What is the second step in the CCM disarming procedure?

• A. Remove safety PIN
• B. Move the slide arming lever to the DISARMED position
• C. Insert safety PIN
• D. Visually check that designated doors are DISARMED.

Answer: (A)

Safety pins serve as a safeguard to prevent accidental arming or disarming. In the CCM disarming sequence, removing the pin is the action that will unlock the mechanism and allow the disarming steps to proceed. After this pin is removed, the next actions—moving the slide arming lever to the DISARMED position and then visually confirming the doors are DISARMED—can be carried out safely and in the correct order. Keeping the pin in place would maintain a locked safeguard and block the disarming flow, so removing it as the second step is the proper progression.
