Take suitable anti-static precautions, such as wearing a grounded wrist
strap, when following ALL instructions. Remove all packaging from the
equipment and ensure that it has not been damaged in transit and all
items have been received - see checklist at left, before proceeding any
further. If no damage is evident, proceed using the instructions below. In
the unlikely event that damage has occurred or items are missing, DO
NOT PROCEED, contact your supplier and refer to Installation,
Commissioning & Configuration Manual.

Fitting the RS485 Interface Module PCB
With the back box installed in its chosen location, follow this procedure:
1Remove the cover, refer to Installation, Commissioning &
Configuration Manual, to expose the panel electronics.
Disconnect the battery interlink wire from the batteries and
isolate the mains supply.
2Carefully fit the two plastic PCB support pillars (A) in to the holes
(B) on the right-hand side of the PCB Assembly (C).
3Fit the RS485 Interface Module PCB (D).
i. Make sure the RS485 Interface Module PCB components are
facing the membrane and rest it 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 ensuring 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 it in guides of
the PCB Support pillars.
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.

4Connect RS485 Communications wiring at TB6 (as at below
left), ensuring correct polarity where applicable and fit the
cover.
If connecting the panel as the first or last station to 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.
5Apply the mains power supply and connect the battery interlink
wire. Configure the panel Installation, Commissioning &
Configuration Manual.
Removing the RS485 Interface Module PCB
If removing the RS485 Interface Module PCB follow the procedures
above in reverse order.
Ensure a backup of the current configuration has been made and
all power is isolated.
