Noise-cancelling Main Station

The Zenitel VSP-223-L is a 12-way batteryless telephone main station designed for clear emergency communications in noisy vessel areas. It adds useful alerting and noise-compensation functions to the core VSP batteryless telephone range.

Main benefits and key functions

A noise-compensated microphone is a key difference from the VSP-213-L and VSP-211-L. The VSP-223-L also provides front LED call indication, an alarm stop button and a built-in relay latch timer for external 24 V DC audible or visual signalling. Its 12-position selector supports direct selection of connected stations when normal power is unavailable. The front-facing call indication and the choice of an external signal are valuable where engines and machinery may mask a normal ringing sound. The additional alert hardware must be selected and wired for the intended vessel.

Typical applications

The model is aimed at engine rooms, thruster rooms, steering gear spaces and ship control positions. Visual call indication supports operators where an audible ring may be difficult to hear, while external signal connections help designers present calls using the appropriate site alarm devices.

Connectivity and installation

Flush mounting is standard. Optional metal and wooden cabinets allow wall or desk installation. The station has screw-terminal connections, an IP44 rating and an operating range from -25°C to +55°C. Select this version where the noise-cancelling microphone and alert controls are essential, rather than the simpler VSP-213-L.

Specification and purchasing guidance

For installers and specifiers, the VSP-223-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-223-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.
