MirXR2x_KIT possible power surge damage

We installed a MirXR2x_KIT and they worked well for about 4 months. The site we installed them at had a storm over the weekend and the power supply to one of them no has no power output. To check the relay it was connected to we used a 12V battery. It powered up the relay but it would not connect to the other relay. We killed power to both and then repowered but they still didn’t connect. We then took the relay that had the bad power supply in the same room with the other relay and it still wouldn’t connect. Do you think whatever got the power supply damaged the relay also? Do you have any suggestions?
