Wired or wireless nurse call: in a new building, we recommend wired, as conduits are planned from the drawings and the system does not depend on batteries or radio. In renovation, wireless reduces work but requires a radio study and battery monitoring. In both cases, details depend on the product: we separate what is general from what varies by brand and model.
In short
- Wired: no batteries or radio, but wiring is required, simple in new builds, heavy in renovation.
- Wireless: little work, but batteries to monitor, radio coverage to study and possible interference.
- Battery autonomy, radio frequency, number of elements per receiver: all depend on the product.
Wired or wireless nurse call: the comparison
This table gives general principles. The number of batteries, radio frequency and limits vary by product.
| Criterion | Wired | Wireless |
|---|---|---|
| Reliability | No radio link; main risk: cable cut during work | Depends on radio coverage and battery condition |
| New building | Conduits planned in drawings: single | Possible, rarely needed |
| Renovation | Bleeding, false ceilings, dust in occupied site | Little work, prior radio study |
| Maintenance | Regular testing of points | Regular testing and battery replacement |
| Batteries | None for nurse‑call points | One or more per emitting element, depending on the product. |
| Interference | Low sensitivity | Shares the clinic’s radio environment |
| Scalability | Addition = pull a cable, easy with reserve conduits | Add = associate an element, with a limit on number per product. |
New building and renovation
In new construction, the architect and design office can reserve conduits, ducts, and technical rooms. Wiring is pulled before partitions and false ceilings: this is the case where cabling is simplest.
In renovation, it depends on access to ceilings and partitions. If false ceilings are accessible, cabling remains possible. If opening walls in an active clinic is impossible (noise, dust, occupied rooms), wireless merits a study, with on‑site radio tests before any decision.
In wired systems, distances also matter: on Legrand Mosaic, the technical guide limits the link between the management module and the door block to 50 m in 6/10e pairs and 100 m in 9/10e pairs. These limits determine the placement of management modules in the building.
Batteries, interference and maintenance
Wireless adds a task: replace each element’s batteries. Lifespan depends on product and temperature; heat from false ceilings can reduce it. Check that the unit signals low battery before a call point stops working.
On the radio side, reinforced concrete, metal conduits and elevator cages attenuate the signal. A clinic also concentrates Wi‑Fi, cordless phones and other radio equipment: the product’s frequency band and interference tolerance are verified on its technical sheet.
The wired system avoids these issues, but a cut cable is not always obvious without testing.
Radio tests before decision.
A serious radio test is performed on site, with the intended equipment, and covers every real location: bed in position, bathroom door closed, rooms at corridor ends, floors separated by concrete slabs. A test on a single room proves nothing for the others. It is repeated after finishing works, because partitions, false ceilings and metal furniture change propagation.
Our opinion, and its limits
- New building: wired, with reserve conduits.
- Renovation with ceiling access: wired first.
- Renovation without possible access: study of wireless, with radio tests.
- Extension of an existing system: same technology as the existing one, unless the manufacturer advises otherwise.
We install Legrand Mosaic. The Legrand technical guide March 2026 describes only a wired installation, copper pairs between the management module, door blocks and call points, and mentions no wireless version of Mosaic. The Mosaic references we sell, such as the non‑indexed magnetic connection socket for single call operator and the 24 V power supply (ref. LEG078289), fall under this wired installation: that may guide our opinion. If your project requires wireless, we will honestly tell you if a solution fits.
Frequently asked questions
Is wireless less reliable than wired?
Not by principle: the risks differ. Wired is exposed to cable breakage, wireless to weak battery and radio issues. Reliability depends on product design, study, and maintenance.
Can wired and wireless be combined?
It depends on the product: some manufacturers offer both technologies, others only one. For Legrand Mosaic, the consulted guide describes only wired. Ask before buying.
Can the clinic Wi‑Fi disturb a wireless nurse call?
It is possible if both use the same frequency band. The product must specify its band and interference tolerance. An on‑site test remains the best verification.
