Which device would alert if a box is tampered with?

• A. PIR
• B. BMS
• C. SMPS
• D. Tamper Junction Box

Answer: (D)

Detecting tampering requires a device built to sense when an enclosure is opened or its seal is broken. A tamper junction box includes tamper sensors or switches wired to an alert system, so any opening or interference triggers an alert to security monitoring. The other devices aren’t designed for this specific purpose: a PIR detects motion, not enclosure tampering; a BMS is a general building monitoring system that may include tamper sensors but isn’t specifically the tamper-alert device for a box; and a SMPS is just a power supply. Therefore, the tamper junction box is the appropriate choice for an alert when a box is tampered with.
