I have just completed a new install of Elk m1 gold with 2 keypads. One keypad is the new Navigator touch screen model. This new keypad appears to work fine except for a substantial time delay for a response when touching the buttons for basic functions (like arming the system). After touching the arm button it will take 30 seconds before the screen shows that something is happening. I have upgraded the panel to the latest firmware. Is the normal? If not what next? (my other keypad is m1kp2 and response at that keypad is instantaneous)
