Note: If a single cable is used to supply power to several elements, the distances given should be
divided by the number of elements connected to the cable.
If several wires of the same cross-sectional area and polarity are placed in parallel, the
distances given should be multiplied by the number of wires.

* This will free up the alarm relay when there are several alarm relays connected in series
(for example, different units on one pillar). If this option is not required, connect the alarm
