Which function checks the lamp will strike correctly on power failure?

• A. Provide a facility for normal power to be restored
• B. The lamp’s battery is sufficient to run the lamp for the rated duration
• C. Simulation of failure for set periods of time eg 1H. 2h
• D. Method of checking lamp will strike correctly on power failure

Answer: (D)

The key idea is verifying automatic activation of the emergency lamp when power fails. To ensure reliability, you need a defined test method that triggers a loss of supply and confirms the lamp lights up as it should and stays on for the rated duration. That explicit testing procedure is what this option describes, making it the best fit. The other points relate to keeping normal power available, the battery’s capacity, or a general simulation, but they don’t specify the actual verification method for the failure condition.
