At least one manual activation device shall be located a minimum of _____ and a maximum of ____ from the protected hood exhaust system (s) within a path of egress or at an alternative location acceptable to the AHJ.

• A. 2 m - 5 m
• B. 1 m - 3 m
• C. 3 m - 6 m
• D. 4 m - 8 m

Answer: (C)

The key is where the manual activation device (MAD) for the kitchen hood fire suppression system should be placed. It must be located a minimum of 3 meters and a maximum of 6 meters from the protected hood exhaust, and it should be along the path of egress or at an alternative location approved by the AHJ. This range is chosen to ensure the device is easily reachable by someone evacuating, so the system can be activated quickly, while also keeping the MAD far enough from the hood to avoid heat, steam, or accidental activation hazards. Being on the egress path helps occupants reach it without entering the hazard area, and the AHJ-approved alternative location gives flexibility when standard placement is impractical.
