Testing
Note:
Testing should only be carried out by qualified personnel. Before undertaking any testing, ensure
that the proper authorities have been informed and that the unit has been isolated from the fire
control panel if necessary to prevent unwanted alarms.
7.1
Point Detectors
With the unit powered up and top cover removed, the detectors can be tested for functionality using a low
concentration smoke source or aerosol point detector spray.
The detector can also be tested by placing a magnet below the LED at the 7 o’clock position on the detector
rim. This test electronically simulates the effect of smoke in the sensing chamber.
7.2
System
The installed system must be checked with the top cover securely fitted.
As a minimum, smoke should be introduced to the furthest sampling point from the ILS-2 unit on each branch
of the pipe. The choice of smoke source is dependent on the installation but in all cases the smoke must be
present for the duration of the test – aerosol sprays for point detectors do NOT work on aspirated systems.
If it is possible to get close to the sampling point then a basic, functional check can be carried out with smoke
matches or lighted taper etc. but for measurable performance tests then refer to Appendix A of the FIA Code
of Practice for Aspirating Systems to select the appropriate test for the installation.
