Dude, it looks to me like you got a bad module.. It seems that all three test bad: 1. The transformer has an open secondary 2. The low-voltage protection module has an open cap 3. The alarm system simply beeps when I plug in 12VDC I plugged the 13.5V battery, without the ELK TRG1640 ac charger and without the D135A low-voltage-protection board, into the Radionics D2212B alarm system board. The alarm beeped continuously, without any other indication of working, and the current I measured was 98 ma continuous: http://farm8.staticflickr.com/7370/1...4f8a7d31_o.gif Can all that really happen simply by shutting off the 200Amp main breaker without also turning off the automatic power generator? |
