Can we talk about the retired installer in Toledo who flipped me on zone doubling?
I spent my first 4 years running a separate home run for every single contact. Every door, every window, every motion got its own loop back to the can. Clean, easy to troubleshoot, and I would argue with anybody who did it different.
Then last spring I did a 3,200 sq ft ranch outside Toledo. The homeowner was a retired installer named Walt who did commercial work for 30 years. He watched me pull 14 home runs for the windows alone and said, "Kid, you're gonna fill that can up and still be here at dark."
He showed me how he used to double zones on windows in the same room, with a resistor at the end of each leg so a hit still shows up as a trouble on that zone. We finished the whole place in a day and a half instead of three. Panels don't fill up, wire cost drops, and when something trips you just walk the room instead of chasing a number.
I still home run doors and motions. But for window contacts in the same room? I'm a believer now. Walt passed in January and I think about that job every time I'm staring at a half empty can.
Anybody else running doubled zones on windows, or do you all still home run everything? Curious if it bites you on service calls later.
