These make great doorbells when used with a push button.

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

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

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.

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

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

Arm and disarm these alarms with a programmable code.

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

Lights combine high-visibility strobes with a buzzer that 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.

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

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

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

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

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.
