Hi, there. i installed an EDM Solution 862 system in 2002. The codepad has recently gone dead. No sound, no light, no response to any of the buttons. The rest of the system seems to be okay - sensors are flashing; when I removed one of the fuses the siren went off. I opened up the panel and checked out the codepad fuse but it seems fine. I opened up the back of the codepad but can't see any fuse. Is it possible that the codepad just died and how do I check? Can I get a replacement? I don't think this company (Electronics Design and Manufacturing, Huntingwood, NSW) exists anymore. I read somewhere it was taken over by Bosch. Would the new codepads works with the old system?

Thanks in advance to anyone who has knowledge of this system.
