I have a project that has a 24vdc door strike controlled by 2 locations. 1 is a standard push button and the other is a thumb print reader with dry contacts. Wiring and polarity all appear to be correct as well.
Every 4-6 uses, the strike will fail to open the door, and a little while later it starts working again.
We have replaced every component with no success. The wire tests free of shorts or ground faults.
It acts like a thermal that kicks out, and then automatically resets, but the voltage at the dc power supply maintains a steady 24.5 volts.
Any thoughts?
