PROA7 and PROA7PLUS: What Happens During AC Loss

Here Dylan from Alarm Grid covers how the PROA7 and PROA7PLUS panels behave in the event of an extended power loss. If AC power is lost for more than five (5) minutes, you'll notice that the touchscreen on the panel goes dark. At the same time, the WIFI and Cellular communicators, if installed, will also power down. This is done to conserve battery power. Touching the screen will bring it back on, and it will stay lit only while in use.

Since the communicator or communicators are powered down, this means that you won't be able to connect to the system for remote control through Total Connect 2.0. However, if the panel needs to report a signal to the monitoring station, the communicator(s) will power on long enough to do so, and then they will power back down until AC power is restored or until another signal must be sent.

In addition to the screen going dark, the panel will provide a single beep every 30 seconds, basically saying, "Look at me!" If you acknowledge the AC Loss, the beeping will stop. The panel has a feature called Quiet Time which is always enabled and spans from 10:00 PM to 8:00 AM. If the power loss occurs during this time, it will not beep. There are some other trouble sounds that are also suppressed during this time. If the condition continues beyond 8:00 AM, it will begin beeping at that time.

One very important note is that the panel will randomize the AC Loss report to the monitoring station and Total Connect 2.0 with an up to four (4) hour delay. If power is restored before this report is sent, then it is NEVER sent, nor will the Restore Report be sent. For this reason, it is important to be able to check the event log of the panel to verify if a power failure has occurred.

To check the event log, tap the menu icon at the bottom of the main screen, then scroll down to Events. Enter your Master Code (default is 1234) and then you can scroll through events from newest to oldest. Although the AC Loss Report is randomized, it will be logged to the panel's event log as soon as it is displayed on the panel's screen.

Once AC power is restored, the message will clear on its own without you having to enter a code to clear it. This is another reason it is important to be able to check the Event Log to verify whether a power failure has occurred. For example, say you're away from home, and you attempt to connect to your panel through Total Connect 2.0, but you can't. When you get home, everything looks normal on the system. However, unbeknownst to you, while you were away, there was a 1.5-hour power failure. The power was restored before the panel reported the AC Loss or sent you a notification via Total Connect 2.0. When the power was restored, the AC Loss message cleared from the display automatically. Unless you check the Event Log, you will not know that the reason you weren't able to connect to your system was because of a temporary power failure.
