What is true of this model and changes how you fix it
- What it isA smoke-only detector (model SSS5R0) that operates continuously, independent of whether the security system is armed or disarmed, and sounds locally plus alerts the Base — and, if professionally monitored, the ADT Monitoring Center.
- Does not detectThis is the smoke-only model — it is a different physical device from ADT's Carbon Monoxide Detector, Heat Detector, and combined Smoke and Carbon Monoxide Detector, not a shared platform with a software difference.
- PowerThree CR123A batteries, included.
- What owners run intoReports include chirps from a low battery, false alarms from dust or cooking steam and a detector near the end of its ten-year life.
- How to approach a faultReplace the battery, clean the detector gently and replace one that is about ten years old.
- ChirpsA single chirp every minute is usually a low battery, and chirps at the end of life mean the detector has expired. Check the date on the back of the unit.
- False alarmsDust, insects and cooking steam trigger detectors. Clean them gently with a vacuum brush and keep them away from kitchens and bathrooms.
- TestingPress the test button until the alarm sounds, with the monitoring company told first. Plan an escape route and a meeting point so everyone knows what to do.
- Maintaining a detectorTest it monthly, clean it twice a year with a vacuum brush and replace the battery when the panel says. Write the installation date on the back and replace the detector after about ten years. Never paint over it and never remove its battery to silence a nuisance alarm.
- Interconnected alarmsIf one detector goes off, the others on the system may sound too. Silence by finding the one that detected smoke, which usually has a flashing light, and check the panel for the zone. Never ignore a smoke alarm, and make sure every sleeping area has a working one.

Exact questions
Questions that only have an answer for the ADT Smoke Detector
Does the Smoke Detector also detect carbon monoxide?+
No. ADT sells this as a smoke-only model (SSS5R0), physically separate from its standalone Carbon Monoxide Detector (SSCO5R0), Heat Detector (SSHE5R0), and the combined Smoke and Carbon Monoxide Detector (SSSX5R0) — installing this model alone does not cover CO.
Does the Smoke Detector stop working when the system is disarmed?+
No — ADT states this detector operates 24/7 independent of the system's arm state, unlike intrusion sensors such as the Door/Window Sensor or Motion Sensor, which are only actionable while the system is armed.
How long does a smoke detector last?+
About ten years.
Why does it chirp?+
A low battery or end of life.
