Digital Key Control Box for Companionway hatch on CNB76 and CNB66 – NL2070

Description of the control box NL2070 The NL2070 is a high-performance electronic key box designed to manage secure access aboard CNB 76 and CNB 66 sailing yachts. Specifically configured for NOVAL’s companionway hatch systems, the unit enables users to lock or unlock the access via internal or external buttons or by presenting a valid digital key. The system is delivered with three digital keys (AT4358) already paired, allowing for instant functionality out-of-the-box. Its design allows for pairing up to 10 keys simultaneously and features an intuitive LED feedback system, enabling straightforward diagnostics and status indication. The NL2070 operates in lock/unlock modes based on door status, ensuring safety by preventing locking while the hatch is open. Integrated into the yacht’s electrical system, the NL2070 ensures seamless operation and integrates with the locking mechanism through dedicated wiring harnesses.
