The purpose of this procedure is to validate the functionality of the Vault-1 and Hutch-1 Narda Smarts II Microwave Sensor.

Starting Conditions

  1. Narda meters are not alarming.

  2. All meters are calibrated.

    • Vault-1

    • RF-1

  3. Vault-1 Control IONIZING RADIATION INTERLOCK protocase MICROWAVE AREA MONITOR lamp is green.

  4. Narda relay contact #10 in Vault-1 Control West aggregator panel LEDs are all on.

  5. Yellow and blue contact blocks in Vault-1 Control west aggregator panel have continuity to each other.
