All About Crash & Smash and APLPosted By Michael Goris
Hi DIYers! We have many customers who wonder what happens if their security system is destroyed when an intruder breaks into their home. Fortunately, alarm manufacturers considered this possibility. They put protective measures in place to deal with this issue. Enter Crash & Smash and APL.
Crash and Smash (C&S) for Alarm.com and Advanced Protection Logic (APL) for Total Connect 2.0 are both features designed to provide an added layer of protection in case an alarm panel and/or its communicator are destroyed during a home invasion. These features help ensure that the police are still dispatched and that the end user receives the help they need. An intruder might think they're okay because they have destroyed the panel, but the system is smart enough to overcome this issue.
Just last week, we made a post covering Entry and Exit Delays. Well it turns out that the Entry Delay period plays a big part in C&S and APL. As we discussed last week, if an Entry/Exit Zone is faulted while the system is Armed, an Entry Delay countdown begins. This period gives the end user a chance to Disarm their system before an alarm occurs. But what if the panel gets destroyed during this countdown? After all, the panel won't be able to send out an alarm signal. But this is where Crash and Smash and APL take priority. How they do this is actually quite smart.
Whenever a system goes into Entry Delay, it immediately sends out a signal to the Alarm.com Servers (ADC) or the AlarmNet Servers (TC2). This signal just lets the server know that the system is now in an Entry Delay period. The servers are smart enough to know that since the system is now in an Entry Delay period, a Disarm or an Alarm must follow. If neither event follows, then logically the panel must have been destroyed. The server will then know to send a signal to the central station to let a trained dispatcher know that the panel has been destroyed and dispatch is needed right away.
Please note that the Alarm.com Servers and the AlarmNet Servers do not send signals to the central station as soon as the usual Entry Delay period expires. These servers also account for delays in sending signals. A little more than a minute of additional time is added beyond the normal Entry Delay period before a C&S or APL signal is sent to the central station. This is done to prevent false alarms.
Advanced Protection Logic and Crash & Smash also work during alarms that do not follow Entry Delay periods. If the system has Alarm Report Delay enabled and an intrusion alarm occurs, then the system will not actually alert the central station the very instant that the alarm occurs. The system will actually enter into a short Alarm Report Delay period that is usually less than a minute in length. This delay period gives the user a chance to Disarm the system and cancel the alarm to stop the signal from being sent out. If an intruder destroys the system during this Alarm Report Delay period, APL or C&S will ensure that emergency dispatch is still sent out. Alarm Grid encourages users to disable Alarm Report Delay on their panel if possible.
It's also worth mentioning that the Alarm.com Servers and the AlarmNet Servers send all C&S and APL signals directly to the central station. The end user does not receive an alert from Alarm.com or Total Connect 2.0 when these signals are sent out. In other words, C&S and APL do not work with self-monitored customers. You need a central station monitoring plan to use these features. Also, C&S and APL do not work with phone line monitoring. You need an IP communicator or a cellular communicator. UPDATE: Alarm.com can now alert a user directly via a Push Notification on their phone when a C&S event occurs.
