Connecting the zone circuits and conventional sounder circuits
Incoming zone circuits and conventional sounder circuits (if used) should be connected to the relevant connector
block on the Main Control PCB as shown in figure 11 below.
For typical zone circuit and conventional sounder circuit wiring diagrams, please refer to pages 7 and 8.
Figure 11 : Zone circuit and conventional sounder circuit connections
Connecting the auxiliary inputs, auxiliary outputs and relay outputs
Incoming auxiliary inputs, auxiliary outputs and relay outputs cables should be connected to the relevant connector
block terminals on the Main Control PCB. If screened cables have been used, all screens should be adequately
insulated and connected between the nut and washers on the base earth distribution post (see below) using eyed
crimp connectors (as per the zone circuit and conventional sounder circuit examples shown in figure 11).
For a full description of the inputs and outputs available on the panel, including typical wiring diagrams, please
refer to pages 8 & 9.
Important notes regarding the earthing of screens
All screens should be adequately insulated and
connected between the nut and washers on the
base earth distribution post (see right) using suitable
eyed crimp connectors. Do not disturb the lower nut,
this must be secure to ensure earth continuity. The base earth
distribution post is provided for terminating earth screens or
drains and not as the main earthing point. The system designer
or installer must review the external earth bonding (if required)
with respect to the national wiring rules. That is, if the type of
installation requires protective earth bonding, then this must be
applied externally and in conjunction with the type of earthing
system employed on that particular site. This must always be
done with regard to the appropriate national wiring rules.
