Device description

Visual Signal Device

Device intended to communicate warning, alarm, or information signals by means of light.

A visual signal device uses a single-color or multicolor light source to communicate the state of a machine, installation, or process. It may operate continuously, flash, or use predefined visual patterns.

Principal parameters include light-source technology, lens color, luminous intensity, luminous flux, viewing angle, flash-frequency range, number of visual patterns, and brightness adjustment.

For multicolor devices, supported colors and independent indication channels are also relevant. Selection further considers supply voltage, control method, mounting, and environmental conditions.
