Hi, these two issues recently popped up on my work’s Simplex 4010 for the second time after resolving themselves a few months back. My boss contacted our fire alarm repair company, and after inspecting it, they told him that the best option would be to replace the 565-802 24pt I/O board with a new or refurbished one or replace the whole system. After looking around a little, it seems like these boards are out of stock everywhere and are obsolete anyway. Replacing the entire system would be a huge undertaking, and knowing I have micro-soldering and board repair experience, he asked me to look into the problem. If anyone could direct me to where the issue on the board may be and the steps I should take to remove it without causing any damage or setting off the alarm to inspect it further, it would be greatly appreciated. The board doesn’t appear to have any physical damage or shorts that I can see, but it is somewhat haphazardly placed in the box, so it wouldn’t be surprising if I just can’t see it from this angle. Unless someone strongly advises against it, I would love to see if I can refurbish it myself if the board is indeed the problem. I have attached a bunch of photos below that will hopefully be helpfull.
Card 9 is the card that is directly mounted to the metal backplane in IMG_4746 (on the left). That’s where you will want to focus your troubleshooting on.
LAMP TROUBLE indicates that Point 21 of the card is either burnt out (which, I’m guessing not since the lamp is obviously lit) or the card detects some other issue with the lamp on that point.
Missing Card simply means the card cannot communicate back to the host panel. Have you tried a panel restart (warm or cold) yet? I would also check to make sure that your connections (going from the panel to the card) for communications (N2) are good as well.
I would also not advise trying to repair the component yourself. Doing so would void the UL listing of the component and (technically) your system would be non-compliant, and, if that were to cause it to fail in an emergency, you could be held liable.
…Alternatively… you could swap card 10 (which appears to be working fine, albeit haphazardly placed) into the place of card 9, and re-address it. If you’re okay with losing a few lamps on the annunciator, you can then remove the bad card from programming and remove its wiring.
Noted, thanks for the advice. how would I go about preforming the warm and cold panel restarts? I’m going to test all of the connections right now
Press the Menu button, [Login/Logout] Enter → Enter (to login) → You will now enter the level 4 passcode using the arrow keys. The default password is 4000. You will receive a Service Mode trouble from logging in at this level, but this will be cleared after a panel restart.
After that, back out using Exit/Clear, and use the arrow keys to scroll down to Panel Restart - you can then choose between [Warm Start] or [Cold Start] - Cold Starting the panel will cause the time and date to be lost. It will need to be manually set after the panel reboots. I would see if a Warm Start fixes it first.
The panel will also ask you several times if you want to restart. Press enter to continue. Please note that the system will be completely inoperable while it restarts (usually will not take longer than 10-20 seconds).
