Sounders and Sounder Strobes are the first notification appliances to meet the
new NFPA 72®2010/2013 low frequency requirements effective January 1,
2014 for all commercial and certain residential sleeping spaces. The Low
Frequency Sounder bases meet the new NFPA72® 2010/2013 low frequency
requirements as well as the new NFPA 720® 2012 carbon monoxide low frequency
requirements effective January 1, 2015. Studies driving these requirements have
shown that a lower frequency is more effective at waking individuals in a fire
event, including those with mild to severe hearing loss.
