NFPA 72 Section 17.15.6 specifies the installation height for which device?

• A. Manual stations
• B. Heat detectors
• C. Smoke detectors
• D. Control panels

Answer: (A)

The height rule is about accessibility for initiating devices. NFPA 72 Section 17.15.6 sets how high manual initiating devices (pull stations) should be mounted so occupants can reach and operate them quickly in an emergency. These devices are designed for immediate human activation, so the installation height is chosen to be easily reachable by most people, without climbing or bending to dangerous levels, while still avoiding inadvertent activation. Detectors and control panels serve different purposes and have different mounting considerations: detectors (like heat or smoke) are installed where they can sense conditions effectively, typically high on walls or ceilings, and control panels are placed for maintenance and readability by personnel. Therefore, the section focuses on manual stations because their primary function—prompt, deliberate activation by occupants—drives the specific mounting height requirements.
