rhymerx 0 Posted February 15, 2016 I have similar system but with 12VDC Door Strike that connects to LK- (GND) and LK+ (COM) port on the door station. That system works fine and doesn't require power supply for operation. Second system I have the same Door Station but have two 24VDC Door Strikes, but maximum rating is 12VDC coming out from the Door Station. Is it possible to introduce 24VDC Power Supply or even Relay to the locks and if so can someone help me with the wiring because I am a little bit rusty with diagrams. I believe that Door Strikes doesn't have polarity. Below I've included some simple schematic of my problem. And the second one is from my existing system.

ssmith10pn 0 Posted February 18, 2016 Connect your 12v door station to the + and - of a RB5 relay Connect one leg of your 24v strike to your 24v power supply. Connect the other leg of your strike to the NO of the RB5 relay. Connect the second leg of your 24v power supply to the common on the Rb5 relay. http://www.amazon.com/Altronix-RB5-Relay-Module-Operation/dp/B001MRXYLC Share this post Link to post Share on other sites
