PSA Flight Attendant Exam 2025 Complete Practice Test

After inserting the first testing tool into the smoke detector's SELF-TEST slot, the next step is to insert a second tool into the interrupt slot. This procedure ensures that the smoke detector is properly tested and its functionality is verified from both input points. The use of the two tools simulates different operational conditions, allowing for a thorough check of the detector's performance.

Inserting the second tool into the interrupt slot helps in ensuring that the detector responds accurately, confirming whether it can accurately detect smoke or other particulates. This step is part of a systematic approach to safety checks, which is crucial for ensuring that the safety equipment is operational and reliable for emergencies.

Other responses in this scenario do not align with the correct procedure. Simply stopping testing would not provide the necessary confirmation of the smoke detector's functionality. Waiting for a confirmation is not the immediate next step after the first insertion. Releasing both slots prematurely could disrupt the testing process, leading to incomplete evaluations of the device. Thus, correctly inserting the second tool into the interrupt slot is essential for proper testing of the smoke detector.
