GENERAL INFORMATION

 

 
Generally 

LES-RACK-M1

  is  an  independent,  fully  automatic,  detection  and  fire  extinguishing  equipment.  It  is  for 

fire  fighting  protection  of  telecommunication  and  control  boxes,  server  boxes  or  other  distribution 
boxes with a 19 “frame. 
It consists of a fully equipped automated fire detection, control, evaluation, communication system and 
a  fire  fighting  unit.  The  extinguishing  agent  is  non-corrosive,  does  not  damage  data  stored  on  record 
carriers.  The  extinguishing  agent  is  non-conductive  and  can  also  be  used  to  extinguish  electric 
equipment with a nominal voltage up to 1,000 V.  
The  service  life  of  the  equipment,  with  the  exception  of the  battery,  is 10  years  from  the  year of the 
production. The service life of the batteries depends on the working environment mainly at a working 
temperature of 25°C. Generally the higher the temperature the shorter the service life. 
Because  the  principle  of  CONTEG,  is  to  continuously  improve  its  products,  the  company  reserves  the 
right to change this data without prior notification. 

 

This  device  must  only  be  used  in  accordance  with  the  operating  conditions  in  the  accompanying 
documentation and the user manual. 
If not used according to the designation the manufacturer is not liable for damages that may arise. In 
these cases the operator exclusively bears the risk.  
 
The  operator  must  carry  out  regular  visual  and  functional  inspections  according  to  the  operating 
conditions and the maintenance plan. In necessary, the maintenance and service must be documented. 
Device  operators  of  must  announce  all  changes  and  modifications  of  the  monitored  and  protected 
device,  any  object  that  could  influence  the  efficiency  of  the  LES-RACK-M1  fire  fighting  system  (e.g. 
shadowing  of  extinguishing  nozzle  when  installing  new  equipment,  adding  or  making  new  ventilation 
holes in the box. . etc.). 

 

NOTE:  

This 

LES-RACK-M1  fire  fighting  device  assembly  and  operation  manual

  ”

is  the  working 

documentation for installing and commissioning the device. However, it cannot replace training. 

 

Working conditions 

The  device  must  be  installed  in  an  environment  protected  against  class  3K3  atmospheric  influences 
according to EN 60721-3-3 with temper5°C to 40°C. The device’s working position and location 
in the protected space will affect its correct function.  The working position must be always horizontal; 
the control panel of device must be easily accessible. The device must be in the highest possible place of 
the protected box. The device is guaranteed to work at temperatures from +5°C to 40°C with maximum 
85% humidity and in an environment with no humidity condensation.  
 

NOTE:   

If  the  temperature  of  the  device  is  above  45°C  uncontrolled  leaks  of  the  extinguishing  agent 

through  the  safety  pressure  valve  may  occur.  This  is  because  of  the  high  temperature  of  the 
extinguishing agent in the tank at which it may be gradually turn to gas. Pressure increase in the tank. If 
the pressure reaches 3Bar the safety vale opens  and the extinguishing agent may 

flow-out

 ”

from the 

tank.
