I have never seen an intruder alarm with EOL either but they may be on the market....the best advice is always refer to the supplied installation document. I think there may be some confusion here. I agree with you steve they are usually found in fire Alarm systems
The eol would go on the last device. I suggest you refer to the installation instruction .many systems are different, some can be a set of dip switches or a resistor. What are you installing ?
