The LSC System essentially consists of a smoke exhaust
control panel equipped with an emergency generator and with an
integrated smoke suction system for the detection of smoke gas in
the lift shaft.
It is specially designed for use in lift
shafts and works on the principle of constant air monitoring. The
air sucked in is examined by the smoke suction system with regard
to the concentration of smoke gas.
In the event of fire, an alarm is immediately
activated and the smoke exhaust flap at the top of the shaft -
driven by an electric motor - opens so that the smoke and toxic
gases can escape unhampered and as quickly.
In addition to the permanent monitoring of
the lift shaft by the smoke suction system, a fire alarm can be
activated by optical fire detectors or by a manual activator and
smoke exhaust - for example in the main evacuation level of the
LSC prevents unnecessary energy loss
as a permanent opening at the top of the shaft is avoided and
therefore uncontrolled ventilation of the building prevented.
Unnecessary loss of heat within the building is avoided as the
smoke exhaust opening at the top of the shaft is permanently closed
and is only opened for smoke exhaust in the event of a fire.
