It does nothing and is simply a way to try and deter would be burglars. **Q: What size batteries does it take. And how long do they last** A: AAA batteries either 3 or 4 (can’t remember) apparently lasting up to 3 years! **Q: Can anyone confirm the color of this dummy box, in the picture it's yellow but the discription says white, Thanks.** A: Both the siren & the dummy siren are as shown in the picture - Yellow. I have bought 2 of those & sirens are all Yellow. Both sirens are the same, but the dummy doesn't have the electronics included, so is just an empty "box", but externally identical to the "real" siren. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Realistic Look and Great Deterrent *by B***A on 8 October 2025* The Yale AC-DBX Dummy Siren is a simple but very effective addition to any home security setup.
