  1. Verify the required alarm type and applicable certification for the location.
  2. Check whether carbon monoxide detection is explicitly included.
  3. Confirm interconnection compatibility and behavior without internet.
  4. Follow the manufacturer instructions for placement, testing and replacement.

Gas Detectors

Gas detectors are designed for specified gases. A device for one gas must not be assumed to detect a different gas, and connected notifications do not establish detection capability.

Sirens

Connected sirens provide an audible or visual alert when triggered by a supported controller or device. Trigger compatibility and power backup determine how the alert system behaves.
