Help from anywhere in the room
Mounted on the wall or worn on a lanyard, the button sits exactly where the person is — bed, bath, toilet or chair — so a call for help is always within reach.
Supplying wireless calling systems in Africa since 2012
Wireless single key button · 100% waterproof
Put a call for help within reach of the person who needs it — waterproof, easy to press and identified by every receiver on the system.

Residents in bathrooms, toilets and showers are exactly the people most likely to need help — and exactly the places where most buttons cannot survive.
And a button that takes strength or dexterity to press is no button at all for someone elderly, frail or with limited hand mobility.
The B-A1-WL is 100% waterproof, so it goes where the person goes — mounted next to the bed, in the bathroom, in the toilet, or worn on a lanyard. A light press on the large soft-rubber surface raises the call, and its unique code tells every receiver exactly where it came from.
Mounted on the wall or worn on a lanyard, the button sits exactly where the person is — bed, bath, toilet or chair — so a call for help is always within reach.
A single Call Button can be programmed to an unlimited number of receivers, so one press alerts as many staff devices as needed — nobody misses the call.
Each button has a unique code/address, so receivers identify which button was pressed — the right person can be sent to the right place, first time.
The large soft-rubber surface activates with a light press — no force needed. That makes it particularly easy for elderly or frail people and people with limited hand mobility.
A light press on the large soft-rubber surface sends the call wirelessly over 433.95 MHz — from a wall, a bedside or a lanyard, even where water exposure is possible.
Because of the unique code/address, every receiver programmed with the button knows exactly where the call came from.
A compatible BellMe Cancel Button clears the call — and because receivers are unlimited, a single Cancel Button can serve many Call Buttons.
The B-A1-WL is used in hospitals, retirement and frail care units and homes — mounted next to beds, in bathrooms, toilets and showers, or worn on a lanyard by residents who are still mobile. Below, see it doing its job in real facilities.

The detailed controls for capacity, identifying calls, mounting and powering the B-A1-WL.
A single Call Button can be programmed to an unlimited number of receivers, so one button can alert multiple devices simultaneously.
Each Call Button has a unique code/address that allows receivers to identify which button was pressed.
The Call Button is 100% waterproof and can be used in showers, toilets, bathrooms and other areas where water exposure is possible.
Mount it with two screws or double-sided tape — a mounting bracket is supplied with every Call Button. It can be fixed to any flat surface, including higher-risk areas such as bathrooms and showers.
A lanyard can be attached to the rear mounting section, so the resident or patient can carry the button with them rather than being restricted to a fixed location.
The large soft-rubber surface is activated with a light press — particularly easy to use for elderly or frail people and people with limited hand mobility.
Each Call Button uses one A23 battery.
