Notification Appliance Circuit 2 - Remove the 3.9K ohm, 1/2 watt, resistor from Terminals 10 ( - ) and 13
(+), and connect resistor to Terminals 11 and 12. Connect field wiring to terminals per Figure 3.
Class B, Style Y Wiring
Notification Appliance Circuit 1 - Remove the 3.9K ohm, 1/2 watt, resistor from Terminals 6 ( - ) and 9 (+),
then connect it in parallel within the last device on the circuit. Connect field wiring to these terminals per
Figure 4. Be sure to observe polarity, and check all wiring prior to connection.
Notification Appliance Circuit 2 - Follow the same procedure as above, except Terminal 10 is negative ( - ),
and Terminal 13 is positive (+).
