- Follow up to the test of this system - there was a horn/strobe not working. Turns out it was wired backwards but still passing supervision through so no troubles were thrown. This place recently completed a nearly two-year renovation and many, many hands were in this system, so this kind of stuff wasn't really a surprise. Enjoy!
Wow, that's an old panel. I thought only the newer ones had removable terminal blocks. Great video!
Yep, 1999-ish. I'd personally love to run that panel over with a bulldozer.
@@brettman273 XD I wish that panel had the ability to synchronize the alarms. Legitimately got my eardrums pierced by watching 8 minutes of that!
The people that were groaning is pretty funny lol
Yeah it was right at lunchtime, and they had sat through 10 minutes of that thing making noise already lol.
Wow! Unless the Red was wired backwards in the panel the Red is Always Positive! The Black is Always Negative! I have seen in some old panels reversed polarity. Very odd but it is out there in the field. Also HS outside sometimes getting shorted with water seeping in. This will cause a ground fault or dead short. The growning is them tired of hearing the 75 to 100 DB level HS screeaming thru out the building. I get this sometimes when the clients can't take the loud noise thru a walk thru of the building. Best to put system on Walk Test to avoid having them moan. Most of the time I don't bother putting it on Walk Test. They already know its going off.
Agreed, Red always positive. But it's easy to screw it up when it's the 50th one you've wired that day... Or if you're tracing a problem and breaking into circuits to check resistance and continuity. I've definitely made problems worse before fixing them many times by fat-fingerings wires the wrong way. Let the magic smoke out of a few older panels and components even. It happens....
What is a walk test?
Gotta love the lack of door bypass hotkey options. Can that old firewarden panel do it?
Probably, but a screwdriver solved the problem in four seconds. For a twice- per year test, that is sufficient for me.
@@brettman273 Yeah. Plus its always about the big picture, don’t know why I didn’t see hotkeys as just a “convenience option”.
Nice Notifier AFP-300 or 400
It is an AFP-400.
