GENERAL

This category covers national industrial security monitoring stations, which are facilities that have personnel on duty specifically trained to handle signals received from systems covered under National Industrial Security Systems (CRZH).

The listing of a company in this category indicates that the company has demonstrated either the capability of satisfying the requirements for building, equipment, staffing, signal processing, signal retransmission, and record keeping as required in UL 2050, "National Industrial Security Systems," or the staffing, signal processing, signal retransmission, and record keeping as required in UL 2050 and the building and equipment as required in UL 827, "Central-Station Alarm Services."

Periodic inspections are conducted by Underwriters Laboratories Inc. (UL) at the national industrial security monitoring station locations covered under this category to verify continued compliance with the requirements.

UL maintains an Online Certifications Directory that allows up-to-date verification of companies eligible to provide monitoring of national industrial security systems as of the date of the inquiry.
