Users of emergency power will notice a series of sequential blinks at the beginning of the East Tower test (one per electrical zone) as each of the 14 emergency power switches are engaged. At the end of the test, all areas will blink (yellow) as the switches
return their respective areas to normal power.</li><li style="font-family: "Palatino Linotype", "Book Antiqua", Palatino, serif; font-size: 12pt; color: rgb(0, 0, 0); align-self: center; margin: 0in 0in 0in 0.5in;">

The test, although intended to simulate an actual power outage, has been modified to keep the disruption to Hospital services at a minimum. If an actual power outage occurs, the electrical circuits supported by the generator will be without power for 5 to
10 seconds except for those areas which have their own uninterruptible power supplies. Our recent experience suggests that a real power outage can be expected once a year. If you have equipment, processes, etc. that cannot cope with a power outage of this
duration, your department should consider installing uninterruptible power supplies (UPS's).</div>
