Examples are offices, labs, patient rooms, treatment rooms, exam rooms, work rooms, nurse stations,
and conference rooms.
xiii. Signage and Art Lighting: Utilize low voltage track lighting by Halo or Capris with MR3516 lamps.
These fixtures shall be controlled separately with a dimmer. Track and heads shall be selected by the
Design Professional to compliment the surrounding architecture.

26 60 00 Emergency Power


  1. General
    a. All emergency power system work shall be reviewed with Maintenance and Engineering (319- 356 -
    2582).
    b. Existing loading of the generator and each emergency branch shall be obtained and figured with the proposed
    new loads in sizing calculations.
    c. Emergency power distribution shall be segregated into Life Safety branch, Critical branch, and Equipment
    branch. The Equipment branch may have separate transfer switches for automatic and non-automatic
    transfers. Lighting equipment and devices shall be placed on the different branches according to NEC 517.
    d. In general, the Life Safety branch serves exit lighting, emergency path of egress lighting, alarm systems,
    communications systems, lighting at the generator location, elevator cab and control equipment (not the
    motor), and automatic doors. The Critical branch serves task illumination, equipment, and power
    receptacles in critical care areas, patient care areas, and additional areas needed for effective hospital
    operation. The Equipment branch (delayed automatic) serves equipment such as central suction systems,
    sump pumps, compress air systems, smoke control systems, and kitchen hood exhaust. The Equipment
    branch (delayed automatic or non- automatic) serves heating equipment for critical care or patient care areas,
    jockey pump, elevators, and HVAC in some critical care areas. Refer to NEC 517 for complete list and
    discuss with Owner’s Rep. and Maintenance and Engineering any other items that need to be put on one of
    the emergency power branches.
    e. Where it is determined that a department in the facility needs emergency power back- up for safe operation
    during a power outage, separate transfer switch(es) shall be installed specifically for this department. An
    example of this is in the Radiology Department in Colloton Pavilion.
    f. Sprinkler system fire pumps shall have their own transfer switch. The normal source shall come from the
    main electrical service panel and the main generator distribution switchboard. Refer to NEC 695 and 700.
    g. Each bank of elevators shall be served from a separate transfer switch and a separate elevator distribution
    panel. Upon a loss of power, the elevators shall return to the designated floor and stop. One elevator shall
    remain operational for emergency use.
    h. An emergency power generator shall feed a generator distribution switchboard. This switchboard is used to
    distribute power to the transfer switches for all the branches of emergency power, fire pumps, and remote
    generator radiator fans. Each branch of emergency power shall have a main distribution panel on the load
    side of the transfer switch for distribution to the separate emergency branch panels located on each floor.
    i. No area of the facility shall be served by 100% normal power or 100% emergency power.
    j. Emergency generators and the main distribution of emergency power shall be at
    277/480 volt power. This power shall be stepped down to 120/208 volt on each floor with local step down
    transformers.
    k. Any new generators shall have their generator distribution switchboard tied together with the two nearest
    separate generator distribution switchboards.
    l. A DNR permit and modeling is required for generators. A DNR permit is required for diesel fuel tanks.
