TTDM-128 Alarm Panel
nVent RAYCHEM TraceTek TTDM-128 is an alarm panel that directly monitors up to 1500 m (5000 ft) of sensor cable and a network of up to 126 remote TraceTek modules. These may be a combination of sensor interface modules (TTSIM), relay modules (TT-NRM) or additional TTDM-128 modules. Each sensor circuit detects, locates and tracks leaks independently from any other circuits connected to the module. When leaks are detected, the module sounds an alarm, closes relay contacts, turns on a front panel LED, and displays the circuit identification and location on the alphanumeric display.
