    We have a annex building which is at the bottom of the garden.

    I wanted to bolster the safety provision in here. It has a mains powered AICO smoke alarm but I am worried that if it wasn't occupied, we wouldn't know that a fire has started as we would be in the main house.

    I ahve installed interconnected smoke detectors in the past and was wondering how that would work in this scenario as the buildings are around 15 metres apart with the garden separating them. Which type of 3 core and earth would be required?

    Also, is there an option to have a speaker in the house that just amplifies the sound upon activation or does it have to be another AICO smoke detector in the house?

    Thanks in advance.

    Wireless interlink, connected to the ones in the house.

    How reliable is this over a distance of 15 metres and please excuse my ignorance but does this rely on the house Wi-Fi?

    Works up to 100m line of sight, and 30m indoors. Doesn't use wifi in any way, it's a direct radio signal from one device to another.

    Check the spec on them to ensure that the wireless link integrity is actively maintained (the remote should be sending an 'i'm here' signal every few minutes, the host should alert if one or more of these squirts is missed). I've got a very cheap wireless alarm system- it doesn't notice if detectors go AWOL.

    That particular item is battery powered.
    Total nonsense using it where mains power is available.

    For existing alarms it either a radio base https://www.tlc-direct.co.uk/Products/EI168RC.html
    or a module https://www.cef.co.uk/catalogue/products/4666115-smartlink-module
    depending on what type the existing alarms are.

    If you want new alarms as well, then it's the 3000 series with the module as above.
