• There must be a release lever, which releases initiation lever of control and mechanism will
displace to "CLOSED" position.
• If not, you need to contact the manufacturer and order new mechanism.
• Mechanism dimension is marked M1 to M4, according to internal forces of spring.
15.3 Before entering the dampers with actuating mechanism into operation after their assembly and
by sequential checks and following checks must be carried out.
Check of blade displacement into the breakdown position "CLOSED" can be done after cutting
off the actuating mechanism supply (e.g. by pressing the RESET button at the thermoelectrical
starting mechanism BAT or cutting off the supply from ELECTRICAL FIRE SIGNALISATION).
Check of blade displacement back into the "OPEN" position can be done after restoration of
power supply (e.g. By releasing the RESET button or restoration of supply from ELECTRICAL
FIRE SIGNALISATION).
15.4 Manual operation
Without power supply, the damper can be operated manually and fixed in any required position.
Release of the locking mechanism can be achieved manually or automatically by applying the
supply voltage.
15.5 It is recommended to provide periodical checks, maintenance and service actions on Fire
Equipment by Authorized persons schooled by Producer.
15.6 All effective safety standards and directives must be observed during fire damper assembly.
15.7 Dampers could be displaced into position “CLOSED” only in case that ventilator, or Air Handling
Unit is switched off. The goal is the securing of proper closing and safe function of Fire Damper
in case of Fire.
16. Spare parts
16.1 Spare parts are supplied only on basis of an order.
16.2 Control for square damper and round damper is identical.
17. Restore function of actuating mechanism after fuses initiation
17.1 If fuse Tf1 is initiated (duct outside temperature) than is necessary to change thermoelectrical
starting mechanism BAT72B-S. Whereas is initiation temperature higher than actuator
mechanism operating tempe50°C, recommended actuating mechanism manufacturer
make complete revision or change actuating mechanism and thermoelectrical starting mecha-
nism.
17.2 If fuses Tf2/Tf3 are initiated (duct inside temperature) than is possible change only part ZBAT72
or ZBAT95 (according initiating temperature).
