Which sub group of fire detection in the CSI master format covers Zoned (DC Loop) Fire-Alarm Systems?

The subgroup of fire detection systems in the CSI (Construction Specifications Institute) master format that specifically covers Zoned (DC Loop) Fire-Alarm Systems is 28 31 12. This classification indicates that the focus is on the specific types and specifications of fire alarm systems that utilize zoned approaches with direct current loops for their operational setup.

Zoned fire-alarm systems allow for the integration of multiple detectors and notification appliances, enabling specific areas to be monitored and controlled collectively through zoning. This enhances the system’s ability to provide targeted alerts based on the detection of fire or smoke, improving overall safety and response measures.

In contrast, other options correspond to different subcategories in the master format. Understanding these classifications is essential for proper documentation and system design within construction management, especially concerning fire alarm installations.
