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.

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.

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.
