Does any one know if the External Paging Contacts Black/Blue pair and Auxiliary Ringer Contacts Red/Slate can handle ether 10VAC or 24VDC voltage or does it have to be a dry contact?

I have a 1a2 Key project in mind and I need a relay to activate when ether page or a ringer goes off from the Nortel side.


Thanks
 
Paging Contact:
Outputs audio to an amp/speaker
The KSU is like a microphone - two leads outputting

External Paging Contact:
A Dry Contact - Normally closed
The KSU is like a light switch - one lead intercepted
Primarily used to turn off (mute) music when a page is made or to some amps that require it.

Aux Ringer:
A Dry Contact - Normally open
The external source is like a light switch - one lead intercepted

The voltage form a PS goes to your external device.
Any relays from an external device go to the KSU

Maybe somebody can add/confirm all that.
