How can I hook a fire 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. The Paging Input 

Detect Threshold must be adjusted such that the noise floor is 

sufficient to trigger a paging condition and enable ducking, (i.e. 

set the detector just shy of maximum sensitivity – fully counter 

clockwise – so shorted turns off 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?

These fixed line level outputs are for driving other systems or 

"stacking" CP series together for larger applications. The signal 

may consist of paging only, program only or a copy of the zone 

signal. This 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 five conductor wire, 22 gauge or 

larger, will suffice. Use shielded wire for distances greater than 

200 feet.

Can Zone 1 of the CP52S operate in Mono mode?

Yes. The 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 amplifier without connecting a Y-cord.)

When the Priority Signal finishes playing, it takes too 

long for the music to fade back in. Can I adjust this?

Yes. The rear panel Program Priority Release Time control 

can change the interval from five 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. Thus if only a jukebox (P/L4) and other 

line source (L1) are used, the remote volume control will work 

just fine.

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 five wires must be connected for proper operation. 

Also make sure you didn't "flip" 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. These 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. 

Then, re-test all functions of the CP52S. If all works fine 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...

 Phone 425-355-6000, 8 AM to 5 PM PST, Monday through 

Friday.
