Part of Vault/Secure Room Standards - IDS/ACS Power Supply
Associated with IA controls: PESS-1, PEPF-2
Failure to meet standards for ensuring that there is an adequate commercial and back-up power sources for IDS/ACS with uninterrupted failover to emergency power could result in a malfunctionof the physical alarm and access control system. This could result in the undetected breach of classified open storage / secure rooms or vaults containing SIPRNet assets and undetected loss or compromise of classified material.
Primary Power Checks: Check #1. Check to ensure primary power for all Intrusion Detection System (IDS) equipment and Access Control system (ACS) equipment is either commercial AC or DC power. Check #2. Check to ensure that in the event of commercial power failure at either the secure room/area or monitor station, the equipment changes power sources without causing an intrusion alarm indication. An Uninterrupted Power Supply (UPS) will be required for this to ocurr. Emergency (Backup) Power Checks: Check #1. Check to ensure that emergency power consists of a protected independent backup power source that provides a minimum of 8-hours operating battery and/or generator power. When batteries are used for emergency power, they shall be maintained at full charge by automatic charging circuits. The manufacturer's periodic maintenance schedule shall be followed and results documented. Check #2. Power Source and Failure Indication: Check to ensure that an illuminated indication exists at the Power Control Unit (PCU) of the power source in use (AC or DC). Check #3. Check to ensure equipment at the IDS/ACS monitor station indicates a failure in power source, a change in power source, and the location of the failure or change. 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.
Fixes - Primary Power: Fix #1. Ensure primary power for all Intrusion Detection System (IDS) equipment and Access Control system (ACS) equipment is either commercial AC or DC power. Fix #2. Ensure that in the event of commercial power failure at either the secure room/area or monitor station, the equipment changes power sources without causing an intrusion alarm indication. An Uninterrupted Power Supply (UPS) will be required for this to ocurr. Fixes - Emergency (Backup) Power: Fix #1. Ensure that emergency power consists of a protected independent backup power source that provides a minimum of 8-hours operating battery and/or generator power. When batteries are used for emergency power, they shall be maintained at full charge by automatic charging circuits. The manufacturer's periodic maintenance schedule shall be followed and results documented. Fix #2. Power Source and Failure Indication: Ensure that an illuminated indication exists at the Power Control Unit (PCU) of the power source in use (AC or DC). Fix #3. Ensure equipment at the IDS/ACS monitor station indicates a failure in power source, a change in power source, and the location of the failure or change.
