SAM  Electronics DAS40M (Geamar duty-alarm unit)

Inputs:

Digital alarm inputs: 24 VDC discrete alarm signals from field sensors, switches and machinery status contacts; accepts both active-high 24VDC and dry-contact passive signals; receives watch-keeping acknowledgement and duty-change status signals from local operating stations; system bus input from MCS-40M backplane for central system communication.

Outputs:

Relay alarm outputs for audible alarm horns, visual alarm lamps and remote alarm annunciators; dry-contact relay outputs for bridge and other remote watch stations; serial back-plane bus output transmitting processed alarm messages and duty-status data to central monitoring system; potential-free relay contacts for alarm forwarding to external ship-automation equipment.

Power input: 24 VDC marine supply.

Compatible Systems & Software:

Host system: SAM Electronics Electronics / Lyngso Marine GEAMAR MCS-40M machinery monitoring & alarm system, connected via proprietary back-plane system bus.

Configuration tool: GEAMAR MCS-40M PC service software (legacy Windows-based commissioning tool) for alarm parameter setting, duty-mode configuration and fault diagnostics.

Compatible peripheral modules: Other GEAMAR series rack-mount I/O modules including analog input and relay output units on the SAM Electronics Electronicse system backplane.

Integration support: Can forward alarm data to third-party ship automation systems via potential-free relay dry contacts; requires gateway unit for Ethernet-based modern ship management systems.

SAM Electronics DAS40M Operating Procedure

Power-on and Self-Test

Apply 24 VDC marine-rated power to the DAS40M unit. The module runs an automatic power-up self-diagnostic routine. Confirm the front-panel display and status indicators light up properly, no hardware fault codes are presented on the LCD, and reliable bus communication with the MCS-40M host system is established.

Normal Watch-Keeping Operation

In standard duty mode, the module continuously scans all field-sourced digital alarm inputs. Upon receiving an alarm trigger, it activates local visual alerts and audible horn outputs, and propagates alarm notifications to the bridge and remote watch-keeping stations through relay contacts and the system backplane bus.

Alarm Acknowledgement

When an alarm is raised, press the front-panel ACK button to acknowledge the active condition. The local audible alarm will mute, whereas visual alarm indication stays active until the original field-side fault is removed. Multiple concurrent alarms must be acknowledged individually.

Duty-Mode Selection

Press the DUTY button to reassign the active watch-keeping station. Ensure the duty-handover signal is transmitted across the system bus; status indicators at remote watch stations shall update synchronously complying with SOLAS watch-keeping requirements.

Alarm Log Review

Select the ALARM-LIST key to access the LCD overview of current active alarms and historical alarm events. Use up-and-down navigation keys to inspect alarm descriptions, timestamps and real-time status details.

Maintenance and Parameter Configuration

With proper authorization, press the EDIT key to open the maintenance menu for adjustments to duty-alarm time delays, output mapping and associated logical settings. Comprehensive parameter editing must be completed using the supporting GEAMAR MCS-40M service software tool.

Functional Simulation Test

In the course of periodic checks, initiate simulated alarm conditions. Validate correct operation of horns, lamp relay outputs, remote station alerts and alarm-acknowledge functions. Return the unit to regular operational mode once testing is finished.

Power-Off Instructions

De-activate associated alarm functions prior to disconnecting the 24 VDC power supply. Unplanned hard power-off should be avoided during normal system operation. After power is restored, the DAS40M automatically reverts to its prior duty-alarm operating state.

Fault Troubleshooting

Should communication errors or hardware faults show on the display, inspect backplane bus connections, power fuses and field terminal wiring, then execute a system reset. If the fault remains unresolved after reset, engage certified marine service technicians for further intervention.
