•When bump test fails
Q: Where can I get information for the installation, commissioning and servicing of VESDA
Sensepoint XCL – Micro / Large Bore gas detectors?
A:
•VESDA Sensepoint XCL – Micro Bore Installation Manual: Doc. No: 33889.
•VESDA Sensepoint XCL – Large Bore Installation Manual: Doc. No: 35563.
Q: What is Sensepoint App?
A: Sensepoint App is a smart device app that is used to connect and interact with VESDA
Sensepoint XCL detectors for commissioning, maintenance and general operation without the
need to open the detector. For details on Sensepoint App, refer to Sensepoint App User Manual
(Doc. No: 35245).
Q: What activities are performed through the Sensepoint App?

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).
•For calculating the number of sample holes VESDA Sensepoint XCL – Large Bore can support for
a given gas hazard refer to the Application Note Doc No: 35616.
