Frequently Asked Questions
VESDA Sensepoint XCL–Micro/Large Bore Gas Detectors
Doc. 35229_03
Q: What are the benefits of remote gas sampling?
A:
For routine detector service / maintenance no need to:
•
Use special equipment to access high ceilings.
•
Enter areas of high risk or undergo training for access (machinery, high voltage, confined
spaces).
•
Access restricted areas (battery rooms).
•
Access concealed spaces (ducts, shafts).
•
Access secure areas (military).
•
Access 24x7 service areas (hospitals).
Q: What are the benefits of multi-point aspirated gas sampling?
A:
•
Greater area coverage than a spot (point) point gas detector – cost effective solution.
•
Increases confidence level where gas source is not precisely known or where environments have
variable airflows.
•
Reliable detection of gas dispersed under airflow conditions.
•
Single detector can simultaneously protect compartmentalised spaces.
•
Reliable performance in a wide range of environments – air drawn to the detector can be
conditioned to remove moisture, particulates and other contaminates that would otherwise impact
detector performance.
Q: How many sample holes does the VESDA Sensepoint XCL – Large Bore support?
A:
This will vary depending on:
•
Target gas concentration.
•
Number of sample holes upstream the VESDA Sensepoint XCL detector.
•
Dilution of gas in the pipe.
•
VESDA Sensepoint XCL lower alarm level (LAL).
Refer to the VESDA Sensepoint XCL Large Bore Alarm Setting Calculator Sheet (Doc. No. 35758) for
setting detector alarm levels for given target gas concentration and supported number of sampling
holes.
