Secware Posted March 19, 2015 Posted March 19, 2015 I am using the 660 in conjunction with a scantronic 500r.The panel is 12v removed for alarm and the 660 is the opposite.The instalation guide refers to a dip switch to change the polarity. I cannot identify this on the board.Any ideas . Quote
Secware_Tech6 Posted March 19, 2015 Posted March 19, 2015 you can adjust the dip, are you connecting it to bell output? Quote
