2024 SYSTEMS VERIFICATIONBICSI FINAL EXAM WITH CORRECT
ANSWERS
Structural Steel members (Red Iron) - CORRECT-ANSWERSShall not be used
directly to support cable, but may be used for the attachment of proper
cable supports
In case of electrical fires, protection involves 4 (RACE) steps:
Rescue - Get people out of danger
Alarm - Sound alarm; call for help
Confine - De-energize circuits, close windows and doors, deactivate HVAC
systems.
Extinguish - All TRs and ERs should have fire extinguishers or fire
suppression systems designed to fight electrical fires.
There are 6 steps to safely assist others without endangering yourself:
1. Survey the scene - check for hazards and ask questions
2. Notify someone - if a person attempts to rescue alone they can become
overwhelmed by unforeseen hazards
3. Secure the area - turn off any sources of hazards, circuits, gas, water
mains, etc. and move the person to a safe area only if it will not harm them
to do so.
4. Check the injured persons ABCs
A - Airway
B - Breathing
C - Circulation
5. Contact Emergency Medical Service - EMS and relay the information
collected in the initial site survey.
6. Survey the scene - complete a seco
Ladder / Lift Safety - CORRECT-ANSWERSFall protection is required whenever
a person is exposed to a fall hazard of more than 1.83 m (6 ft). PFAS includes
a full-body harness and at least (1 lanyard in a boom lift and 2 lanyards
whenever the installer leaves the safety of the elevating device or is using
catwalks to allow at least one lanyard attached to a safety support at a time
when moving along catwalk for 100% contact), a shock-absorbing lanyard,
and a secure anchorage point capable of supporting 2,268 Kg (5,000 lbs)
Never use conductive ladders - use ladders made of fiberglass or dry wood.
,Many sites don't allow metal or wood ladders. When working over 3 steps
high a fixed or mobile scaffold is recommended.
Extension ladders should always overlap between sections by at least three
rungs and the top of the ladder should extend up to the work area and .9
meters (3 ft) above the roofline. The horizontal distance from the base to the
wall should be 1/4 the working length of the ladder.
A personal lift is required when a ladder or scaffold cannot be used. All
operators must be trained and have received proper instructions before
operating aerial platforms. Stay at least 3 m (10 ft) from exposed energized
circuits operating at 300-50,000 volts (V). The AHJ may require that live parts
operating at 50 V or more be guarded against contact.
There are two types of lifts:
Boom - Boom supported elevating working platform, is a basket mounted on
the end of an extendable arm in which the user stands. A full-body harness
and lanyard are required for anyone in the basket of a boom lift.
Scissor - (Self-propelled) work platform mounted on a large scissor jack,
which is stable but not flexible in its use because they only extend straight
upward. OSHA does not require a body harness and lanyard for scissor lifts.
Cross Connects, Backbone Cabling, and Administration - CORRECT-
ANSWERSAdministration systems include requirements for; identifiers - that
serve to locate the element record and administration scheme such as the
standards found in ANSI/TIA 606-B, records - which can be paper based,
spreadsheets, database programs, or computer programs specially designed
for that purpose, and labeling - with a variety of methods to display
identifiers for the buildings, pathways, spaces, cabinets, racks, cabling,
connectors, the choice of material, fastening method, environmental,
performance, and security issues. Common methods for displaying identifiers
include bar codes, graphics, labels, tags, and electronic identifiers
There are four classes of administration:
Class 1 - 1 ER which is the only telecommunications space on the site
Class 2 - 2 or more telecommunications spaces in a building
Class 3 - Multiple buildings at a single site
Class 4 - Multiple sites or campuses
Data Centers - are buildings or portions of a building whose primary function
is to house a computer room, including the data center electrical rooms,
mechanical rooms, storage rooms, staging rooms, operations and command
center, and other spaces whose primary functions are to support the
computer room.
, For redundancy, in accordance with ANSI/BICSI-002 stamdards, classes of
Data Centers have been established.
Class 0 - a single path data center that meets the minimum requirements
but cannot be classified as Class 1 or higher
Class 1 - the single path data center
Class 2 - the single path data center with redundant components
Class 3 - the concurrently maintainable and operable data center
Class 4 - the fault tolerant data center that contains two separate
infrastructures with their own set of redundant components.
Some of the key areas include a Telecommunications Entrance Room that
contains the External Network Interface (ENI), wh
American Wire Gauge (AWG) - CORRECT-ANSWERSRoughly represents the
number of steps that were involved in the process of wire drawing.
Smaller Numbers: Larger wires (fewer drawing steps are involved)
Larger Numbers: Smaller wires (more drawing steps are involved)
A gauge change of 3 numbers: Doubles or halves the conductors resistance
and cross sectional area
A gauge change of 6 numbers: Doubles or halves the conductors diameter
Resistance, Inductance, Capacitance and Impedance - CORRECT-
ANSWERSResistance: the property of a conductor to resist the flow of
electricity through it. Expressed in Ohms - One ohm of resistance will allow
1A of current to flow when 1 V of electrical pressure is applied where V is
voltage in volts, I is current in amperes, and R is resistance in ohms.
Resistance changes in proportion to length. High temperatures increase the
conductors resistance by approximately 2% for each 10 degrees Fahrenheit
(5.5 C).
Inductance: a property of an electromagnetic field built around a conductor
that opposes any changes in current flow in a circuit, both ac and varying dc.
The basic unit of inductance is a Henry (H). Inductive coupling is the transfer
of energy from one circuit to another through this field. Inductive reactance
is a force that opposes change in the direction of current flow on a
conductive path. Is measured in ohms. Directly proportional to the
frequency.
Capacitance: a property of conductors that allows storage of electric charges
when potential differences (voltages) exist between conductors. Cause a
voltage difference between two wires when separated by insulation, resulting
in a buildup (or storage of electric charges) of capacitance between the
wires. Is measured in farads (F). Normally measured in microfarads (one
