Product Introduction
The AUTRONICA BSA-100 (7212-142.0007) is the main processor board inside the BS-100 DYFI fire alarm control panel, handling loop management, alarm logic, and system configuration for analogue addressable detector networks.. It’s chosen in legacy marine and industrial installations because it centralizes DIP-switch addressing, function-code strapping, and expansion control for BSD/BSB/BSJ/BSL modules in a single, serviceable PCB..
For teams maintaining BS-100 DYFI panels, this board is the direct replacement when the original motherboard fails or when expanding loop capacity and I/O.. We stock verified units with documented testing; condition is clearly stated per listing (New Surplus or Refurbished)..

Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| Panel won’t power up; no display, no LEDs | Mains/battery fuses (F1/F2) removed or blown; PSU fault | ❌ Low (external to BSA-100) | Measure 230 V AC at L1/L2 terminals; check F1/F2 per label; verify battery polarity at List 2 . | Replace fuses; verify mains and battery before swapping board. |
| “FAULT” LED on; display shows loop fault | Loop wiring open/short; wrong DIP reset number; loop speed mismatch | ✅ High (BSA-100 config) | Read fault text; verify S401/S501 reset numbers = addresses+1; check S201 loop count; confirm 1200/9600 baud strap settings . | Correct DIP/straps; isolate loop segments; test with known-good detector. |
| No communication to BU panels / repeaters | BSL-100 channel address or protocol (ASAP/ESPA) mis-set | ✅ High (via BSL-100, configured on BSA-101) | Inspect BSL-100 S1/S2 settings; confirm channel (1A/1B/2A/2B) and active/passive mode per table . | Reconfigure BSL-100 switches; verify cabling and termination. |
| Alarm outputs (AK-1..4) don’t activate | BSB-100 not addressed; S202 element 2–4 wrong; fused outputs blown | ✅ Medium (BSB-100 + BSA-101 config) | Check BSB-100 S1 address; verify S202 elements 2–4 match number of BSB modules; measure 24 V at AK terminals under load . | Set S202 correctly; replace 1 A fuses (F31–F34) if open . |
| Random resets / processor faults | Bad backplane contact; ESD damage; failing EPROM/RAM | ✅ High (BSA-100 hardware) | Reseat board; inspect for corrosion/heat; if available, check service menu for restart counts . | Replace BSA-100; keep ESD strap on during handling. |
❗ If stuck, send photos of the front display fault text, DIP-switch positions (S201/S202/S401/S501), and a list of installed modules (BSD/BSB/BSJ/BSL). We’ll review against the commissioning tables before you swap hardware.
Frequently Asked Questions (FAQ)
Q: Is the hot-swappable in a live BS-100 panel?
A: No. Treat it as a non–hot-swap CPU board. Power down, remove F1/F2, discharge caps, then swap. I’ve seen panels lock up when boards are yanked live—don’t risk the backplane.
Q: Will this work with my BS-100 DYFI panel running P5-BS100-3E20?
A: Yes. (7212-142.0007) is the standard main board for BS-100 DYFI panels including the 3E20 (UK) and other country variants. Confirm your program version on the front display or service menu before ordering.
Q: My panel has 8 loops. Do I need extra settings on the ?
A: Yes. You must set S201 to reflect the total loops in use (binary table in the commissioning doc) and ensure each BSD-100 has correct loop addresses (S402/S502) and reset numbers (S401/S501). Mismatch here causes “loop fault” even with good wiring.
Q: What’s the difference between New Surplus and Refurbished?
A: New Surplus = unused, often factory-sealed or from decommissioned stock. Refurbished = cleaned, visually inspected, and functionally tested on a BS-100 rig (power-up, loop handshake, alarm output test). We state condition explicitly per listing—no vague “excellent” claims.
Q: Can I use this to upgrade from 2 loops to 16 loops?
A: The supports up to 16 loops total, but you must add BSD-100 modules (7 more for 16 loops) and configure S201 plus each BSD’s DIPs. Also verify power budget: normal draw ~170 mA at 24 V DC (no detectors/outputs), ~370 mA in alarm—size batteries and 24 V rails accordingly.
Q: Do you provide test reports or videos?
A: For refurbished units, test photos/videos and a basic functional checklist (power-up, display, loop poll, alarm output test) are available on request. We don’t claim “100% failure-proof”—we report what passed under load.
Q: Why is pricing lower than factory-new?
A: BS-100 is a legacy platform; genuine new boards are scarce. Our stock is surplus or refurbished OEM hardware, priced to reflect availability while maintaining traceability and testing. If you need exact firmware/function-code matching for a specific country variant, tell us your panel’s program code (e.g., P5-BS100-3E20) and we’ll match it.
