No electricity or batteries are needed—as your door opens, the magnet and contact disc are separated, sounding a mechanical chime.

Just like the bells you hear at service stations, these bells ring when a vehicle drives over the attached hose.

When water contacts the sensor, it triggers a buzzer to alert personnel to a leak or overflow hazard. Frequently used to monitor sinks, pipe lines, tubs, and sump pumps.

Buzzers are UL listed for use in environments where flammable gases, combustible dust, and combustible fibers may be present.

These lights have LED bulbs for years of maintenance-free operation and can be wired as either continuous or flashing.

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 warns workers of hazards even when they’re outside a direct line of sight.

These familiar push-button switches mount to flat surfaces.

Choose from a bell, horn, or chime tone.
