First off, I removed the "normal" chemical FE's and replaced them with Cold Fire extinguishers.
The chemical ones cake up quickly if not maintained regularly. I now store them in my "rolling garage" to use for BBQ's and campfires if needed.
I have three small ones, SS20's, located in the bedroom next to my side of the bed, one in the kitchen and one in the rear of my Saturn Vue. I have one large one, SS45, located just inside the front entry door.
Here is what they look like.

Then I have one SS-200-AFFF with a 4 foot hose mounted in my diesel engine compartment.
I had one SS-30 Halon mounted in the rear Norcold compartment but when I changed over to the residential Samsung fridge I relocated the SS-30 Halon to my inverter compartment.
I recently bought a new SS-30 for $50 from an owner who never mounted it and I plan to install that one in my Aqua-Hot diesel compartment which is shared with the inverter. I will then have double coverage for that area.
The only place not protected is my Onan 7.5K generator.
Other than the last SS-30 I acquired, I purchased all of my units from Mac. He's a very knowledgeable guy.
