This includes the Doorbell, Phones and Panic Alarm.
The systems are all powered by a 12V transformer sitting under the tech box desk far end, stage right. The panic alarm and phones are almost two separate systems that meet in the tech box and use the same cabling to speak to the tech box and other parts of the building. The cabling system is based on bell wire (12 cores) though there is a small section in the servery that uses two small stretches of cat5 (8 cores) (this is because we couldn’t find any bell wire and currently the building has kilometres of cat5)

Please note that the cables are of the age that make them brittle buggers and liable to snap at any movement. This also means that they have faded and as such identifying the colours is a pain. When two colours are listed, i.e. White/Blue this denotes White wire with Blue stripes.
