I have a GE home security system. Last week there was a power surge due to a blown transformer in the neighborhood. A few hours afterward the systems siren sounded & would not turn off. So we disconnected it. The next day the key pads started beeping loudly. We are were able to turn them off by hitting the cancel button only to have them come back on within 5 minutes. The power comes and goes on the key pads during all of this. Any suggestions? Would unplugging and replugging in the seystems power transformer up in the attic be advisable?

Check that you are not using an app that is continuously accessing the internet and communicating with a server for some reason that is using the phones WiFi or mobile channel. This will drain battery life if incorrectly configured etc ( i.e selecting access to your location, services and other info )

Please remove the power and keep aside for few hours if you do not have instructions to reset the processor in the manual- please refer to troubleshooting processor.
If not the processor will reset by itselt if keep out of power, remove power plug and press the front panel to remove all voltage from the panel and it will reset if there are no issues on the power supply.

Check the outlet to ensure it :1- has power , 2- is not a switched outlet. Check your wire connections to ensure they are secure. If all of the above are good, the transformer may have shorted when disconnecting. Use a voltage meter on the transformer terminals and the AC scale, check the output of the transformer.

X10 is a signal format transmitted over the power lines, there is no special X10 wiring in the house as such. The siren and your outside lights are X10 receivers which are sent a signal from the X10 transformer connected to the alarm panel. The alarm panel sends the codes which are transmitted as X10 to the X10 external devices. Most houses now days have at least two 120 volt feeds coming into the main power panel, this provides the 240 volt required for electric stoves and dryers. Because of the two separate feeds split at the panel, the 60 cycles is usually out of phase with each other. To get X10 to work and stay in phase on each side of the panel you need to have wired a passive coupler across both 120 volt inputs. This coupler keeps both 120 inputs in phase with each other and provides a clear X10 transmit across the house wiring.

Possibly the power supply was damaged but could as simple as a blown fuse due to a possible "surge" when the power came back on!

Try this

1. Open the Control Panel cover.
2. Unplug the transformer and the battery.
3. Simultaneously press Cancel, Clock Set, and Minutes.
4. Restore power to the panel with either the battery
or the transformer while pressing these three buttons.
5. Plug in the transformer or connect the battery.

Read the battery voltage with the system on but with the ac power disconnected. I always suspect the battery from experience. Battery needs to be replaced every few years normally(but can vary).

power down the system by unplugging the transformer and the battery.  power it back up by battery first followed by the transformer.

you may have had a lighting strike to the phone line causing a surg to your unit. it may be fried. try completly powering down the system and powering it back up, then try to send a signal to your monitoring station. also you my have your monitorimg station try and connect to your system and check the programing it may have been scrambled.

I install these panels.  For the low battery message to clear you need to power the system down completely.  To do this you need to unplug the battery and also unplug the transformer plugged into an electrical outlet.  When you power the system back up, you need to first plug in the battery leads.  Then the transformer.
