First, check the panel's connection to AC power.

If the panel is plugged in and the rest of the house has power, there may be a problem with the outlet itself where the panel is connected.
 

If there's no electricity to the entire house:

Alert your local power company to the outage.

Don't assume that someone else in the neighborhood has already called!

A notification like one of these appears when your security panel loses AC power. At this time, the panel switches to its internal batteries.

NOTE THAT BATTERY BACKUP LIFE VARIES WITH EACH SYSTEM AND THE CONDITION OF ITS BATTERIES.

Important Notes:
  • Widespread power loss in your neighborhood may affect the cellular network that is your system's primary means of communication with your Central Station.
  • Backup batteries will keep your system operational for local protection (door/window sensors, Fire/CO sensors, motion sensors, siren/sounder in your panel). However, loss of AC power will very likely disrupt your system's connection to the internet. This connection is your system's backup link to the Central Station.
  • Battery backup life will vary with each system and the condition of its batteries.
  • Following the resumption of AC power, please pay attention to any Low Battery notifications from your system's control panel. Prolonged backup operation can drain your battery, and your system may not be ready for another AC power loss if it occurs soon afterward.
