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.).

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.
