SS3 Keypad - Keeps Lighting Up in an Infinite Loop

Hi all,

Just upgraded to SS3 and still learning how to use it and understanding all the features.

I noticed that my keypad keeps lighting up, dimmed, turning off, and then lighting up again continueously all night long.

By this rate, my battery will be dead in a couple of days.

Any ideas what's going on here? Does the keypad have a motion sensor or some sensor to detect people thus lighting up?

I know that it lights up when I put my hand close to the keypad, but it is lighting up looping even no one near it.

Is it a defect keypad that Simplisafe just shipped to me?

Please advise.

Thanks
