On the subject of the system sensor 2400 smoke, you only use the plus and minus for the hookups since it’s a 2 wire detector, you don’t hook up to RA. Also what’s wrong with the 2903-9101 strobe plate? I’ve heard of other collectors having problems with the 3rd generation 9101’s but I have several 3rd generations that I’ve never had problems with.

  1. I will try to test your idea with the 2400 to see if it works. Thanks for the advice.

  2. The 2903-9101 was working fine for me until Friday the 29th (September). When I picked it up to test it, the little strobe tube on the back of the circuit board next to the potentiometer fell right off, without me even touching it! I’ve had this happen with another 3rd-gen 9101 in the past, where the strobe tube gets really loose either from age, or me lightly touching it, but it still works, and then for no reason one day, it falls right off!

It should be pretty easy to re-solder to the board. The nice thing about these strobe boards is that most of the parts are standard off the shelf components, and it’s fairly easy to troubleshoot if it stops working.

5

I suppose I could re-solder it to the board, but based on how far the tube snapped off from the connections, I don’t know if that’s possible. As for finding a replacement part, where do you think I can find it, and what would it be called?

Are you referring to the yellow transformer, or the small glass tube that triggers the strobe?

7

The little glass tube.

The only thing I can think of that looks similar both in size and internal structure is a neon indicator lamp, but I’m not sure of a proper name for that component. Since there are no schematics available for these strobe boards, I am trying to reverse engineer my strobe board to figure out the schematic. I believe I have a majority of it figured out, but I still need to find information on a few of the components. If that tube can’t be soldered back on, I’d try one of the aforementioned neon indicator lamps. You can’t make the strobe any worse off if you can’t resolder.
