NOTES:
NETWORK. Master-slave (Network)
communication is by shielded
twisted pair cable, RS485
compatible such as Belden 9841.
Maximum overall system length of
1650ft Connect screen to C0.
NOTE: Diagram shows a master
and ONE slave configuration**.
Wire further slaves in parallel.
REMOTE SWITCH INPUTS should
be connected by 18 Awg cable.
Max length is 325ft.
Low voltage switching inputs to be
normally open (closed circuit to
enable).
Connect to B0 & B1 for remote ON
(ie BMS time control).
REMOTE SENSOR(s) may be
placed at a max distance of 325ft
from the control unit, using shielded
18 Awg cable.
Wiring should be kept separate
from mains wiring to minimize noise
pick up. Set within Engineers
functions for all remote sensors.
IMPORTANT:
Cable A is only required if the
24VAC supply to the panel
DOES NOT originate from the
secondary of an isolating
transformer.
