Good morning ~
We are using the MOH/Paging module as part of our Mitel 2000SX Light system to provide paging.
We have 100+ buildings that could potentially need speakers (1 for most, 2 for some) and hope to use newly installed phone pair to take the signal from two different demarc points to the various buildings.
Can anyone recommend a particular amp/speaker setup for this? Any advice would be most welcome!
Thanks,
Jeff

Wow, 100 plus buildings. That's rather an ambitious project.
I'm not sure I would recommend audio over twisted pair for that extensive a system. What distances are we talking about?
Hate to say it but this might be a good application for an IP based distribution to each building. How is your networking between these buildings handled?

Some up to 2000 feet.
The only available connections between buildings in the phone wiring. We have brand new pairs to each building so that's a plus.

I'm not a big believer in powered speaker systems, but with only 1 or 2 speakers per building it might be just the thing.
Something by Valcom maybe. For the long runs you might have to double up the pairs.
Is this an "all call" configuration or do they want this zoned?

Some up to 2000 feet.
What's the longest combined distance from the beginning to end? I assume that some if not all buildinge will be bridged off this run?

This will be an "all zone" system that is only used for the most severe of emergencies.
We have two nodes and I was thinking of having the amplifiers in each node. The buildings home run back to their respective node so that is where the distance comes in.

So you are saying that the 2000 ft run is from the farthest node to the PBX location?
Also, what does your wiring consist of? You say it is brand new, what kind of cable?

Right. Everything home runs from the building back to the node. Pair 1 in Node 1 corresponds to Pair 1 in Building 1.
It's Cat3 phone wire to all homes.

Well, I think you may have put the cart before the horse by installing wiring then trying to figure out what to do with it. You probably could have saved a bundle on wiring. You may want to look at Valcom Encompass. I believe it's an IP based system with amplified Valcom speakers, it is what you are looking to do. Give them a call. -Hal

The wiring actually had to be installed - old wire was in bad, bad shape.
Using extra pair for the paging system is add-on to something already in-place.
