Nurse Call Systems for Hospitals and Clinics: How to Choose the Right Number of Points
Quick answer: A nurse call system lets a patient press a button at the bedside or in the toilet to alert nurses, and shows which bed or room is calling on a display at the nurses' station. To choose one, count the number of call points (beds and toilets), decide between wired and wireless, and check what the central display and sound will look like at the station. Small clinics and nursing homes often need a simple wired system with a point for each bed.
This guide explains how a nurse call or staff call system works, how many points you need, what accessories to plan for, and how to avoid common installation problems in hospitals, nursing homes, clinics and elder care homes.
What is a nurse call system?
A nurse call system is a small communication network. Each bed has a call button. When it is pressed, a central unit at the nurses' station sounds a tone and shows the bed or room number. Staff then go to that bed. The same idea is also used as a staff call system in offices, restaurants and elder care homes.
Basic parts include:
- Bedside call button (patient unit)
- Toilet or bathroom call point (often with a pull cord)
- Door lamp or indicator above the room door, where required
- Central display unit with buzzer at the nurses' station
- Cable and power supply for wired systems
How many call points do you need?
Count one point for every place a patient may need help. Typical places are the bed, the attached toilet and any day-care or recovery area. Add a few extra points for growth. NavKar Systems lists nurse call systems in several sizes, from small ones to larger systems, so you can choose the size that matches your count. See the full range in Hospital Nurse Call Systems.
| Facility | What to count | Points to plan |
|---|---|---|
| Small clinic with a few beds | Beds plus one toilet point if present | Beds + toilets |
| Nursing home | Each bed and each toilet | Beds + toilets + common areas |
| Hospital ward | Beds, toilets, procedure areas | Per ward, with display at each nurses' station |
| Elder care home | Bedrooms, bathrooms, common rooms | Rooms + bathrooms + lounge |
Wired vs wireless nurse call systems
- Wired: uses cable between each bed and the central unit. It is dependable and not affected by radio interference. It is best planned when a building is being built or renovated.
- Wireless: uses radio signals. It is easier to add to an existing building, but you must check radio range, battery replacement and how the system shows which patient is calling.
Check each model's product page for how many points it supports, how the call is displayed, and what accessories are included.
Features to look for
- Clear display of the calling bed. The number should be easy to read from a distance.
- Audible alert. A distinct tone that staff can hear in the station and nearby rooms.
- Reset or cancel option. Staff should be able to clear the call once the patient is attended.
- Toilet call point. Many incidents happen in bathrooms, so include one wherever a patient may need help there.
- Easy-to-press buttons. Patients may be weak or elderly. Choose buttons they can press easily.
- Expandability. Check if you can add points later.
Installation tips
- Plan the cable route before walls and ceilings are finished.
- Keep call cables away from heavy electrical cables, to avoid interference.
- Fix patient buttons within easy reach of the bed.
- Test every point after installation and label each point with the bed number.
- Train nursing staff so they know what each tone means.
Other systems that work alongside a nurse call system
Hospitals and clinics also need a few related systems:
- EPABX or intercom for communication between wards and the reception. Read our EPABX intercom system guide.
- Access control for medicine stores, labs and records rooms. See our door access control guide.
- Fire safety items such as alarms and extinguishers. Browse fire safety products.
- Staff attendance with a biometric attendance machine.

Frequently asked questions
Is a nurse call system only for hospitals?
No. It is also used in nursing homes, clinics, elder care homes, rehabilitation centres and even in homes where an elderly person needs help. Some businesses use the same idea as a staff call system.
How do I choose the right number of points?
Count every bed and toilet that needs a call button, then add a few extra for future use. Choose a system that supports at least that number of points.
Can I add more beds later?
Many systems can be expanded, but the limit depends on the model. If you expect to grow, choose a system with more points than you need today.
Is a wired system better than a wireless one?
Wired systems are reliable and are best for new construction. Wireless systems are easier to retrofit in an existing building. The right choice depends on your building and budget.
Sample layouts by facility size
| Facility | Typical layout | Notes |
|---|---|---|
| Small clinic with observation beds | Bed button at each bed, display at reception | Simple wired system is often enough |
| Nursing home | Bed and toilet call points in each room, indicator lamp in corridor, central display at nurses' station | Add pull cords in bathrooms |
| Small hospital ward | Bed and bathroom points, corridor lamps, display at each ward station | Plan separate zones per ward |
| Elder care home | Bed, bathroom and common room points | Easy-to-press buttons for weak users |
Responding to calls: process matters
- Agree who responds to calls on each shift and how long a response should take.
- Make sure the sound is distinct from other alarms, such as fire alarms.
- Reset calls only after the patient has been attended.
- Test every call point regularly, such as once a week or as per hospital policy.
- Keep a log of faults and repairs.
Cable, power and backup
Nurse call systems must work during power cuts. Plan a backup power source for the central unit and ensure the supply voltage matches the equipment. Use quality cable of the recommended size, and keep it protected inside conduit. For power supply sizing concepts, our power supply guide explains how to add up loads and leave a margin.
Common questions from hospital and clinic owners
Is a nurse call system mandatory?
Requirements depend on the type and size of the facility and local regulations. Check with the relevant authority or a consultant for your case.
Can I use an ordinary doorbell as a nurse call?
A doorbell rings but does not show which bed is calling. A nurse call system identifies the bed or room, which makes responses faster and reduces confusion.
What about bathroom safety?
Include call points with a pull cord or large button near the toilet and shower, where falls are common, and keep them easy to reach from the floor.
How do I choose between 6, 12 and 20 point systems?
Count all required call points, add some for growth, and choose a system that supports at least that number.
