Indication & Signaling
Indication and signaling devices are used to communicate equipment status, operating conditions, and system alerts in industrial and commercial environments. These devices provide visual or audible feedback from machines to operators, or allow operators to interact with and control processes. Common applications include control panels, machinery, automation systems, and safety signaling.
Visual signaling devices include pilot lights, beacons, strobes, and signal towers. These components provide clear, immediate status indication using standardized colors to communicate conditions such as normal operation, warnings, faults, or emergency states. Signal towers and beacons are widely used in industrial automation to improve situational awareness and reduce response time on the production floor.
Audible signaling devices such as buzzers and sounder horns provide alerts where visual indicators may not be sufficient. These devices emit a pre-set tone when energized and are commonly used for alarms, evacuation warnings, machinery start-up notifications, and motion alerts. Together, visual and audible signaling devices support safer operation, clearer communication, and improved system monitoring.
More Information about Indication & Signaling
Pilot lights are devices that provide visual information about the operating status of a circuit. They are normally used for on/off indication, alarm signaling and changing conditions. Pilot lights come in a variety of designs. Indicator pilot lights use LEDs or incandescent lamps as indicating lights in control panels and automated instruments. Pilot lights include a colored lens such as, green, red, amber, white or clear. The colored lens represents the condition of the connected equipment or machine. A green pilot light normally indicates that the system is de-energized or off. A red pilot light normally indicates that a system is energized or on. Sounder horns output an audible signal when a voltage is applied to their input power terminals. The tone is pre-programmed into the circuitry and the sound is emitted when power is supplied. Sounder horns are widely used for generating evacuation alarms in the event of a fire, chemical spill or gas leak. Other applications include machinery start-up alarms, heavy equipment movement, back-up warning systems and movement of doors, barriers and gates.
