The top LED lit on the keypads with no functionality indicate they are not getting correct power. Replacing the power supply would be the solution. Just make sure there are no more than 10 keypads on the keypad link. If a 4 series processor you will also need to consider link 8 as well. The plug in power supply on a 4 series processor supplies power to link 6 and 8. So an RF repeater on link 8 would take some of that power as well. A repeater connected to link 8 takes the same amount of power as 1 keypad. The model number of the power supply is a T120-15DC-9-BL. You will need to contact a Homeworks professional to get the power supply.
