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).
