Lyric Smash Protection Explained

In this video, Jorge explains the Lyric Controller's Advanced Protection Logic (APL). This is the feature that allows the system to successfully report out an alarm event even if the panel is destroyed during a break-in. Advanced Protection Logic is highly important for ensuring constant protection.

Understanding Advanced Protection Logic actually isn't too difficult. When an entry/exit zone is activated while the system is armed, an entry delay period will go into effect. This entry delay period gives the user a chance to disarm their system without causing an alarm due to a faulted zone. So if a user opens their front door while their system is armed, and the entry delay period is 30 seconds, they will have 30 seconds to disarm their system. If they don't, an alarm will occur.

But it's possible that an intruder may destroy the system during this entry delay period and leave the Lyric Controller unable to send out any signals. That is where Advanced Protection Logic comes in. With APL, the panel will send a signal to Honeywell's AlarmNet servers as soon as the system's entry delay period goes into effect.

Once this initial signal is received, the servers will know to receive one of two possible follow-up responses. The first possible response is a system disarm within the entry delay period. The second possible response is an alarm event caused by the system not being disarmed in time.

However, if neither response is received, then the server uses the system's Advanced Protection Logic to recognize that something is wrong. In other words, if neither a system disarm or an alarm event is sent out, the server will know that the system was unable to send out a signal because it was destroyed. Once APL has kicked in, it will count as a burglary alarm. Any emergency dispatch will then be sent out as if it was a normal alarm event.
