The 5522D Horn and 5523D Siren are low current, high performance, high decibel signals for hazardous locations. They are primarily intended for use in hazardous location applications requiring electrical supervision of signaling circuit field wiring. These signals may also be used for unsupervised signaling applications.

They may be mounted on any surface using three bolts.

For use where a high decibel sound is required for alert or evacuation in hazardous locations. Typical applications include signaling for security, fire, power failure, and danger. Ideal for use in factories, flour mills, refineries and paint shops.
