Hardwired panels are still king over wireless in commercial buildings

I just finished a 12-unit office complex in Austin where the client insisted on going fully wireless. Six months in and we've already had three repeat service calls from signal interference in the elevator shaft area. In my experience, you just can't beat a hardwired DSC panel with dedicated zones when you're dealing with steel framing and lots of electrical noise. Sure, wireless is faster to install and looks cleaner on paper, but I spent way more time troubleshooting RF dropouts than I would have running 22/4 through drop ceilings. The one time I did a mixed approach - hardwired sensors on the ground floor, wireless on upper floors - that system actually held up better. Has anyone else gone back to hardwired after a string of wireless headaches?

@lunakim I feel you man, but I think it really depends on the building. That elevator shaft thing is real though, and I've had the same headaches with steel frame offices. Sometimes I think people who luck out with wireless just got a good run of luck with the hardware or the building layout.

Troy nailed it. The building itself is like 90% of the wireless game. I've got a buddy who had the same setup in two different buildings. One worked perfect for three years. The other was a nightmare from day one with constant dropouts in the same spots. Turned out one building had some weird steel mesh in the drywall that just killed the signal. People who claim wireless always works just haven't run into the bad luck yet. It's not about the hardware being bad. It's about the building fighting you every step of the way.

Dude I've seen this complaint like a hundred times and it always feels a bit overblown lol. I did a retrofit on a 5 story office park with all wireless Honeywell stuff and it's been two years with zero issues. The elevator shaft thing is real but you just throw a repeater in the mechanical room and call it a day. Maybe your client just got bad hardware or the install team didn't map the zones right.
