ante Posted December 22, 2004 Report Share Posted December 22, 2004 Hi labso,Welcome to this forum.You have to arrange some kind of battery backup system. How much current does the system draw when triggered, including sirens and what else is connected to the system? Quote Link to comment Share on other sites More sharing options...
