I'm trying to get an M1G to speak (from Output 1) through an On-Q/Greyfox inQuire Cat-5 based intercom system. The beauty of this would be that the voice prompts emitted from the M1G would be distributed nicely throughout the house via the existing intercom system. I realize I can add external speakers to Output 1 on the M1G to accomplish the same thing, but using the existing intercom system would be a cleaner and more aesthetically pleasing option.
I called On-Q and they gave me the pin-outs to the intercom system and I am able to easily use my tone generator to put a tone on the intercom speakers. Yet when I hook the intercom speakers to Output 1 on the M1G I get an expansion module failure within 30 seconds or so. I checked to see if the intercom was passing voltage back over the speaker wires and there is none.
My guess is that there is an impedance problem. The intercom system uses a standard 8 Ohm speaker but when I take the reading off the intercom distribution module that I'm trying to tie into I get a reading of 10.1K Ohms.
Any suggestions on how I can make this work?
