Standards for Components

This revision of ANSI/UL 864 dated May 7, 2020 is issued to incorporate the following changes: – Alternative means utilizing adhesives to provide mechanical securement of parts; 6.1.2, 6.2.1, 9.5 – 9.9, Section 83, Section 92.6 – Building System Information Unit; 3.13A, Sections 54A, 54B, 54C, 96.31, – Class N pathway performance criteria; 3.39A, 56.1.13A, 56.1.14, 56.3.1, 56.4.1 – Aligning UL 864 with new UL 268 requirements for special application smoke detectors; 67.5.2.4 – 67.5.2.7, 96.32

1.1 These requirements cover: a)Discrete electrical control units and accessories for fire alarm systems; b)Electrically- and electronically-operated amplifiers that provide speech communication and distinctive sounds in conjunction with fire protective signaling systems; and c)Commercial stationary and fixed power supplies for fire-protective signaling systems, having input and output ratings of not more than 600 V, direct- and alternating-current, (DC and AC).
