A hospital intercom problem is rarely one system. It is the ward call chain from a bed-side station to the carer who answers, plus a talkback position between a control desk and a scanner room, plus a door station at a theatre or an ICU entrance where the person who opens the door is not standing next to it. This page treats all three as one design problem on one IP and SIP network, with the counts from the reference plans already published in the care material and the access-control and paging interfaces named where they are documented. NEXVIA designs, manufactures, supplies and commissions the system; the terminals are manufactured by NEXVIA, including the care and intercom range used throughout this design.
Count the clinical positions, not the square metres. The reference plans in the care material count a 50-bed clinic as 50 bed-side stations, 15 door-side stations, 15 bathroom pull cords, 15 corridor lights, 1 nurse console and 15–20 portable handsets; a 70-bed nursing home as 70 bed-side stations, 70 bathroom call points and 40 corridor lights as an option. Add one talkback position per clinical room and one door station per controlled entrance and the intercom equipment list is complete.
Two-way audio in clinical and ward rooms comes from the speaker family rather than from a promise. The A212 publishes 8 Ω with up to 15 W class D output and talkback through an omnidirectional microphone (PoE 8 W / PoE+ 15 W); the FH-S01 publishes up to 20 W with a built-in class D amplifier, talkback and a customisable WAV for emergency notification, on PoE to IEEE 802.3af. Note the boundary the material draws: two-way broadcast is not supported by the series, so a talkback position has to be a model that publishes talkback.
The physical rules decide whether the design survives contact with a ward: bathroom pull cords put a 2 m cord at floor level (KT30 wireless at IP65, KT31 wired at IP44), wireless buttons link over 433 MHz across 6–25 m indoors with up to 10 buttons on one station, and the nurse console supports up to 20 SIP lines, 116 DSS keys and up to 100 connected devices. Prices are not published on this site — NEXVIA quotes per ward, per room mix and per clinical-room count.
Ward staff are between rooms, not at a desk. The chain widens rather than repeats: the call forwards to a portable handset, speakers amplify it, and the corridor display plus the light over the door identify the room to whoever is passing.
In an imaging or procedure room nobody wants to pick up a handset mid-task. Talkback speakers and hands-free console positions cover that requirement — but only on the models that publish talkback or two-way voice, because two-way broadcast is not supported across the whole speaker series.
Theatre, ICU, pharmacy and records doors are access-controlled as well as intercommed. The door stations carry the relay, the camera and, on the outdoor models, an anti-tamper alarm reported to the control centre, so the release and the call are one event rather than two systems.
A refurbishment cannot always re-cable a working hospital. The options are analog ports on the PBX where pairs still reach the frame (up to 48 on the OM80E and 96 on the OM200G), PN1 converters over two-core cable, and new IP stations floor by floor as wards are released.

Scope. A nurse call system is the ward chain — call points, corridor indication, console and portables. A hospital intercom covers that chain and the clinical positions around it: talkback between a control desk and an imaging room, a door station at a theatre or ICU entrance, a console in a records or plant room, all on the same network.
With a talkback position that is an extension, not a separate product family. The A212 wall speaker publishes talkback through an omnidirectional microphone with up to 15 W class D output, and the FH-S01 ceiling speaker publishes talkback with up to 20 W on PoE to IEEE 802.3af — both reachable by extension number from the control desk.
A theatre or ICU entrance behaves like a building door with a medical priority: an entrance station as an extension, a relay for the strike, a camera for identity and an anti-tamper alarm where the position is exposed.
The console is sized on devices rather than beds: the A320i supports up to 100 connected devices, 20 SIP lines and up to 116 DSS keys, with the corridor displays counted per floor in the reference plans (2 per floor in the clinic plan, 4 in the nursing home plan, both optional).
Yes. Calls transfer automatically to the W611W portable handset when the nurse station is unattended, and ward speakers can amplify the incoming call so the call is heard elsewhere in the ward.
Yes, and that is the documented architecture. The care system is stated as IP and SIP based and integrates with access control and PA systems, and the same PBX carries the site telephony: 24 to 1000 SIP trunks, with extensions numbered from 200 upwards.
Nothing on this page is a certification claim. The published comparison for this care system records no third-party safety certification for the system, and the material does not state any. A compliant clinical intercom design therefore has to be confirmed against the local code by the hospital own compliance officer and engineering adviser before it is tendered.

The ward figures come from the two published reference plans; the clinical room and door rows use the intercom and paging range, whose talkback and contact capabilities are published per model.
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 must state the first seconds: which device rings, how long it rings before escalation, which portable catches it, and which speaker amplifies it. Nurse call, bathroom emergency, staff assist and code blue are separated at the call point with different flash patterns and colour coding, and the console prioritises them. None of those settings is regulation — they are local clinical procedure, and they belong in the handover document and in a ward-by-ward test.
A compliant design starts with the response chain: what a call does in the first 10 seconds, who it reaches, what happens when it is not answered, and what record survives. This page sets out a chain built from IP and SIP terminals with password-gated emergency calls, automatic transfer to a portable handset and exported call and attendance logs. Whether that chain satisfies a particular national or accreditation requirement is a determination the hospital own compliance officer makes against the applicable code — NEXVIA does not assert it, and the published material records no certification for these products.
The bed-side station is the powered node in the room — PoE support per the product guide — and it powers and controls the CL-01 corridor light rather than the light taking its own PoE run. Wireless buttons carry their own batteries (KT30) or need no power (KT31). Ward speakers are PoE: FH-S01 to IEEE 802.3af and the A212 published as PoE 8 W / PoE+ 15 W. The consoles take dual Gigabit ports with integrated PoE. Budget the switch ports per ward, keep the panel schedule with the as-built drawings, and confirm PoE classes and cable classes against the local wiring code before first fix.
Antibacterial detachable buttons are published for the care station range, and the protection ratings that decide where each device may be installed are published per model: KT30 IP65, KT31 IP44, the A12V IP66 and IK10, the i6x range IP66 and IK07. Mounting heights for pull cords and call buttons, cleaning agents that may be used on a device, and the reachability of a call point from a floor are practical requirements the ward staff should confirm on site. Image and door-log data from camera terminals, and any recording of calls, are personal data in most jurisdictions — the retention rule and the notice to patients and staff are the hospital own policy decisions, not equipment features.
