FLPS-7 PSU on MS-9200UD?

This is not a life safety system. Can I use the FLPS-7 to get filtered DC on my MS-9200UD panel?

I kind of doubt it. The MS-9200 only has a connector for a transformer or two which provide 24 volts AC to the panel. I don’t know why Fire-Lite panels have so many different power supply setups. Providing 24 VDC where it is expecting 24 VAC is probably not going to be good for it. Unless you are willing to risk damaging the panel, I wouln’t try it.
