Narrative:

I took off and after about 10 minutes I leveled off at FL240 for our final cursing altitude. Not to much longer after that we got a pressure system light. I looked at the cabin pressure and it was at 10;000 and it was climbing rapidly. The copilot called ATC and declared an emergency. I started an emergency decent and at the same time resetting the cabin pressure system. ATC cleared to descend to 12;000. I level off at 12;000 with the cabin pressure system reset. Everything was back to normal. I decided to continue going to destination. I called ATC and I asked for there telephone number and name. After landing I called ATC to make sure everything was ok; they agreed. There was no other airplane involved.
