Klaxon Motor Driven SirenWeatherproof
The DUPLO series is a motor driven weatherproof siren. This siren’s unique output signal may be pulsed on and off to achieve a wailing tone. The siren's sound is produced by a multi-bladed, nylon impeller which pulls air through openings located on the front of the unit and pushes the air out through radially positioned vents.
