The TTSIM1A Sensor Interface Module monitors up to 500 feet (150 m) of TraceTek sensing cable. With its internal alarm relay and front panel LED status indicators, the TTSIM1A can be used as a
standalone leak detection alarm or it can be connected to a TraceTek SIM network, Distributed Control System or Building Management System. When liquid is detected, the TTSIM1A activates its alarm
relay and can provide accurate leak location information to a host system using standard MODBUS, Opto22, or Johnson Controls Metasys protocol. Although massive sensor cable systems are possible
with networked TTSIM1As, 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.
