The Fire Panel Forums

Mod staff can definitely look into it, but if I recall correctly, those limitations are in place because of issues the old mod staff had in the past: Editing/deleting posts used to be used to 'change the story' in the past. We had a user get into an argument with numerous members, as well as staff. ...

I have a Simplex 4004 panel. The battery voltage reads 9.2 vdc output after disconnecting the batteries. The problem started with a fault indication. The panel will not reset. I sent a request to Simplex for a schematic so I could diagnose the problem. Simplex never responded. Does anyone have a sc...

You can check by using a Spectralert Classic, I believe. It's one of the few electronic horns that have an audible difference between filtered DC and FWR. On filtered DC, the horn will sound smooth, at about an A-flat. On FWR, it will sound slightly scratchy at a lower pitch, about a D. This video f...

The older horns should be okay, but they will sound scratchy. The strobe should be okay too. Now, this is just conjecture on my part, but I think the reason why newer Simplex alarms don't like FWR power is that they lack the circuitry to compensate for the rapidly oscillating voltage. Presumably add...

Correct!

This firefighting agent can be abbreviated with the acronym "AFFF".

We miss you, Alex. Thank you for almost 36 years of Jeopardy.

Incorrect! Also, needs to be in the form of a question

We've had question-and-answer quiz topics on this forum before, but I don't think anyone's ever flipped it around! So now, instead of answering the question, you'll have to ask the right question that goes with the answer! And if you've got any ideas, go ahead and ask (or rather, answer!) them here....

For a demo system, anything from 18-gauge to 14-gauge hookup wire is sufficient. Real systems generally use 14-gauge FPL or FPLR wire.

Yep, that's a National Time 641! Pretty rare, I've never seen one in person before.
