L-Series Low Frequency Wall Sounder

L-Series low frequency sounders include a variety of features that increase their application versatility while simplifying installation.

L-Series low frequency sounders include a variety of features that increase their application versatility while simplifying installation. They 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.

These devices feature plug-in designs making installations fast and foolproof while virtually eliminating costly and time-consuming ground faults. Installers can also easily adapt devices to a suit a wide range of application requirements with 24V operation and a rotary switch for 520 Hz low frequency sounder tones.

Features & Benefits:
  • 520 Hz ± 10% square wave tone, NFPA compliance<
  • Full candela range plus High/low tone options to optimize current draw for a wide variety of applications
  • Compact and standard, and round ceiling options
  • Field-selectable candela settings on wall units: 15, 30, 75, 95, 110, 135, and 185
  • Rotary switch for high and low, temp 3 and temp 4 settings
  • Plug-in design with minimal intrusion into the backbox
  • Mounting plate shorting spring checks wiring continuity before device installation
  • Electrically compatible with legacy SpectrAlert® and SpectrAlert Advance devices
  • Updated modern aesthetics
Certifications:
