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

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

Attract more attention with a strobe light as well as an audible alarm. Arm and disarm these alarms with a key.

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 from corrosion and washdowns.

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 and combustible dust 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 II, Groups F and G, and Class III hazardous locations.

Sirens can emit both continuous and pulse tones—pulse tones alternate on/off to draw greater attention than continuous tones.

These make great doorbells when used with a push button.

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.

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

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.

With no moving parts as well as sealed electronic components, this horn is built to last even in wet conditions.

Listen to machine performance to detect mechanical problems and leaks.

Identify a variety of small leaks quickly and access hard-to-reach areas with the flexible probe.

The aerosol can dispenses a foam that bubbles over pressure leaks and forms a crater over vacuum leaks, providing quick and reliable leak detection, while saving time and energy costs.

These detectors are fluorescent green. Bubbling action at the source provides quick and reliable leak detection, saving time and energy costs.

Bubbling action at the source provides quick and reliable leak detection, saving time and energy costs.

When a tiny amount of liquid makes contact with the pH patch, it changes color to indicate a leak.

The clear plastic center permits easy visual inspection.

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.

Mount these bells up to 25 ft. away from your phone and they'll alert you when someone calls.

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

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.

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

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

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

Place these indicators anywhere you need to detect and warn about the presence of carbon monoxide. The circle in the center darkens when carbon monoxide is detected and returns to its normal color when exposed to fresh air.

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

When these detectors sense high levels of hydrogen sulfide, they alert you with an audible alarm, warning light, and vibrating alarm.

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

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

These levers have a bolt that locks your door when the alarm is armed.
