Interior and exterior surfaces will be gel-coated to color choice of customer. Gel-coat thickness to be no less than 15 mils (0.38mm). Foam core will be class II and have a density of no less than 2.5lb/cubic ft (0.032kg/m3). Resin shall be fire retardant and meet ASTM E-84 fire rating. Wall thickness will be a minimum of 3 inches (76mm).

FLOOR: Floor will be a wood/foam/wood 1-1/8 inch (28mm) plywood top, urethane foam insulation, 3/4 inch (19mm) plywood sandwich construction. Bottom face will be fiberglass for weather resistance to a thickness of not less than 1/16 inch (1.6mm) Floor thickness will be no less than 3 inches (76mm). Wood blocking, 2 inch by 4 inch (51mm by 102mm) will be used as needed. Interior floor finish will be gel-coated fiberglass, with non-skid applied. Shelter will be attached to floor by bolts spaced as needed to meet design loads of shelter. Outside FRP shelter shell will cover edge of floor assembly and be totally sealed for weather penetration.

SKID ASSEMBLY: Assembly consists of two longitudinal beams with lateral floor supports as needed. Skid assembly will be bolted to floor. Assembly will extend beyond shelter walls to provide pick-up points. All steel will be hot-dipped galvanized as per ASTM A-123.

FRAME DOOR AND HARDWARE: Frame for door will be molded as part of shelter shell. Door will be same sandwich construction as shelter. Neoprene gasket will provide continuous seal of door to frame. All hardware will be as specified, which includes three hinges per door and a freezer style door latch.

SHELTER R VALUES:

• Wall = R-26
• Roof = R-36
• Floor = R-26

SHELTER LOADS: Shelter construction will meet listed loads:

• Wind load - 125 mph (200kph)
• Snow load - 300# PSF (490kg/m2)
• Live floor load - 300# PSF (1470 kg/m2)
UBC Seismic - Zone 4
Exposure - “D”
Bulletproof per UL

ISPI FIRE SUPPRESSION SYSTEM SPECIFICATIONS

GENERAL DESCRIPTION: The Fire Suppression System will be a Kidde ECS Series FM-200 System (or equal). The corresponding Control/Releasing equipment will consist of a Kidde Suppression Panel. A Special Hazards NICET level III certified designer will design system.

AGENT: FM-200 (Heptafluoropropane) will be designed for a 7% concentration. Full discharge will be achieved within 10 seconds.

AGENT STORAGE CYLINDER: The cylinder will be equipped with a pressure safety release. Cylinder will be floor mounted with the manufacturer’s standard heavy-duty cylinder clamp.

DISTRIBUTION PIPING A-53 or A-106 Seamless pipe Grade A or B will be used. Fittings are to 300lb (136kg) Class. After assembly the pipe will be cleaned and painted with Red Enamel.

SUPPRESSION CONTROL PANEL: Will be mounted in a NEMA Type 1 enclosure. The enclosure will be sized to accommodate power supply, common control board, suppression control board, amp/volt meter, digital countdown display and auxiliary relay board.

MANUAL STATION: Will be dual action single pole single throw switch.

ABORT STATION: Will be the dead man type.

IONIZATION DETECTOR: Will be a dual chamber type designed to sense both visible and invisible products of combustion. Design will allow for a 360 degree smoke entry, listed for air velocities up to 2000 FPM (10 m/s). Detector sensitivity will be tested prior to acceptance using a Fenwal ST-001 meter.

PHOTOELECTRIC: Will respond to both flaming and smoldering conditions. Design will allow for a 360 degree smoke entry, listed for air velocities up to 4000 FPM (20m/s). Detector sensitivity will be tested prior to acceptance using a Fenwal ST-001 meter.

SYSTEM CONFIGURATION: The detection initiating circuits will be programmed to cross-zone detection principle. An alarm condition from either detection circuit will activate the alarm bell. An alarm condition from either detection circuits or manual pull circuit will activate the horn/strobe pulsing (bell goes silent), discharge time delay and HVAC system shutdown (Programmed for 60 seconds). Activation of the abort station will freeze the discharge countdown to 10 seconds. Release of the abort station will resume the discharge countdown. Upon discharge the horn/strobe will go steady.

All of the integrated sub components (HVAC, fire suppression, access control/security, AC & DC power) can be monitored and controlled utilizing a custom supervisory control and data acquisition (SCADA) system located in an ISPI SHELTER.


ISPI MODULE AC POWER SYSTEM SPECIFICATIONS

GENERAL DESCRIPTION: The AC power system in ISPI modules will be installed to serve the requirements of (a) the DC plant, (b) air conditioning equipment, (c) the fire protection system and (d) general lighting and receptacles. AC power systems will conform to National Fire Protection Association (NFPA) Standard 70 (National Electrical Code).

POWER SOURCE: AC power will typically be delivered to the module from the local site’s service point. Power will be delivered at the lowest utilization voltage and frequency typical for the local area (for example: 208/120V, 3-phase, 60Hz for US installations). Typically, no transformation of power to a lower voltage is done in ISP shelters. In some cases, site power may be at a higher voltage than the ratings of systems within the module. In these cases, a transformer outside the module will step the voltage down to the utilization level. “Normal” power will generally be delivered from the local utility system. “Standby” power will be delivered from on-site standby generators, provided either by the site owner or by ISP.

SHELTER PANELBOARD: Distribution of AC power to loads within the shelter will be from a small panel board installed in the shelter. Typically, the panel board will be installed in a location near the entry door. The shelter panel board will be in a NEMA Type 1, surface-mount enclosure. Minimum panel requirements are 240V, 100A, 10,000AIC, and 20 circuits.

WIRING: AC wiring in the modules will use copper conductors, with 600-volt insulation. Wiring will be protected from damage in conduit.

LIGHTING: Inside the modules, lighting will be fluorescent. Minimum lighting consists of a single 4-foot, 4-tube fixture. Modules larger than 10’ x 10’ will have additional fixtures installed as appropriate to provide light at all equipment racks. A motion sensor installed near the entry door will control lights. Motion sensors will automatically turn lights off after personnel leave the shelter to prolong lamp life.

Lighting will be provided at the outside door of the module at sites where it is appropriate. Local practices and/or sitting requirements may make outdoor lighting unnecessary or unwanted. Where installed, outdoor lighting shall use high-pressure sodium fixtures. The fixtures will be controlled by photocell, to turn the light on at dusk and off at dawn.

Emergency lights will be installed inside modules to provide light in case of a power outage.

RECEPTACLES: Duplex receptacles will be installed to provide power for small tools and maintenance test equipment. Sufficient numbers of receptacles will be installed so as to minimize the need for extension cords for test equipment used at any rack location.

GROUNDING: AC system grounding will conform to requirements of both the National Electrical Code and Bellcore standards. The AC power system’s grounding point will be at its source (the local utility or the secondary of the transformer from which the low-voltage power is derived). The panel board’s ground bar will be bonded to the shelter’s steel frame.
