Form C Relay to Elk Input

[stew]

I purchased one of the Sure Action Driveway sensors. The output is a Form "C" relay at 24VAC. Any tips on how to tie that to an elk input?

Thanks!

A form C relay is a SPDT (single pole double throw). This type of relay breaks the connection with one throw before making contact with the other (break-before-make). You can use either set of contacts depending on whether you want a normally closed or normally open contact. The 24VAC is the coil voltage.
