What kind of smoke or fire alarms are required?

I think you might be referring to what might be required by the Underwriting in securing a home mortgage loan? Typically Fannie mae and Freddie mac (the majority of all conforming and high balance loans completed) want you to have working smoke alarms on each floor and a carbon monoxide detector as well.It is wise to have a smoke alarm in every major room in the house. One could have a carbon monoxide detector on each floor but lenders generally only require one be installed.
