Asenware AW-D138C Conventional Smoke and Heat Combined Detector

The AW-D138C is a conventional detector that combines smoke and temperature sensing in a single housing; since it is powered with 9~28 VDC via the zone line, it does not require a separate power cable to be run. The optical smoke section operates in the sensitivity range of 0.18~0.3 dB/m, while the heat section has a fixed temperature setpoint of 57°C and with A2R class behavior evaluates both the fixed threshold and rapid temperature rise together. This dual architecture balances the detection decision in rapid flame development where smoke detection alone would be delayed, or in environments where steam and dust can be misleading. The 360° visible red LED indicator allows the alarming detector to be distinguished from any point in the corridor; the device is designed for indoor installation within the temperature range of -10 ~ +50°C and condensation-free humidity range of 5-95 RH. When selecting, attention must be paid to the complete code: AW-D138C-4W for 4-wire relay output applications, while AW-D138 is a separate product code for addressable systems.
