Low Frequency Sounder from System Sensor


System Sensor has launched new low frequency notification appliances that meet the NFPA 72® requirements for all commercial sleeping spaces that begin in 2014.

“For people living in states and regions that have adopted the 2010 or 2013 edition of NFPA 72, all new commercial sleeping spaces will be required to utilize an audible device that produces a low frequency tone centered around 520 Hz effective January 1, 2014,” says Rebecca Peterson, System Sensor Product Marketing Manager. “Many of our customers are wondering how they are going to meet this requirement. Our new SpectrAlert® Advance low frequency notification appliances have them covered.” Why the change to the code? “Studies have shown that a lower frequency is more effective at waking sleeping individuals, including individuals with mild to severe hearing loss, when compared to the 3 Kilohertz tone found in residential smoke alarms,” continues Peterson. “We see these devices being used most often in spaces like hotel rooms, dormitories, assisted living and nursing home facilities just to name a few.” The first low frequency sounders and sounder strobes on the market that integrate directly with fire alarm control panels, these notification appliances include all the same features and benefits as the rest of the market-leading SpectrAlert Advance line, including a plug-in design and onboard shorting spring that simplifies installation and reduces costly ground faults.
