Where should an initiating device not be installed?

• A. In a locked cabinet
• B. In an inaccessible location
• C. Near a doorway
• D. In a clean, dry area

Answer: (B)

Initiating devices must be accessible for testing, maintenance, and to verify operation after installation. If one is placed in an inaccessible location, authorized technicians can’t reach it to test or service it, faults may go undetected, and the system’s reliability suffers. That’s why you should avoid locations that are hard to reach or locked away. Places near a doorway or in a clean, dry area are typical and appropriate because they keep the device accessible while still protecting it from dust, moisture, and tampering. In short, the goal is to ensure easy access for testing and service; an inaccessible location defeats that purpose.
