Fire Suppression Details

Redundant and independent fire systems

3 systems – VESDA, FM200/VORTEX , Pre action Sprinkler System

• Very Early Smoke Detection and Alarm. A sensitive item of equipment connected to a fire alarm system (VESDA - Air sampling smoke detection). In a fire event, ventilation duct systems can convey smoke, hot toxic. gases and flames from one area to another.

• Three stage AQUASONIC Fire Suppression System– Stage 1, one smoke detector, rings alarm– Stage 2, two smoke detectors, strobe alarm and 30 second countdown– Stage 3, gas system discharges– Includes override and reset buttons

• Two stage pre-action sprinkler system– Stage 1: two smoke detectors or one heat detector (135 F), fills water pipes– Stage 2: Heat (155 F) discharges water

• Trouble alerts & alarms bring fire department

• Tampering will alert fire department

• Fire alarm stations for immediate alarms

04/13/23 3

AQUASONIC Fire Suppression System• utilizes non-toxic and readily available extinguishing

media (water and nitrogen)

• FM approved

• Environmentally safe

• Self-contained

• Minimal water discharge

• Effective on Class B fires

• Flexible system piping and atomizer location

04/13/23 4

Life Safety Issues

• Access Control to the site itself– No unsupervised visitors– Prevent unauthorized vehicles from proximity to the building– NOC BOX for Fire Department

• Exterior Lighting should promote safety and discourage crime

• Ease of access for fire fighting equipment– Location of hydrants

• Fire Exits are not impeded by interior storage volumes

• Air quality within the data center

• Fire Wall separation(2 hour Rated) between areas and rated fire doors

• Skylights and emergency lighting

• Cross ties and bracing to avoid shelving collapse

04/13/23 5

Security System aligned with Life Safety

• Access control will be provided using access card, which uses a radio frequency identification device (RFID) chip technology. This RFID technology will be installed throughout SPRINGFIELD DC and zoned for “need to know” access. The access control system is database oriented, which allows for individual information, including zone access, to be displayed in the security office or approved security stations.

• All IDs are pictured.

• All badges do not leave the building. Check in and out feature. IDs are returned to guard. The guard will call operations where the IDs are stored in a zone 4 area.

• Any badge that is taken out of the building will be deactivated automatically either by a time limit or exit.

• Access to Computer Area– Revolving Door for people -equipment traps for Asset control – Equipment traps should be for environment and security – 2 door solution – Doors must be controlled

together so both sets can not be opened at the same time. Second set of doors into secured zone must be opened either from inside secured zoned or remotely at operators or Security station.

• Surveillance Camera – – Infrared/Black & White/Color Overlay – Features including motion activation with pan, zoom and tilt– Interior Motion sensor on and off with energy management monitoring – Exterior On 7x24x365 Weather protected

• Only Computer/Network/Secured Storage Room will default to SECURE (Closed)

• Computer room designed with Fire Exit doors which captures RFID as they exit

Sprinkler Topics

•History

•Types of Sprinkler Systems

•Types of Sprinkler Heads

04/13/23 7

History of Fire Sprinklers

•Officially developed and used by Henry Parmalee in 1874 to protect his Piano factory

•Used clay and wood pipes with holes drilled in them

•A tank on the roof of the structure was drained during a fire and released the water into the pipes

•Winter was a problem, and making sure someone was watching all the time.

04/13/23 8

Fire Sprinkler Time Line

• 1806- John Carey designs a systems of plungers and perforated pipes

• 1812 – Colonel William Congreve designs perforated pipes and valves

• 1875 – Parmelee invents the modern sprinkler. It consist of shells and soldered brass caps.

• 1882 – Grinnell invents and improved sprinkler that can withstand higher pressures and distributes water more evenly

• 1896 – N.F.P.A is formed and publishes codes for automatic sprinkler installation

04/13/23 9

Types of Sprinkler Systems

•Wet Sprinkler System

•Dry Sprinkler System

•Deluge Sprinkler System

•Pre-Action Sprinkler

04/13/23 10

Parts of a Sprinkler System

•OS&Y – Outside Stem & Yoke

•PIV – Post Indicator Valve

•Main Control Valve – Controls the water for the whole system

•Main Drain – Drains system

• Inspector Test – Tests systems

•Alarms – Water flow and Air Alarms

04/13/23 11

Components of Sprinkler System

• Underground brings water from the City Mains to your building

• Water is sent through a backflow

• All systems usually require an FDC or Fire Department Connection to increase the water pressure during a fire

• Enters either the fire pump where it is pumped to a certain pressure or is released into the riser

• Risers (rise) vertically through the floors to feed the branch lines

• Branch lines extend off the Risers and Mains horizontally to bring water to all the sprinkler heads

Wet System

• Water is in branch lines and at the sprinkler heads at all times

• Wet Systems cannot be in areas that may freeze

• Water pressure must be maintained at all times

• Water Pumps are put in place to keep water pressure at a certain PSI

• There is no delay in time that water is put on the fire

• Require the least amount of maintenance

04/13/23 14

Dry Sprinkler System

• Require Air Pressure instead of water in the Branch Lines

• The Air Pressure holds down a Clapper Valve, so that water can not be introduced into the system, unless the air pressure is lost

• Used in areas that may freeze

• An air compressor keeps a constant pressure in the system

• When a Fire releases a sprinkler head, the air is released from the piping, and stops holding down the valve that was holding the water back, and water is released

04/13/23 15

Deluge - Not used at SDC

•Deluge Valves are used in special areas

•Sprinkler heads are open at all times

•Used in High Hazard areas

•Deluge Valve opens during a smoke or heat detection

•Deluge systems are needed where high velocity suppression is necessary to prevent fire spread

04/13/23 16

Deluge - Picture

04/13/23 17

Pre-Action Sprinkler System

• Same as a Dry System

• Water is held back by an electronically operated valve

• Two things need to happen before water is released

• The detection system must identify that there is a problem with smoke or flame

• Water is then released into the piping

• Secondly the sprinkler heads must be activated and released to put water on the fire.

04/13/23 18

Types of Sprinkler Heads

•Pendants

•Uprights

•Sidewalls

•Special Coverage

04/13/23 19

Fire Sprinkler Colors

•135-170 degrees = Red

•175-225 degrees = Green

•250-300 degrees = Blue

•325-375 degrees = Purple

•400-650 degrees = BLACK

04/13/23 20

Pendant Head

•Most common head

•Extends down from a ceiling

•Sprinkler sprays a stream downward onto a deflector

04/13/23 21

Upright Head

•Sits on top of the piping

•Sprays water up towards the deflector

•Can not be used as a pendant

04/13/23 22

Sidewall Heads

•Comes out of a wall to protect hallways or small rooms

•Has a fan shaped deflector

•Used in Hallways or special areas that are not big enough for regular heads

04/13/23 23

Special Heads

•Sprinkler heads have been designed to protect everything from attics to window openings

•Attic head have special bends in them to throw water at certain angles

•Coatings for corrosive areas and heads to match décor of room even exist

•Dry Pendants are used to protect areas that freeze on wet systems

04/13/23 24

Types of Sprinkler Systems

•Residential-Just beginning to become popular– Piping is made of a special CPVC plastic

• Industrial-Heavy amounts of fire load require many heads.– Piping is usually made of metal
