The System Sensor 5151 Series II 2-wire heat detectors combine Rate-of-Rise and Fixed Temperature operation to provide a reliable detection of Heat produced by fire. These detectors provide open-area protection and are designed and manufactured to comply with AS 7240.5-2004.

Model 5151AUS:
A Low Temperature Heat detector featuring Fixed Temperature operation, for use in areas normally below 50°C, where rapid ambient temperature changes may occur. The 5151AUS replaces the 51B51 detector.
Model 5151RAUS:
A Low Temperature Heat detector featuring both Fixed Temperature and Rate-of-Rise for use in areas normally below 50°C, where rapid ambient temperature changes are unlikely to occur. The 5151RAUS replaces the 51A51 detector.
Model 5151HAUS:
A High Temperature Heat detector featuring Fixed Temperature operation for use in areas normally below 80°C, where rapid ambient temperature changes may occur. The 5151HAUS replaces the 51D51 detector.
Model 5151RHAUS:
A High Temperature Heat detector featuring both Fixed Temperature and Rate-of-Rise for use in areas normally below 80°C, where rapid ambient temperature changes are unlikely to occur. The 5151RHAUS replaces the 51C51 detector.
