How can I hook a re alarm control relay to the unit for
complete muting?
Connect a normally closed relay across the Paging Inputs
(plus [+] and minus [-]) so they are shorted together. When
an alarm condition exists and the coil becomes energized, the
contacts open and the short is removed. e Paging Input
Detect reshold must be adjusted such that the noise oor is
sucient to trigger a paging condition and enable ducking, (i.e.
set the detector just shy of maximum sensitivity – fully counter
clockwise – so shorted turns o the green LED and open causes
it to illuminate). Set the front panel Ducker Depth control fully
counter clockwise so no program material is audible during an
alarm condition.
What are the EXPAND OUTPUT connections for?
ese xed line level outputs are for driving other systems or
"stacking" CP series together for larger applications. e signal
may consist of paging only, program only or a copy of the zone
signal. is output can be used for music on hold as well as
zones not needing level adjustment (i.e. rest rooms, entryways
and similar areas).
What type of wire can I use to connect the remotes?
For runs up to 200 feet any ve conductor wire, 22 gauge or
larger, will suce. Use shielded wire for distances greater than
200 feet.
Can Zone 1 of the CP52S operate in Mono mode?
Yes. e CP52S has a Zone 1 Mono Switch on the rear
panel.
When Zone 1 of the CP52S is in Mono mode, which out-
put LEFT or RIGHT should I use?
Either output will provide a summed LEFT plus RIGHT
mono signal. You can use both LEFT and RIGHT outputs
simultaneously when needed, (like when you want to run two
channels on a power amplier without connecting a Y-cord.)
When the Priority Signal nishes playing, it takes too
long for the music to fade back in. Can I adjust this?
Yes. e rear panel Program Priority Release Time control
can change the interval from ve to twenty seconds.
I just want a remote volume control, not source selection.
Is there a way to do this?
All selection and level is done either on the front panel or
at the remote; never both locations. Connecting just a VR1 to
the CP52S remote control terminals will allow level adjustment.
However without a source selector, the unit will default to source
one. If the PRIORITY / L4 INPUT automatic switching is
enabled, then the unit will select the L4 signal when present and
L1 at any other time. us if only a jukebox (P/L4) and other
line source (L1) are used, the remote volume control will work
just ne.
I just installed a unit and don't get audio. Or I hooked up
the ZR1 source remote but can't get any audio. What hap-
pened?
First check all the wire connections at both ends of the
remote. All ve wires must be connected for proper operation.
Also make sure you didn't "ip" the wiring at one end of the
cable...it happens. Also note that once the front panel RMT but-
ton is pressed "in" both the PROGRAM SELECT and LEVEL
functions only work at the remote. ese two front panel con-
trols are disabled when the RMT switch is engaged. For testing,
push the RMT switch and make sure it's in the "out" position.
en, re-test all functions of the CP52S. If all works ne now,
the problem lies in the remote or wiring to it.
I can't get the page microphone to work. What am I doing
wrong?
First check all the wire connections at both ends of the mic
cable. Next be sure to set the PAGING INPUT MIC/LINE
switch correctly on the front panel. Once you have the setting
correct, turn up – clockwise – the INPUT TRIM control and
see if you can light the OL indicator when you yell into the mic.
Now adjust the DETECT THRESHOLD to get ACTIVE to
illuminate. If all this checks out, it's time to follow the Recom-
mended Calibration Procedure on page 10.
If the above options don't answer your question, or it's
urgent...
