Residual risks
In case of regular use:
Entrapment can occur when the fire resistant door closes upon fire alarm. The
mechanical failsafe closing of the fire resistant door does not take into account the
possible presence of persons. The probability of a person becoming trapped is very
low due to the low speed of the closing movement and the optical and acoustic
warning signals.
When a gravitational self-closing (failsafe) system on our products / the fire resistant
doors, 2 optical and 1 acoustic signals with autonomous power supplies will be
provided in accordance with standard EN 12604-2000 / EN 13241-2016;
It is strictly forbidden to place goods/materials in the "run" of the closing and/or opening
door leaf.
In case of maintenance:
During maintenance/inspection of the fire resistant door the installation must be
disconnected from the power supply and ensure that it remains disconnected from
the power supply. Due to voltages in the installation there remains a risk of electric
shock.
Upon inspection of the movement system, crushing hazard may occur when the door
comes/is in motion.
