WATCH TIMER PANEL CARD NAV. SAF
The Norcontrol Watch Timer Unit (WTU), referenced under part number HA446069A, is a dedicated panel card designed for navigation safety and bridge watchkeeping applications. As a core component within Norcontrol Automation’s marine control system architecture, this unit functions as the timing and alert interface that monitors officer-of-the-watch activity, triggering alarms when acknowledgement intervals are exceeded. It plays a critical role in maintaining continuous bridge watchkeeping standards and supports compliance with navigational safety requirements onboard commercial and offshore vessels.
Key Features
✓ Functions as a Watch Timer Panel Card, monitoring watchkeeping intervals and generating navigation safety alerts when reset acknowledgement is not received within the configured period.
✓ Referenced under multiple hardware identifiers including HA446069A and HA332338B/B/C, indicating compatibility across applicable Norcontrol system revisions — exact configuration subject to confirmation against vessel-specific documentation.
✓ Designed for integration within Norcontrol Automation AS marine control and alarm monitoring systems; compatibility with specific panels or controllers should be verified against the installed system configuration.
✓ Intended for installation in the bridge or navigation control environment; mounting location and environmental ratings are subject to the vessel’s original system layout and applicable classification requirements.
✓ Replacement of this card restores watchkeeping timer functionality to the navigation safety system — a direct swap with the correct hardware revision is recommended to ensure system continuity.
Marine Applications
✓ Bridge watchkeeping and navigation safety alarm systems aboard deep-sea cargo vessels and bulk carriers.
✓ Integrated alarm & monitoring systems on offshore supply vessels and platform support vessels requiring continuous watch management.
✓ Navigation control panels on RoRo ferries and passenger vessels where uninterrupted officer alertness monitoring is operationally critical.
✓ Tanker bridge management systems where navigation safety compliance and watch timer integration are essential to safe passage operations.
✓ Refit and spares replenishment programs for vessels operating Norcontrol Automation control system installations requiring like-for-like panel card replacement.
