I had this customer in Phoenix who called me out 4 times in 3 months with a DSC system that kept triggering for no reason. After swapping it out for a Vista 20p with a new motion detector, I haven't gotten a single callback in 6 weeks. Has anyone else had better luck with one brand over another for stubborn false alarm houses?
I was on a job last Tuesday at a dentist office in Tampa and saw three different motion detectors screwed in sideways. The guy before me probably thought it looked cleaner that way, but those things have a specific detection pattern printed right on the housing. I had to climb up and rotate all three because the coverage was all messed up. Has anyone else run into installers who just ignore the arrow on the back?
I was checking out a townhouse complex that just went up near my shop. The builder used wireless sensors on every door and window, and the whole place was clean with no wires anywhere. I've always been a hardwired guy because I thought wireless was too unreliable. But seeing how fast they installed everything and how neat it looked made me rethink things for certain jobs. Anyone else had good luck with wireless in new construction?
I did a retrofit in a 1920s building in Philly last year where every wireless sensor dropped signal through the plaster and lath, but hardwiring took three extra days of fishing cables. Now I'm on a similar job and the customer wants wireless to save money. Is the reliability tradeoff worth the time savings on these older structures?
I was setting up a system for this 40,000 square foot warehouse outside Cleveland. Kept going back and forth between wired sensors for reliability or wireless for speed. I ended up going wired because the building had open ceiling trusses that made running cable easy. Took me and my helper about 3 days longer than wireless would have, but the signal is rock solid with zero interference from all those forklifts and metal racks. The customer was worried about the extra labor cost, but now they haven't had a single false alarm in 6 weeks. Has anyone else dealt with this choice in a big open space like that?
Was running a new zone in a building near Wrigley and hit a live 120v line behind the drywall. Now I use a non-contact voltage tester on every wall before I drill - saved me from getting zapped.
I was in Nashville last week doing a service call for a system that kept showing low battery trouble. Pop the panel open and the battery is swollen and leaking acid all over the circuit board. Customer said they had a power flicker during a storm 3 days ago and the system never recovered. That battery was only 2 years old. I looked closer and the terminals were corroded because the battery vent was clogged with dust. This is the third time this month I have seen batteries fail after voltage spikes. If you are not checking those terminals and vents during routine maintenance you are going to end up chasing ghost troubles. Has anyone else noticed more battery failures after recent weather?
I dropped $400 on a smart panel from a popular brand thinking it would simplify things, but the app crashed during three different installations and I had to swap back to a hardwired DSC setup on site. The cloud system just couldn't handle the constant connections we need for commercial sites, and I wasted a full day troubleshooting. Has anyone else had better luck with wireless panels, or am I the only one who thinks they're overpriced junk?
Had a job last week over in Maplewood, a brand new house where they wanted wireless sensors on every window... 32 windows in total. Got to window 28 and the hub just stopped syncing entirely, no error code or anything. Spent three hours on the phone with tech support before realizing the homeowner's WiFi mesh was on the same frequency as my panel. Has anyone else run into interference issues with those new mesh systems?
He saw me loading up a bunch of wireless sensors and just shook his head, said 'son, you're gonna be back here in 18 months replacing batteries on half of those.' Then he started rattling off stats about false alarms from low battery chirps that get systems yanked. Has anyone else noticed a drop in reliability with newer wireless gear compared to hardwired systems from 10 years ago?
I was on a job site last Tuesday and the general contractor told his boss that anyone who uses wireless sensors instead of hardwiring is just cutting corners. He was talking about a system I installed last month at a 2,400 sq ft house and now I'm second-guessing my work. Do you guys run into this kind of pushback from other trades or is wireless pretty standard now for residential?
Was reading a thread last night where a guy said his glass break sensors kept going offline in a steel warehouse. I always thought wireless was fine for any indoor spot, but he mentioned the metal framing basically kills the range. Made me wonder if I should stick with hardwired for commercial garages and metal sheds even if it takes longer. Anyone run into range problems with wireless in metal framed homes or buildings?
I spent almost 6 hours on a job in Austin last Tuesday trying to figure out why a Vista 21iP was losing connection every 45 minutes. Turned out the customer had a new wifi extender that was conflicting channels with the panel's radio. Has anyone else had interference problems with these cellular communicators?
Last month I was doing a new alarm install for a house near Camelback Road in Phoenix. The homeowner said everything was fine, walls were solid. I'm running wires in the living room and I tap the wall near this big framed movie poster. Sounded hollow. I pulled the poster off and there's a hole big enough to fit my whole arm through. Someone had cut out a section of drywall to run wires and just covered it up. No patch, no nothing. Homeowner said he didn't know about it but I'm pretty sure he did. Had to stop everything and spend 2 hours patching and mudding before I could even drill. Has anyone else run into homeowners hiding structural issues or damage behind decorations? How do you handle it without making the customer mad?
I had a job last month at a warehouse in Cleveland, 40 foot ceilings. Client wanted full coverage on the floor. I wired four motions in parallel like I always do, but the first false alarm from a space heater had me pulling my hair out. My partner said he swears by series wiring for big rooms to cut down on nuisance trips. But then you lose the individual zone reporting on the panel. Which way do you guys go for open layouts with lots of environmental noise?
I was on a retrofit in a new build in Phoenix last month and saw the crew before me had shoved cat5e right through a raw stud hole with no bushing. I pulled it out and there was already a nick in the jacket from the rough edge. That kind of thing can short out your entire zone after a couple years of dust and vibration. Anyone else make it a habit to throw a $0.50 grommet on every hole you run through?
I was setting up a system in a new construction house outside Austin last week and the wireless touchpad kept losing connection to the main panel. Turns out the builder had metal mesh in the drywall that killed the signal. How do you guys handle RF interference from modern building materials?
I used to swear by those old DSC 1616 panels for basic residential jobs. They were cheap, easy to flash, and I could bang out a install in under 3 hours easy. Then last winter I had a call back on a system I put in back in 2021. The panel was totally dead, no power, no backup battery holding a charge. Customer was pissed cause their house got broken into while the system was offline. Took me a week of chasing wires to find out the board had a cracked trace from age. Now I only use the newer PowerSeries Neo panels even if they cost $80 more. The old stuff just cant handle the heat cycles in attics around here in Phoenix. Has anyone else seen old panels fail like that after just 3 or 4 years?
I've been installing alarm systems for about 4 years now and always just drilled into studs assuming they were safe, but last Tuesday on a job in an older house I nicked a wire that was running right through the middle of a 2x4. That could have been a real disaster or even a fire, and it made me wonder - how many of you actually use a stud finder with wire detection before every single mount?
Spent 3 hours tracing what I thought was a bad resistor on a panel but it turned out to be a spider nest in the motion detector. Has anyone else had bugs or critters set off zones and waste your time?
I had this DSC panel that kept triggering the alarm at 3 AM every other night for a month, and I swapped out the motion sensor, the window contacts, even the battery. Turns out a tiny spider had built a web between two terminals on the main board, causing intermittent shorts. Anyone else run into weird critter-related issues inside alarm panels?
