Report XF3033/R3 Smoke Sensitivity Testing of Residential Smoke Alarms

1 INTRODUCTION

Fire and Rescue NSW submitted samples of four different models of residential smoke alarm for Directional Dependence and Initial Sensitivity testing in accordance with AS 3786-2014.

This report replaced CSRO report XF3033/R2 dated 13 May 2016.

2 TEST PROGRAM

The following activities were performed to evaluate the sensitivity of each model of residential smoke alarm:

● Directional Dependence (Clause 5.2) test (one test on one sample of each of the four models); and

● Initial sensitivity (alarm response threshold) test (Clause 5.3) on all samples of each model.

The results of these tests are detailed in Section 3 of this report.

2.1 Test Samples

A summary of the submitted samples are detailed in Table 1 of this report.

4 REFERENCE INFORMATION

The following information is provided to assist in the interpreting of the results detailed in this report.

4.1 Obscuration vs. Ionisation data

The data shown in Figure 3 demonstrates the relationship between smoke density measured by the reference IR obscurometer (measured in dB/m) and by the reference measuring ionisation chamber (MIC, measured in terms of “MIC y”). Refer to Section C2 of AS 3786:2014 for details of the MIC and its response values.

4.2 Obscuration units

The data shown in Figure 4 and Figure 5 demonstrates the relationship between smoke density calculated in terms of the units of dB/m and %obscuration/m.
