Honeywell XS100-CSSK-A, Smart X-Series Smoke Detector (Optical), Alarm Scan App, Battery-Powered

The Honeywell XS100-CSSK-A is a wireless optical smoke detector with a sealed housing, protecting it from adverse conditions. The device performs automatic self-diagnostics to ensure it is functioning correctly. You'll appreciate the very easy installation, simple operation and discreet design. LED lights indicate the detector's status. A clear indication will alert you to a low battery, an alarm, or a device fault. If smoke is detected, a loud 85dB alarm will sound. The Honeywell detector can be paired with the XW100 wireless communication module (not included) to connect up to 32 units or to communicate with the detector using a smartphone.
