turn off

Hello, I have a Scantronic 9651 alarm which is beeping and low battery sign showing. I had it replaced by an engineer 4 years ago but I never use the alarm and just want to deactivate the whole thing... is this possible Without an engineer call out?! Thank you.

Hi guys, as the title says...Who Actually Turns Off a Smart Metre....my daughter just switched energy suppliers and the new supplier does not use Smart Meters ..so we know it will/should be turned off....BUT who actually turns it off .....the Old Utility Company or my daughter ? Cheers anyone...
