Warn about the presence of smoke with this stand-alone detector.

When visible smoke particles or carbon monoxide is detected, this stand-alone detector alerts you with an audible alarm.

This spray smoke simulates fire conditions to make sure your detectors are working.

The quick-opening valve on these whistles allows manual operation—pull the valve while air or steam pressure is being applied to produce a shrill tone and alert workers.

Buzzers are UL listed for use in environments where flammable gases, combustible dust, and combustible fibers may be present.

Apply air or steam pressure to produce a shrill tone and alert workers. Signal continues as long as pressure is applied.

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

When this horn runs out of air, recharge it with the included pump.

The built-in motor-driven fan in these sirens generates a shrill tone that's audible over long distances.

Just like the bells you hear at service stations, these bells ring when a vehicle drives over the attached hose.
