The “wire-free” R130 Dry Contact Sensor monitors dry contact devices without the deployment and cost limitations of traditional wired solutions.

The R130 Dry Contact Sensor features two twisted wires that enable connection to a dry contact device. Once connected, the R130 will monitor and report the open and closed states of the device. While the connected device is in either an open or closed state the sensor will beacon the dry contact status once every 10 seconds. When the dry contact state changes the sensor will immediately broadcast three beacons at 0.5 seconds apart with the new dry contact status then return to beaconing once every 10 seconds. The R130 sensor can be mounted using either the industrial-strength adhesive backing or by using the supplied plastic screw mount. The R130 Dry Contact Sensor cases are impact-resistant and temperature stable. The R130 sensor battery life is typically 5-7 years with a 10-second beacon rate with no more than 250 switching cycles per day.
