Testing system wiring without alarm panel

Hello,

I have an existing wired system in my home. I have located the wiring panel/main board but I do not have any alarm panels to test connections. What is the best way for me to ensure that all of my sensors are properly wired? 

If I want to use my multimeter with the continuity setting, do what wires do I connect to red and black probes? Will that work?

Thanks in advance
