To perform a Search and Secure, complete the following steps:
| Check the Area |
Check for people around the area of search box 1. When you are certain no one is present, press the button on box 1. If the station has multiple search boxes, proceed to search box 2, and so on. An amber light flashing on each box in succession will indicate that you are following the proper order. During this process, a voice warning and a red strobe light will indicate that a search is in progress. |
| Close the Door |
After buttons on all boxes have been pressed and the station has been thoroughly checked for people, exit the station. Close the door(s) by pushing the DOOR CLOSE button until the the green closed LED indicator is lit. The DOOR CLOSE button can then be released. Watch to make sure that no one enters the station during this time. |
| Confirm |
If a Search and Secure has been correctly performed, a steady green LED STATION SEARCH (OR SECURE) light will be seen on the Station Control Panel. The manual and pneumatic door indicator LEDs will be lit displaying the doors in closed and locked state. |
What if the Search and Secure fails?
Occasionally a Search and Secure will be unsuccessful, perhaps because:
- The door was not closed during the allowed time period.
- An EMERGENCY BEAM STOP button could be depressed.
- The person searching the station could miss one of the search boxes.
- The person searching the station could release the closed button before the station door is closed and locked.
When a Search and Secure fails, the voice warning will state, "Station search invalid."If this happens, the Search and Secure must begin again from the beginning.
