Do they show negative or positive when triggered? I'm hoping negative because I ordered some to interface with my Scytek alarm. Let me know! Thanks!

Thank you all! I would have used a relay if it wasn't so!

Depending on the sensor, - multiplexed (timed pulses on dual zone sensors) technically.

Always check info with a digital multimeter.
I promise to be good.
Tell Darwin I sent you.

I've been sick lately, sorry I won't be on much.
