Installation Procedure

8.4
1. Unpack the Control panel. If the panel door is
locked locate the panel keys (usually fixed to
the top of the panel) and open the door.
2. Locate the small plastic bag containing the
installation spares as follows:
22 x End of Line Resistors (10k ohms –
(i)
colour code brown, black, orange, gold)
(ii) Remote controls switch resistors:
Sound alarms - 4k7 ohms (yellow, purple,
red, gold)
Silence alarms – 1k8 ohms (brown, grey,
red, gold)
Reset – 560 ohms (green, blue, brown,
gold)
(iii) Valve monitoring resistors:
Valve open – 2k2 ohms (red, red, red,
gold)
Valve closed – 680 ohms (blue, grey,
brown, gold)
(iv) 3 x End of Line Capacitors (22F)
(v) Spare 20mm mains fuse T5AH250V
(vi) Spare 20mm battery fuse F6.3A250V
(vii) 2 x cable ties
(viii) 2 x C1565 actuator suppression units
(ix) A set of battery leads (Red, Black and
Blue)
3. Disconnect the display ribbon cable from the
internal control board by pulling firmly but
gently on the ribbon cable connector.
4. Disconnect the Earth wire from the chassis at
the top left of the chassis.
5. Remove the control panel chassis (complete
with power supply & control board) from its
fixings by undoing the screws located on the
chassis. The bottom left & right screws need to
be removed completely, the top left & right
screws can just be slackened. The chassis can
then be pushed upwards and removed. Rest
the chassis in the bottom of the enclosure and
disconnect the internal mains cables from the
terminal block at the top-right of the enclosure.
6. Remove the chassis and place the complete
chassis unit safely to one side. Do not remove
the control board or the power supply unit
from the chassis.
7. Place the empty enclosure against the wall,
mark and fix using the single fixing hole in the
upper section of the enclosure. Level the
enclosure and complete the fixing operation
using the remaining two fixing holes in the
lower section of the enclosure. The fixing
holes are suitable for 5mm diameter screws
(imperial size 10). Use stainless steel or
plated screws.
8. Gland the installation wiring into the enclosure
using the cable entry knockouts provided at the
top of the enclosure.

Do not connect any field wiring at this time.
9. When all installation wiring is complete, check
all the wiring to ensure that it is free from short
circuits, open circuits, earth faults, crossed
connections etc.
10. Connect a 22uF end-of-line capacitor across
the terminals of the last device in each of the
three zone wiring runs.
11. Check that any Manual Call Points on the aux.
zone are fitted with an activation resistor (in the
range 100 Ohms to 680 Ohms).
12. Connect a 10k EOL resistor across the
terminals of the last device on the Manual
Release zone.
13. Connect a 10k EOL resistor across the
terminals of the last device in each of the alarm
wiring runs.
14. Connect a 10k EOL resistor across the
terminals of the last device in each of the
solenoid wiring runs. If you are using the
C1565 monitoring and suppression board
instead of the end of line resistor, then note
that only one board can be used on each
circuit.
15. Connect a 10k EOL resistor across the
terminals of the last device for any additional
monitored input or output circuits being used.
16. Place the chassis in the bottom of the
enclosure and Re-connect the internal mains
cables to the mains terminal block. Ensure that
the Earth lead to the Earth Bar is connected to
the Mains Terminal block.
17. Re-connect the Earth lead to the chassis and
refit the chassis on the four mounting screws.
Reconnect the display ribbon cable to the
motherboard.
18. Connect 230VAC mains to the mains terminal
block provided inside the enclosure, ensuring
that the mains supply is isolated at the source.
The mains cable must be secured inside the
enclosure using a Cable Tie (see Figure 6).
DO NOT TURN THE MAINS ON.
An appropriate
disconnect device shall be provided as part
of the building installation. This device must
have a minimum contact gap of 3mm.
The mains supply should be protected by a
5A fuse.
Use only mains cable compliant to BS6004,
BS6500, or equivalent, within the following
limits:
