An alarm you can’t ignore
The indoor siren is loud enough to hear throughout large homes and is great for heavy sleepers.
Install it virtually anywhere in your home and rest easy knowing you'll be alerted during an emergency.
The Indoor Siren syncs with the ADT Base and the ADT+ app to help provide an additional layer of peace of mind.
You have questions, we’ve got you covered
What is this product?
The Indoor Siren reinforces the alarm sound of your devices whenever any sensor or detector paired to your system is triggered. Conveniently place it around your home to help amplify alarm sounds.
What are the key features?
Key features include:
- The Indoor Siren amplifies an alarm that is set off, along with the ADT Base, when a sensor is tripped
- The alarm siren is 85dB at 10 feet
- The siren provides different sounds for different alarm types: burglary (default siren), smoke (3 beep cadence), CO (4 beep cadence), and panic alarms.
How do I install it?
The device is wireless and can be mounted on a wall or ceiling using the included double-sided tape or optional screws. It uses 2 CR123A batteries. Place it away from your ADT Base to extend the audible sound of an alarm event, or near an entry to scare away intruders. Visit our support article for step-by-step instructions.
What happens if my Wi-Fi or power goes down?
The ADT Indoor Siren is wireless and uses 2 CR123A batteries. It works in tandem with the Base. The Base includes a backup battery for power outages, but if you have Pro-Protect with ADT 24/7 professional monitoring, communications may still be disrupted if your router and internet communications do not also have battery backup, or if the system’s communication path is impaired.
