The i4 Voltage Calculator determines the voltage required for your i4 CO/smoke detection system so you can calculate your power supply and battery requirements. Whether your installation is 12 or 24 volt, 2 or 4 wires, this tool quickly calculates your voltage needs based on the number of i4 combination detectors and compatible i3 detectors you enter (up to 12 devices per i4 module).
