As with any smoke detection system, to maintain Aspirating Smoke Detection (ASD) systems at their peak performance, routine test and inspection are required at a frequency dictated by local codes and standards, or more frequently as may be required by the specific application requirements.

Benchmark testing from a point along each pipe run furthest from the ASD detector provides a means to validate system and pipe network integrity. When properly designed and installed, benchmark test points are positioned at an accessible height and location, and provided with a means to open temporarily when testing.

The Xtralis Quick Connect Benchmark Test Point kit has been designed to simplify construction and enhance suitability providing robust, normally closed fail safe operation. An accompanying test point label provides commissioning technicians a method to record benchmark commissioning data using a permanent marker on a moisture resistant label. This label is placed just above the benchmark quick connect fitting on each pipe run thereby making the data readily accessible for future inspections.

While there are requirements in various codes, standards and end user practices for acceptable smoke transport time from the last sampling point, benchmark data needs to be established to qualify pipe network integrity and airflow through all other sampling points. The Benchmark Test Point should not be confused with the last sampling point on the pipe run. ASPIRE calculations must be available showing expected smoke transport time at the last sampling point and as well the test point transport time when opened. The benchmark is established by measuring the test point smoke transport time and the resulting value documented at the test point for subsequent testing.
