System Sensor says its SpectrAlert Advance Low Frequency Sounders and Sounder Strobes are the first notification appliances to meet the new NFPA 72® 2010/2013 low frequency requirements for certain new 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.

These devices were designed to easily integrate into the panel’s notification appliance circuit (NAC) line and provide audibility and tone requirements needed to awaken individuals. Like the entire SpectrAlert Advance product line, these low frequency sounder and sounder strobe devices include a variety of features that increases their application versatility while simplifying installation. All devices feature a plug-in design and universal mounting plate, making installations fast and foolproof while virtually eliminating costly and time-consuming ground faults.

To further simplify installation and protect devices from construction damage, the SpectrAlert Advance universal mounting plate utilizes an onboard shorting spring, so installers can mount the plate and test wiring continuity before the device is installed. The low frequency sounder and sounder strobe devices are easily retrofitted into existing SpectrAlert Advance notification applications while also delivering greater flexibility for the new code requirements.
