Stopping the fire alarm
You can clear the alarm condition in two ways:
•
Reset the RWA-Emergency Power Control System.
or
•
Reset any RWA switch.
When the alarm condition has been cleared, the audible alarm signal stops and the
ventilator switches are again useable.
Resetting the system fully
The way in which the RWA-Emergency Power Control System is prepared for another
alarm is dependent on the cause of the alarm:
•
If the fire alarm has been triggered by an RWA switch, reset this RWA switch (see
next section).
•
If the fire alarm was triggered by a smoke sensor or a heat differential sensor,
reset the RWA-Emergency Power Control System (see next but one section).
•
If the fire alarm was triggered by an external fire alarm system, please ensure that
the alarm signal from this fire alarm system is switched off.
Resetting an RWA switch
1. Open the RWA switch using the key.
2. Release the black pushbutton (2) using the slider (1).
3. Reset the fire alarm by pressing the green Close button "ZU" (3).
The windows and smoke extraction vents Close again, the alarm is cleared and
the RWA-Emergency Power Control System is reset.
4. Replace the broken glass (4).
5. Lock the RWA switch again.
GEFAHR
If the system is not fully reset (the red fire alarm LED is still lit), the system will not
function properly if a new alarm is triggered!
➮
Always reset the system fully after an alarm.
