Cabins are not pressurized to 5,000 feet equivalent -- it's closer to
8,000.  Also, pressurization doesn't just kick in and hold steady at
the desired altitude, so a device set to trigger at, say, 6,000 ft
might not trip until the aircraft reaches 13,000+ ft, with the cabin
altitude gradually increasing to that point.
