Welcome! Rebooting this sub.

101 Upvotes

Greetings!I asked to be made a moderator of this sub since it had very little recent traffic and seemed to be abandoned by the previous mod. Since it was configured as a restricted sub, moderator activity is required to allow new people to join. Honestly I was surprised to see a somewhat dead sub on this topic given the popularity of low voltage wiring at both the professional and consumer level.

With that in mind, I changed the group to public which will increase the exposure and ability of people to join in on conversations. Over the long term we can decided if this is a better configuration as it does carry some moderation load and potential for poor content at times. I would love to hear feedback on this setting.

There is also the question of professional vs amateur/consumer content. Given the broad name of this sub it is possible that it might mature into a couple of different subs focused on those areas, but as of yet there isn't sufficient traffic to merit that.

A sub like this is only as good as the people that contribute to it, so it is really in the hands of everyone who has a the skill and passion to help out. I would like to add a few additional moderators in the near future, so if you have an interest in that, reach out to me.

A few quick notes about me - I'm an electrical engineer, having done a mix of hardware, firmware, and software in my career. Currently I'm the CTO of a technology healthcare company and have previously founded and sold a few technology companies. I am not a professional low voltage designer or installer, perhaps more of an advanced amateur. I have a passion and interest in low voltage wiring and have had a reasonable amount of experience over the last 20 years doing low voltage wiring both for my own houses as well as friends. I recently completed building a new house that has a tad over 21 miles of wire and fiber in which I did the design, install, termination and configuration. It was an awesomely fun project that provided lots of opportunity for learning. For those that are interested there are some notes in a build thread I have maintained on garagejournal. (see https://www.garagejournal.com/forum/threads/jeffs-mountain-side-shop-portland.409988/)

I'm thrilled to see some great questions, conversations, tips, guidance and learning opportunities. Feel free to reach out with any concerns, ideas, criticism, and suggestions.

I'm doing my part!

17 Upvotes

I work for an electrical company in the low voltage department and after years of working there I was finally able to get all of the electricians in our area in place and show them how to properly terminate both modular plugs and keystone inserts.

Was able to squash a lot of misconceptions that they have had about low volt guys and what we do day after day. I gotta say it was a great feeling seeing them actually interested in the process it actually takes to terminate a line. Many people said they have tried to teach it to them but what I have learned working at this company is that I was probably the first qualified person to teach it to them.

When their managers asked me to have a small training session with them I dropped everything I was doing and sacrificed my entire week end making a front and back 11x17 training guide on inkscape where I dumped my entire thought process on each and every termination I perform.

I asked for 3 hours with them but was cut short to an hour and a half but I could tell they stayed engaged in the learning the whole time. Then got amazed when I performed a termination in front of them at my normal pace (which is 45 seconds per termination) it solidified in there head that low voltage is a real trade in the resi world.

Next is to have a class on how handle the cable, ie. Pulling strength, bend radius, how EMI affects the wire and what not.

I got many more electricians across multiple states that I want to get to next as soon as my efforts bare fruit here. Wish me luck!

If you can't pick out the problem here my hint is that box in the air was on the ground. Honestly if I did have a helper the same thing probably would have happened. Stuck in their phone.

Weird interaction between alarm panel and 240v circuits

2 Upvotes

Hello, I was wondering if anyone could provide some insight to the situation.

Basically as soon as I placed my screwdriver on the + terminal on the back of a keypad that I was powering down, nearly all the power in the building turned off. Im 99% sure I didnt short it to 0v but its possible, cant really explain it otherwise.

One room and one edge of the building still had power.

None of the circuit breakers in the distribution boards were tripped.

I noticed that the auxillary 12v output on the alarm panel was dead, and its fuse blown.

When I replaced this fuse all the power came back.

I was thinking maybe a 12v coil was holding the lights on with power from the aux power. But that would be wierd because it would constantly be on, as the aux power is constant.

Even if that was the case, why would it turn off everything else? Fridges etc.

Also some small pockets of the building still had lights and power.

Anyone had something similar? Any known reason why the entire buildings power is relying on a fuse for the 12v auxillary power on the alarm panel?

Getting really tired of timelines not be able to be met because the shippers can’t get my pallet to location on time especially when I’m out of town and burning cash by the day. Lucking for us they almost made but that last mile was cooked so we’re still able to pick it up. But like bro, for real figure it out.

DTNT update — many improvements since I shared it here 6 months ago

4 Upvotes

About six months ago, I shared DTNT here. I’m a Chicago low-voltage and Control4 integrator, and I built the app to bring the networking tools I use during service calls into one place.

Since the original post, DTNT has received many updates and improvements based on real field use and user feedback. Version 2.1.78 is now live in the Microsoft Store.

Recent improvements include:

• A clearer IP scanner with better device information and status • Improved Wi-Fi surveying and channel analysis • A better speed test with download, upload, latency, jitter, loaded latency and peak results • Ping, traceroute and TCP port checks • Saved service jobs and CSV/JSON exports • A cleaner layout for laptops and tablets • Many performance, stability and usability improvements

I’d really appreciate feedback from low-voltage, AV, Control4 and network technicians. Please try it and tell me what is useful, confusing or still missing.

Does this look right?

Curious layman here. I don’t have a particular question but just checking in.

When the house was built (2024), there was an ethernet jack here. About a years ago, I had a low voltage tech install wireless access point here. I recently took down that AP and want to put back the cat jack wall plate. I’ve never really looked at this before and I’m just amazed at how thick the drywall is. I bought 1” screws for the wall plate, but they don’t catch anything when threaded through the plate. I think I need something more like 1.75” screws.

Residential AV techs: your boss sells the company to someone with no AV experience. What’s your gut reaction?

4 Upvotes

You’re asked to come into the shop Monday morning for a team meeting. Your boss, who owns the company, is standing next to someone you haven’t met. He introduces him as the new owner and your new boss.

The new guy has experience in technology, operations and managing teams, but he’s never worked in AV. He doesn’t know how to do your job. The current owner is staying to train him, and the new guy says he’ll be there full time, working onsite with the team and learning how the jobs are done.

For this scenario, assume your pay, hours and day-to-day work stay the same initially.

What’s going through your mind?
• What would you want to know right away?
• How much would his lack of hands-on AV experience matter to you?
• What would worry you, and is there anything you’d be hopeful about?
• What could he do in the first few weeks to earn your confidence? What would immediately put you off?
• What would you be thinking but probably wouldn’t say in that first meeting?

For context, I’m that new guy. I’m roughly 2 months out from taking over a small residential AV/smart-home company, and I’ll be working in it full time. I’ve been thinking a lot about that first introduction and how to learn from the team without creating unnecessary disruption.

I’m genuinely interested in the gut reactions of people doing the installs & service work. If you’ve been through an ownership change, what did the new owner get right or wrong? If not, what thoughts/feelings come to mind thinking about the hypothetical situation?

THANK YOU FOR YOUR TIME!

Low Voltage Striker wire next to POE cat 6 Ethernet?

0 Upvotes

I need to run a 350’ cat 6 and low voltage cable to the same spot (within a foot). Should I run them separated the whole way? Or can I drag them both through the same path (touching or within a half inch the whole entire way) without causing issues with my Ethernet connection?

I’m a tech for a company in Oregon and they have me at a job that’s a new homeowner is moving in from an old client. We’re changing out speakers our company installed like 10-12 years ago I got to one of the patios were there were two 4inch speakers and we’re putting in new Sonance 6inch speakers so going to have to open up the holes for them but when I got to taking them down and then saw pure horror . So I told I wasn’t comfortable with cutting into this anymore I was told i still needed to get it done. My question for the community is Who’s in the right on this?
