we are trying to confirm that the unit has failed. If you put a wire link between each set of the terminals to ensure its not external. Im thinking as the built in reed isnt working your fault is here or external.
Daft as it is this showed up in another search.
Must will be loads of keypads not operating correctly, who would of thought a non serviced bit of kit would not work perfectly after 20 or so years.
Seen this on ifsec site

do we think that cctv can be of any use in this? If so is it just for the next few months when its gonna be difficult to install?
No I didnt lol.
I assumed (maybe incorrectly) you had external devices connected to the contact transmitter. If so its those id link out with a bit of wire. Maybe a photo of the unit its decades since ive seen one
IIRC they are seperate it wouldnt surprise me if each one was 800 or 400mA But you will have additional 12v connections other than hold off for example if you want to balance the loads
