Kidde VM-1 Technical Reference Manual

Appendix A: System calculations
178 P/N 3101890-EN • REV 006 • ISS 21JUN18
You will need to calculate the following values relating to your power supply and to the NAC circuit current. These
are:
• Minimum voltage
• Voltage drop
The minimum voltage is the lowest voltage measured at the NAC terminals when the power supply is under the
maximum load for that circuit (i.e. for the appliances that constitute the NAC).
The voltage drop is the difference between the minimum voltage and 16 V. This value is for use with the
worksheet only.
