RWA Control Unit
LSF 7000
Point-type smoke detector with relay in base
The smoke detector must be mounted horizontally under
the ceiling at the level of the main evacuation level, near
the lift door, but at least 50 cm from the nearest wall.
If the LED in a smoke detector is lit, this automatic de-
tector has triggered the alarm. Triggering is reset via the
“Close Reset” button in an HSE button or via the “ Reset
/ EMERGENCY CLOSE” button in the control centre (see
“Displays and Operating Elements”).

Smoke detectors in the main destination stop
There is an “extended static fire control system” according to VDI guide-
line 6017 integrated into the

System. The lift control
system must be designed to activate this function.
The specified fire exit of the lift shaft (the exit which is automatically
accessed in case of fire) is monitored by a smoke detector. If this smoke
detector has been activated in case of fire, the lift shaft will be shut down
on another specified floor with open doors. The smoke detector in the
main destination stop is connected to the detection line of the shaft
smoke detectors and simultaneously triggers an RWA alarm of the lift
shaft smoke exhaustion system.
The detector is connected via the internal relay contact in the base
directly to the lift controller, which initiates the evacuation travel when
triggered.

Ventilation Key Switch
The
LSF 7000
system allows the smoke exhaustion unit to be used for
ventilation purposes as well. A ventilation key switch or a potential-free
switch contact of another control device can be used for this purpose. By
programming the Control Unit, it is possible to program various ventila-
tion functions such as time-controlled automatic closing. The
LSF 7000
Control Unit is pre-programmed with an automatically time-controlled
ventilation function.

If the time-controlled ventilation function de-
activated, the air quality in the lift sha ft may
deteriorate, especially in summer time.
n
ote
Approximately every 8 hours, the smoke Exhaus-
tion system is opened for approx. 10 minutes to
ensure regular ventilation of the lift shaft. This
function can be deactivated via the
LSF 7000
Software . The ventilation function is blocked in
case of any malfunction.
