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.
