6.2 System Commissioning
Once the VESDA system has been installed, its performance and pipe network integrity can be
verified using the ASPIRE2 pipe modelling program. A range of sampled air temperatures may be
input to determine Maximum Transport Times for each zone. Calculated Transport Times should
be applied conservatively. Smoke tests can then be used to check system performance for both
smoke detection and pre-action suppression activation.
6.3 Service And Maintenance
The VESDA system shall be serviced and maintained according to both the local codes and
standards and the instructions provided in the Maintenance section of the VESDA System Design
Manual
[2]
.
The frequency of sample pipe inspection and testing can be determined by the rate of ice build-up
to ensure that sample holes do not become blocked.
