These make great doorbells when used with a push button.

Buzzers meet NEMA 4X for protection and corrosion resistance in washdown environments.

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.

Horns are UL and C-UL listed for indoor and outdoor use in Class I, Division 2, Groups A, B, C, and D; Class II, Division 2, Groups F and G; and Class III, Division 2 hazardous locations.

When this horn runs out of air, recharge it with the included pump.

These horns have disposable canisters that can be replaced when the propellant is gone.

The quick-opening valve on these whistles allows manual operation—pull the valve while air or steam pressure is being applied to produce a shrill tone and alert workers.

The built-in motor-driven fan in these sirens generates a shrill tone that's audible over long distances.

This alarm plays a recorded message when it detects someone passing within 6 1/2 feet.

Arm and disarm these alarms with a key.

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

The revolving motion of the light makes these more visible than flashing lights.

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.

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.

Indicate forward or reverse motion with these bells. They mount directly to a vehicle's wheel hub, without switches or wires.

These horns produce a sound loud enough to be heard in industrial settings.

These alarms beep loudly and repeatedly when a vehicle moves in reverse.

In addition to an audible signal, these alarms flash a high-intensity strobe to draw attention during fire emergencies.

Operate low-voltage devices that require less than 48 volts, such as doorbells and buzzers.
