NFPA 72 Model for MFVN Compliance

Managed Facilities-based Voice Networks and the National Fire Code – A Summary of New Rules Approving the Use of Non-Traditional Telephone Lines For Fire Alarm Monitoring


• Isn’t 24-hour standby power required since NFPA requires it, and "POTS" lines provide it? No. NFPA has allowed 8-hour standby power for voice lines since the 1980’s, when telcos began using 8 hour batteries in the remote terminal equipment that provides dialtone to homes and commercial buildings. Today, over 50% of all telco lines, nationally, are provided from these remote terminals.

• Is UL listing required for voice equipment attached to alarm equipment? Yes. NFPA 72 requires that both communications and fire alarm equipment "be UL listed for its purpose". On-premises voice equipment is UL listed under Telecommunications (UL® 60950). Fire alarm equipment is UL listed under Fire Alarm Systems (UL® 864).

• How can AHJs or alarm companies confirm that a voice provider meets these requirements? These parties may contact the voice provider to confirm the service conforms to all NFPA requirements.

CableLabs® has been actively collaborating with NFPA since 2005 to address this important issue.
