Figure 6
b. Connect the 24 Volt DC power supply wires to pins 1 (-) and 4 (+) of the J1 or J2 connector
observing the correct polarity. Refer to Figure 2. Firmly tighten down the two slotted screws
with a small screwdriver taking care not to over-tighten the screws.
Pins 2 and 3 of the J1 and J2 connectors are the RS-485 interface used only for downloading the
FirePic from the Detector's non-volatile memory, or for viewing the Tri-Mode Plot.
recommended to wire pins 2 and 3 to a separate junction box and properly identify them for future
use. A color-coded, multi-connector, shielded, UL-rated cable with 18 to 24-gauge wire is
recommended for connecting to J1 or J2. The following color-coding is suggested as a guideline:
