Does any of you clever people know what this gadget (stuck onto the wall outside the front door) might be? I'm worried that curious fingers are going to push the buttons and set off an alarm that I don't have the code for and it will be such a bother to get it sorted!
(it's about 10 - 12 cm/ 3 - 4 inches high and has a hinged plain black cover, that you might recognise, with the curly initials on the logo)
