Fire department connections are actually used in fire sprinkler systems.When any fire occurs water is discharged from the sprinkler heads that have fused, and are discharging water to supress and extinguish the fire. The fire department connection is used by the fire department to add to the water supply to the sprinklers and/or charge the interior hydrant connection withn the building (if any).

Fire departments nowadays are asked to do many more things then they were in the past. Firefighters today are expected to be able to take care or medical calls, Car accidents,… Haz-mat, Decon, Rescues such as high angle and low angle rope rescue water rescue ice rescue confined space rescue, they are also expected to put out not only house fires but car fire, plane fires, brush fire and forest fires. Also when a person goes missing fire departments come to assist with tools such as thermal imaging cameras. not to mention they are expected to do so many community service hours on fire prevention.
The FDC and hydrant aren't something that connect directly together. In order to put any kind of water pressure into a sprinkler system, an engine HAS to pump it in. Therefore…, as long as the fire apparatus has enough hose, or can GET the hose from other apparatus the hydrant could hypothetically be a block away. There may be problems with friction loss with any large distances though. In my local area, the fire department has a maximum of 150 feet from the FDC to the Fire hydrant.
There is a suction line on every apparatus with a pump. Theengineer, who drives the rig, connects this line to the hydrant andto the pump suction. Some equipment has this line… pre-connected tothe pump inlet. In many fire hydrant systems there is enough pressure to fill andpressurize an ordinary hose (of large diameter) running from thehydrant to the pumper truck's inlet. That way, there is very little"suction" required in the pump, since the water is already beingdelivered with some amount of pressure. If it is "dry hydrant" with no pressure, then suction is required. Edit: Typically it is a Firefighter that 'snubs' the hydrant, notthe Engineer. It is the Engineer's job to 'Position' the apparatusbefore transferring the engine into 'Pump' (typically, once theapparatus engine is transferred to 'Pump', it is stationarythroughout the incident). There are different options for water'Intake', they can be long leads whereby a supply line can be asmaller diameter (2 1/2") or a 'Short Sleeve' (4") direct to pumpdiameter where the Pumper is 'Positioned' close to the hydrantsnubbed. There are also situational logistics which require twoPumpers (or more) to 'Relay' a supply line due to the fact that thetotal amount of hose on a given Pumper is less then the distancefrom the fire to the hydrant. It is the Engineer's job to figureout what pressure is incoming from the supply line and the amountof nozzle pressure required for firefighting at the nozzle. Thisdetermines what pressure you need to be pumping at. This pumpingpressure must take into consideration elevation, friction loss ofpressure in the amount of hose laid out, etc. It can be a life ordeath calculation for the Firefighter at the nozzle's fighting endwhich could very well be 40 stories above the Engineer manning thepump.
What feature is required on a fire department connection that allows a firefighter to charge the first hoseline prior to connecting the second?
A gated Y valve.
it will depend on what terms you were fired on.
Yes it is. It is connected to the Department of the Treasury. As is the Secret Service, by the way.

What is the NFPA definition of what is the maximum distance a fire department connection can be from a fire hydrant?
36" W x 36" D x 78" H

In the past the FDC was optional. NFPA 13: Standard for the Installation of Sprinkler Systems now requires the connection except for systems of 20 sprinkler heads or less, or …when permission has been obtained from the authority having jurisdiction. Sources- Brannigan & Corbett- Building Construction for the Fire Service (4th Ed) 2008. The above is a direct quote on page 288 if you so need it for a paper. So when you have more than 20 sprinkler heads, or when you have obtained permission. Doug E.
Normally in the front of the building.
Police departments usually assist with traffic control at vehicle accidents and fires. Police are also usually called to assist with unruly patients. Some agencies a…lso have police officers respond to medical emergencies to assist medical responders. Departments that do this usually require their police officers to take additional First Responder or Emergency Medical Technician classes.
It is not necessary you can also use gate valve.
Yes, parking is allowed unless otherwise indicated on another sign, or as required by local ordinances (e.g., no parking within 10 feet of any hydrant or FDC). For example, "N…O parking in Fire Lane" would generally include no parking where the FDC is located adjacent to the fire lane.
