply with the following principles:
•
It is necessary to install the system according to the Installation
manual.
• It is necessary to perform the fire damper check according to
the manual.
Operation
General Information
The IMOS – Systemair cartridge fire dampers are defined as fire
closures for ventilation ducts, to be installed in the spot where
the ventilation duct passes through the fire partition wall, or at the
end of the duct in front of the outlet. In case of a fire the dampers
work as a fire safety element and prevent the fire from spreading
throughout the ventilation duct during a specified amount of time.
•
All the units are actuated by springs.
• Additional accessories, such as flexible couplings, disk valves
etc., can be ordered separately.
•
The accessories are supplied separately and unmounted, rea-
dy to be mounted on site by the responsible staff.
The dampers are to be operated in a workplace which is protected
from weather conditions and to be used in ventilation ducts distri-
buting the air without any other mechanical or chemical contami-
nation in the following operating conditions:
• The maximum air flow speed of 12m/s
• The maximum relative air humidity of 90%
•
The temperature falling within the range of -10 to +65°C
In terms of noise, the IMOS – Systemair fire dampers are passive.
Increased noisiness only occurs while the damper is being opened
or closed as a result of inspection or fire, which should not last
longer than 5 seconds.
Note:
The accessories for mounting – cover plates for dry instal-
lation and a flexible coupling for inspection simplification – can be
ordered along with the fire dampers.
As a standard, all the cartridge fire dampers are equipped with
a thermal fuse link, which, after having reached or exceeded
the temperature of 72 °C with a ± 1,5 °C tolerance, unblocks the
actuating springs, which causes the damper blades to close. Upon
request it is possible to supply thermal fuse links with a higher
fusion temperature.
1 Installation Manual
• The cartridge fire dampers are installed into the duct, either in
the place where the fire-proof wall is, or at the end of the duct
in front of an air valve or a similar outlet. (The cartridge fire
dampers are installed into the duct, either in the place where
the fire-proof wall is into a transversal duct, or at the end of the
duct in front of an air valve or a similar outlet.)
• The pitch between the ducts and the fire dampers must be at
least 200 mm, according to the STN EN 1366-2 regulation.
•
According to the STN EN 1366-2 regulation, there must be at
least a 75 mm gap between the wall and the ductwork with the
fire damper.
• The fire damper is embedded into the fire partition construction
into duct in such a way that when the damper blades are in the
CLOSED position, thay will be entirely situated inside the wall.
•
The damper can be embedded into a wall or a ceiling with a
minimum thickness according to the STN EN 1366-2 regulation
for the respective fire resistance class.
•
All the dampers can be installed with a horizontal or a vertical
blade axis.
1.1 Embedding the PKI-C into a Wall / Ceiling Using Gypsum,
Mortar or Concrete – Wet Installation (see Fig. 1)
1. For installation purposes, make a round opening with a mini-
mum diameter of Ød + 60 mm into the wall.
2. Insert the duct inside the middle of the opening.
3. Fill in the space between the wall and the duct with gypsum,
mortar or concrete, while paying special attention to not conta-
minate the inside of the duct. Plaster leakage can be preven-
ted by using the cover plates.
4.
Insert the fire damper into the duct and ensure that the whole
blade of the closed damper is situated within the wall.
5. Check the damper’s functionality (see the Operation manual).
1.2 Installation Into the End of a Duct with a Valve (see Fig. 2)
PKI-C can be installed into a wall/ceiling at the end of a duct with a
disc valve (the valve needs to be separately ordered from the ADP
catalogue – an advisable type would be the plastic valve „Balance-
E“ from Systemair AB, Sweden). The installation is the same as
described in section 1.1, remembering that the end of the duct
must stay in allignment with the side of the wall/ceiling where the
valve is going to come. By installation PKI-C must be placed with
surface which contacts the closed blades in distance 50±10 mm
from end of the duct. The blades must be open in the direction into
the duct.

1.3 Embedding the PK-I into a Wall Using Mineral Wool – Dry
Installation (see Fig. 3)
1. For installation purposes, make a round opening with a mini-
mum diameter of Ød + 60 mm into the wall.
2. Insert the duct inside the middle of the opening.
3. Attach the cover plates to the wall around one side of the duct.
4. Fill in the space between the wall and the duct with mineral
wool, while paying special attention to not contaminate the in-
side of the duct.
5. Attach the cover plates to the wall around the other side
of the duct.
6.
Insert the fire damper into the duct and ensure that the whole
blade of the closed damper is situated within the wall.
7. Check the damper‘s functionality (see the Operation manual).
COVER PLATES ARE MANDATORY WHEN PERFORMING A
DRY INSTALLATION – the ordering code for them is PR!
