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 2, Groups F and G, and Class III, Division 2 hazardous locations. You can select up to three programmable tones, each corresponding to a different warning. If multiple signals are triggered at once, only the highest priority signal will sound.

The built-in motor-driven fan in these sirens generates a shrill tone that's audible over long distances. Sirens emit a continuous tone. They have a shock- and corrosion-resistant housing, so they're approved for use on U.S. Navy ships.

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