Telecommunications Design 10- The desire is that all walls hosting EZ-Path fire rated sleeves shall host the entire bank of sleeves
inside the same wall cavity. This may require special framing accommodations in order to
accomplish. See the typical telecommunications room floor plan detail in the Appendix for an
illustration of these sleeves. - All walls shall be finished and painted from the finished floor to and including decking above with
Sherwin Williams #B49 W2 paint. - All walls shall be lined with plywood. See fire protection engineering requirements below for
additional information.
ENGINEERING REQUIREMENTS:A. Environmental Controls
- Maintain continuous and dedicated environmental control 24 hours per day, 365 days per year.
- Design consultant shall calculate the heat load by using equipment manufacturer’s specifications
for each component. Allow for 50 percent growth. - A thermostat shall be located within the TR and control the TR only.
- Maintain a temperature in the following range: 64 degrees F to 75 degrees F.
- The acceptable relative humidity range should be 30% - 55%.
- Dissipate the heat generated by active devices.
- Temperature shall not increase 10 degrees in 60 minutes.
- Maintain positive pressure with a minimum of one air change per hour.
- If an independent cooling unit is installed, the unit shall be located outside of the TR.
10.When installed air conditioning units in the rooms, provide drip pans, shields and drains for leakage
and condensation.
B. Fire Protection
- Wet sprinklers shall be provided in each TR. Provide a sprinkler zone valve in each room.
a. A single interlock pre-action dry sprinkler system may be necessary if IT equipment value
scheduled for the room necessitates it. Inquire with HCIS prior to the design. - Provide a cage around each sprinkler head.
- The room shall be equipped with appropriate fire detection and alarm sensors.
- All walls inside the TR shall be lined with 4’ x 8’ fire-rated AC-grade or better plywood, 8 feet high
with a minimum thickness of .75”. The “A” side shall be what is exposed with the “C” side facing the
wall. - Plywood shall be treated on all sides with at least two coats of Sherwin Williams #B49 W2 paint on
all sides, leaving a fire-rated stamp visible to meet JCAHO standards. - The plywood shall be continuous, into the corners, and mounted with appropriately rated hardware
and not standard sheetrock screws.
C. Power
- Each TR shall be supplied with both Critical and Normal power.
- Power requirements at the rack(s):
a. UPS Rack(s)
i. Provide one (1) dedicated 120VAC quad receptacle and one (1) dedicated
208VAC circuit on emergency generator power. Depending on the UPS
scheduled for the rack, the 208VAC circuit may require up to 60 amps.
Coordinate this requirement directly with HCIS. Any receptacle shall be mounted
at the rear of the rack and attached rigidly to the cable tray above the vertical
manager. The UPS circuit may require a hardwired circuit that can be provided at
the base of the rack.
