I would recommend you remove the personal recommendations because of liability. Always reference an agency as the source of the information. Example, “Per the NFPA all bedrooms should have blah, blah, blah.”
P.S. My 4 bedroom home ~1500 sq.ft has:
2 co detectors, hard wired & interconnected.
7 smokes, hard wired interconnected.
2 smokes, battery and centrally monitored.
1 heat detector in garage, hard wired, but not yet interconnected.
1 - 1A10BC extinguisher (in kitchen due to small size for easier handling).
1 - 3A40BC extinguisher, in garage.
3 - 8A70B foam extinguishers on each level of home, no C rating since only rated to 240 volts.
1 - second floor escape ladder.
1 - hardwired escape lights in basement.
? - flash lights on each floor
? - etc.
So I love when a client asks if getting smoke detectors are necessary.
