Hey guys Can You HELP ME !!! I"m making a security alarm for my house and I need some help with setting up a few things First I can't find a circuit diagram,that enables me to have a battery charging when the AC power is on and and then switch over to the battery when the power fails. Secondly I need to find a cost effective way in changing a N/C circiut to N/O on my PIR sensor as this would reduce the amount of circuits in my plan Thirdly I can't find an effective way to provide power to all my sensors and run the circuit as well The PIR sensor is 9-15v @ 12 mA the relay that triggers the allarms is : 125mA @28 volts max (i'll only be running 9-15 volts) if you could please send me any info or links that would help please e-mail me @ samfred16@xtra.co.nz If you have any circuit diagrams please e-mail them in either: .jpg or as an egale pcb design scematic .::sam::.
