Hello,
I have a scantronic 500r.+ system installed in 2002 which has been regularly serviced and works as installed. I now have a low battery light for one of the PIRs but the installer & servicer seems to have gone out of business as his phone contact is no longer recognised. Please could you say how to change the battery on the PIR as I do not know whether it has a tamper proof feature or not, hence, if I interfere with the PIR will it set off the alarm?
Thanks for your help, Roger
