[easygates]

Does anyone know if it is possible to increase volume of this unit ?
When button is pressed at gate .Volume of alert is so low it cannot be heard throughout house..........!

Hi, on the monitor inside the house there is a volume control dial on the bottom, on the right next to the on / off switch. it is the first dial of the 3. try increasing that to see if it changes the volume of the alert.
