Foreword
This document is in accordance with the provisions of GB/T 1:1-2020 "Guidelines for standardization work Part 1: Structure and drafting rules for standardization documents"
Drafting:
This document replaces GB 4715-2005 "Point-type smoke detectors": Compared with GB 4715-2005, except for structural adjustments and editorial
In addition to the modifications, the main technical changes are as follows:
a) Added the classification of point-type photoelectric smoke detectors (see 4:2);
b) Added terminal requirements (see 5:3:3);
c) Changed the range requirements for the response threshold of point-type photoelectric smoke detectors (see 5:7, 4:2 of the:2005 edition);
d) Deleted the slow developing fire response performance (see 3:8 of the:2005 edition);
e) Change the constant humidity and heat (operation) test to the alternating humidity and heat (operation) test (see 5:12, 4:10 of the:2005 edition);
f) Added requirements for the contamination alarm function of the sensing components of point-type photoelectric smoke detectors (see 5:15);
g) The light source type of the flash device has been changed (see Appendix C, Appendix C of the:2005 edition):
