I have 2 radar sensors for my Omega Excalibur alarm. Prob is there is only one 4 pin attachment for 1 aux sensor. They sell a sensor expansion module where you can hook up to 3 sensors up. I just thought maybe I can fuse 2 sensors together and form a Y, going into the alarm. Know what I mean?

 

i have 4 sensors hooked up the the one MUX output of my alarm. make sure you isolate each trigger with an appropriate diode.

i confirmed it with the tech guys at autotoys that the 700mah that my alarm puts out is enough power for all 4 sensors. so far, i haven't had any problems.

 

dei's instructions tell you to daisy chain theirs.

 

Whats the diode for? Any particular direction the bands should be facing?

 

it's like a one-way water valve, it only allows the electricity to flow one way
