+* [Battery](#battery-specification)
+* [Troubleshooting](#troubleshooting)
+
+## Capabilities
+
+* **Smoke Detector** - measure smoke and optionally carbon monoxide levels
+* **Carbon Monoxide Detector** - measure carbon monoxide levels
+* **Sensor** - detects sensor events
+* **Battery** - defines device uses a battery
+* **Health Check** - indicates ability to get device health notifications
+
+## Device Health
+
+First Alert Smoke Detector and Carbon Monoxide Alarm (ZCOMBO) is a Z-wave sleepy device and checks in every 1 hour.
+Device-Watch allows 2 check-in misses from device plus some lag time. So Check-in interval = (2*60 + 2)mins = 122 mins.
+
+* __122min__ checkInterval
+
+## Battery Specification
+
+Two AA 1.5V batteries are required.
+
+## Troubleshooting
+
+If the device doesn't pair when trying from the SmartThings mobile app, it is possible that the device is out of range.
+Pairing needs to be tried again by placing the device closer to the hub.
+Instructions related to pairing, resetting and removing the device from SmartThings can be found in the following link:
