Guest D Posted September 26, 2014 Report Share Posted September 26, 2014 Hi All I have purchased an EI156 as a replacement for a EI150 and it has two extra wires that are not shown in the wiring diagrams. The power block wiring is the same between the two units but there is an orange and purple wire which are not mentioned. Do these need to be wired in? Thanks Quote Link to comment Share on other sites More sharing options...
Safelincs Posted September 29, 2014 Report Share Posted September 29, 2014 It sounds as if you have been supplied with an Ei156TLR instead of an Ei156TLH. The two extra wires are for an older style of wiring to things like the old test/hush switch or old style call points. Presumably you don't have any of these? If this is the case, then the two extra wires can be ignored and the alarm can be wired as normal. Harry Quote Link to comment Share on other sites More sharing options...
