Just realized hardwired panel zones are way more reliable than wireless for large commercial jobs

I spent last week pulling my hair out on a 40 zone retrofit in a Denver warehouse because the wireless sensors kept losing signal through concrete walls. After swapping a third of them over to hardwired contacts, the false alarms stopped completely and the customer finally signed off. Has anyone else run into range issues with wireless in commercial settings?

Oh man, you hit the nail on the head. I had almost the exact same nightmare on a 60 zone job in an old office building downtown. Those concrete walls and metal framing just kill wireless signals dead. I ended up running hardwired contacts for almost half the zones after three straight nights of false alarms that made the security company look bad. Hardwired is more work upfront but it saves so many headaches on commercial jobs. The customer trust is worth the extra labor every time.

Same issue here with a 40 zone job in a brick building last year @kelly_coleman61. Wireless just couldn't handle the signal drop off from the elevator shaft and thick interior walls. Swapped half the zones to hardwired and the false alarms stopped that night. Hardwired is a pain to fish but it beats the hell out of losing a security contract over bad signal.
