Arming Laser-1

  1. When entering Laser-1, there should be an audible chime and a flashing LED on the chime. The chime is on the west wall of the Laser-1 airlock.

  2. Attempt to arm all the local interlock modules before arming Laser-1. The Dira will not arm.

  3. Arm the Laser-1 room control interlock module. Laser-1 room interlock module has LED on for ROOM ARMED.

  4. All local interlock modules have LEDs on for LOCAL CONTACTS DISARMED.

    • Dira

    • AUX 1

    • AUX 2

    • AUX 3

    • AUX 4

  5. VIEWMARQ displays show DANGER LASER ON.

    • Laser-1 entrance.

    • Laser-1 airlock.

  6. Dira LASER ENCLOSURE INTERLOCK protocase laser warning module shows DANGER LASER ON.

  7. Dira LASER ENCLOSURE INTERLOCK protocase CONTROL CONTACTS AUX #1 and #2 should be auto-armed from arming Laser-1. They cannot be disarmed.

  8. Laser warning module displays DANGER LASER ON.

  9. Entry keypad has LED on for INTERLOCKED.

  10. Laser control module displays DANGER LASER ON.

  11. The push to exit button is on.

  12. The airlock / corridor door is magnetically locked.

  13. Use the push to exit button to leave Laser-1.

  14. Use a random pin on the entry keypad module and scan your badge. The door should remain locked.

  15. Use the correct pin and scan your badge. Hold the door open for x seconds and allow the interlock system to trip. The system should return to a completely disarmed state.

Arming the Dira

  1. Arm the Dira local interlock module. Dira local interlock module has LED on for LOCAL CONTACTS ARMED.

  2. The VIEWMARQ display in Laser-1 airlock DANGER LASER ON - IR EYE PROTECTION REQUIRED.

  3. The VIEWMARQ display in the Laser-1 entrance shows DANGER LASER ON - IR HAZARD.

  4. The VIEWMARQ display in Vault-1 Control shows LASER SAFE - DIRA ARMED.

  5. The Vault-1 beacon stacks should show green and white LEDs on.

    • Vault-1 control.

    • Vault-1 east wall.

    • Dira LASER ENCLOSURE INTERLOCK protocase.

  6. Beacon stack on the Pharos LASER ENCLOSURE INTERLOCK protocase will only have a green LED on.

  7. Dira LASER ENCLOSURE INTERLOCK protocase laser warning module shows DANGER LASER ON.

Safe Dira E-Stop Test

  1. Put the Dira into a powered down state.

  2. Arm Laser-1 and the Dira.

  3. Press one of the Dira enclosure laser e-stops.

  4. Verify that the Dira power supply is cut off.

RF-1 Door

  1. With the Dira not armed, open the door between RF-1 and Laser-1. The door monitor module should display nothing.

Crashing the Dira

  1. Once every 6 months, the Dira laser emergency stop buttons are testing that they can successfully cut power to the Dira from a fully armed state. Verify if the last testing date was 6 months ago.

  2. If 6 months have passed, arm the Dira laser and use one of the Dira laser e-stops to cut power from the Dira in an armed state.
