How it fits into the alarm platform: 

Connects wirelessly to the BarnTalk Gateway. The dry contact sensor should be placed within ~700 feet of the BarnTalk Gateway. On multi-barn sites, the dry contact sensor’s range can often extend across multiple buildings depending on proximity.

• Can be used to monitor power, generators, controllers, feed lines, water pressure switches, and any equipment with a power relay.
• Included Battery with 2-3 Year Life
• IP67 Waterproof and Dustproof Rated
• Tested for Maximum Durability in Harsh Conditions

BarnTalk is the only wireless barn alarm with certified multi-carrier connectivity built right into the system. Once you plug the BarnTalk Gateway into power, it connects to the strongest local cell tower, regardless of carrier, eliminating the need for a landline, WiFi, or hotspot. BarnTalk sends alarms via push notification, SMS text message or phone call based on the user’s preferences. For optimal alarms and monitoring, you’ll need a BarnTalk subscription. This subscription covers connectivity and data costs.
