(6) Power must be supplied from a listed UL864 power supply, UL listed panel, or power
supply.
(7) Connect ground wire to grounding stud and fasten with washer nut.
(8) Terminate the RS-485 wiring:
(i) Terminate grounding shield to the IIM stand-alone enclosure ground
(9) Connect the wiring from trouble relay to a trouble monitoring circuit.
(i) Install 5.6k ohm (0.5 W) resistors on the Auxiliary Alarm IN and Auxiliary Trouble In
terminals, if these inputs are not used. If used, terminate the wiring at the IIM and
install the resistors at the devices connected to the Auxiliary in puts, as shown in
Figure 4.6.
(10) If the IIM is installed in a Style 4 configuration (see Figure 4.7), the RS485 termination
load on the last termination board of the run should be connected. This is accomplished
by setting both sides of the M/TERM switch on the termination board to the “ON” position
(see Figure 4.2).
