The TTSIM1 Sensor Interface Module monitors up to 5000 feet (1500 m) of TraceTek sensing cable. When liquid is detected, the TTSIM1 unit communicates either with a TTDM128 Master Module or directly
to a PLC, Building Management System, or other host system using standard MODBUS, Opto22, or Johnson Controls Metasys protocol. Although massive sensor cable systems are possible with networked
TTSIM1s, their low cost makes it economical to build very robust systems with many small independent sensing cable segments. No field calibration is required other than a map to show where the
sensor cable has been installed.
