Kidde Battery Powered Smoke Alarm Detector New in Box 20SDR Self Testing

For sale is this new in the box Kidde residential smoke alarm/detector. I have taken it out of the box for the pictures, but it has never been used. This is model 20DRS and uses 2 AA batteries, which are included. This item is described as follows: Key Features: Enhanced Sensing Technology: It uses photoelectric sensors to reduce false alarms often caused by everyday cooking. Fast Alerts: Upon detecting smoke or fire, the unit emits a loud 85-decibel alarm and features a flashing red LED light. Self-Testing: The alarm includes internal components that perform regular self-tests to ensure it is operating correctly. Easy Installation: It is designed for simple surface mounting on walls or ceilings using a twist-and-click mounting bracket. Battery Information: This particular model operates on two replaceable AA batteries, providing continual detection even during power outages. It features a low-battery indicator that emits one chirp and an amber flash per minute when the batteries need. This comes from my smoke free home.
