L-Series Low Frequency Wall Sounder Strobe

System Sensor L-Series low frequency sounder strobes are rich with features guaranteed to maximize profits with lower current draw and modern aesthetics.

The L-Series offers the most versatile and easy-to-use line of low frequency sounderstrobes in the industry. With white and red plastic housings, listed for wall mounting, L-Series Low Frequency can meet virtually any application requirement. The low frequency sounder strobes were 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. Like the entire L-Series product line they include a variety of features thatincrease their application versatility while simplifying installation. All devices feature plug-in designs with minimal intrusion into the back box, making installations fast and foolproof while virtually eliminating costly and time-consuming ground faults.To further simplify installation and protect devices from construction damage, L-Series uses a universal mounting plate with an onboard shorting spring, so installers can test wiring continuity before the device is installed.

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
  • Field-selectable candela settings for wall units: 15, 30, 75, 95, 110, 135, and 185.
  • Rotary switch for High/Low, Temp3, Temp4, and Continuous settings
  • Plug-in design with minimal intrusion into the back box
  • Mounting plate shorting spring checks wiring continuity before device installation
