If you look closely at the scope photo I posted the peaks of the half sine wave are flattened. That probably is due to the MOVs and other components in the power supply and across the NAC. It is possible that the flattened sine wave changes the sound of a mechanical horn. The clipped peaks make the sine wave seem more like DC. With every half cycle going to 0 volts it is obvious there is no filtering in the circuit.
Since nobody answered the 4100+ question, it is a 1,000 point panel. If the panel is part of a network the point total combines local hardware points and network external points. A 4100+ also can provide 2,000 annunciation points. That would be LEDs and switches.

The reason it takes that one only 3 seconds is because when they are in trouble, they don’t reset. I also said on a normal reset. Other people I know who have 9050UDs or NFW-50’s (Notifier equivalent) say that they take around a minute and a half to reset normally. I have an NFW-50 and that’s how long it takes for me every time, regardless of the size of system.
