<strong>Remote</strong> <strong>Line</strong> <strong>Controller</strong> (<strong>RLC</strong>)<br />
Product Manual<br />
Workmanship<br />
All wiring should be identified. The use of consistent cable types and colours for each element<br />
of the system will greatly ease system maintenance and future expansion.<br />
It is of vital importance to accurately label the installation and to provide detailed ‘as-installed’<br />
wiring drawings. Future maintenance and expansion of the system will depend on this<br />
information.<br />
Enclosure<br />
One <strong>RLC</strong> can be mounted vertically in the standard wall mounting enclosure with an IDC and<br />
power supply, or with a modem and power supply. Alternatively, a custom designed low-profile<br />
desk mounting enclosure is available.<br />
The enclosure should be installed in a secure area to prevent <strong>com</strong>promise of the system. The<br />
wall-mounting box may also be mounted horizontally if required. In all situations, sufficient<br />
space should be allowed to permit engineers to work inside the enclosures for future<br />
maintenance.<br />
The <strong>RLC</strong> should be installed in a clean dry area. It will work satisfactorily between a<br />
temperature of 0 degrees and 50 degrees centigrade with a relative humidity between 5% and<br />
85% and no condensation. The air should be <strong>com</strong>pletely free of corrosive gases<br />
Avoid strong magnetic fields generated by transformers and motors etc. Do not install the<br />
enclosures near to hazardous voltages or where they will be exposed to strong radio frequency<br />
signals.<br />
Power Supply<br />
If the <strong>RLC</strong> is fitted in a wall-mounting box then a standard 1 Amp power supply can be used.<br />
This is fitted in the same manner as for an IDC/IPC. Alternatively, if the <strong>RLC</strong> is mounted in the<br />
desktop enclosure then a separate plug-top power supply is available.<br />
It is re<strong>com</strong>mended that a standby battery be used. This is fitted in the wall mounting enclosure<br />
and is connected in the same way as for an IDC or IPC.<br />
Communications<br />
RS-422A <strong>com</strong>ms connections should be made with two individually shielded, twisted pairs (i.e.<br />
4 wires). All cable should be 22awg or larger, preferably stranded since it is less prone to<br />
damage during installation. Belden #8723 or it’s equivalent is re<strong>com</strong>mended.<br />
