Power Wiring: Use Table 10: Wiring Table for NACs on the previous page to see the wiring information for the
remote annunciator being used.
RS-485 Wiring: See the wiring information for the remote annunciator being used.
4-Wire Smoke Wiring: The maximum allowable current is 0.2 amperes. The maximum allowed voltage drop is 1
volt. Refer to Table 10: WIring for NACs on the previous page.
Shield for Analog Loop Wiring: Only twisted pair is recommended, but if shielded twisted pair is used, wire shield
at the start and the end of the loop to the terminals marked Shield at the loop adder board.
