Low Frequency Alarm Meets NFPA 72 Requirements

System Sensor has launched new low frequency notification appliances that meet the NFPA 72 requirements for all new commercial sleeping spaces, which will be required to utilize an audible device that produces a low frequency tone centered around 520 Hz effective Jan. 1, 2014. The SpectrAlert Advance low frequency notification appliances meet the requirement.

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.

The low frequency sounders and sounder strobes integrate directly with fire alarm control panels. They include all the same features and benefits as the rest of the SpectrAlert Advance line, including a plug-in design and onboard shorting spring that simplifies installation and reduces costly ground faults.
