I have an existing garden circuit that control 4 lights in series and want to install a PIR ( with built in light) to turn the 4 lights on as well as the built in PIR light. The existing Garden circuit Is supplied from CU/fuse box in the garage to a switch on the garden wall. The cable from the switch has 3 wires (black, blue and red plus a green/ yellow earth wire). The cable goes to a junction box also on the garden wall. Inside the junction box the 3 wires are connected to a connection block. The blue does not connect to anything and terminates in junction box. The output cable to the 4 lights in sequence has 3 wires; blue, brown and green/ yellow earth. These lighting wires are connected to the connection box as follows; input red to output brown, input black to output blue and input earth to Output earth. This works well with no issues.
We have a PIR light with built in light. The PIR has 3 wires in a block; red(live), blue (neutral) and earth. We would like to connect this PIR to existing circuit as described above so that when movement is detected the 4 existing Lights Come on as well as the built in PIR light.
The PIR install leaflet only shows standard wiring red, blue and earth in a 3 connection block, there is no mention of Line, neutral or Switched line. Also what type of cable, other than outside use, should be used to connect to existing circuit ie 2 core plus earth or 3 core plus earth and which corresponding wires should be connected to existing connection box. Many thanks for any replies or wiring diagrams in advance

You need a separate PIR, you yourself said
So how can you use something that is not there?Blues wrote:there is no mention of Line, neutral or Switched line.
Above are my opinions Below is my signature.
Would you hit a nail with a shoe because you don't have a hammer? of course not, then why work on anything electrical without a means of testing Click Here to buy a "tester" just because it works, does NOT mean it is safe.
If gloom had a voice, it would be me.
