Scottish Health Technical Memorandum 2035 Parts 1, 2 and 3: for mains signalling on the low-voltage installations associated with a single site



This series covers mains signalling is a means of transmitting information or control signals by superimposing them on the low-voltage (230 volts) mains power supply conductors. Except for the simplest applications, such as intercoms, mains signalling systems need to be carefully designed for use on the network on which they are to operate. The purpose of this guidance is to enhance the information available to the designer/purchaser of systems and equipment.
