Yes, this sounds like the right product.
The Easy Press Call Button is a large red squashy button (10cm in diameter) which is connected to a very sensitive control box. The button can be activated by the lightest of touch, so is suitable for people with limited functional dexterity.
The range between the pager and the control box can be up to 200m.
The button is supplied with 2 meters of tubing so it can be positioned anywhere. The tubing can be cut shorter if needed.
