Failure to meet standards for the display of masked alarm sensors at the IDS monitoring station could result in the location with masked or inactive sensors not being properly supervised. This could result in an undetected breach of a secure room perimeter and the undetected loss or compromise of classified material.

Shunting or masking of any secure room IDS internal zone or sensor must be appropriately logged or recorded in the system archive. A shunted or masked internal zone or sensor must be displayed as such at the monitor station throughout the period the condition exists whenever there is a system (IDS) survey of zones or sensors. TACTICAL ENVIRONMENT: This check is applicable where Vaults/Secure Rooms are used to protect classified materials or systems in a tactical environment. The only exception will be for urgent (short term) tactical operations or other contingency situations where fixed facilities and equipment are not yet present or incapable of being used.
