I want to replace my optima panel 8EP396A?

to let you understand,to power down the bell box you either remove the mains power to the panel,and battery power,the sounder will go off and run down till the sab battery goes flat,or you go up your ladders and disconnect the sab battery ,so friend no need to be so high and mighty on things you have little knowlage off :-)
