How can I tell if my alarm uses end of line EOL resistors?

Comments Off on How can I tell if my alarm uses end of line EOL resistors?

I bought new construction in 2018 and paid extra for prewired alarm sensors at the windows and doors plus a Interlogix NetworX NX-8E panel. I am going to replace the panel, but I am unsure about the use of EOL resistors. From what I see wired at the panel, I don’t see any resistors there. I’ve never investigated the actual sensors’ wiring because they’re already nice and clean. Is there an easy way to detect if they are installed correctly at the sensor without physically taking them apart? I assume a voltmeter etc and watched some videos about EOL but all this stuff is new to me so a bit lost. Thanks for your help.
