    Is it a standard lighting Electrical cable that makes all interlinked mains alarm sound when triggered by one smoke alarm or is there another cable that does this?

    Hardwired interlinked smoke alarms are interconnected with 3-core and earth cable. Usually regular PVC sheathed mains rated cable. Nothing special.

    Once they all go off together I guess you can silence them all by pressing just the one button on one of them?

    On Aico you can silence them all, but ONLY when you press ALL of the ones that are being triggered by smoke.

    So when I burn the toast and set off the alarm in the lounge and in the hall I have to silence them both to stop all 10 off them arround the house from sounding.

    That may be something that is used in your foreign country, but not exactly an off the shelf item in the UK.
    There are other cables that the OP could use (why didn’t you mention 4-core FP200?) but I replied given he/she is asking about a UK domestic setting.

    RD415 is pink rather than red to differentiate it from FP200. FP is more for commercial fire alarm systems. RD415 is a truly excellent innovation, and the local RECI Inspector was very interested to see it in use.

    We don’t have RECI inspectors in this country. This diversion will confuse the OP who is in the UK. Better to continue this in the “outside UK” forum?
