My best guess is that there could be a very fine layer of corrosion on the contacts. Try cleaning them with a nylon scouring pad (e.g. Scotch Brite) and return the same battery to see if that stops the chirping.
Also, if you can, test the charge on the 9V cells.

If it's hard-wired then you would have alarm cable running to it which also supplied 12v and could consume 50mA. A purely battery powered device is going to have a reduced power consumption and very low standby current draw.
