Central Station Fire Service

Fire alarm systems are supervised by a commercial entity serving multiple customers. Fire alarm signals are recorded and acted on by trained operators. Requirements in NFPA 72 address these elements of service:

  • System installation at protected premises
  • Signal monitoring
  • Retransmission of signals and associated record-keeping
  • Testing
  • Maintenance
  • Runner service
  • Certification

NFPA 72 allows for Central Station Service delivery by either a single full-service entity, or through a contractual partnership between a monitoring company and an alarm service-local company.

Central Station Burglar Alarm Service

Central station systems operation is under joint control of the owner and the central station.

Runners are on duty at all times and are dispatched to investigate any unauthorized entry of protected properties. Local law enforcement may also be dispatched.
