Commissioning

The VES-A00-P has been designed to simplify commissioning processes. The AutoLearn function allows the
unit to assess its environment and setup appropriate alarm and flow thresholds.
The detector is programmed using the Xtralis VSC software.
Once the VES-A00-P detector has been commissioned, it will report alarms and faults according to the
parameters defined during installation.
Note: Detectors should be commissioned with a smoke test. As part of commissioning, the installation
should be verified using a smoke detector tester. Xtralis recommends the use of SmokeCheck
HSI Fire for this system test.
Prior to commissioning the detector:
1. Check that the pipe network is clean and correctly fitted with all joints correctly seated and sealed
(except the endcaps and the pipe which enters the detector which must not be glued). Ensure that the
relevant pipes are selected as in use in Xtralis VSC.
2. Check that the power is connected and on. Ensure that the pipe flow rates comply with the minimum
requirements listed in Section 3.1. Ignore any faults during this time.
3. Set the Pipes in Use value in the Airflow configuration options.
4. Set the aspirator setting to the value used when designing the system in ASPIRE to achieve the required
transport time.
5. Normalize the airflow. This takes approximately 3 minutes, after which the pipe flow rates (%) should be
close to 100%.
6. Reset the detector after normalization. It should now be running without faults, providing the flow rates
are maintained as indicated in Section 3.1.
It is important that the protected environment is working under normal operating conditions when operating the
AutoLearn processes.
Xtralis recommends that a 14 day period is used.
After AutoLearn is complete, review to confirm that the thresholds are within the range allowed by local codes
and standards.
For code-specific information, see Codes and Standards Information for Air Sampling Smoke Detection on
page iii.
Note: Setting the Lowest Alert Threshold
For optimum sensitivity and performance, it is recommended that the lowest alert threshold for VES is set no
higher than the lowest Fire 1 level divided by the number of pipes in use.
Example 1:
Set the lowest alert threshold to no higher than lowest Fire 1/ #pipes in use.
E.g.:
Or

Fire 1
Pipe 1 0.3 %/m (0.1%/ft)
Pipe 2 0.25%/m (0.08%/ft)
Pipe 3 Not in use
Pipe 4 Not in use
0.25
%/m = 0.125 %/m
