The North Las Vegas Fire Department is the agency that provides fire protection and emergency medical services for the city of North Las Vegas, Nevada. All 911 calls go through the muti-agency Fire Alarm Office (FAO) located at the Las Vegas Fire & Rescue Department Headquarters. The Fire Alarm Office serves as dispatch for the NLVFD as well as the Clark County Fire Department and the Las Vegas Fire & Rescue Department. The use of Computer-aided dispatch allows for the determination of the nearest unit, even if that unit is from a neighboring department. Thus an engine from the Clark County Fire Department may respond into North Las Vegas mutual aid if the system determines that they are closer.
