Concerned about lack of color coding!

the following is just a general statement, without knowing the specific system that you have; Most window or door contacts are N/O or N/C (Normally Open or Normally Closed) magnetic switches and polarity makes no difference! Your best bet is to contact the manufacturer or distributor. They will give you specific information about the product! (No matter what) :yes::no::yawn:Don't Drink and Drive!!!

Polarity doesnt matter. Is it run with twist wire or quad? Either way polarity will not matter. Just put the same wires back on the new contact. I do alarms for a living.
