Warm smoke testing uses a vaporised mineral oil base product at high temperatures to create smoke and to simulate the conditions that activate a building’s smoke control system. The test verifies that smoke detectors respond correctly, smoke mode sequences activate in the correct order, smoke exhaust fans reach the required airflow, and pressurisation systems achieve the specified pressure differential across stairwells and lift shafts.

The test is called “warm” smoke because the smoke is introduced at an elevated temperature to activate heat-sensitive detectors, as well as smoke detectors.

Warm smoke testing frequently identifies deficiencies in smoke control sequences, fan performance, or control programming that require rectification. QPT documents all deficiencies with photographic evidence and can manage rectification within the same scope.
