A wind tunnel system for testing of smoke detectors

Antti Ahonen, Pauli Sysiö

Research output: Book/ReportReport

Abstract

A wind tunnel aerosol generator system for testing of smoke detectors according to the European standard proposal prEN 54-7 is described. The system comprises a thermally insulated wind tunnel, a unit for generating and measuring the specified air flow, a heater unit for controlling the air temperature, a pressurised air operated aerosol generator for producing the artificial smoke, and the necessary instruments for the smoke density and temperature measurements. The properties and the stability of the aerosol have been investigated by smoke density measurements using a combination of a standard ionisation chamber and two optical densitometers working at different wawe length ranges. Excellent long term stability and reproducibility are obtained.
