The touchscreen runs on A/C power and must be plugged into a wall outlet at all times. The touchscreen has an emergency back-up battery to ensure that your security system continues to communicate alarms during power outages. When A/C power is lost, the touchscreen places itself in Low Power mode. During Low Power Mode, your system loses remote control functionality and only broadcasts major system events such as alarms.
When the touchscreen enters Low Power Mode, the following occurs:
- The touchscreen LEDs turn off.
- The touchscreen stops communicating over broadband with the central monitoring station and the system servers (if the premise has lost power the router will be down as well).
- The touchscreen stops sending heartbeat signals to the system servers over cellular.
- The touchscreen reports an AC Power Loss trouble in the Trouble Header.
- The touchscreen tries to send an AC Power Loss message to the system servers over cellular if con-nectivity is available. If the system servers receive the message, the trouble will be displayed on the remote user interfaces.
NOTE: The remote user interfaces eventually might report a loss of broadband and cellular connectivity if the AC Power Loss message was not received. In this case, they will not report an AC Power Loss trouble.
- Fifteen seconds after the attempt to send the message, the screen of the touchscreen is dimmed.
While in Low Power Mode:
- When the screen is tapped, the touchscreen “wakes up” temporarily to display the Home screen, but you cannot use any touchscreen apps that communicate with remote sources. For example, you are not able to use the News app or Sports app.
- The touchscreen continues to communicate with the sensors and monitoring for other events.
- Most events are not sent to the system servers or the central monitoring station, although you can view them in the History on the touchscreen only. The exceptions are the following:
- Alarms
- Arming the system
- Disarming the system
- When the back-up battery power drops below the required operational levels, the following occurs:
- The screen does not wake up when it is tapped.
- There is no broadband or cellular connectivity.
- Generally, rules are disabled
- Just before the back-up battery goes completely dead, the touchscreen attempts to send a “Loss of Power” message to the system servers over cellular.
