Parts and function

Parts and function
4.2 FKS-EU with spring return actuator
Fire dampers are used as safety related components in
ventilation systems. The fire damper is used as a shutoff device to prevent fire and smoke from spreading
through ducting. During normal operation the damper
blade is open to enable air passage through the ventilation system.
If the temperature increases in the event of a fire, the
damper blade closes. Closure is triggered at 72 °C (
95 °C in warm air ventilation systems). If the damper
blade closes due to a temperature increase (i.e. in the
event of a fire), it must not be reopened.
To ensure proper functioning of the fire damper, a test
can be carried out. Ä 47

⑦ Release mechanism
The spring return actuator enables the motorised
opening and closing of the damper blade; it can be activated by the central BMS. As long as power is supplied
to the actuator, the damper blade remains open. In the
event of a fire, the internal thermoelectric release mechanism closes the damper blade when at least one of the
following is true:



Temperature in the fire damper > 72 °C or > 95 °C
Ambient temperature outside the release mechanism > 72 °C
The power supply is interrupted (power off to close)
As standard, the spring return actuator is equipped with
limit switches that can be used to indicate the damper
blade position.
Functional description
In fire dampers with a fusible link, damper closure is
triggered by the fusible link. If the temperature inside the
fire damper rises to 72 °C or 95 °C, the fusible link triggers a coil spring mechanism. The coil spring mechanism then causes the fire damper to close.
As an option, the fire damper can be either supplied or
subsequently fitted with one or two limit switches. The
limit switches can signal the damper blade position to
the central BMS or fire alarm system. One limit switch
each is required for damper blade positions OPEN and
CLOSED.

Air transfer units prevent fire and smoke from spreading
in buildings. The thermal release mechanism closes the
air transfer unit when the release temperature (72 °C) is
reached. Smoke can, however, spread below this temperature. Air transfer units are installed in places where
the general building inspectorate sees no risk, for
example:

4.4 FKS-EU with spring return actuator
and duct smoke detector
As an inlet for additional supply air in the walls of
required corridors (escape routes) if the units are
installed near the ground (up to 500 mm above
OKFF)
In installation shafts as long as they have sufficient
fire resistance where they penetrate compartment
floors
In installation ducts as long as they have sufficient
fire resistance where they penetrate compartment
floors or walls (except for necessary corridors or
escape routes)
If the duct smoke detector detects smoke, the spring
return actuator closes the damper blade. This prevents
smoke from being transferred via ductwork into adjacent
fire compartments even before it reaches a temperature
that would trigger the thermoelectric release mechanism.
As long as power is supplied to the actuator, the
damper blade remains open. In the event of a fire, the
fire damper shuts when at least one of the following is
true:




Smoke detected at the smoke detector
Temperature in the fire damper > 72 °C
Ambient temperature outside the release mechanism > 72 °C
The power supply is interrupted (power off to close)
The air transfer unit consists of the FKS-EU fire damper
with general building inspectorate licence Z-19.18-2127,
with a thermal release mechanism for 72 °C and with
cover grilles on both sides, but without a duct smoke
detector.


Operating components, electric actuator, and
inspection access must remain accessible for
inspection and maintenance work.
Loads imposed on the casing may impair the function of the fire damper. The fire damper must hence
be installed without torsion.
Mortar-based installation: The perimeter gap »s
« must be large enough such that mortar can be
filled in even in case of thicker walls.
Close larger installation openings or cut holes
according to the wall structure, e.g. masonry work.
Before installation: Perform a functional test, then
close the fire damper.Ä 47
Fig. 9: Installation opening in a solid wall
Depending on the local conditions and the size of the
fire damper, installation openings in a solid wall require
a lintel ①. The size of each installation opening is given
in the installation details.

6.1 Ducts
Ducts of combustible or non-combustible materials may
be connected to fire dampers.
6.2 Transport and installation protection
Fire dampers without an installation block from a width
of 400 mm and above have a transport and installation
safety device.
This safety device must not be removed until after
installation (after the hardening of the mortar).
To remove the transport/installation protection, pull it out
of the fire damper on the operating side Fig. 34.
Fig. 35: Limiting loads
Ducting must be installed in such a manner that it does
not impose any significant loads on the fire damper in
the event of a fire.
The expansion of ducts in the event of a fire can be
compensated by brackets and turns, Fig. 35.
Note
For further information please refer to the guideline
regarding fire protection requirements on ventilation
systems (Lüftungsanlagen-Richtlinie, LüAR).

Fig. 46: Functional test
DANGER!
TROXNETCOM systems allow for automatic functional
tests; they do not replace maintenance and cleaning,
which have to be carried out in regular intervals or
depending on the condition of the product. The documentation of test results makes trends visible, e.g. the
running time of actuators. They may also indicate the
need for additional measures which help to maintain the
system's function, e.g. cleaning of heavy contamination
(dust in extract air systems).
Danger due to malfunction of the fire damper.
If the damper blade has been opened by means of
the crank handle (without power supply), it will no
longer be triggered by a temperature increase, i.e. in
the event of a fire. In other words, the damper blade
will not close.
To re-establish its function, connect the power
supply.

Commissioning
Before commissioning
Before commissioning, each fire damper must be
inspected to determine and assess its actual condition.
The inspection measures to be taken are listed in the
table on Ä on page 54.
Operation
During normal operation the damper blade is open to
enable air passage through the ventilation system.
If the temperature in the duct or the ambient temperature rises in the event of a fire (≥ 72°/≥ 95°), the thermal
release mechanism is triggered and closes the damper
blade.
CLOSED fire dampers
Fire dampers which close while the ventilation and
air conditioning system is running must be inspected
before they are opened again in order to ensure
their correct function Ä ‘Inspection’ on page 52.

or other parts can lead to injuries.
Make sure that the damper blade cannot be
released inadvertently.
Cleaning
The fire damper may be cleaned with a dry or damp
cloth. Sticky dirt or contamination may be removed with
a commercial, non-aggressive cleaning agent. Do not
use abrasive cleaners or tools (e.g. brushes).
Inspection
The fire damper must be inspected before commissioning. After commissioning, the function has to be
tested in regular intervals. Local requirements and
building regulations must be complied with. The inspection measures to be taken are listed under
Ä on page 54. The test of each fire damper must be
documented and evaluated. If the requirements are not
fully met, suitable remedial action must be taken.
Repair
Regular care and maintenance ensure operational readiness, functional reliability, and long service life of the
fire damper.
The owner or operator of the system is responsible for
the maintenance of the fire damper. The operator is
responsible for creating a maintenance plan, for defining
the maintenance objectives, and for the functional reliability of the fire damper.
For safety reasons, repair work must only be carried out
by expert qualified personnel or the manufacturer. Only
original replacement parts are to be used. A functional
test Ä 47 is required after any repair work.
10.2
Lubricating points
Only lubricate the fire damper if the damper blade
cannot be opened or closed easily. Use only oil or
grease that is free of resins or acids.
Functional test
The functional reliability of the fire damper must be
tested at least every six months; this has to be arranged
by the owner or operator. If two consecutive tests, one
6 months after the other, are successful, the next test
can be conducted one year later.
The functional test must be carried out in compliance
with the basic maintenance principles of the following
standards:
