I was working in an adult care home last week when I had to remove a smoke alarm that was in my way. When I pulled it off the mount, I discovered it was wired to line voltage with 4 conductor telephone wire. Upon investigation I found the entire system was wired and interconnected with the same phone wire, plus no boxes, just flying splices tucked away in the walls behind each unit!
Before I submit a bid for rewiring the entire system, which would require a lot of cutting into walls (this is a residential structure) I thought there might be a low voltage interconnected system that I could use with the existing low voltage 4 conductor wire.
Anyone know of such a system?
