CHAPTER 2 Wiring Systems In this chapter we will investigate a selection of the many wiring systems employed in modern installations. Some of these systems are simple to understand and require little explanation. , present only minor problems of interpretation. It should be noted that diagrams for LV systems rarely indicate conductor colours, it is more likely that control circuit and ELV system diagrams will show these. 1 shows the colours/ alphanumeric references required by the IEE Wiring Regulations.
18 Fire alarm system. 19 RA2 Sounder RA Closed circuit. open (N/O) contacts RA1 close and normally closed (N/C) contacts RA2 open, the relay remaining energized via contacts RA1 when the reset button is released. The alarm sounder mute switch is then closed, and the whole system is now set up. An interruption of the supply to relay RA, by operation of any call point, will de-energize the relay, open RA1 and close RA2, thus actuating the alarm sounder. The system can only be cancelled and reset by use of the reset button.
Some difficulties may be experienced in wiring when the component parts of the system are produced by different manufacturers. In this case it is probably best to draw one’s own wiring diagram from the various details available. 28 Pump E E Internal connections of mid-position valve. EXTRA LOW-VOLTAGE LIGHTING These systems, incorrectly referred to as low-voltage lighting (low voltage is 50–1000 V AC), operate at 12 V AC. They employ tungsten 50 Wiring Systems and Fault Finding For Installation Electricians halogen dichroic lamps, which have a very high performance in comparison with 240 V halogen lamps.
