Volume increases as voltage increases.

Lights combine high-visibility strobes with a buzzer that warns workers of hazards even when they’re outside a direct line of sight.

These lights have LED bulbs for years of maintenance-free operation and can be wired as either continuous or flashing. The beep or buzzer alerts workers when they're outside a direct line of sight. Lights meet IP65 for protection from washdowns.

Get notified about equipment issues even when you aren't around your machines. These lights connect to your computer via Ethernet, allowing you to set up email alerts when there is a problem with a machine, server, or conveyor. The buzzer can emit both continuous and pulse tones—pulse tones alternate on/off to draw greater attention than continuous tones. Lights have an LED bulb for years of maintenance-free operation.

Use a computer to program colors, lighting patterns, and sounds to communicate a variety of status conditions, material levels, and cycle times—these stack lights have 21 colors and 11 sounds. Since you set up each signal from your computer, you can update them without changing hardware or wiring. These lights let you remotely monitor equipment because they don't need to be installed near the equipment they're monitoring as long as these lights are on the same Ethernet network as the equipment. For widespread communication across your facility, set as many as eight of these lights to mirror the signals of one main light.

Connect these stack lights to your computer with an Ethernet or USB cord. They can either connect to power from their terminal block or, for a simpler setup, use Power over Ethernet (PoE). They have digital inputs, so they can also receive electric signals from your programmable logic controller (PLC) or microcontroller.

Mount them to a flat surface using the included fasteners. Add a base for additional mounting options.

Good for tight spaces where a tower of lights won’t fit, these emit three colors from a single lens. They have an LED bulb for years of maintenance-free operation. The buzzer alerts workers when they're outside a direct line of sight. Rated NEMA 4X for washdown applications.

The revolving motion of the light makes these more visible than flashing lights. The bell alerts workers when they're outside a direct line of sight.

Provide a signal you can see and hear. Mount these signals up to 25 ft. away from your phone and they’ll alert you when someone calls with a strobe light and an audible signal. Choose a tone and program your signal accordingly. Use a telephone cord (sold separately) to connect these signals to your wall jack.

Note: For use with one-line analog phones only.
