Honeywell’s alarm systems offer a technology called APL. APL allows for the system to send a signal upon the triggering of a door sensor, which notifies the monitoring station that the door was opened. If no disarm signal is received, which would be the case if the panel was destroyed during the break-in, the central station will react to the situation as an alarm, notifying yourself and the authorities accordingly. This feature protects your home or business even if the system is destroyed the second an intruder gets their hands on it.
