Well it could be a few things.
How old is the battery, more than 5 years, if yes, change it.
if the battery aint that old, it might just need time to charge.
If you've let the battery fully discharge, it may be damaged, and will need replacing
Could also be the charging circuit fuse has blown.
you will need a meter to check the above tbh.
hi changed battery but alarm going off all the time.when u say connect mains first what does this mean do i turn off electric mains then put battery in then close panel and then enter code on panel or keypad hope u can help as instead of f4 on keypad now have no 8.i did put battery in and alarm went of all time and when i typed code in wouldnt go off does it matter whether i connect negative or positive first many thanks
Yes thats the power-up procedure for a down-powered system.
If the system is disconnected then follow the instructions above, it dont matter what way you connect the battery, but, make sure the polarity is correct, red to red, black to black.
close the panel lid and enter your code to silence the alarm.
Reset with your code if required.
I not sure about that event code tbh, you sure its 8.i, could be a zone event but not 100% sure, would have to check.
Do you have the engineer code for the system, if not try the 1111# this will let you open the panel lid if the system was already powered.
Remember to just take your time, think about what your doing and dont rush just because the bells are going.
