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

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....
