Is the inline motion sensor (BDL-VAC-MOTION4-PBK) 12 vdc or 12 vac? Where can I find detail specs for this device?
I didn't see anything in the pdf for this product that addresses your questions. If you need an answer fairly soon, you may want to contact customer service directly or post your question on the product's page. HTH
All of our low-voltage products are designed & optimized for use with 12VAC. 12VDC could in theory work as well, but we do not test for this & would not recommend for longevity, performance or warranty purposes.
