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)

Nodes require a 4 core cable for interconnection,

and may be connected in a “daisy-chain” or “star”

configuration. The distance between each Node

must not exceed 100 metres. Power for detectors

is provided by the Aux +/- terminals. On

installations that utilise the Node 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.
