Here's the law from the California Health and Safety Code concerning inspections of schools:

13146.3. The chief of any city or county fire department or
district providing fire protection services and his or her authorized
representatives shall inspect every building used as a public or
private school within his or her jurisdiction, for the purpose of
enforcing regulations promulgated pursuant to Section 13143, not less
than once each year. The State Fire Marshal and his or her
authorized representatives shall make these inspections not less than
once each year in areas outside of corporate cities and districts
providing fire protection services.


In my rural area school fire alarms are local only and are not, as a general rule, wired to a reporting agency or private alarm system.
