Page 8: Components For Ventilation Operation
1.2.2 Components for ventilation operation Drives The drives open and close windows and/or smoke extraction vents. Ventilator switches The user can operate the window drives using the ventilator switches. Timer switch If a timer switch is connected, windows can be opened or closed at preset times. Rain/wind sensor If a rain/wind sensor is connected, all windows will be closed in the event of rain or strong wind. -
Page 9: Ventilation Operation
Smoke sensor and heat differential If a smoke sensor detects smoke or a heat differential sensor registers a sharp incre- sensor 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. -
Page 10: Fire Alarm
Rain/wind sensor If a rain/wind sensor is installed, the windows will close automatically in the event of rain or strong wind. As long as the rain/wind sensor is active, the windows cannot be opened with the ventilator switch. In the event of a fire alarm, the windows will also open when the rain/wind sensor is active. - Page 11 Stopping the fire alarm You can clear the alarm condition in two ways: • Reset the RWA-Emergency Power Control System. • Reset any RWA switch. When the alarm condition has been cleared, the audible alarm signal stops and the ventilator switches are again useable. 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!
