External Switch
Normally, the CIA-1000 indicator light and relay are
actuated by call signals on the intercom channel. The
CIA-1000 may also be modified to actuate the light and
relay using an external, user-supplied switch. See Figure
for location of the switch connector.
Mounting
The CIA-1000 can be wall mounted using the slotted holes
in the bottom of the case.
The front-light version can be installed in an equipment
rack using optional Audiocom rack mounts.

outlet and into the
12-15 VDC
power jack on the
back of the CIA-1000.

System Select
switch to the "in" position for
Audiocom or the "out" position for RTS TW.

• Audiocom, the position of the switch does not
matter.
• RTS TW intercom system: select either channel 1
or channel 2 as desired.
