Are there any fire alarm men here??? I know I should read NFPA-72 more in details later, but I thought I should throw the questions here, some of you may give me quick and short answers. Here they are:
- What is the difference between below class of fire alarm wiring and their application?
1. Class A, style D
2. Class A, style Z
3. Class B, style 4
4. Class B, style Y
- Do we have other fire alarm wiring class besides what listed above? Thanks!
