BACKORDER

The SpectrAlert Advance HR-LF is a red, two-wire, 12/24 volt, low frequency sounder for wall or ceiling installation

 

SpectrAlert® Advance Low Frequency 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. 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.
