This reportshall list
1) each control and safety device installed in accor-dance with this Standard
(2y name of the manufacturer and model number ofeach control and safety device
(3) operational test performed (see CG-440)
ltems (1) through (3) shall be verified by the signa-ture of an authorized representative of the manufactureron this report. An example of an acceptable data reportform is contained in Nonmandatory Appendix C.
