Alarms
BiLevel ST 22 carries out a self-test on the sensors when the on/off switch is
pressed. The alarm feature is also tested. If an error occurs during the self-test, an
error message appears on the main screen (see also "7. Troubleshooting" on
page 34).
1. Check the buzzer and the status displays:
Each time you turn the BiLevel ST 22 on, check that you can hear the buzzer and
that the status display lights up.
2. Check the power failure alarm:
Start BiLevel ST 22. Now pull the power supply cable out of the socket; the
display goes out and the buzzer sounds.
Note
BiLevel ST 22 must have been connected to the mains for at least 5 minutes
before carrying out the test.
Turn the unit off after the functional check has been completed by pressing the on/
off
switch.
