I am selling a used security system panel from ADT. The model number is 3G2075-SM-NA. It works perfectly but is no longer needed. The photos are of the exact item you will be receiving. This listing is for the control panel only. I am selling the transformer in a separate listing. I will ship it the next business day after receiving payment, so you will get it fast! I have 100% positive feedback, so buy with confidence. If you have any questions, please feel free to reach out. Thank you for looking!
