7. TRANSPORT AND STORAGE CONDITIONS
Fire dampers are packed in cardboard boxes or placed on pallets. They are wrapped in plastic film or other protective
material in order to protect them against damage. Fire dampers may be transported using any means of transport,
provided that protection against the weather is ensured. Fire dampers placed on transport vehicles should be secured
in such a way that they do not move during transport. Before installing fire dampers, conduct visual inspection of
each unit. Do not move a fire damper by its connection cable or place it in such a way that its weight is supported on
the release and control mechanism. Fire dampers cannot be hit or dropped. When moving and installing a fire
damper, place it in such a way so that it is supported on its side panels or body edges.
Fire dampers should be stored in closed interior spaces which ensure protection against the weather. When fire
dampers are stored on the floor, they should be placed on protective supports in order to protect them against
damage.
8. MAINTENANCE AND SERVICE (REPAIRS)
Products manufactured by „MERCOR” SA should undergo periodic technical inspections and maintenance at least
every 12 months throughout their service life, i.e. in the warranty period and later. Inspections and maintenance
should be carried out by the manufacturer or by companies authorised to service „MERCOR” SA’s products.
The obligation to conduct regular inspections of fire equipment is stipulated in § 3 section 3 of the Regulation of
Minister of Internal Affairs and Administration dated 7 June 2010 on the fire protection of buildings, other structures
and areas (Dz. U. [Journal of Laws] 2010 No. 109, item 719).
The recommended operations to be carried out between the inspections are as follows:
check the condition of electrical connections, paying particular attention to mechanical damage;
Inspections of the condition of the supply voltage for the devices, which allowed the following tolerances:
24V±10% for electric actuators
24V±2% for electromagnetic release mechanism
230V ±10% for electric actuators
230V±2% for electromagnetic release mechanism
check the condition of the fire damper’s body, paying particular attention to mechanical damage;
check for causes that could possibly affect the correct operation of the fire damper.
To enable full service inspections as well as servicing, including servicing under the warranty, such as visual
inspections and repairs, the user has to ensure physical access to the product, e.g. by removing thermal
insulation/suspended ceilings and disassembling other systems if they prevent free access to the product, etc.
In the case of fire dampers installed in ducts, it is recommended to make a service duct such as the mcr KRW type,
for instance.
If devices are installed on the roof, ensure the possibility to enter the roof (ladder or lift).
