The standard floor space coverage area for each building automation system (BAS) is a BAS outlet or device for every ________ of floor space.
- A . 9.3 sq m (100 sq ft)
- B . 23 sq m (250 sq ft)
- C . 31 sq m (330 sq ft)
- D . 56 sq m (600 sq ft)
- E . 84 sq m (904 sq ft)
Perimeter raceway systems should be used primarily for:
- A . Underfloor pathway
- B . Apartments or hotels where molding is accessible in the work area
- C . Warehouses with minimal telecommunications services
- D . Small floor areas where the majority of telecommunication services will be along the walls
- E . Equipment rooms where cable tray is cost prohibitive
You are designing a horizontal distribution system that will have a zone box located 71.6 m (235 ft) away from the telecommunications room (TR). A 50 mm (2 in) conduit is designed from the TR to a pull box located 36.6 m (120 ft) away from the TR. A 1 1/2 inch conduit is designed from the pull box to the zone box located 35.1 m (115 ft) beyond the pull box.
Assuming no conduit bends, and excluding the TR and zone box, what is the total number of pull boxes/pull points required in this horizontal conduit system between the telecommunications room (TR) and zone box?
- A . 2
- B . 3
- C . 4
- D . 5
You are designing a horizontal pathway system where you will provide 100 mm (4 in) conduit and pull boxes. The building architectural elements will only allow for a single layer of conduits (not stacked). The main horizontal pathway system consists of five 100 mm (4 in) conduits. Large single sheath copper cables are not expected to be placed.
Which of the following is the MINIMUM width pull box that is to be provided?
- A . 600 mm (24 in)
- B . 900 mm (36 in)
- C . 1220 mm (48 in)
- D . 1520 mm (60 in)
- E . 1830 mm (72 in)
A conduit run is installed from the ER to a TR. It has two (2) 90 degree bend and a length of 20 m (65 ft).
What will be the MINIMUM test rating of the pull cord left in the conduit?
- A . 20 kg (44 lb)
- B . 40 kg (88 lb)
- C . 60 kg (132 lb)
- D . 90 kg (200 lb)
- E . 100 kg (220 lb)
Cables are installed in a ceiling in a straight line. The ceiling run is 60 m (200 ft) in length.
What is the MINIMUM number of J-hooks required to support the cables?
- A . 20
- B . 30
- C . 40
- D . 50
- E . 60
An existing ceiling raceway system has 115,000 sq mm (177 sq in) of cross-sectional area available for distribution of cable runs.
How many can be served by the existing system?
- A . 115
- B . 160
- C . 177
- D . 189
- E . 195
The standard floor space coverage area for each building automation system (BAS), is a BAS outlet or device for every_______ of floor space.
- A . 9.3 m 2 (100 ft 2)
- B . 23 m 2 (250 ft 2)
- C . 31 m 2 (330 ft 2)
- D . 56 m 2 (600 ft 2)
- E . 84 m 2 (904 ft 2)
Which of the following statements best describes what a backbone distribution system typically provides?
- A . Cabling from the HC to the WA
- B . Pathway from the HC to the WA
- C . Conduit in a building riser
- D . Building connections between floors in a multistory building
- E . Copper cabling installed in a large building
When designing a backbone distribution system, you will need to include a telecommunications enclosure (TE). A TE can be defined as a:
- A . Splice point for copper cabling only
- B . Point where the backbone cabling interfaces to the horizontal cabling and may be utilized in place of a traditional Telecommunications Room (TR)
- C . Location for housing building cross-connect cabling only
- D . Location to house the splice transitioning from outdoor to indoor cabling only
- E . Facility to store slack copper and fiber cables
