A bump test can be bypassed and the system will still operate. True or False?

• A. TRUE
• B. FALSE
• C. Depends on model
• D. Not applicable

Answer: (B)

A bump test verifies that sensors respond to a known stimulus and that the alarm/interlock logic operates correctly. Its purpose is to confirm the detection capability remains within spec and that alarms will trigger when a real hazard is present. If you bypass this test, you might think the system is ready, but hidden faults—degraded sensitivity, calibration drift, or a failed sensor—can go undetected. In real operation, those faults could prevent detection or delay alarms, compromising safety. So, the statement is false: you cannot bypass a bump test and still rely on the system to operate safely and reliably.
