17. Connect the incoming mains cable to the
power supply, leaving the earth core 3cm
longer than the live & neutral cores. (This is
a safety feature, so that if the mains cable
gets pulled out of the power supply, the
safety earth will be the last core to be
disconnected). See Figure 12.
18. Use the supplied cable tie to fix the mains
cable to the enclosure via the plastic loop.
See Figure 12.
19. Insert the plastic cover-plate (supplied in the
spares bag) into the two holes in the top of
the terminal block of the power supply. This
is to prevent unintentional access to the live
mains cable connections during installation
and commissioning.
20. Connect all incoming cable screens or drain
wires to the Earth bar or Earth stud as fitted.
Ensure that the electrical continuity of any
cable screen is maintained through to the last
device on the circuit.
21. Ensure all 12 DIL switches on the panel are
OFF.
22. Connect the Zone EOL devices as follows:
I. Standard Panel Factory Default mode:
Connect a 10uF capacitor across each of the
zone terminals. Observe correct polarity.
II. Standard Panel EOL resistor mode:
Connect a suitable resistor (3K9 to 6K8)
across each of the zone terminals. Set DIL
switch RESISTOR EOL to the ON position.
III. Twin-Wire Panel:
Connect the twin-wire EOL (see Figure 5)
across each of the zone terminals, observing
correct polarity.
23. Connect a 10K resistor across the Fire Signal
terminals.
24. Connect a 10K resistor across the Remote
Input terminals.
25. Connect a 10K resistor across each of the
Alarm circuit terminals.
26. If repeaters are required, they should be
connected and commissioned after the panel
has been commissioned. See section 8.6.
5.1.2 Battery removal & Replacement
Please refer to the DUO-CEL logbook for details
