AUTRONICA KM-2 Marine Alarm Monitoring System

Description

Key Technical Specifications

Historical industry documentation describes KM-2 as a newer version of Autronica’s KM-1 alarm and monitoring system, with two points per channel and digital reading as standard. It also identifies printer and mimic outputs.

Actual KM-2 installations can contain different modules and configurations. Documented examples include KMB-201/F, KME-200/T, KMR-200/600C, KMC-220, KMC-210, KMA-200/FBR, and other KM-2 components.

Product Introduction

The AUTRONICA KM-2 is an integrated marine alarm and monitoring system designed to collect operating-condition and alarm information from shipboard equipment. It monitors parameters such as temperature, pressure, and on/off alarm states and presents alarm information to the crew. Historical documentation identifies configurations ranging from 12 to 120 monitoring points.

KM-2 remains relevant mainly as a legacy marine automation platform. A documented ferry installation used KM-2 as the engine control room alarm system, collecting information from equipment and presenting abnormal conditions through visual and audible indicators.

Installation & Configuration Guide

Stage 1: Pre-Installation Preparation — 15–20 Minutes

⚠️ Safety First: KM-2 is marine alarm and monitoring equipment. Before servicing it, coordinate with the vessel’s engineering/operations team and place affected alarm functions into the approved maintenance condition.

Tools Required:

• ESD wrist strap
• Digital multimeter
• Insulated screwdrivers
• Wire labels
• Smartphone/camera
• Current KM-2 wiring documentation

Preparation Steps:

1. Record the complete KM-2 system identification.
2. Photograph the complete cabinet/panel before disturbing any wiring.
3. Record the installed module designations and part numbers.
4. Identify the number of monitoring points in the particular installation.
5. Record the connected sensors and alarm channels.
6. Photograph terminal blocks and cable routing.
7. Confirm which alarms and shutdown functions are affected by the planned maintenance.
8. Notify the responsible watchkeeping personnel before isolating equipment.

Stage 2: Removing the Existing Module — 5–15 Minutes

1. Place the affected alarm system in its approved maintenance state.
2. Isolate power to the relevant KM-2 assembly according to the applicable service documentation.
3. Verify the supply has been removed before handling internal wiring.
4. Label every connection before removal.
5. Disconnect wiring carefully.
6. Release the module’s mechanical retaining hardware.
7. Remove the module without stressing the backplane or terminal connections.
8. Inspect the connectors and wiring for corrosion, loose terminals, or heat damage.
9. Retain the original module until the replacement has completed testing.

Stage 3: Installing the Replacement Module — 5–15 Minutes

1. Verify the exact module designation before installation.
2. Check the replacement for mechanical damage.
3. Compare terminal and connector positions against the original.
4. Install the replacement in the correct position.
5. Secure the mounting hardware.
6. Reconnect the wiring according to the original photographs and approved drawings.
7. Verify sensor polarity and terminal identification where applicable.
8. Check all terminal connections.
9. Confirm that no wiring has been trapped or damaged.
10. Complete a visual inspection before energizing the system.

Stage 4: Power-On & Functional Testing — 15–30 Minutes

1. Check supply wiring before restoring power.
2. Restore KM-2 power according to the vessel’s approved maintenance procedure.
3. Observe the system during startup.
4. Confirm normal digital indications where fitted.
5. Check for alarm or fault indications.
6. Test representative temperature and pressure inputs.
7. Test applicable on/off alarm channels.
8. Verify alarm indication at the operator panel.
9. Verify alarm printer and mimic outputs where installed.
10. Confirm that affected alarm channels return to their normal state.
11. Record the test results in the vessel’s maintenance documentation.

⚠️ Important: KM-2 installations are application-specific. A replacement module should not be commissioned solely because its LEDs or display appear normal. Verify the actual alarm channels and connected sensors.

Frequently Asked Questions (FAQ)

What is the AUTRONICA KM-2?

The KM-2 is an integrated marine alarm and monitoring system from AUTRONICA. It was designed for shipboard monitoring of temperatures, pressures, and on/off alarm conditions. Historical documentation describes digital reading as standard and configurations from 12 to 120 points.

Where is the KM-2 typically used?

It is primarily associated with marine and shipboard automation, particularly engine control rooms and machinery monitoring. A documented ferry installation used KM-2 to collect abnormal-condition information and provide visual and audible alarm indications to the crew.

How many monitoring points can a KM-2 system handle?

Historical product information states that KM-2 panel configurations were available from 12 to 120 points. The actual capacity depends on the installed panel configuration.

Does KM-2 monitor temperature and pressure?

Yes. Historical documentation identifies temperature, pressure, and on/off alarm monitoring as core KM-2 applications. Actual sensor types and alarm limits depend on the vessel-specific configuration.

Is KM-2 obsolete?

It should be treated as a legacy marine automation platform for procurement purposes. Current secondary-market inventory includes complete KM-2 systems and individual modules, indicating that replacement hardware can still be found.

Can I replace a KM-2 module with any other KM-2 module?

No. KM-2 systems contain different module types. Documented examples include KMB-201/F, KME-200/T, KMR-200/600C, KMC-210, KMC-220, and KMA-200/FBR, each serving different functions.

Match the exact module designation and part number, not simply the KM-2 system name.

Can KM-2 be upgraded instead of replaced?

Possibly, depending on the vessel and required functionality. One documented KM-2 installation was expanded with an external alarm-event recording system rather than replacing the complete alarm system. The added system collected KM-2 signals and stored alarm history on an industrial computer and memory cards.
