Extending a single out put for multiple functions?

I have an Ungo G1100 it has one aux. output and its currently used to roll down back glass on vehicle. I seen on DEI website there is an output channel expander. I was wondering if i could add this to my alarm so i can have remote start and window roll down?

1 spare Channel +1 450T = 6 new channels! Add up to six auxiliary channels to any DEI security system, to control additional security or convenience features. Compatible with standard or high frequency systems.

I haven't used that particular unit, but it appears that it will work with any remote system with an auxiliary channel, and will likely work with your alarm, but you can contact them here to be sure: http://www.directed.com/contact/default.asp
