Pipe Integrity Smoke Testing
1. Ensure the local fire panel is isolated from the external fire reporting
equipment and any automatic extinguishing or suppressant systems
are isolated
2. Introduce smoke directly into the farthest sample hole in the pipe run
and start the timer
3. Stop the timer when the detector registers smoke and record the
results
4. Compare the time expected with the actual recorded time
– If the actual recorded time is 20% or greater than the expected time,
check the pipe for breaks
3) Configuration and thresholds
• Configure the system (zones, remote modules, relays, GPI, reference,
Ethernet/ Wi-Fi)
• Set flow and smoke thresholds based on ASPIRE calculations, set
aspirator speed, and normalize airflow
• Print VSC Configuration file
