2.7.1 Fitting the RS485 Interface Module PCB
With the back box fitted to the wall, install the RS485
Interface Module PCB as described below (ensure
suitable
anti-static
precautions are taken):
1
Remove the cover (see
Section 2.5.1
) to expose the
panel electronics. Disconnect the battery interlink wire
from the batteries and isolate the mains supply.
2
Carefully fit the two plastic PCB support pillars (A) in
to the holes (B) on the right-hand side of the PCB
Assembly (C).
3
Fit the RS485 Interface Module PCB (D).
Fitting to PCB Assembly PN: 394-191-001, 002 or 003
i
Make sure the RS485 Interface Module PCB
components are facing the membrane and rest the
PCB in the PCB Support pillar guides.
ii Gently ease the RS485 PCB and PCB Support
pillars away from the membrane and carefully slide
the RS485 PCB down the pillars until the 10-way
socket (E) aligns with the connector, PL3 (F) on
the PCB Assembly. Ensure that the components
do NOT foul on the membrane.
iii Carefully return the PCB Support pillars to their
normal position and, with a firm and constant
pushing action, connect the PCB.

i Make sure the RS485 Interface Module PCB
components are facing away from the membrane
and rest the PCB in the PCB Support pillars guides.
ii Carefully slide the PCB along the pillars until the
10-way socket (E) aligns with the connector, PL3
(F) on the PCB Assembly.
iii With a firm and constant pushing action, connect
the RS485 PCB to the PCB Assembly.
4
Connect RS485 Communications wiring at TB6 (see
left), ensuring correct polarity where applicable, and
fit the cover.
If the panel is the first or last station on the RS485
Communications Link, connect a 150R Termination
resistor to the PCB Assembly on the left-hand side
or the right-hand side terminals of TB6 respectively.
5
Apply the mains power supply and connect the battery
interlink wire. Configure the panel, refer to Section 5.
Removing the RS485 Interface Module PCB
If removing the RS485 Interface Module PCB, follow the
procedures above in reverse order.
Ensure a back-up of the current configuration has been
made and all power is isolated.
