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
minimise noise pick up. Set within Engineers functions any
for remote sensors.
(n.c.)
IMPORTANT:
Cable A is only required if the
24VAC supply to the panel DOES NOT originate
from the secondary of an isolating transformer.
