Fig. 3.4 Wiring F220-B6E Four-wire Power Supervision Bases

*The F220-B6E base has a normally-open alarm loop relay that activates when the unit is in alarm and a power supervision relay that activates when power is supplied. Separate power supervision devices, such as the D275, are unnecessary. Use only one F220-B6E per zone run. It must be the last base on the run.
