Autronica KR-13A is identified in current listings as a dead man alarm panel for marine applications. The E-1235 listing identifies a K5 dead man alarm timer and K4 prewarning timer with a 0–3 minute range. Variant markings matter: separate listings reference KR-13A/Y2H and KR-13A/Y6H configurations.
Product Introduction
The Autronica KR-13A is a marine dead man alarm panel that monitors operator acknowledgment and initiates a prewarning and alarm sequence when the operator fails to respond. It is used in shipboard alarm and safety systems where continuous watchkeeping is required.
The E-1235 configuration is listed with a K5 dead man timer, K4 prewarning timer, and 0–3 minute timing range. This is legacy equipment, so confirm the suffix, internal timer arrangement, supply voltage, terminal wiring, and vessel-system drawings before ordering a replacement.

Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to This Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No panel indication | Missing control voltage, blown fuse, open common, or internal power fault | ✅ High | Measure the actual DC or AC supply at the KR-13A input terminals against the vessel drawing | Check fuse, polarity, common, and supply wiring before replacing the panel |
| Dead man alarm activates immediately | Timer setting, acknowledgment circuit, or pushbutton wiring fault | ✅ High | Verify the K5 setting and measure the acknowledgment input while pressing the operator control | Check the field pushbutton and timer adjustment before condemning the panel |
| Prewarning operates but final alarm does not | K4/K5 timing relationship, relay contact, alarm output wiring, or external alarm-system fault | ✅ High | Time the sequence with a stopwatch and measure the alarm relay contact during escalation | Inspect relay contacts and downstream alarm wiring |
| No prewarning alarm | K4 timer or prewarning output circuit fault | ✅ High | Initiate a controlled no-acknowledgment test and measure the prewarning output contact | Compare contact operation with the approved system schematic |
| Alarm remains active after acknowledgment | Stuck pushbutton, open acknowledgment return, failed input circuit, or incorrect common | ✅ High | Check continuity and voltage at the acknowledgment terminals during and after button operation | Repair the field circuit; replace the panel only if the input remains unresponsive |
| Timer does not match the original panel | Wrong KR-13A variant or incorrect timer module | ✅ High | Photograph the original label, timer markings, and internal configuration before removal | Match the exact suffix and E-configuration, not only “KR-13A” |
| Alarm output works locally but not at the bridge | Open cable, terminal mismatch, relay contact issue, or remote alarm-system fault | ❌ Low to medium | Test continuity from the panel relay output to the receiving alarm input | Troubleshoot the external circuit before replacing the panel |
| Intermittent alarm during vessel operation | Vibration, loose terminal, degraded relay, moisture, or unstable supply | ✅ Medium | Monitor supply voltage and terminal continuity while gently inspecting wiring under approved procedures | Tighten and inspect terminals; check for corrosion or moisture ingress |
| Replacement causes unexpected alarm behavior | Variant, wiring, timing, or contact-logic mismatch | ✅ High | Compare terminal numbers, normally open/normally closed contacts, timer positions, and supply rating | Stop commissioning and reconcile the replacement against the original drawing |
| Panel appears completely dead after handling | ESD or accidental short circuit during installation | ✅ Medium | Inspect terminals and internal boards; test supply isolation before re-energizing | Use ESD controls and follow marine electrical isolation procedures |
Support note: If the fault remains, contact technical support with photos of the nameplate, timer modules, terminal wiring, system schematic, measured supply voltage, and alarm-test results. Do not bypass a dead man alarm on an operational vessel without written authorization and an approved safety procedure.
Frequently Asked Questions
What does the Autronica KR-13A do?
It monitors operator acknowledgment in a marine dead man alarm circuit. If acknowledgment does not occur within the configured interval, the panel provides a prewarning and then an alarm output.
What are the K4 and K5 timers?
For the listed E-1235 configuration, K5 is identified as the dead man alarm timer and K4 as the prewarning timer. The listed timing range is 0–3 minutes. Confirm the actual timer markings on your panel because KR-13A variants may not share identical internal configurations.
Is KR-13A/Y2H interchangeable with KR-13A/Y6H?
Do not assume so. Public listings identify both variants, but they do not establish identical wiring, timing, supply, relay logic, or certification. Match the complete part marking, internal configuration, terminal diagram, and vessel-system documentation.
Can I install this panel while the system is energized?
Treat it as non-hot-swappable equipment. Isolate the relevant supply, apply lockout/tagout, and confirm zero energy before disconnecting wiring. A live replacement can trigger a false alarm or damage contacts and connected equipment.
Will the replacement retain the original timer settings?
Not necessarily. Timer settings and internal configuration may be physically set on the panel or timer modules. Photograph every adjustment and jumper before removal, then verify the replacement during a controlled functional test.
Is the Autronica KR-13A obsolete?
It should be treated as legacy equipment with limited availability. Current listings describe KR-13A units as used or surplus stock, including an E-1235 variant and other suffix variants. Request the exact unit photos and condition statement before purchase.
Why is a surplus or used KR-13A cheaper than an OEM replacement?
The lower price usually reflects legacy inventory, used marine equipment, or discontinued production rather than current factory supply. Require a clear condition statement—New Original (New Surplus), Factory Sealed, or Refurbished (tested)—along with relay/timer test results, warranty terms, and return conditions.
