Enhance the protection of your family with environmental alarms connected to your home security system. When a flood, smoke, or carbon monoxide detector is triggered, your home’s high-decibel alarm will initiate. Your monitoring specialists will be contacted, and you’ll get a smartphone communication, an important consideration if you’re away. You can even have your smart lock release automatically when a CO or smoke detector activates, facilitating your evacuation.
