System Sensor SPRL

Product Overview

The System Sensor L-Series speakers and speaker strobes are designed to simplify installation while minimizing costly ground faults. A plug-in design combined with a universal mounting plate allows installers to pre-wire mounting plates, dress wiring, and verify wiring continuity before the speaker or speaker strobe is connected. A protective plastic cover shields exposed speaker components, helping prevent damaged or nicked wires during installation.

These devices support faster and more reliable installations by providing immediate feedback to confirm proper wiring connections. Field adjustments are easily made using rotary switches for speaker voltage and power selection, along with multiple field-selectable candela settings for wall-mounted speaker strobes. With low total harmonic distortion, the L-Series speakers deliver high-fidelity audio while also providing high sound output suitable for environments with elevated ambient noise levels.
