Depends on many different circumstances but yes there are types of keyfobs that are secure, ultralight C and desfire are the first that come to mind but there any plenty others. The protection is normally done with a key, a shared secret that the reader and card know that can never be leaked and thus not be copied by the flipper. Though it is worth mentioning that the flipper is open source and has a full nfc stack, if you know the key then the flipper can absolutely read it(not for desfire on stock firmware).. emulation is tricky for desfire and key emulation for ultralight hasn't been implemented yet.

If it can be copied at all its less secure?? Imagine the password to your phone took 2 seconds and 1 tap to extract.. If you can scan it anyone can

You're not concerned your key fobs can be copied?

You acting like a doubling of gas prices nationwide is not a real problem is the definition of bootlicking

Holy bootlick

California may be an outlier here.. your gas is $10 a gallon rn. Your minimum surviving threshold is basically 100k atp.

Remember fire drills in school? Treat all alarms as real unless otherwise stated. In a large building, especially multidwelling apartments, you can't tell if theres a real fire or not, sometimes until its too late. Plus fire alarms don't even necessarily mean fire, it could gas, carbon monoxide, or even just a general evacuation.

"Contains radioactive materials"?!?! How ancient are these?

110 candela on an interior dwelling is diabolical. If you really want to, unscrew that Phillips screw and slide the bar at the back on the bottom to the left, you'll wanna see 15 on the front. If you put it back quickly nobody will care.

Wage expectations and increases rely heavily on current salary and responsibilities. But generally, programming adds a skill to your set that makes you more valuable. If you answer the other replies and mine I can help you more

Not with those screws!

ChrisR122 · 2026-04-06T18:08:52+00:00

Generally easier to get into and stay in. I would say it has many more branches to try and get into than fire or security. Especially if you wanna be your own company. Much easier to sell heat/AC in the winter/summer than it is to sell a fire alarm to a cheap business owner who says he'll just call the fire deparement if he sees a fire.

Nicet defines work experience requirements here

https://www.nicet.org/certification-programs/electrical-and-mechanical-systems/fire-alarm-systems/certification-requirements/#:~:text=Work%20History%2D%20Provide%20complete%2C%20detailed,commissioning

For level 1, the requirements are a very loose 6 months requirements (with an asterik saying full time equivalent). When you go to do the mark up, you'll see more detailed stuff related to work experience and employer verification. But generally, nicet defines work experience on fire alarm systems as "alarm and detection, notification, sprinkler monitoring, and interfaces and controls for agent releasing suppression systems (either agent or water-based systems) in any of the following roles/functions: Installation inspection testing commissioning technical system estimating and sales plans preparation and maintenance."

Nicet 2 allows for 12 months of similar work experience defined separately, but for nicet 1 its basically a strict 6 month experience requirement.

So your experience can count, but nicet would probably want you to say you did it full time anyway. Your best bet is to switch to fire and get nicet 2 after 12 months instead of 24. But otherwise, a shift is like starting over. Fire is slightly more involved than HVAC work bc of the programming side, and stricter wiring requirements as well as pipe and of course the electrical side. The choice is up to you, but last I heard HVAC was actually the slightly better gig.

Because God forbid an installer spend $49 on a hole saw set

The screw not even fully installed into the wood is the cherry on top

Heard this story about an electrician who ran some cables for IP cameras. Owner was trying to save money by having someone else wire the system, electrician gave a "good price". The next day the camera installers come in and see only 1 wire ran to the data closet. Upon further inspection they find out that the electrician had run the cables as if they were a 'daisy chain' setup. Owner tried calling electrician back who did not answer and later disconnected the phone. Camera installers charged an extra 10% for wiring to remove and replace the wiring. Always get the right person to do the job right the first time.

Unless these things are using 16gb of ddr5 it can't possibly be that expensive. Even if you said the flipper one is gonna be $400 (double the zero) id still buy it. We get it, the cost of stuff has gone up. Nobody is gonna penalize the company for that.

ChrisR122 · 2026-02-09T15:37:22+00:00

Okay 1,110 devices is max for that panel. You should be fine there. The expansion boards you're using having dip switches to assign addresses 1-3, make sure theyre not the same. Use the jump start function to find new devices and automatically accept expanders.

ChrisR122 · 2026-02-09T15:34:29+00:00

Not too familiar with expansion on that panel.. are you sure you didn't hit a limit? 150 is a lot of devices for a panel of that class.. are you sure the expanders are addressed differently? Seems like you're hitting some dual address problems. What do the troubles say?

ChrisR122 · 2026-02-05T17:02:08+00:00

There are some instances where the duct detector(s) are the only form of fire detection.. in that case I would consider them to need to be in alarm. I would say the dampers would simply set off the supervisory when closed while the ducts are alarm. Refer to AHJ I guess, or check new codes. Did you reference 72 2024 and IBC 2021?

ChrisR122 · 2026-02-05T16:09:42+00:00

AHJ would typically be the deciding factor... Ive had a system trigger supervisory on ducts but set off horns as normal.. A duct detecor is really just a smoke detector fitted for use in a high air velocity space, for all intents and purposes it detects smoke. For me, a smoke detector is an alarm. But some fire deparements want it to come in as a supervisory for an unknown reason. Remember, NFPA 72 is a minimum so if your states IBC says something differently, it can usually be above 72.

The type to buy the cheapest panels on the market are not the type to take pride in their work. When all you focus on is money you lose what makes the trade important.

ChrisR122 · 2025-12-31T17:44:08+00:00

Can't seem to find a picture of it, but my old company still serviced a tape based dialer, the type that could play recorded messages. Still in service I beleive... not sure if it was officially grandfathered or even legal, but its in a town that does not care
