vi AutroSense Micra 10 Aspirating Smoke Detector Installers Handbook
UL 268 fire tests were passed with an installation as follows:
Total sampling pipe length: 160 ft. (single pipe)
Number of sampling holes: 10
Worst-case sampling hole sensitivity as indicated by PipeCAD:
1.28% obs/ft.*
Alarm factor:
1
Fire 1 alarm delay: 0 seconds
These settings gave satisfactory responses to the test fires in 120 seconds or
better. For the purposes of UL 268 compliance, these should be regarded as
worst case values. Layouts should be planned in PipeCAD and the indicated
worst-case hole sensitivity should be better than 1.28% obs/ft.*. Commissioning
smoke tests should be performed to ensure that the farthest sampling hole from
the detector is capable of generating a fire alarm within 120 seconds of receiving
smoke.
* The results should be verified at installation by entering the installed detector's
Fire 1 sensitivity (as indicated in the remote software histogram screen) into the
PipeCAD “Options/Calculation options/Detector sensitivity” field and recalculating
the layout results.
