Description

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.

Make sure your alarm is heard everywhere in your home with the ADT Blu Indoor Siren. At 105dB, this siren is significantly louder than the 85dB speaker built into the Base hub, amplifying the alarm when placed in a different room, hallway, or floor of your home, ensuring that security alerts reach every corner of the house. One-go/All-go technology ensures that when one siren or detector triggers, all connected sirens and detectors in the system sound simultaneously for maximum alert coverage. Place the siren in a bedroom, basement, or upstairs hallway where the Base hub alarm might not be loud enough on its own. The siren features built-in tamper alerts through the ADT+ app that notify you if the device is moved or disturbed, an LED pairing indicator for quick setup with your ADT Blu Base hub, and battery-powered operation for completely wireless installation with no wiring needed. Mount with screws or adhesive tape in seconds. Includes 2 batteries so you are ready to install right out of the box. Add multiple sirens throughout your home for layered audio coverage on every floor. Requires purchase of an ADT Blu base and a paid subscription.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?

Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $12 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.

What's the difference between open-box and refurbished?

Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.

Why use OpenBoxFox?

Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for ADT Blu products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.

Is it safe to buy refurbished?

Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
