Product DescriptionUPG 15 Watt 2-Tone Outdoor Horn Siren- SS-15P
This siren uses new patented piezo technology to acheive the same high sound output levels as conventional sirens using only a fraction of the current draw. This reduces the power requirment from the control panel and the standby battery. Installers prefer the much lower weight of the new sirens, making them easier to install.
