23、 of an existing non-addressable fire alarm system. 3. A non-addressable fire alarm system as an extension of an existing non-addressable fire alarm system. The following section addresses each scenario. Modify specification accordingly for this project. A. A /fully addressable fire alarm system/ /fu

24、lly addressable fire alarm system as an extension of an existing non-addressable fire alarm system/ /non-addressable fire alarm system as an extension of an existing non-addressable fire alarm system / shall be designed and installed in accordance with the specifications and drawings.
