Explain in details about the terms “alarm” and “detector”.
Explanation of Solution
Discussion:
The device which provides a warning signal is known as an alarm and it works with the help of a detector when the minimum acceptable protection level is exceeded. An alarm plays a key role in the security systems of mines, residential buildings, and industries.
Example: Smoke alarms, Heat alarms, and Carbon monoxide alarms (alarms for explosive gases).
A detector is the device which has a sensor in the circuit. Sensor responds to the physical stimulus such as smoke, heat or some explosive gases.
Example: Smoke detectors, Heat detectors, and explosive gas detectors.
An alarm works with the co-ordination of a detector which has a pre-programmed sensor for the minimum acceptable levels of smoke, or heat, and so on, based on the application of an alarm.
Conclusion:
Thus, the terms “alarm” and “detector” are explained.
