Installation- No socket nearby

With no socket in the room the alarm panel is in, how do I power the konnected alarm panel? The current panel looks to accept AC power via a 3A unswitched fused spur (looking at alarm documentation and label on the panel states AC).

Is a transformer visible in the image below. If not, please advice on how to power this up. Thanks in advance

The board is for eurosec cp8l alarm. Power comes from mains switchboard to what looks like the the transformer but unsure if it is a transformer

Look like you can get 12V from the bottom left connector?

Thanks, I have ordered a pigtail to give that a try. Do you reckon it’s safe to leave the existing backup battery along with the panel.

Also, with the current eurosec alarm panel being left powered, could the tamper connections on the eurosec be left as is? If so, how would I be able to disable the panel speaker remotely, if triggered? Thanks

How to disarm the alarm remotely? This should be done via by assigning a key switch to one of the zones on the alarm.
