What Happens On My Lyric Controller When AC Power Goes Out?

In this video, Jarrett explains what happens to a Honeywell Lyric Controller when the AC power is lost. This can be caused by the electricity going out or by the AC transformer being unplugged from the wall outlet. Fortunately, the panel has a backup battery to keep it running whenever this happens.

AC power represents the primary power source for a Honeywell Lyric Controller. This is how the system should remain running the vast majority of the time. Using a backup battery is only recommended for the rare instances in which AC power is unavailable. In the event that AC power is lost, a user should work to restore it as soon as possible. This is because the system can only remain running on backup power for a limited duration of time. Once the battery power is also lost, the system will shut down entirely. To

Additionally, certain system features are made unavailable when AC power is lost. If a Lyric System is running on backup power, then all Z-Wave functionality will be lost. Incoming commands from Total Connect 2.0 and AlarmNet360 will not be received. Any outbound events that are sent by the system will not be logged in Total Connect 2.0. Any current firmware download sessions will be immediately stopped. The touchscreen will go dark after a few seconds of inactivity. Help videos and the video button will not work. Certain advanced system options will be unavailable. Keep in mind that these are just some of the issues that occur when AC power is lost.

Restoring AC power to a Honeywell Lyric System is very easy. If the transformer was unplugged, simply plugging it back in will restore AC power. If the electricity went out, the user should wait for it to come back or use a power generator. If the system was shut off entirely, restoring AC power will have it power back on automatically.
