Low frequency sounders and strobes
System Sensor SpectrAlert Advance Low Frequency Sounders and Sounder Strobes meet new low frequency requirements for certain sleeping spaces.
System Sensor SpectrAlert Advance Low Frequency Sounders and Sounder Strobes meet the new NFPA 72 2010/2013 low frequency requirements for certain new sleeping spaces. 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. 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.
