Sinusoidal Current Signal-Based Fire Detection System with Automatic Address Assignment
Round 1
Reviewer 1 Report
Review:
The article "Sinusoidal Current Signal Based Fire Detection System with Automatic Address Assignment" is based on the proposed system model that employs a conventional power line to transmit crucial fire information related to fire address. This work is well done but can be considered for potential publications after the following minor changes:
1. Kindly rephrase the sentences like "In this paper, a novel sinusoidal current signal-based fire detection system with automatic address assignment" does not make sense.
2. What precautions will be considered in case of an aliasing effect? Explain briefly.
3. Re-check equation 3, will the limit go from 0-N or 0-k as it's till the Kth time slot?
4. What about the cost of the proposed scheme?
5. Please add some recent ref. as only 1 article from the current year has been cited. Therefore I recommend adding more recent references and more sensors-related references, like: https://doi.org/10.1111/cote.12574, https://doi.org/10.1111/cote.12581 and so on.

Comment 1:
Kindly rephrase the sentences like "In this paper, a novel sinusoidal current signal-based fire detection system with automatic address assignment" does not make sense.
Response to Comment 1:
Suggested correction has been made.
Comment 2:
What precautions will be considered in case of an aliasing effect? Explain briefly.
Response to Comment 2:
Thank for the reviewer’s comment. The precaution of aliasing effect is not considered in the paper. However, aliasing matter when reconstructing the original sinusoidal signal from its sampling. We assume that Nyquist condition [1] is applied to FFT in Section 2.1 (paragraph 5).

Comment 3:
Re-check equation 3, will the limit go from 0-N or 0-k as it's till the Kth time slot?
Response to Comment 3:
Thank for your checking for equation 3. The expression is mistakenly written in previous manuscript. We revised the equation and notation for describing equation 3. Suggested correction has been made.
Comment 4:
What about the cost of the proposed scheme?
Response to Comment 4:
Sorry for that part. We didn’t calculate exact cost of the proposed scheme because it is hard to select reference model. One of our contributions is to remove additional communication line. Therefore, we estimate that our model has less cost than conventional fire detection system which require communication line.
Comment 5:
Please add some recent ref. as only 1 article from the current year has been cited. Therefore I recommend adding more recent references and more sensors-related references, like: https://doi.org/10.1111/cote.12574, https://doi.org/10.1111/cote.12581 and so on.
Response to Comment 5:

Reviewer 2 Report
Page 5 - There is plenty of space below the Table 2.
Figure 6., 7., 8. - There is not unit on the vertical axis.
Table 3. - Average values, are they true?
Figure 9. - There is not unit on the vertical axis.
Page 9 - There is plenty of space below the text.
Figure 10. - There is not unit on the vertical axis.
Conclusion - Experimental result should be decribed in more detail. Conslusion is too short.

Response to Comment 1:
Suggested correction has been made in manuscript.
Comment 2:
Table 3. - Average values, are they true?
Response to Comment 2:
The average values are calculated from five iterations. We select the number of iterations based on the experiment because the variance of the results is not much different.
Comment 6:
Figure 6., 7., 8. - There is not unit on the vertical axis.
Figure 9. - There is not unit on the vertical axis.
Figure 10. - There is not unit on the vertical axis.
Response to Comment 6:
Thank for checking no unit for vertical axis. The output voltage/current signals have [V]/[A] units and amplitude of FFT is normalized as 1. Suggested correction has been made in Section 3.
Comment 7:
Conclusion - Experimental result should be decribed in more detail. Conslusion is too short.
Response to Comment 7:
Suggested correction has been made in manuscript.

Reviewer 2 Report
Nearly all my comments and suggestions were done, but I still do not understand Table 3. I do not understand the average value. If I will choose first row, you have there 5 iteations. You calculated the average value of 15.05 Hz, but I calculated the value of 15.02 Hz from the same 5 iteration (15.04 Hz, 15.00 Hz, 15.04 Hz, 15.03 Hz and 14.98 Hz).

Response to Comment 1:
Sorry for calculating average value of frequency, which is mistakenly written in the Table 3. According to reviewer’s check, suggested correction has been made in manuscript.
