Cabling

The panel has high voltage barriers between the a.c. mains supply and the alarm

wiring terminals. It is essential that these barriers are maintained in the way the cables

enter the cabinet, are routed inside the cabinet, and are routed externally.

Additional holes must not be cut in the enclosure, rear entry points are provided for

cables. Alarm system cables must be neatly trimmed and not allowed to loop inside

the cabinet .

Cables external to the cabinet must be either firmly affixed to the fabric of the build-

ing using suitable clips or saddles, or mechanically protected in conduit or trunking. It

must not be possible to put strain on the wiring within the control cabinet by pulling

on cabling external to the cabinet.

It must not be possible to push a finger or similar size object or instrument into any

hole or cable entry point.

Mains Supply Connections

The connection to the a.c. mains supply must be made by a competent, qualified

person, for example NICEIC approved, in accordance with the current IEE and local

supply regulations.

Warning: A means of isolation from the mains supply must be provided

within two metres of the control panel. Where live and neutral

supplies can be identified, a fused spur with a 3A fuse, must

be fitted on the livecircuit. Where live and neutral circuits cannot

be reliably identified, 3A fuses must be fitted to both circuits.

Where a flexible cable is connected to the control having cores coloured brown and

blue it is important to connect the wires to the mains terminal block as follows:

• Blue (Neutral) – connect to terminal N

• Brown (Live) – connect to terminal L

Where a non-flexible cable is connected to the control having cores coloured red with

black sleeves, it is important to connect the wires according to the following code:

• Black (Neutral) – connect to terminal N

• Red (Live) – connect to terminal L

Note: No connections should be made to the Earth terminal (marked E) or on the

mains terminal block.

The insulation of each conductor must be prepared and connected such that no part of

the bare conductor is visible or protruding outside the terminal block. In the case of

standard conductors, all the strands must be twisted together and firmly clamped in the

mains terminal block.

The outer covering insulation must be clamped under the cable clamp. It is important

that this cable enters the control panel enclosure through the mains entry hole under

the mains terminal block, is not looped within the control panel enclosure and does not

run close to other system cables inside or external to the enclosure.
