About Sound Levels

To choose an alarm or speaker that’s loud enough, first determine the decibel (dB) rating of background noise.

About Hazardous Location Environmental Ratings

The horn-shaped design focuses the sound projection toward listeners.

Note: For speakers with several wattage options, the higher the watts, the louder your speaker will be. If you're connecting several speakers to one amplifier, the total watts of all speakers should not exceed the maximum wattage of the amplifier.

Hazardous Location Horn-Shaped Speakers

These speakers are rated for environments where hazardous material is present. The horn-shaped design focuses the sound projection toward listeners. Speakers are NEMA 4X rated for protection from corrosion and washdowns.

Hazardous location environmental ratings indicate whether manufacturers have included safety features in products to facilitate their safe use in a hazardous environment. Before selecting a product for a hazardous location, ensure it is rated for your environment. See About Hazardous Location Environmental Ratings.

Dual Horn-Shaped Speakers

The dual horn-shaped design focuses the sound projection toward listeners in two directions.

Note: Each speaker has several wattage options—the higher the watts, the louder your speaker will be. If you're connecting several speakers to one amplifier, the total watts of all speakers should not exceed the maximum wattage of the amplifier.

Listen to music while keeping your phone out of harm’s way. Tough enough for the jobsite, these Bluetooth speakers are rated IP54, so they resist dust and splashing water. They also withstand drops of up to 10 feet. Take calls on speakerphone using the microphone. Use the buttons on top to answer or hang up, as well as to play, pause, or change songs. The mounting strap has a hanging hole and magnet—loop it around a pipe, hang it from a nail, or stick it on a steel surface.

Stay informed and entertained while you’re on the job. These radios have a roll cage, so they’ll keep working if dropped or knocked off a workbench. You can plug them in when you’re near an outlet, or use batteries to take them anywhere.

Radios with a Bluetooth connection work with your smartphone or other Bluetooth-enabled device to play music wirelessly. When plugged in and used with rechargeable batteries, these radios let you charge the batteries without needing a separate charger.

Radios with NOAA weather band reception receive seven frequencies for local weather alerts and hazard information.

Radios resist water splashed from all directions. IP64 radios are also dust tight, so they’re better for dirty, dusty, and sandy jobsites.

Pest Repellent Ultrasonic Speakers

Plastic

Steel

For simple and humane indoor pest control, these speakers play sounds that drive away rodents and crawling insects.

Plastic speakers emit ultrasonic (inaudible) frequencies powerful enough to protect an average-sized room from pests.

Steel speakers emit both ultrasonic (inaudible) and sonic (audible) frequencies powerful enough to protect up to 3,500 sq. ft. of indoor space from pests, including bats and other small animals.

Bird Repellent Speakers

Drive away birds without traps or chemicals. These speakers play naturally recorded bird distress calls and predator cries to deter them from settling in the area. Maximize disruption to birds by programming these speakers to vary their calls at different times, and minimize disruption to yourself by setting your preferred hours for when they’re turned off.
