Not sure what type of alarm you have at home. I did a quick google search and found this, not sure if it's for your specific model of alarm or not, from http://www.apsalarm.com/faq.asp:
Should the AC/LB light be on?
- FBII users: you should always have a steady lit light, this means electrical power and backup battery are present
- FBII users: blinking AC/LB light means battery is going low or loss of electricity for prolonged period, or battery has reached its life span
- FBII users: no AC/LB light means loss of electricity to power supply - check all breakers, make sure they’re all turned on and also check to make sure power supply has not been unplugged from outlet
In my past experience, my alarm started similar sort of beeping and it turned out that the battery is dead and not chargeable anymore, ended up having to buy one from Dick Smith to replace it.
Good luck |
