    Removing a PIR sensor from an ADE optima compact installation.

    Could someone give me a rundown of how I would go about disconnecting two PIR’s from an existing installation? I’m knocking down a rotten wooden frame conservatory and a shed which have sensors in and will need to permanently remove the PIRs from the system. Could anyone help me out? Thanks
