Hi all,
I am looking for a install manual or documentation for an old push button intercom.
The mfg is Emerson Electric with a Rittenhouse sub-division and a model # M9034.
Just found out that the company was bought by Nutone some time ago which may be a help.
I have googled this to death and nothing. Every time I feel like I am getting close I hit a wall.
Anyone know of or have a clue on a source for this system. It is a rather simple system but some wiring was changed by the building owner and now it no workie.
The biggest piece of info that I need is whether it is to operate on AC volts or DC Volts. Any help or insight would be appreciated.
TIA
Les
