System Sensor offers a Web-based Voltage Drop Calculator that allows users to quickly and easily lay out audible/visible notification device circuits using the company’s notification appliances. The step-by-step process allows users to accurately calculate the voltage drops along a notification appliance circuit by analyzing each device on the circuit and determining if enough operating voltage is available at each device location. The calculator will calculate wire resistance, circuit distance, filtered vs. unfiltered panels, candela settings, and distances between devices. The free calculator can be downloaded at www.systemsensor.com /voltdrop/index.html and used from a Mac or PC without Internet connection.
