Field notes
- Confirm whether the condition is local or received over NOTI-FIRE-NET.
- Record the exact point/zone/event before reset or replacement.
- Use model-specific documentation for programming and compatibility.
Use the exact generation. Similar model names can have different hardware, firmware, menus, programming tools, device support, and service procedures.
