Description
🔍 Product Overview
The Sam Electronics DAP 2200-ACC is a specialized Duty Alarm Panel (DAP) designed for maritime and industrial monitoring applications. As a key component of the MCS 2200 and MOS 2200 automation series, the “ACC” variant is specifically designated for Accommodation areas, ensuring that critical alarms and system status updates are transmitted from the bridge or engine room to crew living quarters.

🚀 Application Areas
- Vessel Accommodation: Relaying machinery, fire, and safety alarms to crew cabins and public spaces.
- Bridge & Engine Room Integration: Acting as a slave panel for the main MCS 2200 Monitoring and Control System.
- Unmanned Machinery Space (UMS): Essential for maintaining UMS notation by ensuring duty engineers are alerted anywhere on the ship.
📖 Product Usage Instructions
The unit is typically flush-mounted into bulkhead panels or consoles. It features a membrane keypad for alarm acknowledgement and a back-lit display for visibility in low-light environments. Connection to the central system is handled via a redundant system network. Ensure the unit is mounted away from direct heat sources and that all rear cable connections are secured with proper strain relief to withstand vessel vibration.
🌐 Communication Configuration Steps
- IP Address: Configuration is performed via the central MCS/MOS 2200 engineering station. The unit must be assigned a unique IP within the automation network segment (typically 192.168.x.x).
- Station ID: Set the physical node or station number via the internal jumpers or software menu to match the ship’s specific automation topology.
- Baud Rate: The module automatically synchronizes with the redundant system network (CAN-bus or Ethernet-based), usually operating at 500 kbps for fieldbus segments or 10/100 Mbps for Ethernet backbones.
⚡ Power-Up & Commissioning Flow
- Verification: Confirm supply voltage (typically 24V DC) is stable and correctly polarized.
- Cable Audit: Verify that the “Redundant Net” cables (Net A and Net B) are correctly seated.
- Initialization: Upon power-up, the panel performs a self-test; all LEDs should illuminate briefly.
- Network Sync: The unit will search for the master controller. Once the “System OK” LED stays solid, the unit is online.
✅ Initial Operation Checklist
- Check that the display contrast is set for optimal viewing.
- Test the “Lamp Test” function to ensure all visual indicators are operational.
- Verify the audible buzzer sounds upon a simulated test alarm.
- Confirm the panel correctly displays the current “Duty Engineer” status from the main console.
❓ Common Questions (Q&A)
Q: What does a “Comm Failure” message mean? A: This indicates the panel has lost connection to both redundant networks. Check the cabling and the status of the network switches/hubs. Q: Can I change the duty engineer from this panel? A: Typically, duty selection is performed at the Bridge or Engine Control Room (ECR) panel, while the ACC panel is for monitoring and local acknowledgement. Q: Is the unit waterproof? A: The front face is generally rated IP44 (splash-proof), but the rear housing is designed for protected indoor accommodation environments.
