- Page 9 Tools and Equipment A magnetic field strength meter (e.g. Ampetronic FSM) or a loop receiver (e.g. Ampetronic ILR3 or ILR3+) is vital to check that the loop system is providing the desired level of performance. As well as tools for securing the unit to the wall, a large flat bladed screwdriver and hammer are required to remove the knock-outs.
- Page 10 Any knock-outs left open must be blanked off with a suitable plug. Cable glands and conduit fittings are available at most electrical suppliers. The CLS1 is classed as permanently connected apparatus and as such shall be installed in accordance with relevant building and wiring regulations.
