Appendix VI: Alarm-test procedure
(Authorized personnel only)
To test the alarm limits, the automatic fan control must be overruled, so the fan power can be set
by hand. The entire state of the cabinet will stay unchanged, except for the fan-power. The
required test-code is 7733.
In this state, each 30 second, two short audible signals will be heard, to be remembered at the
initial unsafe mode. After 30 minutes after the last button is touched, the fan returns to its work
mode.
