System Sensor B501-WHITE 4 Inch Detector Base Bright White No Flange

The System Sensor B501-WHITE is a 4-inch detector base designed without a flange, finished in bright white. As a genuine System Sensor component, it is built for professional life-safety installations where a clean, low-profile mounting aesthetic is required. The flange-free design suits installations where the base mounts directly to a junction box without an exposed trim ring, delivering a streamlined appearance appropriate for commercial and institutional environments. Like all System Sensor bases, it is intended to serve as the mounting and electrical interface between the ceiling wiring and a compatible detector head.
