An existing fire alarm system is being extended to another part of a building. What rehabilitation work category applies?

When extending an existing fire alarm system to another part of a building, the appropriate category for this work is modification. The reason for this classification is that modification involves changes to the existing system, including enhancements or expansions that can improve its capabilities or coverage.

In this case, adding new components or connections to the fire alarm system to encompass a larger area fits within the scope of modification, which may include alterations such as integrating new devices or updating connections to ensure compliance with current regulations and standards. This differs from an addition, which might imply creating an entirely new system; modification indicates that the foundational system is being adapted or altered while maintaining its original framework.

Repair refers to fixing existing components, renovation implies significant upgrades or changes beyond mere expansion, and these do not accurately describe the act of extending and improving the functionality of the current fire alarm system. Therefore, modification is the proper terminology to define this kind of work on the fire alarm system.
