to  EC  Np.  842/2006  Article  3.  The  ability  of  the  LES-RACK-M1  equipment  to  continuously  perform 
effectively completely depends on adequate servicing and regular testing. The LES-RACK-M1 equipment 
must only be inspected by persons who meet the required qualification conditions. These persons must 
not interfere with the circuits, parts linked with the network under the cover under any circumstances 
because  there  the  risk  of  an  electric  shock.  Repairs  must  only  be  carried  out  by  properly  trained 
employees  of  the  service  organization  or  the  manufacturer.  Before  the  inspection,  the  person 
responsible for the  operation of equipment  must  be informed about the  inspection of the equipment 
LES-RACK-M1. Before the inspection and commissioning, related equipment, if any  is connected, must 
be prevented from running, e.g. disconnecting energy, fire valve, air conditioning unit.  
The equipment must be inspected after each use or if the permitted working limits are exceeded. 

Inspections by the user 

Consistent  adherence  to  the  inspection  time  schedule  and  maintenance  is  carried  out  to  ascertain 
defects  in  the  LES-RACK-M1  equipment  in  the  initial stage.  Allows  correction  before  the  equipment  is 
automatically activated and error-free function in the case of fire. The inspections  of equipment must 
always prove conformity with the general requirements and technical parameters in this manual.    

 

Inspection after 1 week 

Visual inspection of any risk changes and the tightness of the protected space that would decrease the 
efficiency of the system. Visual inspection to see that the operating equipment and components of the 
system are properly located and undamaged.  
Inspection of signal lamps on the front panel 

 

Inspection after 1 month

system. 

 

Checking the protected space 

At least each month consistently check that there are no passages in the borders of the protected space 
or that other changes have not occurred that could influence the escape of the extinguishing agent or its 
efficiency. If it is ascertained that in the protected space changes in the volume or the type of the risk 
have occurred, the extinguishing system must be modified so it provides the original level of protection. 
It is recommended the type of the risk in the protected space and the volume which is occupied. It is 
recommended to regularly check that the extinguishing agent is at the required concentration and will 
be kept. 

 

Inspections by the service organization 

Repairs must only be carried out by properly trained employees of the service organization with electric 
systems qualifications according to the respective regulations. 
All electric detection and alarm systems are tested according to the recommendations of the respective 
national standards. 
All control valves are checked that they work correctly in manual operation and, consequently, that they 
work correctly for automatic operation. Checking the surface of the equipment for signs of damage or 
unauthorized interference. 
Visual inspection 

 

checking the equipment location  

 

checking the serial number 

 

checking equipment fixing
