Connection:
Ventilation key switch in the
LSF 7000
A ventilation key switch allows only authorised persons
to intervene in the ventilation of lift shaft. For example,
it allows the smoke exhaustion system to be opened du-
ring maintenance work in the lift shaft.
The function of the ventilation switch is subordinate
to the room thermostat and the CO2 sensor. In case of
high temperatures or poor air quality in the lift shaft, the
smoke exhaustion device is open.
Determine the installation location of the ventilation
key-operated switch in consultation with the site ma-
nagement or the operator.

Room Thermostat
Using the bimetal technology with thermal feedback room thermostat, the
temperature in the shaft and/or machine room can be monitored or the
smoke exhaustion system can be opened as required to exhaust the heat.
The function of the room thermostat is secondary to that of the CO2
sensor and superior to that of the ventilation switch.
Assembly
The room thermostat should preferably be installed in the shaft head at
an accessible location in order to measure the temperature in the ma-
chine room or the waste heat of the lift system. The installation is surfa-
ce-mounted or mounted directly on a flash mounting-box with vertical
mounting holes. Range limitation in the adjustment dial.
