During the installation process, the blade position must be “CLOSED”.
During the installation process, the control mechanism must be protected against pollution and damage.
Fire dampers are suitable for installation in any position in vertical and horizontal passages of fire
separating structures.
The gap between the installed damper and structure must be completely filled with approved material.
The distance between the fire damper and structure (wall, ceiling) must be at least 75 mm. If two or more
dampers are to be installed in one fire separating structure, the distance between the adjacent dampers
must be at least 200 mm.
The damper blade (in its closed position) must be inside of the fire separating structure. The fire damper
may also be installed outside the wall structure. The piping and damper part between the wall structure
and damper blade (marked with the BUILT-IN EDGE label on the damper body) must be protected by
fire insulation.

To provide needed access space to the control device, all the other objects must be situated at least 350
mm away from the damper control parts. At least one inspection hole must be accessible.
The damper body must not get deformed during its installation process. Once the damper is built
installed, its blade must not grind on the damper body during its opening or closing.
The damper installation procedures must completely exclude any transfer of loads from the fire separating structure
to the damper body. The connecting ducting must be suspended or supported in such a way that any transfer of load
from the connecting duct to the damper flange is completely excluded.

Before commissioning the dampers and during their subsequent operational checks, it is necessary to
check and functionally test all the designs, including the operation of any electronic elements. Upon
commissioning, these operational checks must be completed at least twice a year. If no defect is found
during two consecutive operational checks, then operational checks may be completed once a year.
Prior to the commissioning of the dampers and subsequent operational checks, the following checks
must be completed with all the designs:
Visual inspection for proper damper installation, damper interior, damper blade, blade seating surfaces,
and silicone seal.
Removing the inspection opening cover: Unscrew the pan head screws (2 pcs) and tilt remove the cover.

2(NC) - gray wire
4(NO) - blue wire
This limit switch is possible to connect in following two versions:
a) if the arm is moving … connect wire 1+2
b) if the arm is moving … connect wire 1+4

The actuator design must be checked as follows:
The blade turn to its breakdown “CLOSED” position may be checked upon cutting off the actuator power
supply (e.g. by pressing the RESET button at the thermoelectric starting mechanism BAT or by cutting
off the fire alarm power supply). The blade turn back to its “OPEN” operating position may be checked
upon restoration of power supply (e.g. by releasing the RESET button or restoration of the fire alarm
power supply).
For dampers with mechanical control (designs .01, .11, .80) the following checks must be completed:
The damper blade is turned to its “CLOSED” position as follows:
• The damper is in its “OPEN” position.
• By pressing the control mechanism button, you turn the damper into its “CLOSED” position.
• Check the damper blade adjustment in its “CLOSED” position.
• The closing must be strong, and the control lever and damper blade must be in their “CLOSED”
positions.
The damper blade is turned to its “OPEN” position as follows:
• Rotate the control lever by 90°.
• The lever gets automatically locked in its “OPEN” position.
• Check the damper blade adjustment in its “OPEN” position.
The thermal fuse function and status get checked as follows:
• To check the thermal fuse function and status, it is possible to remove the whole mechanism from the
fire damper body - the mechanism is attached to the damper body with four M6 screws.
• After the thermal fuse removal from its holder in the initiation device, check its proper operation.
• The mechanism size is marked M1 to M4 per the shutting spring force.
Actuator control without electric voltage:
A special lever (part of the actuator) may be used to manually set the dampers to any position. When the
lever is turned in the direction of the arrow, the damper blade turns to its open position. To stop the
damper blade in any position, the actuator gets locked per the actuator instructions. Unlocking is done
manually per the actuator instructions or by supply voltage restoration.
Installation, maintenance, and operational checks of the dampers may only be completed by persons
qualified for these activities, i.e. “AUTHORIZED PERSONS: trained by the manufacturer.
The dampers must be installed in compliance with all the applicable safety standards and regulations.
Actuator reset after the fuses activation:
If the thermal protection fuse Tf1 (for the temperature around the fire damper) is burned, it is necessary
to replace the actuator, including the thermoelectric trigger.
If the thermal protection fuse Tf2 (for the temperature inside the piping) is burned, separate spare part
ZBAT72 or ZBAT95 may be replaced (according to the starting temperature).

• The damper bodies are normally supplied in their galvanized sheet steel design (alternatively
stainless steel) without any additional surface finish.
• The damper blades are made of asbestos-free fire-resistant mineral fibre boards.
• The damper control devices are made of galvanized materials (alternatively of stainless steel) without
any additional surface finish.
• The springs are galvanized (alternatively made of stainless steel).
• The thermal protection fuses are made of brass sheet 0.5 mm thick.
• The connecting material is galvanized (alternatively made of stainless steel).
