I finally stopped hating on wireless sensors after that school retrofit
I've been a hardwire guy for 15 years, always talked down about wireless stuff. Then I had to do a 40-room school in Columbus where fishing wire would've taken a month. Checked the battery specs on the new Honeywell 5800 series, 7 year rated life, and the signal strength held at 300 feet through block walls. We finished in 6 days instead of 3 weeks and the customer was thrilled. Any of you guys switched over for commercial work or still think hardwire is the only way to sleep at night?
