Cable Routing
When installing cables, the following should be
noted:
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.
Screened cable may prove necessary if
the Network or ID loop is run adjacent to
cables that produce R.F. or are switching
high current loads, e.g., mains, telephone,
computer etc.
Mains power supply cables to the system
must be connected to an un-switched
fused spur that cannot be accidentally
switched off. The mains cable 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.
Remote/LEC Network Wiring
The Remote Network connections are used for
connecting either remote keypads or LECs. Each
device has 5 connection terminals and therefore
a 6 core cable is required for interconnection. It is
recommended that the spare core is doubled up
with the [B] connection as this will help reduce
voltage drop on long cable runs.
Devices can be individually connected back to
the control panel (star connection) or looped
together (daisy-chain connection). Which ever
method of connection is used the distance to the
furthest device from the control panel must not
exceed 100 metres.
Power for detectors are provided by the [A] and [B]
terminals (see figure 2).
