External Paging on Norstar MICS 12 32

"the page port off the MICS has no audio coming out on it"
Then the page port is blown.
To be sure, did you connect a working butt set to the page port and have somebody page through it or enter digits to get the tones?
Is the Amp cable 100% snug in?
Did you try another 25pr Amp cable?



"Do we need some external device ??"
Depends...
A small site you could loop a couple of self amplified horns.
Any bigger you use an amplifier with amplified horns and speakers.

"Can we set up paging on a line port ???"
Yes you can use a trunk port if you have a spare.
It is limited because you cannot page through phones at the same time or use different zones.
You can however add ceiling speakers in the hallways etc and/or add a zone controller module.

Check to see what type of horn, ie 70 volts and 1 pair or 2 required.
I prefer Bogen myself, one pair for power and audio, no need for a bloody shelf for the amp.

i WILL RUN THE LINE PORT TO A BOGAN WMTI-MATCHING TRANSFORMER TO GET IT TO 600ohm-then loop to 4 amplified horns -see what happens...

line ports need voltage to modulate the voice for audio.
WMT1A will most likely not work but you can try to take a 24V DC power supply and loop that into series with the speakers and that should work.

Ask if they need music or aux ringer, Bogen TPU15a or alike.
