Defect Trends in Fire Alarm Systems: A Basis for Risk-Based Inspection (RBI) Approaches

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

This study suggested introducing the RBI methodology of the fire alarm system and suggested process improvement through statistical methods, that is surveys. In conclusion, it was classified into three groups according to the defect category, but it is judged that there is a lack of part on how to improve the system. As the most fundamental question, it isn't easy to know the study's originality. The part of what needs to be improved and the solution to the problems presented have not been presented. In addition, it seems better to submit the presented research results as a journal in the field of policy research in the direction of improving the system rather than engineering improvements.

Reviewer 3 Report

Comments and Suggestions for Authors

The paper was performed to investigate and develop the risk-based inspection concepts on fire alarm systems. The paper presented the analysis results shown in graphical forms to find out the flaw of fire alarm systems.  

 

In abstract, there are many ambiguous words such as lessons, results, findings, and implications. I would like to recommend to authors to wright down much more practical differences from your study methodologies. You can mention the importance of the cable and wire system, the needs of acoustic signal devices, detector contamination effect and so on.

In Figure 1, the Without Defects line should be changed into bar-chart because of it is not necessary to figure out the high and low between them. It is just simple results on the faulty of fire alarm system.

In page 5, line 194, the equation no is missing. Also, you need to notice us why did you select 5% tolerated error for this specific periods in your sample.

Conclusions should be made in accordance with a discussion in section 4. It needs to be summarized by age, system size, and environmental conditions. Conclusions will be well summarized if it is supported by the statistical frequency data analyzed.

Comments on the Quality of English Language

It is not a major problem.

Reviewer 4 Report

Comments and Suggestions for Authors

The manuscript summarizes the results of the evaluation of the reliability of fire alarm systems. The article is well written and well structured, and it correctly describes the data employed and the methodology followed to analyze it

However, I consider this manuscript a report and not a research article.

Round 2

Reviewer 1 Report

Comments and Suggestions for Authors

Thank you for revising many parts through Revision. However, I think some additional modifications are needed because the novelty of manuscript is not well shown.

1) Title: Needs to be written with an emphasis on RBI

2) Abstract: Rewrite required overall, rewrite required to include BACKGROUND, OBJECTIVE, METHODS, RESULTS, and CONCLUSIONS in that part

3) In manuscript SV (sample validation?): I don't understand why you're using this.

4) Introduction or literature review: This needs to be explained by adding references to system age, system size, and environmental conditions. Many references can be found, but there is not enough data to support the results.

5) Introduction: Novelty will be included in the revised manuscript

6) Methods: Please supplement the additional information about the software mentioned in Line 312.

7) Conclusions: The RBI has identified three factors, so the conclusion of the most important risk factors should be added.
