A. Emergency Generator

1. Due to the possibility of a failure of electrical service from Xcel Energy, Independence Plaza is equipped with an emergency generator, which starts automatically in the event of a power failure.
2. In the event of a power failure, the emergency generator will supply electrical power to the following areas within the building:
   • Emergency lighting system
   • Stairwells
   • Exit lights
   • Corridors - spot lighting
   • Tenant suites - spot lighting
   • Parking areas - spot lighting
   • Fire alarm system
   • One elevator in the low-rise and one elevator in the high-rise elevator core
   • Fire pump
   • Supply and return air fans
   • Garage exhaust fans
   • Sump pumps
   • Air compressor

B. Power Failure Procedures

1. The emergency generator will start automatically and supply emergency power to the above-mentioned systems within 10 seconds.
2. All elevators will stop and then return to the first floor, one at a time, where the doors will open and allow passengers to exit. Once all elevators have returned to the lobby, one elevator in the low-rise and one in the high-rise elevator cores will then operate in a normal capacity on emergency power.
3. The emergency lighting system will turn on within 15 seconds of a power failure. The emergency lighting system will provide light in the office areas, corridors, and stairwells to enable people to see where they are going.
4. Should the emergency generator fail to start, tenants should relocate to the perimeter of the building and wait for further instructions.
