It is possible to check manually the correct functioning of a fire damper with electric actuator for service purposes. To do this, use a special hex key which should be placed in the socket marked on the actuator. Then, by rotating the hex key, the fire damper’s partition may be set in the desired position. Bearing in mind to take enough care, rotate the hex key uniformly and slowly. Too fast and violent rotation may cause damage to the internal mechanism of the actuator or the power transmission system. NOTICE Never try to open or close a fire damper’s partition by pulling it directly. Such attempts may cause damage to the self-locking powertrain of a fire damper and this is not covered by warranty. It is recommended that the fire damper were opened and closed when the ventilation system is turned off.“MERCOR” S.A. – the Company reserves the right to make modifications and changes.
