Thank you, I never thought I’d have much luck finding one! A Simplex technician I know sent it to me for free, along with the extra cards, and I should be getting a 4004 and a 4020 as well. I’m very passionate toward the history of STR. I also have a 4001 and a 4010 panel, both of which are in almost mint shape. I’m also well versed in electronics and troubleshooting/repairs and have experience with other fire alarm panels, both conventional and addressable. I’m 20 and plan to get into the fire alarm/low voltage field by next year.
Yes, that’s how the panel was when it arrived to me. I assume it’s in it’s original configuration. It was supposedly fully functional with that card order. I see, I heard that the meter module can only be used in J2. Interesting. What makes me wonder a little bit is why some of the jumper holes have solder, like they had jumpers at one time. That’s what speculated me that I was missing jumpers, which is why the panel wasn’t working. But it’s possible that the panel was once set up with a different card configuration in the past as well. As it sits right now, when I apply power, the green power LED on the main board comes on. Nothing else happens. All of the cards are seated in place. Interestingly, if I swap the main control card from the one that came in the panel to the extra one, the same behavior persists although the system trouble LED on the control card is lit. That light is not lit on the original control card. I’m getting around 13 volts AC on the secondary of the power transformer. I’m getting around 30 volts DC on terminals 1 to 5 and 1 to 6 on TB4 on the top left, so the voltages seem to be there.
Thank you, help with that would be appreciated once I get the march time card. I ordered one tonight. From what I remember, each card gets a certain number of terminals on TB1 and TB2, both for the zones and the signal circuit outputs. Do you know if it’s possible for me once I get the panel going, to swap out say one of these single zone cards with a double zone card, or the single signal circuit with the dual signal circuit card, without needing to add jumpers? I’ve been trying to find detailed wiring information online and I can’t come up with too much for how the jumpers are used relative to what cards are used. Eventually, I will ideally like to add the double signal circuit card, possibly a few dual zone cards, and the 90BPM march time card.
I bet it’s bad too. Same thing happens on antique radios when the filter capacitors dry up, you get hum in the audio due to lack of filtering after the rectifier. Sprague made quality capacitors, but I will definitely change it down the road, and just for kicks I will connect it to my capacitance bridge after it’s out of circuit, which can check paper and electrolytic capacitors for DC leakage current as well as capacitance value. Handy when working on old gear.
Thank you again, I’m really appreciative I have been able to come to own such a beautiful panel, both in condition and historical significance, and preserve it from being lost to the scrap pile as so many of these have been. I plan to hopefully mount this one on the wall, with a few devices connected to it for a demonstration system, like I do with my other panels.
Here’s more detailed photos of the motherboard and the jumpers if you wanted to look it over, and the main control card as well.
