Connecting an Expander to the Bus
Both wired and radio expanders provide a
connector for the bus at the bottom of their PCBs
(item 4 on Figures 15 and 17 ) .
Figure 33 Wiring Expanders
Addressing Expanders
The control unit assigns addresses to all devices
connected to the bus cable. You must start this
process off from the Installer Menu, during the
initial power up. See page 29 for instructions.
Expander Loudspeakers
During normal operation loudspeakers on
expanders repeat setting and entry tones for the
partition that the expander is allocated to. During
an alarm the loudspeakers repeat alarm tones.
Each loudspeaker draws up to 280mA in
operation. if there is more than one expander
loudspeaker then the bus may not be able to
supply sufficient current during an alarm.
Note that you must enable entry exit tones from
the expander loudspeakers from Installer Menu.
Step 5. Connect Control Unit
to Mains
WARNING:
ENSURE THAT THE MAINS
SUPPLY IS DISCONNECTED AND ISOLATED
BEFORE MAKING ANY MAINS CONNECTIONS.
All mains electrical connections must be carried
out by a qualified electrician and must comply with
the current local regulations (e.g. IEE).
Mains Cabling
Note: To avoid mains interference, the mains
cable must enter the control unit through its own
cable entry hole (7 in Fig 2) and must not be
mixed with other cables.
Mains Connection
Figure 34 shows the mains connection. Connect
to a suitable supply using a double pole
disconnect (isolation) device in accordance with
EN60950-1.
Caution:
Do not apply power at this point.
Anchor the mains cable with a strain-relief tie.
There is a eye located near the mains cable entry
hole for this purpose (6 in Fig 2).

Step 6. Connect Wired Zones
The control unit and the wired expander
connectors can be used for either four-wire CCL
detectors, two-wire CCL detectors or two-wire
FSL detectors.
Four Wire Closed Circuit Connections
Figure 35 shows the wiring for four-wire CCL
zones on the control unit.
