Connectors
Figure: Connectors on Audio Unit – Cabin Compact (New Type)
Rotary Switch
There is a glass-covered rotary switch on the audio unit front side. Use the switch to
set ALARM/CANCEL (normal/inverted input) and audio unit type (cabin, cabin roof,
cabin bottom, shaft bottom).
Safety
Make sure that the minimum button isolation distance is 1.5 mm and
breakdown voltage is 1,500 V. The button contacts may not be connected
to any other circuits. If you cannot meet these conditions, use voltage
control.
You can use the switch on the audio unit front side or closing/opening
button connected to the ALARM CONTACT connector or both of them if
necessary.
Note
The ALARM button on the cover keeps functional even if an external
button is connected.
