Panel Mounted Main Station

The Zenitel VSP-211-L is the main station with a built-in system amplifier for Zenitel’s 12-way batteryless telephone arrangement. It is a vital choice where the system needs a capacitor-backed amplifier to maintain communication when normal vessel power is lost.

Main benefits and key functions

The 12-position selector enables selective calling between connected main stations. The integrated system amplifier with capacitor battery sets the VSP-211-L apart from the VSP-213-L, while terminals for an auxiliary 24 V DC supply allow common-battery telephone use where specified. Zenitel states that the auxiliary supply must use a DC/DC converter to avoid noise. This role is important at system design stage because the amplifier-equipped station provides a function that the other VSP main station variants are not stated to include.

Typical applications

It is intended for ship wheelhouses and control rooms where reliable secondary communication is part of the onboard safety design. The batteryless approach is valuable for communications resilience during a blackout. Specify this unit for its system-amplifier role rather than treating the VSP models as interchangeable.

Connectivity and installation

The VSP-211-L supports flush console mounting, with optional MBOKS-G wall or VSPC-OAK desk cabinets. Screw terminals provide the system interface. Zenitel specifies an IP44 rating when installed in the console, a -25°C to +55°C operating range and a 205 x 105 mm panel cut-out.

Specification and purchasing guidance

For installers and specifiers, the VSP-211-L should be matched to the host equipment, cabling and operating conditions shown on the project drawings. Keep the model number in the system schedule so future maintenance teams can identify the correct version. Check any optional accessories separately rather than assuming they are supplied with the base product.

Summary

The Zenitel VSP-211-L offers a focused solution for its documented role. Its main strengths are the specific functions and compatibility described above, making it a practical choice when those requirements are part of the installation. Order the exact version that matches the system design.
