Hello. I am upgrading some AICO smoke alarms in a HMO where the existing alarms will expire soon. They are each wired from individual ceiling lights. On the top floor there are 4 alarms. I plan to go into the loft and from above, power the 4 top floor alarms from a single ceiling rose, instead of having each smoke alarm being powered from individual ceiling roses. I plan to use 6243Y (3 core + earth) cable that will allow me to interlink them and reduce the need for wireless signalling. So only one of the alarms on the top floor will require a wireless signalling module to communicate with the alarms downstairs.
My question is, "Should I wire them in series (one after the other) or can I have all 4 of them connecting to a common junction box."
I am asking, because it can be awkward to get 4+4 = 8 wires into the terminals of a single smoke alarm with your head pressed against the ceiling when wiring them in series. The junction box option could be easier for me.
I have included a diagram to help illustrate the 2 options that I am aware of.
Many thanks for reading this.
