IPS LOCATION & CLASSIFICATION Isolated
Power System Locations:
These systems can be found in a number or areas throughout a hospital or
surgical center: Operating Rooms, Cath Labs, Urology, Labor &
Delivery, ICU/CCU, Emergency Rooms, Radiology, Special Procedures. They supply 120 volts to receptacles as well as 208, 240 and 480 volts
(single and three-phase) to X-Ray and Laser receptacles. The IPS panels
may be located inside the room they serve or they may outside the room in a
corridor, in a central location in a corridor, or in an electrical closet in the
vicinity. When an IPS panel is located outside the room it feeds, a remote
alarm unit will be installed inside the room to provide audible and visual
indication of a problem. Isolated Power System Classification: For the purpose of establishing the importance of these systems and to identify the level of care IPS systems should receive in terms of periodic testing and inspection, please consider the following: Isolated Power Systems are located in the: "Critical Branch" under the "Emergency System" of the "Essential Electrical System (EES)" and - to use JCAHO language... Isolated Power Systems are critical operating components of the "Utility System" which must be inventoried, tested and documented according to JCAHO Environment of Care - EC.2.14. When one considers the placement of these systems in the hospital's electrical distribution system, the loads they supply (life support equipment) and the risk mitigation they offer, it is easy to see how critical these systems are. Further, NFPA 99 Section 3 acknowledges the criticality of these systems by requiring testing every (6) months for systems with analog LIMs, and every (12) months for systems with digital automated LIMs. |
