A. Emergency Generator
- 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.
- 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
- The emergency generator will start automatically and supply emergency power to the above-mentioned systems within 10 seconds.
- 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.
- 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.
- Should the emergency generator fail to start, tenants should relocate to the perimeter of the building and wait for further instructions.
