Industrial signaling devices provide critical audible and visual alarms that enable fast operator response to changes in machine status, production faults, or safety conditions. Whether mounted on equipment or built into panels, these devices help reduce downtime, improve workplace safety, and keep operations running smoothly.
Summit offers a comprehensive range of Schneider Electric signaling devices, including tower lights, beacons, buzzers, and panel indicators. Designed for seamless integration into control systems, these indicators help monitor equipment performance in real time, alert operators to issues, and streamline maintenance across production lines, plant floors, and outdoor systems.

What’s possible with Schneider Electric's Signaling?
What’s possible with Schneider Electric's Signaling?
- Clear Status Indicators – Multi-color tower lights and panel indicators provide instant visual feedback to show machine state, fault conditions, or operational readiness.
- Audible Alerts – Buzzers and sounders emit distinct tones to notify personnel of alarms, start-up sequences, or safety shutdowns in high-noise environments.
- Modular Configuration – Stackable light and sound modules simplify custom tower builds without increasing inventory complexity.
- Compact Panel Options – Flush-mount indicators fit into standard panel cutouts, offering clear signaling in space-constrained cabinets or operator stations.
- Rugged Environmental Ratings – Select models meet IP66 and NEMA 4X requirements for washdown, outdoor, or dust-prone environments in industrial facilities.
- Flexible Voltage Support – Available in 12V, 24V, 120V, and 240V AC or DC to meet the needs of varied equipment and control architectures.
- Standards Compliance – Devices meet IEC 60947 and UL Type standards for use in industrial machinery, building systems, and OEM panels.
