ADT Blu Indoor Siren, 105dB Alarm Extender, Wireless, Plan Required

• Extend your alarm to every room at 105dB, significantly louder than the 85dB Base hub alone: Place the Indoor Siren in a different area of your home to ensure the alarm is heard clearly throughout the entire house, including upstairs and basement.
• One-go/All-go technology: When any connected siren or detector sounds, all sirens in the system activate together so you are alerted no matter where you are in your home during an event.
• Tamper-proof design with ADT+ app alerts: The siren notifies you instantly through the app if it has been moved or tampered with, ensuring your whole-home alarm coverage remains reliable.
• Easy DIY installation with no wiring: Mount with screws or adhesive tape. Battery powered with LED pairing indicator for quick setup. Includes 2 batteries so you are ready right out of the box.
• Works with ADT Blu system and professional monitoring: Amplify your Base alarm throughout your home. Requires purchase of a compatible ADT Blu Base and a paid subscription plan.
