12VDC Mute Trigger In
When 12VDC is applied to the Mute In, the
system will fully mute all zones in the system.
The connections for the trigger are made using a
two-conductor cable with 1/8" male mini-plug
jacks. The tip is positive (+) and sleeve is nega-
tive (-). This allows for the connection of an exter-
nal paging or muting device. Note: The CAS44
will not accept a paging audio input; however, if
used with an independent paging system with
12V trigger out, that can be used to trigger the
mute.

supplies 12VDC when the first keypad is turned
on. The 12 VDC is removed 5 minutes after the
