I've seen two cases (both, incidentally where the sub has opted for no
siren, inside or out) where the perp ripped the keypad off the wall.
In both cases they thought they had defeated the systems and took their
time - leaving the building right into the comforting arms of waiting
police.
Okay, both times the perps were teenagers (14 and 16) so they were
hardly the most astute criminals, but in my mind B&E guys are rarely the
sharpest tools in the shed.
I have a friend who's ADT "Lynx" clone was ripped off the wall during
the entry delay cycle by a group of thugs that wound up spending about
two hours ransacking the place afterwards. The "professional" installer
mounted the main control unit next to the back kitchen door and used a
two minute delay so that the family would have time to get from the
front door to the keypad. Even with a smaller delay, it wouldn't have
made a difference in this case (ADT uses an additional 45 second
programmed delay from the time you hear the siren to when the system
actually communicates the intrusion as a "false alarm prevention"
measure). When I first saw the install, I advised him to contact ADT
and "upgrade" the system, but the sales guy at ADT told him that I
didn't know what I was talkin' about. Damn I hate it when they prove me
right. With the exception of the poor choice for locating the main
control, they did do a pretty good job of protecting the family. All
the doors and windows were protected and they included smoke and carbon
monoxide detectors.
