Quickly plan and model notification appliance circuits (NACs) using the entire line of SpectrAlert^® Advance appliances with the Voltage Drop Calculator. System Sensor has completely redesigned this user-friendly tool as a stand-alone application that users can download to their computers.

The Voltage Drop Calculator allows users to create NACs from a variety of appliances, including legacy devices, to meet nearly any application requirement. Users can easily and accurately calculate the voltage drops along a NAC by analyzing each device on the circuit and determining if enough operating voltage is available at each device location.

The Volt Drop Calculator is an Adobe^® AIR^® application that is loaded with powerful and useful features, including the ability to save and share each project as needed. Users decide how to handle files: They can start fresh with a New Project, or go to an Open Project (saved project). Job details and user preferences can be saved for each project, and all design work is accessible on one page.

Graphical elements in the tool visibly display changes as they are made. A “used amps” bar, for example, shows how much power each circuit is using. The Device Listing and Device Ruler visually produce the NAC as it evolves. Users can move devices simply by dragging and dropping them.

The tool calculates voltage drop based on wire resistance, circuit distance, filtered vs. unfiltered panels, device settings and distances between devices. Users can build a NAC to print or e-mail to team members or the Authority Having Jurisdiction. The printing feature accommodates multiple types of submission forms and five print options.

The Voltage Drop Calculator can be downloaded at systemsensor.com/volt.
