MAINTENANCE AND SERVICE (REPAIRS)
Products manufactured by „MERCOR” S.A. 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” S.A.’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 activities 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.
Should fire dampers be installed on a roof, access to the roof should be ensured by providing a ladder or lift.
