Nev. Admin. Code § 477.080 - "Combination paging alarm system" defined
"Combination paging alarm system" means a fire alarm system designed to provide a general fire alarm and voice communication. The system may be used in whole or in part in common with another signaling system such as voice page or a musical program system if all components are of a type approved by the State Fire Marshal and the nonemergency system does not degrade the alarm and paging functions of the system.
