[Galaxy Classic 500 Strobe Wiring]

Hi All,

 

Finally getting round to starting the install of the house alarm in prep for each room coming online as and when they are decorated etc.

 

I have installed the main board and a smart psu with a local keypad for ease of programming etc. I already had a 12v strobe from my old installation but I cant figure out how to get it wired up to the strobes output.

 

It looks like there are three terminals on output 2 (on the rearmost board) but I only have two wires.

 

Can anyone help me out with this one please?
