4.3 Wiring the F220-B6R
The F220-B6R is the standard base for four-wire
configurations. The Alarm Loop Relay (terminals NO
and C) is a normally open relay rated 0.5 A use at
100 VDC. The relay closes on alarm.

4.4 Wiring the F220-B6C
The F220-B6C base has a normally open alarm loop
relay and auxiliary Form C (NC/C/NO) contacts.
The contacts are rated 0.5 A use at 125 VAC and 1.0 A
use at 30 VDC for resistive loads. Do not use with
inductive or capacitive loads.

4.5 Wiring the F220-B6E
The F220-B6E base has a normally open alarm loop
relay and an auxiliary set of normally open contacts.
The contacts are rated 0.5 A use at 125 VAC and 1.0 A
use at 30 VDC for resistive loads. Do not use with
inductive or capacitive loads.
The F220-B6E base also provides EOL power
supervision through a built in relay. 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.
The EOL Relay is rated 0.5 A use at 100 VDC for
resistive loads.
