Strikethrough indicates a value below the device's minimum voltage at indicated location and wire gauge
These calculations assume a worst-case source voltage as measured by UL with the batteries depleted to 20.4 volts. Under
AC power and for most of the drain cycle of the batteries, the circuit voltages will be substantially higher and thus, would
support a greater number of devices. A device's minimum operating voltage is derived from the UL-requirement that it
operate within a Regulated Voltage Range (16VDC - 33VDC).
