Auth‑Florence MPS‑2 Nurse Call Station is a wall‑mounted patient call interface that integrates a pull cord, call button, and reset switch into a single unit for use with the Auth‑Florence nurse call system. Common failure modes include burned or tripped internal relays, failed contactors on the call/reset contacts, and degraded power supply modules that cause intermittent or no response to patient calls. For this model, check the 24 V DC input rail for continuity and voltage drop across the relay coil; inspect the reset button and call‑placed lamp contacts for corrosion or mechanical wear; and verify the printed circuit board for visible burn marks or broken traces around the power regulator area. Initial diagnostics should include a visual inspection of all connectors, a multimeter check of the 24 V supply, and an error code readout from the system controller if available.[oss-gpt-20b]
