Alarm battery replacement | Alarm goes off after power cut

Sorry that I'm looking to the side all video...
It's my first one and I was looking at the viewfinder and not into the lense.
If you have any questions I'll do my best to answer but if they're related to your specific unit it will be hard.

Not everyone is as lucky as you are 😂

Hi Sir. I have a regular home alarm which is powered by mains and has a sealed lead acid battery. As per my understanding, these batteries last only up to two hours during a power outage. Having been told about about LiFePO4 and it longer hours of service, is it (1) possible for me to do a straight swap and will the system recharge the LiFePO4 battery when power is restored. Thanks in advance.

How about making an alarm that sounds off when somebody shuts your power main with a 12 volt car battery for activation.

After a power cut I tried to reset my ADE Gen4 alarm. The 2 LED lights are both on, and the alarm is working when I enter my code, but I have a BLACK screen so I can't see the date/time etc. What could be the cause? Thanks

You don’t need to isolate the power to put in a battery 😂

what about the keypad not working
