Update Your G1 SCBA Sound Pattern

The 2013 edition of NFPA 1982 instituted a standard PASS alarm sound for all PASS devices. This was aimed at improving firefighter safety and interoperability on the fire ground. Following the release of this new sound pattern the NFPA Committee heard comments from firefighters that the new standard alarm sound was harder to hear than older versions.

To answer the demands of the fire service a more effective sound pattern has been identified and incorporated into a TIA (Tentative Interim Amendment).

MSA G1 SCBA users can easily activate this new sound pattern by following the four steps below.

1. Request Tag & Label

A Tentative Interim Amendment is tentative because it has not been processed through the entire standards-making procedures of NFPA. It is interim because it is effective only between editions of the respective standard (i.e., 2013 vs. 2018). A TIA automatically becomes a public input for the next edition of the standard; as such, it then is subject to all procedures of the standards-making process.

The TIA has been by issued by NFPA with an effective date of December 21, 2016, which requires all new PASS devices certified to NFPA 1982-2013 Edition to include the new universal PASS alarm sound.

It is important to understand that the issuance of the TIA will not impact the certification of SCBA presently in the field. Current SCBA that have been certified to meet the NFPA 1982, 2013 Edition standard will continue to maintain their certification as being compliant to the standard and are not required to be updated. All new SCBA manufactured after December 21, 2016, will be required to meet the new universal PASS alarm sound as specified in the TIA.
