These whistles operate with the press of a button instead of your mouth, allowing multiple people to use them while lowering the risk of spreading germs.

Arm and disarm these alarms with a programmable code.

Arm and disarm these alarms with a key.

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

A chime announces when someone passes through the infrared light beam and a counter keeps track of each entrance and exit.

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

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

Keep an eye on leaks, overflow, and temperature changes near your equipment, even when you’re offsite.

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

Apply air or steam pressure to produce a shrill tone and alert workers. Signal continues as long as pressure is applied.

Toss these pocket-size air horns when they run out of air.

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

Good for tight spaces where a tower of lights won't fit, these emit three colors from a single lens.

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

This horn has a built-in compressor, similar to that in a car horn, for a louder sound than other lift truck horns.

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

Install these stations throughout your facility for quick access in case of a fire.

Protect your detectors from damage and tampering.

Connect and monitor your fire alarm system.

Warn about the presence of smoke with this stand-alone detector.

An alarm sounds when the cover is lifted.

Provide a signal you can see and hear. Choose from a bell, horn, or chime tone.

Connect these easy-to-use relays to your phone and a light (or other signaling device) and they flash the light on and off when the phone rings.

When your work area has too much or too little oxygen, these detectors alert you with an audible alarm, warning light, and vibrating alarm.

An audible alarm and warning light alert you to the presence of propane.

Use the probe to test the air in a hazardous area before entering. Great for confined spaces.

These detectors trigger a “caution” alert when a small amount of hydrogen is detected and a second “danger” alert if levels continue to rise.

An audible alarm and warning light alert you to the presence of methane.

Place these charts in temperature and humidity chart recorders to document readings over a period of time.

Reduce background noise so you can isolate individual sounds.

Detect lower levels of radiation than our standard detector. Measurements are displayed on an easy-to-read LCD.

These detectors convert ultrasonic waves to an audible sound so you can find leaks.

A stack light and audible alarm alert you when packages, products, and parts are too heavy or too light. Also known as check weighers, these scales verify quality and consistency in packing, parts machining, and other activities.

Measure boiler and furnace combustion efficiency. Also known as combustion analyzers.

Wire contacts to an alarm system to alert when doors or windows are opened.
