1. The Captain asks the Proby in Engine 324 about the apparatus with the large diameter hose
parked in quarters behind the Engine. The Proby makes several statements. He was correct in
all but which one? (1.2, 3.3)
a. There are six Satellite apparatus in service throughout the city and only one has pumping
b. The primary purpose of the Satellite unit is to provide the incident commander with a
dependable high volume supply of water
c. The Satellite apparatus carries foam equipment in addition to the large diameter hose
d. When assigned to alarms an Engine will respond with the Satellite, each apparatus will be
staffed with at least two firefighters

1. A

Note: A Satellite Apparatus does not have pumping capabilities


2. From the following list select the correctly listed capabilities of the Satellite Water System.
a. Supply the mini-manifold in close proximity to the building
b. Deliver water through 5” hose over long distances
c. Relay water when supplied by a Fireboat
d. Deliver Hi-Ex foam
e. Flush fuel spills and other chemical spills
f. Use their large caliber deluge stream for demolition
g. Draft water at waterfront operations

2-B, C, D, E, F, G,

1.3 The following is a list of the capabilities of the Satellite Water System:
1.3.1 Supply manifolds placed in close proximity to operation
1.3.2 Deliver water via 5" hose over long distances
1.3.3 Relay water when supplied by a fireboat or other pumpers at hydrants or at draft
1.3.4 Draft water at waterfront operations under suitable conditions
1.3.5 Supply or augment the Jamaica Water Supply System
1.3.6 Use large caliber Satellite Deluge Streams for fire suppression, ventilation, or
1.3.7 Deliver high volume conventional foam streams through Satellite Deluge Guns or
Tower Ladder monitors
1.3.8 Deliver High Expansion Foam
1.3.9 Flood cellar or flush sewers, fuel spills, chemical spills, etc


3. You are a Lieutenant working an S/A tour in Engine 72. Shortly after roll call you are
assigned with the Satellite to a 2nd alarm. The fire is in a vacant 3 story 200x800 waterfront
warehouse. Shortly before you arrive the 3rd alarm is transmitted and an additional Battalion
Chief is requested as a Water Resource Officer. Upon arrival you see heavy fire venting through
the roof. The incident commander contacts you on the handie talkie and orders you to position
the Satellite for use of the apparatus mounted large caliber streams. You would be correct to
perform which action? (2.3, 4.4, 5.3, 5.4, 7.4, 7.6)
a. Order the Satellite chauffeur to position the apparatus close to the building to ensure the
deepest possible stream penetration
b. You directed your ECC to use the drafting site identified on the Pre-incident guide even
though the fireboat is on scene and able to pump to the Satellite
c. In anticipation of connecting multiple supply lines to the Satellite, you ordered the use of
the unchecked inlets first
d. After positioning members with handie talkies at the deluge gun and supply pumper, you
started water in the deluge gun on the order of the Battalion Chief designated as the Water
Resource Officer.

3. C

It is necessary to use the unchecked inlets first,
which will permit the use of the gated inlets to augment the supply without the necessity of
shutting down.

4.4 The use of a drafting site should be considered only if a fireboat cannot supply units of
the Satellite Water System due to inaccessibility, low tide, etc. Drafting is a time
consuming operation with many variables

5.3 Positioning of the Satellite Apparatus for use of deluge guns is much like deckpipe
placement. The further from the building, the better the angle achieved as the nozzle is
directed to higher floors. The best position is with the apparatus far enough from the
building so as to permit the deepest possible stream penetration.

7.4 To insure adequate water delivery and to effect safety controls, members with handitalkies
shall be positioned at deluge guns, manifolds, pumpers, and shut off gates of
appliances supplied by a Satellite Unit(s).

7.6 Satellite deluge guns, due to their powerful streams, shall not be placed in operation
except on orders of the Incident Commander.

carried on the Satellite. Select the incorrect characteristic mentioned by the Chief. (5.5)
a. The manifold has a 5” inlet and a Ross relief valve
b. Two firefighters can easily carry the manifold
c. The manifold has two 3” outlets and four 2 ½” gated outlets
d. The manifold’s supply line may come from a 2,000 gpm pumper or any conventional

4. A

5.5 Satellite Units carry a manifold, which consist of a 4 1/2" inlet supplied by a 5" hose,
four 2 1/2" gated outlets, two 3" outlets, and a Ross Relief Valve. The newest manifolds,
presently carried by all units of the Satellite System, are portable and are capable of being
wheeled by one member or easily carried by two. Supplied remotely by 2,000 G.P.M.
pumpers or conventional pumpers, manifolds are effective at large operations where a
centrally located supply of water can contribute to the rapid stretching of individually
controlled hoselines.


6. When the hydrant size being used to supply the Satellite water system is less than
_____inches it is recommended that a second hydrant or another pumper augment the supply of
water. (6.2)
a. 6
b. 8
c. 12
d. 16

5. The FDNY handie talkie (H/T) has channels that send and receive messages using two
different types of technology; simplex and duplex. During the recent training course for the
“Communications Engines”, the instructor made the following statements about simplex and
dulplex channel capabilities. Which is the incorrect statement? (1.1)
a. H/T channel 1 is a simplex channel which means the message is transmitted by one H/T
will be received by another H/T on the same channel
b. H/T channel 11 is a duplex channel which means a handie talkie transmits a message on
one frequency but receives a signal back on a different frequency
c. A repeater is required to boost the signal strength for duplex systems
d. H/T channel 10 which allows CFR-D Engines to communicate with Bureau of EMS
Ambulances, is a duplex channel

5. D

1.1 The FDNY primarily communicates at fires and emergencies using handie talkie (HT)
radios (Motorola XTS-3500, Models I and III) programmed on ultra high frequency
(UHF) band (406-512 MHz) frequencies. The radios are programmed using analog
technology with both simplex and duplex channels. Simplex channels transmit and
receive (point-to-point) on the same frequency. The simplex HT channels are 1, 2, 3, 4,
5, 6, 7, 8, 10, 13 and 16. When using simplex channels, a message transmitted by a HT
will be received by another HT on the same channel if it is within range of the
transmitting radio. The range of a HT is determined by many factors including wattage,
antenna, topography, battery strength and obstructions. Duplex channels transmit on one
frequency but receive a signal back on a different frequency; therefore communications
on these channels is only possible when used in conjunction with a duplex UHF repeater
system. The duplex HT channels are 11, 12, 14, and 15.
Note: Channel 9 is a digital channel for future use.


6. Some buildings and other infrastructure such as tunnels and large transportation hubs have
installed radio repeater systems for use by their employees and the FDNY. Which is the only
correct statement about FDNY policy and these ARCS? (2.1.1)
a. Some buildings’ radio repeaters have FDNY H/T repeater channels 14 and 15 programmed
into it for FDNY use
b. If a building’s radio repeater does not operate on an FDNY radio frequency, that system
cannot be utilized by FDNY H/Ts.
c. Use of so-called “In-house” radios, provided by building personnel, should be avoided due
to unreliability and personnel accountability difficulties
d. Buildings with a “leaky cable” require FDNY H/T duplex channels to be programmed if
FDNY H/T are to utilize the system

6. B

2.1.1 Types:
A. Duplex UHF Repeater (FDNY Programmed) - has a transmitter/receiver radio
which receives a signal on one frequency and simultaneously re-transmits it on
another frequency in the same UHF wavelength band. To allow the FDNY to use
our HTs with this system, the radio repeater is programmed to our duplex radio
frequencies. NYC Transit, WTC 7, and PATH Station (WTC) are examples of
this type radio repeater system.
B. Duplex UHF and Duplex VHF Repeaters (Proprietary) - some building
owners and agencies have maintained radio repeaters in their facilities which do
not operate on our frequencies. These systems cannot be utilized with FDNY
HTs. Generally, there are a limited number of in-house, UHF or VHF radios
stored at the site for use by FDNY members. The Incident Commander should
assign radios only as needed since there may also be no replacement batteries.
The Javits Center, Macy’s Department Store, and Grand Central Terminal are
examples of locations having these types of repeater systems.

b. Although Protein foam is not carried by the FDNY, it might be encountered at some bulk
c. A class “A” combustible materials fire in the hold of a ship may be extinguished with Hi-
Ex foam
d. Aqueous Film Forming Foam (AFFF), which is used in our 2 ½ gallon foam extinguisher,
is the one foam that can address all of the FDNY’s foam needs.

1. D

2.3.1 There are a wide variety of foam concentrates, each designed to behave in slightly
different fashions for a specific purpose. There is not any one specific foam
concentrate that will solve every problem the department faces. Different
concentrates may be required for different fuels. Concentrates that work well on
most fuels have other drawbacks that prohibit their use in everyday operations,
such as freezing considerations or corrosiveness of the concentrate. For this
reason, the FDNY finds it necessary to utilize a number of foam concentrates.


2. Select the correct statements about the use of foam in the FDNY (2.2 C, 2.4 A,
2.3.5, 4.2)
a. When a pre-mixed foam solution is used from an extinguisher a foam handline should be
made ready
b. It is permissible, under certain circumstances, to pour foam concentrate into the booster
tank of an Engine apparatus
c. The pour points of all foam concentrate used by the FDNY is above freezing
d. Different types of foam concentrate should never be mixed for storage in tanks
e. Two different types of low expansion foam may be used simultaneously
f. Hi-Ex and Low Expansion foam may be used together
g. Foam cannot prevent ignition, it is only intended to extinguish active flames

2. A, B, C, D, E


3. Mixing water and foam concentrate in the proper ratios will produce foam solution; FDNY
members have several options to achieve this mixture. Which choice indicates an incorrect
understanding of the FDNY foam policy? (2.4)
a. One method to make foam solution is by inserting an eductor in the hoseline which will
mix foam concentrate into the flowing water
b. The easiest method to make foam solution is to utilize the Foam Injection Metering Module
(FIMM) found on all new (2012) FDNY engine apparatus
c. When using the FIMM, concentrate is injected into the pump where it mixes with water
and is discharged as foam solution. No eductor is needed.
d. If an eductor is not available concentrate can be dumped directly into the booster tank. The
engine being used should not be connected to a hydrant.

3. B

Foam solution can be produced by injecting a supply of concentrate at the proper
proportion into a pumper that is also receiving a source of water. The foam and
water mix in the pump and are discharged as solution. This is accomplished by
means of the Foam Injection Metering Module (FIMM) built into the Satellite
pumpers. Satellite Units also carry a portable FIMM, which can be used if the
built-in FIMM is out-of-service or the back-up Satellite Unit with a conventional
pumper will operate


4. You are a Battalion Chief working in Battalion 5 on an overcast Saturday day tour. In
preparation for supervising multi-unit drill you review the companies assign to Battalion 5.
When you notice that Engine 13 has a Foam Carrier you write down a few notes about Foam
Carriers. Which of the following are incorrect? (6.3)
a. Foam carriers cannot pump concentrate to other units while also being supplied with water
and used to for direct fire attack
b. All Foam Carriers carry 1000 gallons of fluoroprotein concentrate
c. A 7500 CFM Hi-Ex foam generator and 50 gallons of Hi-Ex concentrate are stored on the
Foam Carriers
d. When special called to alarms, a maximum of three members are permitted to ride in the
Foam Carrier
e. Foam Carriers have the ability to pump concentrate to the Foam Tender
f. If a Foam Carrier is designated as an attack unit on a gasoline truck fire, a water source
should be identified prior to the units arrival

4. B, C, D

6.3.1 For incidents that exceed the foam capabilities of the first alarm units, the
Department has placed 10 Foam Carriers in service. These units are pumpers that
have been specially outfitted for foam operations. They carry no water; instead
their booster tanks are filled with 1000 gallons of Fluoroprotein concentrate or
Alcohol Resistant Fluoroprotein Foam (Fluoropolydol). They are equipped with
a preconnected 310 GPM foam deck pipe and portable eductors for hand line
operations as well as 10 lengths of 3½" hose for water supply. They also carry a
7500-CFM Hi-Ex foam generator. Due to weight restrictions, they shall carry
five 5-gallon cans of Hi-Ex and five 5-gallon cans of Alcohol Resistant
Fluoroprotein foam concentrate. Also, a maximum of two members, including
the Chauffeur, shall be permitted to ride in the Foam Carrier.


5. A covering Deputy Chief unfamiliar with the capabilities of the Satellite Units with respect
to the FDNY Bulk Foam Delivery System made the following statements during MUD. Select
the only correct statement. (6.4.1)
a. The Foam Injection Metering Module needs to be attached to any inlet of the Satellite’s
regular 2,000 gpm pumper.
b. The 500 gpm aerating foam nozzle carried by the Satellite can be placed directly on the
discharge threads of any engine’s deckpipe after it is fitted with a special adapter
c. The 1,000 gpm Angus Cannon can be attached directly on the discharge threads any Tower
Ladder waterway or Satellite monitor
d. Satellites carry approximately 160 gallons of Hi-Ex concentrate and a Hi-Ex foam

A. The units of the Satellite system provide three key components of the Foam
Delivery System:
1. The 2,000-gallon per minute pumpers provide the proportioning function
through their FIMM when concentrate is pumped into it.
2. The accompanying Satellite apparatus provides large capacity nozzles;
both 500 GPM and 1,000 GPM aerating foam nozzles. The 500 GPM
model may be placed directly onto the discharge threads of any
2½ appliance, including a Tower Ladder.
3. The 1,000-gallon per minute Angus Cannon can be used on the Satellite
monitor or can be fitted with a special adapter for attachment to any
Tower Ladder waterway. The Satellites carry the adapter and the
wrenches necessary to fit the 1000 GPM Angus Foam Cannon to
Tower Ladders.
B. The Satellites carry a 7,500 CFM High Expansion Foam Generator.
C. They also carry approximately thirty-two 5-gallon cans of Hi-Ex

8. The FDNY uses several different types of foam. Which are the correct statements?
(3.1.2, 3.2.1, 3.4.2, 3.5, 3.6.3)
a. 5-gallon containers of Fluoropolydol concentrate are color coded brown
b. Alcohol resistant foam is the superior extinguishing concentrate for both hydrocarbons and
alcohol fuels8. B, E
c. AFFF is the most widely used concentrate in the FDNY
d. Limited supplies of Alcohol Resistant Aqueous Film Forming Foam are stocked by the
Haz Mat Unit
e. A dry chemical extinguisher should be discharged into the foam stream to extinguish three
dimensional fires of burning fuel.

8. B, E

3.1.2 Distribution
Fluoroprotein foam is the most widely used concentrate in the department.
Five-gallon cans are issued to every engine and ladder company. It is stored in
bulk on the Foam Tender and in the Foam Carriers. Marine companies also are
issued 55-gallon drums of this foam.

3.5 Foam Concentrate Identification
It is imperative that the correct foam concentrate is used for the correct situation.
To insure that the foam concentrates do not get mixed, they are color-coded (banded)
around the top, as follows:
• Fluoroprotein BROWN
• Alcohol GREEN
• Hi-Expansion YELLOW

3.4.2 Distribution
Although the FDNY does not stock or use ARAFFFs, it is very common in the oil
industry and could be encountered at any operation involving mutual aid
