Review on URBEST HH52P Electromagnetic Power DYF08A by Alfonso Tipton

I have an intercom and wanted "that the nest doorbell also does the intercom doorbell. This relay worked great once I figured out which wire to plug in. After doing a lot of searching online and also checking other reviews I found that I had 2 individual wires between the "ends of the push pins" of the socket, and then connected the other wires to the relay at positions 13 and 14. I then connected another wire and connected it to both ends of the relay (closing the circuit if the relay is operated) with the other two ends of the wire screwed in. My intercom doorbell system FYI I use a 16v rated transformer and this 24v relay works with no problems - I have took a three current transformer and tried it on a 24v setup and apparently worked with that too.
