Door Contact connection

[Stephen Coates]

I purchashed a magnetic door contact, which arrived without instructions.

It has six connections.

2x on a tiny reed switch

2x on a larger metal switch

and the other two at either end (seemingly not connected)

How do I connect it to an zone input.

Door and window contacts used in Intruder Alarm systems have two wires which are connected to Comfort. These are connections to the reed switch which is either open or closed.
Perhaps these other connections are for the EOL resistors, in which case they are connected to the other terminals. If there are no instructions, you will have to use a multimeter to measure the terminals to see which is connected to other terminals
Hope this helps
