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 12: Wiring Table for NACs on the previous page.
