Description
Product Introduction & Engineering Value
The Autronica AKB-21-2 / 7255-015.0001 is an equipment-specific component intended for compatible Autronica fire detection infrastructure. The model designation and full part number should be kept together when sourcing a replacement.
For legacy installations, the physical label matters. Record the complete part number, PCB revision, terminal or connector arrangement, cabinet position, and host-system model before approving a replacement. A similar-looking Autronica module is not automatically an acceptable substitute.
Technical Specifications
- Manufacturer: Autronica
- Model: AKB-21-2

- Electrical Ratings: Confirm from applicable Autronica documentation
Technical caution: The supplied identification establishes the AKB-21-2 / 7255-015.0001 pairing, but it does not establish detailed voltage, current, I/O capacity, detector-loop characteristics, communication protocol, or terminal assignments. Those parameters should be verified from the equipment documentation.
Field Application & the “Trench” Experience
Imagine a maintenance shutdown on an older industrial fire detection installation. The technician removes a failed board marked AKB-21-2 and finds 7255-015.0001 printed elsewhere on the assembly. The spare-parts database contains only one of those identifiers.
That is exactly where procurement errors start.
Use the complete identification—Autronica AKB-21-2 / 7255-015.0001—and compare the replacement against the original board before installation. For a safety-related system, this is a much better approach than relying on dimensions or connector appearance.
Typical applications include:
- Marine fire detection system maintenance
- Industrial fire alarm control-panel servicing
- Legacy Autronica spare-parts inventory management

Transparency SOP: QA & Testing
For New Surplus or Refurbished AKB-21-2 / 7255-015.0001 stock:
Identification
- Confirm .
- Confirm
7255-015.0001. - Record revision and serial information.
- Compare all markings with the original unit.
Physical inspection
- Inspect connectors, terminals, PCB surfaces, components, mounting hardware, and enclosure condition.
- Check for corrosion, moisture exposure, contamination, overheating, or prior repair.
Electrical inspection
- Perform only tests appropriate to the confirmed module function.
- Do not apply uncontrolled power to unidentified fire-alarm electronics.
Functional testing
- Use an appropriate Autronica test environment when available.
- Document the exact test procedure and result.
Final verification
- Photograph the actual unit being supplied.
- Record condition and testing status.
The Veteran’s Tech Trap Guide
⚠️ Trap #1 — Using oe designation.
The full 7255-015.0001 number should remain on the purchase order and inventory record.
⚠️ Trap #2 — Assuming the “-2” suffix is cosmetic.
Do not assume or another variant is interchangeabh without manufacturer documentation.
⚠️ Trap #3 — Confusing visual inspection with functional testing.
For fire detection equipment, ask exactly what was tested. “Checked” is not a sufficient test description.
PRO TIP: Request an actual-stock photograph showing both and 7255-015.0001. Match the supplier’s photograph against the original assembly before issuing the purchase order.
Dynamic FAQ
What is Aua ?
is the model designation supplied for Autronica part 7255-015.0001, an electronic component associated with compatible Autronica fire detection equipment.
What is the Autronica part number?
The corresponding part number is 7255-015.0001. Both identifiers should be retained when sourcing or stocking the component.
n replaceB-21 module?
Do not assume that. The designation should be matched exactly unless Autronica documentation establishes interchangeability with another variant.
What information should I provide for an RFQ?
Provide Aua / 7255-015.0001, photographs of the complete label and PCB, the host fire detection system model, and any revision or serial information.
Is New Surplus acceptable?
New Surplus can be suitable for maintenance when the exact hardware is correctly identified, properly stored, and appropriately verified. It does not automatically establish system compatibility.
What warranty should I request?
Request the warranty duration, exact condition, test scope, and return policy in writing. For fire detection equipment, specifically ask whether the unit has undergone functional testing or only visual/electrical inspection.
