Thanks, Sparks. This sounds more like it. There are a couple of
problems here. Firstly there isn't a keypad on this Control Panel but
I'm sure that I could still find the lettered terminals. The second
problem is that if the rechargeable battery in the SAB remains charged
then if the wiring is disturbed or disconnected as could happen with
feet when one is trying to crawl around in a tight loft then the SAB
would still activate if they became disconnected. Ideally I need to
deactivate it, remove any possibility of recharging and allow the SAB
batteries to leak their charge away by decay.
