Re: Edit/delete posts & edit username whenever desired
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. ...

Re: Simplex 4004 Battery Question
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.

Re: Can older Simplex devices be powered safely using FWR?
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.

Fire Protection Jeopardy
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....
