System Sensor is pleased to announce the next phase of our L-Series product line with the availability of low frequency (520 Hz) sounder and sounder strobes. The L-Series offers the most versatile and easy-to-use line of low frequency sounder and sounder strobes in the industry.

With white and red plastic housings, listed for wall and ceiling mounting, L-Series low frequency devices can meet virtually any application requirement. The low frequency sounder and sounder strobes are designed to address the NFPA 72 sleeping space requirements that require a low frequency notification appliance that operates within frequency range of 520 Hz ± 10% and is of a square wave tone.

Significant power supply savings

These new products provide a consistent look with the previously released L-Series product line while offering the following enhancements over the legacy SpectrAlert Advance line:

  • Up to 40% lower current draw for significant power supply savings
  • Unmatched versatility to fit any application by offering:
    • Wall, ceiling and compact models
    • Rotary switch for High and Low, Temp 3 and Temp 4 tone settings
    • Full candela range to optimize current draw
  • Compatibility with existing SpectrAlert and SpectrAlert Advance notification appliances for retrofit applications
