Smoke sensor and heat differential
sensor
If a smoke sensor detects smoke or a heat differential sensor registers a sharp incre-
ase in temperature, the fire alarm is triggered.
See Section 1.4, Fire alarm, for details on how to clear the alarm.
Alarm signal (optional)
The RWA-Emergency Power Control System transmits an external alarm signal if the
fire alarm is triggered. This can be used, for example, to trigger an audible alarm or
the alarm can be relayed to the fire station.
External fire alarm system
If your RWA-Emergency Power Control System is connected to an external fire alarm
system, this can also trigger the fire alarm.
See Section 1.4, Fire alarm, for details on how to clear the alarm.
Fault signal (optional)
The RWA-Emergency Power Control System transmits an external signal in the event
of a fault. This can, for example, be connected to a warning lamp.

The windows are divided into ventilator groups. For each ventilator group, there are
one or more ventilator switches which can be used to open or close all the windows
in that ventilator group at the same time.

The opening and closing of the windows is indicated by LEDs on the RWA switches

The signal on the ventilator switch only applies for the windows in its ventilator group,
while the signal on the RWA switch refers to all the attached ventilator groups.
Therefore, the yellow Window Open signal lamp

tinguished until the windows in all the ventilator groups in its alarm group are closed.
