Planning information
ATTENTION
Property damage due to increased heat in the event of a fire.
The increase in heat that occurs inside the enclosure in the event of fire
must be taken into account.
This must also be factored in when designing the layout.
To facilitate more detailed planning, an example is provided below of the
temperature increase in the event of fire, according to the Standard
Time-Temperature Curve, in an empty housing at a height of 2/3 in the FB23LE
fire protection enclosure:
