Wireless Dry Contact Sensor

The ALTA Wireless Dry Contact Sensor detects when there is contact between the two wired end points. It can
easily be integrated into existing switches or contact plates. When the sensor detects contact between the two
end points a wireless communication is immediately sent to the gateway.

The gateway will immediately attempt to securely send the message to iMonnit, or other approved data services.
