Potter PE-LFHNR Low Frequency Sounder, Wall, No Lettering, Red

Designed for reliable, code-compliant notification in sleeping areas, the Potter PE-LFHNR low frequency sounder by Potter Electric Signal, LLC delivers clear, life-safety alerts while simplifying installation and ongoing maintenance. This wall-mount sounder supports both T3 (fire) and T4 (CO) audible tones in a single unit, reducing device count and streamlining deployment for facilities management teams. Operating on 16–33V DC (24V nominal), the PE-LFHNR pairs energy-efficient LED technology and strobe synchronization with Potter control panels to maintain synchronized notifications across mixed LED and xenon strobe fields of view.

Measuring just 6.26" H x 4.56" W and finished in high-visibility red, the unit is optimized for hotels, healthcare, dormitories and other high-occupancy spaces where security, surveillance and alarm monitoring are critical. Backed by a 5-year limited warranty, the PE-LFHNR helps reduce total cost of ownership through fewer service visits and reliable performance. For straightforward NFPA-compliant notification that integrates seamlessly into existing fire alarm and security systems, specify the Potter PE-LFHNR low frequency sounder — ideal for retrofits and new construction alike.
