System Installation
Cable Routing
When installing cables, the following should be
noted:
¨
Screened cable may prove necessary if the
Network is run adjacent to cables that
produce R.F. or are switching high current
loads, e.g., mains, telephone, computer.
¨
Ensure that all Network and detection circuit
cables are kept clear of mains supply cables,
telephone cables, R.F. cables and cables
supplying bells or sounders.
¨
Mains power supply cables to the system
must be connected to an un-switched fused
spur that cannot be accidentally switched
off, and must enter the housing via its own
cable entry point.
¨
In larger installations it may prove necessary
to fit remote power supplies to overcome
excessive voltage drops in the cable runs. It is
recommended that the Menvier 519XB is
used in these instances as it can be fault
monitored by the control panel.

Node Network Wiring (TS900+ Only)
XNodes require a 4 core cable for
interconnection, and may be connected in a
“daisy-chain” or “star” configuration. The
distance between each XNode must not
exceed 100 metres. The Aux +/- terminals
provide power for detectors. On installations
that utilise the XNode outputs to drive sounders
and strobes it may be necessary to fit a remote
power supply (Figure 2) to prevent over loading
of the control panel power supply.
