The VESDA-E has the greatest sensitivity range of any Xtralis air sampling smoke detector to date. The VESDA-E sensitivity range is:
- A.
0.0015-6.25%obs/ft (0.005-20%obs/m)
- B.
0.0003-6.25%obs/ft (0.001-20%obs/m)
- C.
0.008-6.25%obs/ft (0.025-20%obs/m)
- D.
None of the above
Correct Answer
B. 0.0003-6.25%obs/ft (0.001-20%obs/m)Explanation
The correct answer is 0.0003-6.25%obs/ft (0.001-20%obs/m). This is because the VESDA-E has the greatest sensitivity range among all Xtralis air sampling smoke detectors. The sensitivity range refers to the ability of the detector to detect smoke particles in the air. The wider the range, the more sensitive the detector is to detecting even small amounts of smoke. Therefore, the VESDA-E has the ability to detect smoke particles ranging from 0.0003%obs/ft to 6.25%obs/ft, or from 0.001%obs/m to 20%obs/m.Rate this question:

When mounting a VESDA-E detector to the wall a minimum of 2 inches (50mm) of space is required between the ceiling and the detector. If a Stax module is to be added to the top of the detector the minimum space between the detector and the ceiling shall be:
- A.
3 feet (1 Meter)
- B.
2 feet (60 cm)
- C.
1 foot (30 cm)
- D.
.5 foot (15 cm)
Correct Answer
C. 1 foot (30 cm)Explanation
The correct answer is 1 foot (30 cm) because when a Stax module is added to the top of the detector, it requires additional space between the detector and the ceiling. Since the minimum space required between the ceiling and the detector without the Stax module is 2 inches (50mm), adding the Stax module would increase the required space.
