If the area is prone to lightning strikes or voltage surges, a suppressor device
may be installed between the transmitter and the control unit.
If an additional loop-powered device or separately powered device is included
in the two-wire loop, the transmitter must receive a minimum voltage of
12 Vdc at 21 mA loop current. (See "Load Limitations" on page A-2).
