A wireless call button placed at each floor gate sends a signal to the control panel mounted in the hoist/lift. This lights up the corresponding floor number on the panel, informing the hoist driver where to go.
Once the driver has attended that floor he simply presses the lit floor button to clear the light. The call panel also indicates which button was pressed first, and ignores repeated presses when received. The wireless call buttons have a range of 100 metres in free air with direct line of sight. Generally, buildings over 20 floors will require a signal repeater to be fitted - this will double the range again. Up to 4 repeaters can be fitted.
Many companies have benefited from Easycall systems. The speed of installation and simple set up are highlights.
