Your customers deserve to roam freely throughout their house, armed with the comfort and confidence that they'll hear the alarm if their home security system gets triggered. Drawing just 1/3 the current of standard security sirens, the Piezo Dynamic Siren lets you add indoor sirens to your customer's basement, garage and other peripheral areas of their home—all on the same alarm panel. They're loaded features that can make for easy installation, too, such as easy-to-wire terminal blocks, hinged case covers and elliptical mount holes.
