Answer :
Final answer:
To test a fixed temperature non-restorable line type heat detector, the appropriate tool is a calibrated device, as it accurately measures temperature response. Other options do not fulfill the specific needs of testing heat detectors. Utilizing the correct device is crucial for safety and effective operation testing.
Explanation:
Understanding the Testing of Heat Detectors
When testing a fixed temperature non-restorable line type heat detector, it is essential to use the correct tools to ensure accurate measurement of the heat detector’s functionality. Among the options provided, the appropriate tool to use is a calibrated device. This is because a calibrated device can accurately measure and verify the temperature at which the detector is designed to activate.
Using a heat gun (A) may supply heat, but it does not measure the detector's response accurately as it might exceed the detector's limits. An ohmmeter (B) is used for measuring electrical resistance, which might not provide relevant information for a heat detector's thermal response. A voltmeter (D) measures electrical potential difference, which also does not pertain to thermal activation in this scenario.
Conclusion
In summary, to effectively test a fixed temperature non-restorable line type heat detector, a calibrated device should be utilized to ensure proper functionality and safety.
