A nurse call system is judged by one thing: whether the right carer reaches the right room, in time, with a record of what happened. The system documented here is IP and SIP based and is assembled from four parts — call points, corridor indication, a nurse console and portable handsets — with no proprietary bus and no separate server room. This page follows a call from the pull cord to the answer, and gives the counting rules for a ward, a clinic and a nursing home. NEXVIA designs, manufactures, supplies and commissions the system; the terminals are manufactured by NEXVIA.
A nurse call system for a ward is counted per bed and per call position, not per patient: one bed-side station per bed, one bathroom pull cord per bed or bathroom, a door-side station where code blue at the door is required, and one console per nurse station. The two reference plans printed in the care material count exactly that way — a 70-bed nursing home as 70 bed-side stations, 70 bathroom call points, 1 console and 15–20 portable handsets; a 50-bed clinic as 50 bed-side, 15 door-side, 15 bathroom points, 15 corridor lights and 1 console.
The chain has four links and every one of them is a network terminal: the call point raises the call, the corridor light over the door and the corridor display identify the room, the console answers with priority and colour coding, and a portable handset catches the call when nobody is at the station. The console supports up to 20 SIP lines, up to 116 DSS keys and up to 100 connected devices, and emergency calls require a password before the connection is made, so a person answers.
The physical rules decide whether it works on the day: bathroom pull cords put a 2 m cord at floor level, the wireless option is IP65 with its own battery and a 433 MHz link across 6–25 m indoors, and one bed-side station hosts up to 10 wireless buttons. Prices are not published here — NEXVIA quotes per ward count, room mix and the cable already in the building.
A call that only rings the station fails as soon as the ward is busy. The chain widens instead: speakers can amplify the incoming call, the corridor display and the light over the door identify the room, and the call forwards to the W611W portable handset when the station is unattended.
Nurse call, bathroom emergency, staff assist and code blue are different events with different urgency. The system separates them at the call point, shows them with colour and flash patterns, and prioritises them on the console with colour coding.
Every bed, every bathroom and every door position is a device, and bathroom points are radio or wired depending on the building. The two reference plans count them explicitly — 50 bed-side and 15 door-side in the clinic, 70 bed-side in the nursing home — so they can be used as the template for a new ward.
Care providers need a record of who called and who attended. The console keeps call and attendance logs that can be viewed and exported, and the PBX can record calls in G.711 and G.729 where a recording server is part of the design.
| Size band | System | Devices | Notes |
|---|---|---|---|
| Care home — up to about 40 rooms | OM50G — 62 SIP trunks | One bed-side station per bed, one bathroom call point per bed, 1 × A320i console, 15–20 portable handsets | Scale the 70-bed ratios down to the room count. Ring groups hold up to 40 extensions on this model; capacity is published in SIP trunks because the maximum extension count is not stated. |
| 50-bed clinic — 10 four-bed and 5 two-bed rooms, 3 shifts | OM1000-UC — 1000 SIP trunks, up to 200 concurrent calls per trunk | 50 × Y501W-Y bed side, 15 × Y501W door side, 15 × KT30/KT31, 15 × CL-01, 1 × A320i, 15–20 portables, 2 × CMD-01 per floor optional | Counts are the clinic plan printed in the care material; the corridor display and light quantities are marked optional there. The plan does not name a PBX model, so the model is a reference choice. |
| 70-bed nursing home — 10 single and 30 double rooms | OM200G — 496 SIP trunks | 70 × Y501W / Y501W-Y bed side, 70 × KT30/KT31, 1 × A320i, 15–20 portables, 40 × CL-01 optional, 4 × CMD-01 per floor optional | Counts as printed in the nursing-home plan: one bed-side station per bed and one bathroom call point per bed. Confirm the final bed and room counts, and the optional corridor items, on the quotation. |
| Hospital — several wards or buildings | OM1000-UC — 1000 SIP trunks | The per-ward counts repeated, one console per nurse station, 2–4 corridor displays per floor | SIP only, with dual hot standby and multi-site networking between buildings; the care material does not state a maximum number of stations per system. |
| Extension wing or refurbished floor | OM200G — 496 SIP trunks | New IP stations on the network, with existing analog call wiring terminated or bridged where pairs still reach the frame | Up to 96 analog ports on 24-line interface cards suits a wing that keeps part of its old wiring; PN1 converters cover rooms with two-core cable only. |

Four parts, and all four have to be in the design: the call points (bed side, door side, bathroom and wireless buttons), the annunciation (a light over each door and a corridor display), the answering station (the console at the nurse station), and the portables that carry the call to a carer who is not at the station.
No. The call points are network terminals: the Y501 series station has PoE support per the product guide, and it powers and controls the corridor light over the door, so one network run serves the station and its indication rather than a second cable for the lamp.
The dome light is the light over the room door that shows a call without anyone reading a screen. In this range it is the CL-01 corridor light, mounted above the door in an 86 box or on the wall, powered and controlled by the bed-side station in that room.
Three for a full care room and two as a minimum. The published count is one bed-side station per bed, one bathroom call point per bed or per bathroom, and a door-side station where code blue at the door is required. A 4-bed room therefore carries four bed-side stations before any corridor items.
The call moves rather than waiting. It transfers automatically to the W611W portable handset when the station is unattended, and ward speakers can amplify the incoming call so staff elsewhere in the ward hear it.
Yes, if the existing system is SIP based: the stations and console register as SIP terminals like any other extension, and the console takes 20 SIP lines. The care system is documented as IP and SIP based with no proprietary server requirement.
The wireless buttons use a 433 MHz link with a published working range of 6–25 m indoors, and up to 10 buttons can be paired to one bed-side station. KT10 and KT20 are self-powered (no battery) and KT30 carries its own battery.
Integration with access control and PA systems is one of the headline points of the care material, and the same range includes door phones with remote unlocking and SIP speakers for zone broadcasting. Bring those interfaces into the enquiry so the wiring and the extensions are designed together.
Alert indication as stated in the care material
| Signal | How the system shows it |
|---|---|
| Nurse call | Slow flash on the station |
| Bathroom emergency call | Quick flash |
| Staff assist call | Slow flash |
| Code blue | Quick flash |
| Staff presence | Indicated on the station |
| Corridor light (CL-01) | Red, green, blue and yellow to indicate different statuses |
| Corridor display (CMD-01) | Room and call information, with up to 30 prioritised messages |
| Ward speaker (FH-S01 / A212) | Amplifies the incoming call when the station is unattended |
Multiple alert methods are used together: incoming calls can be broadcast through speakers, colour and flash pattern indicate the call type, and the corridor display shows the call information. The design decision is which of them is primary in which ward.
The two published plans are useful less as equipment lists than as a ratio. Read them as: one bed-side station per bed, one bathroom call point per bed, one door-side station per room where code blue at the door is needed, one console per nurse station, and 15–20 portables per site regardless of size.
Ratios are a starting point for a survey, not a substitute for one. The final count is confirmed on the quotation.
The published behaviour is that emergency calls require a password before the connection is made, so the call is answered by a person rather than auto-connected. Around that, the design has to say what happens in the first seconds: which device rings first, how long it rings before escalation, which portable catches it, and which speaker amplifies it. None of those settings is regulation — they are local procedure, and they should be written into the handover document and tested ward by ward.
The bed-side station is the powered node: PoE support per the product guide, and it powers and controls the CL-01 corridor light. Wireless buttons are self-powered or battery-fed, and the wired pull cord needs no power of its own. PoE classes, cable classes, mounting heights for pull cords and the 86 box standard are local installation matters — confirm them against the applicable wiring code before first fix.
A call point that cannot be reached is not a call point. The bathroom options both place a 2 m pull cord at floor level so a person who has fallen can still reach it; KT31 is IP44 and KT30 is IP65, which decides where each can be installed. Button and station positions, the height of the corridor display and the readability of the light over the door should be checked on site with care staff rather than taken from a drawing.
The published comparison for this care system records no third-party safety certification for the system, and this page makes no certification claim. National rules on call-system performance, alarm interfaces to a fire panel, and the retention of care records differ by country and by facility type. A compliant design is one that has been checked against the local code and the facility's own care policy by the buyer's compliance officer — use this page as the technical input to that review, not as its conclusion.
