Mennen Medical 261-055-010 Nurse Station Selector MR-5142 110V 33W Enclosure

Mennen Medical 261-055-010 Nurse Station Selector MR-5142 110V 33W Enclosure

The Mennen Medical Inc 261-055-010 is a Nurse Station Selector enclosure — part number MR-5142 — designed for use with Mennen Medical nurse call and patient monitoring systems. The unit houses a multi-relay PCB that routes call signals between patient bedside stations and the central nurse station, allowing nursing staff to receive, acknowledge, and route patient call events. It connects via a 10-pin-shell plug (P/N 116-100-139), I/O signal cable, and keyboard cable, with a wiring schematic diagram sheet retained inside the enclosure lid for field reference.

Applications

Mennen Medical Inc was a Clarence, New York–based manufacturer of patient monitoring and nurse call equipment active from the 1970s through the 1990s. The MR-5142 Nurse Station Selector was designed for installation in hospitals and clinical care facilities as a central routing and selection component in a nurse call system — the type of infrastructure that allows patients to signal for nursing assistance from the bedside and allows nurses to respond, prioritize, and cancel calls at a central station. This class of equipment was typically hard-wired into the facility's structured cabling and interfaced with bedside call buttons, corridor lights, and the central nurse station annunciator panel. Units like this were standard in acute care, long-term care, and surgical recovery environments where rapid call acknowledgment and clear signal routing were critical to patient safety workflows. Today, this unit is of interest to facilities maintaining legacy Mennen Medical nurse call infrastructure, biomedical engineers sourcing replacement or repair parts, prop and set departments working on medical-themed productions, and collectors of vintage medical electronics.
