Honeywell 6270 ADT
Purchased a home with a Honeywell 6270 ADT on the wall in the master bedroom. Did not get the code from previous owners and factory reset codes aren’t working. I had to take it off the wall and disconnect the speaker as the only way to get some silence. I’d love to keep the system as it is already set up with door, window, occupancy, fire, monoxide, and probably other sensors I’m forgetting to mention. Should I just pay someone to come out and fix it or would I be able to do so myself.
A little background:
I believe the control panel is in the basement, but the previous owners didn’t know the code to it so they flipped off the breaker when they sold us the house. Unfortunately the breaker also controlled our sump pump and electrical components to our plumbing. Well we had shit storm yesterday (literally) when sewage started coming up from the toilets, showers, and bath tubs. Long story short (kinda) we had to flip the breaker back on to have the plumbing working normally. Now the system is blaring and the only thing I was able to do is disconnect the wire internally for the speaker itself, there is no company name for installers for an installers code and anything simple like the address and zip code don’t work neither do the manufacturer recommended reset codes.
