## Spare parts shall be the same make and model as the installed items, delivered in their original packaging, and labeled with the system they serve.
## A failed solenoid or a failed detector on a released zone impairs the whole system until it is replaced, and the parts that keep a releasing system in service are the ones a local supply house is least likely to stock. {note}
