Now you can monitor critical conditions at remote locations without running wires. Introducing the 2800 with Wireless Sensor Technology. Based on proven remote monitoring methods, the 2800 adds the ability to read sensor status from wireless sensors; and not just simple on/off status or open/closed conditions. The Wireless Technology includes full analog capability so real world values can be monitored such as actual temperatures, real tank levels, and flow rates. You can use up to four of the wireless sensors with the 2800. A variety of wireless sensor types are available to choose from, including temperature, humidity, power failure, motion detector, water on the floor, etc. In addition to the wireless sensors, there are also two Wireless Interface modules. These allow you to connect to existing equipment or sensors and transmit their status back to the 2800 wirelessly. There is a Dry Contact wireless module, and even a 4-20mA wireless module. The 4-20mA wireless module provides battery backed 24 VDC loop power for your transducer. Most of the Wireless Sensors run on batteries for up to 3 years. The Wireless Sensor Network is always being watched by the 2800. In addition too looking for alarms from the sensor values, it is also looking to make sure that each wireless sensor is fully functional and its batteries are full. If there are any problems with the wireless sensors, the 2800 will initiate a diagnostic alarm and notify the appropriate personnel immediately.
