where should i look ?
Which kind of fire-lite?
Better question is, what kind of parts are you looking for? Pulls, detectors, modules, panel parts, etc.?
Fire-Lite MS-25 PSU
That’s their 25-point addressable panel, right? For starters, their addressable BG-12LX pulls will work. As for smokes, you’re limited to their HFS-protocol detectors. LiteSpeed devices will not work, IIRC.
I believe he means he needs a power supply unit (PSU) for the MS-25.
Find a local distributor, Chances are there is adi or tri-ed around you. I would use a bad power supply as a reason to go to a 9050.
