System Sensor HGWL. Compact Horn.

System Sensor HGWL Compact Horn

The System Sensor HGWL is a compact, wall-mount (or ceiling-mount) horn from the System Sensor L-Series of notification appliances. As a “compact” model designed with a smaller footprint to fit tight spaces (including single-gang back boxes) and blend more discreetly into finished interiors. It is part of the modern L-Series line, which emphasizes reduced current draw, installer-friendly features, and compatibility with legacy systems.

Key Features & Benefits
