Operations & Maintenance of fire dampers
Damper el. function check
If the damper is in manufacture DV3÷DV6 with electromagnet it is necessary to test the mechanism function
also with electromagnet. Electromagnet receives the signal for actuating (for example from the central building
system) releases the actuating lever (4) and mechanism closes. Adjusting lever (1) immediately moves from
position OPEN to position CLOSED. If the damper is in manufacture with terminal switch (9) it must signal
closing the leaf after actuating the mechanism
Dampers with actuator in manufactures DV7, DV9-T and DV9-T-ST
Putting damper into operation
After connecting the actuator to el. power (see wiring schemes according to damper manufacture) the
electromotor is activated and puts the damper into operation position. That means that the damper leaf opens.
Control system, which the damper is connected to signals (according to damper connection) open or closed
position of damper leaf.
Damper function check
Damper function is checked when we press and hold the switch on thermo electrical release device (heat fuse)
as shown in fig. 37. With the switch we simulate failure of heat fuse. It is necessary to hold the switch in ON
mode during the whole damper function check. Actuator puts the damper into accident position- it closes the
damper leaf with the energy of return spring of the actuator. Damper should close within app. 20-30 seconds
(depends on operation temperature). Position of the leaf is possible to check visually through inspection lid or
the leaf position is signaled by control system which the damper is connected to.
Damper must close also at any electricity supply drop out when the damper leaf is closed with energy of
actuator’s return spring.

Visual check
After putting the damper into operation mode it is necessary for all the damper types to demount the inspection
lid and check the damper leaf position and also check possible visible damper leaf and other damper parts
damages visually. Visual check is needed for both leaf positions - OPEN / CLOSED.
Operation, check and maintenance
Operation conditions
Operator keeps fire dampers in operation and in safe status during their whole period of service according to
operation manual published by the producer. It is not allowed to do any changes or modifications on the
dampers and any damper parts cannot be removed without producer’s permission. Operator provides
regular checking of the dampers according to valid instructions and norms given by the country. If not stated
in other way, operator does the damper check once per 12 months. Damper checking is provided by skilled
person. Fire damper status determined during the check is noted into operation diary with the date of the
check, name and last name in bold and signature of the person that has done the check. If any inadequacies
were determined it is needed to note also proposal for their elimination into the operation diary.
