ITT Key System- Found in the wild at work- Removing it soon.

[Hill Haven Telephone Company]

Found one in the wild at my work.  I work at a thrift shop that helps the community.  found an ITT cover on a shelf.     They want to install ceiling mounted speakers,  looking up in the steel rafters,  i notice house cable 25 pair,  Tracked it to the electrical closet.    So here it is an ITT KSU.  going to clean up the backboard and document everything.  pull the ITT and bring it home to my collection.  and set up a nice little PA System/Music system for the store.     Also found those 2 spools of cable.

Sadly, these are all disappearing.  They used to be as common as dirt.

Nice find, looks like you got a you got a dial intercom that supports touchtone, and the power supply takes modern fuses that are easy to find and has a 30hz ringing generator, so you could connect up all your old phones not just key phones.

if it an ITT 501KSU, I had one once, tried to sell it, wound up scrapping it out, no one wanted it. saved all the cards, and PSU. damned thing weighted a ton... glad its gone, had no use for it since I have the WE equivilent of the unit in storage to replace the 1A1 system I'm running if that thing ever dies....
