I installed a new GDS3710 yesterday at a customer that already had one on the premises. I am using GDS Manager and pushed the card info via Central Mode. But when I enter a code on the keypad and press # or scan a key fob, the unit just immediately beeps three times. I can remotely unlock the door with GDS Manager so I’m pretty sure the wiring is correct.
But here’s the thing, the original unit started doing the same thing as soon as I powered up the new unit.
Confession time: I hooked up the new unit using the same power supply for the strike as the original unit. When I learned the old unit started doing the same thing I put the new unit on its own power supply. But both units are still doing the same thing. Have I destroyed both units?
