Maximum smoke transport time
Maximum smoke transport time is measured by introducing a small quantity of
smoke into the furthest sample hole and then measuring the time between first
introducing the smoke and observing a response at the detector.
The results of this test and the calculated maximum transport time from PipeCAD
must be recorded on the check sheet. Measured transport time less than the
calculated time is acceptable.
To measure the maximum transport time:
1. Determine the furthest sampling point from the detector.
2. Allow test smoke to enter the pipe at the furthest sampling point.
3. Record the amount of time it takes for the detector to respond.
Notes:
Test all pipes individually to confirm full integrity.
Ensure that any measured transport time matches requirements in the
installation design specification, where applicable.
Fault detection
Block and unblock all pipes to ensure that low flow and high flow faults are
reported correctly (note that there is a default delay of 90 seconds before a flow
fault is reported).
Disconnect the battery and then the mains power supply to ensure that power
supply faults are reported correctly.
Alarm detection (smoke tests)
Caution: These tests may activate installed point detectors at the site. Always
ensure that site personnel are consulted before smoke tests are performed and
that all measures are taken to avoid unwanted alarm activations.
Smoke tests measure the amount of time to activate alarm states. The test
should be repeated at least three times with consistent results.
Typical smoke tests include:
• Wire burn tests for Class A and Class B installations
• Smoke pellet tests for Class C installations
Use of canned smoke is not recommended to test the detector as the particles
don't last long enough to travel the full length of the sampling pipe.
