L-Series Outdoor Compact Wall Horns

L-Series Outdoor Weatherproof Horns are rich with features guaranteed to cut installation costs and times with its lower current draw and modern aesthetics.


The System Sensor L-Series and L-Series with LED Outdoor platform offers the most versatile and easy-to-use line in the industry with lower current draw and modern aesthetics. LED lighting technology offers significantly lower current draw compared to older Xenon bulbs across a full candela range. This improves design flexibility for notification appliance circuits (NACs) while also reducing power supply requirements allowing for simpler and lower cost installations. L-Series with LED can meet virtually any application requirement, including indoor, outdoor, wet, and dry applications in temperatures from −40°F to 151°F.

Flexible design options meet virtually any application requirement: wall or ceiling mount, red or white color choices, and LED color lenses for distinctive visual signaling. In addition, installers can easily adapt devices using field selectable candela, using rotary switches.

The L-Series and L-Series with LED line is developed to simplify 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. The universal mounting plate includes an onboard shorting spring, so installers can test wiring continuity before the device is installed.
