Carbon Monoxide Alarms and Use of Dual Technology Ruling

Board of Fire Prevention Regulations (BFPR) Issues Ruling

Below is a ruling from the Board of Fire Prevention Regulations (BFPR) regarding Carbon Monoxide Protection and the use of dual technology. This advisory was necessary to clarify some confusion and to provide a means for compliance for both the traditional 110 v and low voltage systems that are available in the market place.

The BFPR has always wanted a clear way to distinguish between fire and carbon monoxide detection and notification. This advisory ruling does this in a manner consistent with the BFPR’s original intention of clear distinction of type of alarm. In doing so, it is the intent that the alphanumeric display indicates a distinctive alphanumeric message (digital or embossed) for the alarm condition of smoke and carbon monoxide. This message is to use the words smoke or carbon monoxide and not a zone designation, such as zone 1.

If you have any further questions please contact the Code Compliance and Enforcement Unit at (978) 567-3375 or in Western MA at (413) 587-3181.
