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

Boasting the best sound quality of our wall-mount speakers, these produce clear public address announcements and background music.

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.

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.

Stay informed and entertained while you’re on the job. Plug these radios in when you’re near an outlet, or use batteries to take them anywhere. All can be used in the rain or other wet environments.

IP54 and IP64 radios are the best choice for dusty and sandy jobsites.

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 with a roll cage keep working if dropped or knocked off a workbench.
