I'd like to change the location of a PIR and also do a service change on the battery.
Just wondered whether it was safe to remove all power ( battery and mains ) without losing it's current settings as I don't want to have to re program everything.
Thought it would be wise to avoid a short when rewiring the PIR ?
Also if all power is lost I assume there's no way to stop the external bells sounding until their batteries are dead ?
Any help would be appreciated.
