Here is an article for determining whether a Notifier or a Fire-Lite panel puts out Filtered or Full-Wave Rectified (FWR) power.

Here are the definitions of the two by how a lot of people know them.
How does a mechanical horn sound on...

• Filtered: Smooth
  FWR: Raspy

Here are some notes about FWR, and why FWR is so bad and should not be used anymore:

• FWR uses more current, meaning that less devices can be used on the circuit.
  All simplex panels put out Filtered power, and therefore Simplex signals starting with the horizontal 4903 series signals (4903-9219, 4903-9238 etc) and all TrueAlerts, will get damaged and will eventually die if used on FWR.
  Early versions of the Wheelock LED Exceder have been found to short circuit randomly on FWR.

And now, the table. All blank spots are products that do not have an equivalent in the other brand.
