(such as radio alarms) or units generating high levels of electrical energy (such as large electric motors or generators). Table 3 on page 17 contains a list of procedural guidelines for installation of the Nano detector. LaserSense Nano Aspirating Smoke Detector Installers Handbook...
Ensure that the sampling and exhaust pipes are securely seated in the pipe ports before securing. If using a piped exhaust connection, be sure that the sampling and exhaust pipe are fitted into the relevant port as shown in Figure 8 on page 18.

This test should be repeated at least three times with consistent results. The recommended smoke generating medium is canned smoke or a wire burner. Smoke from a punk or cotton wick is also acceptable. LaserSense Nano Aspirating Smoke Detector Installers Handbook...
Be sure to keep a safe distance away while voltage is being applied. A wire burner/canned smoke test could activate spot-type detectors. Caution: This test may be undertaken in underfloor spaces or ceiling voids where rapid airflow may render Test 1 unsuitable. LaserSense Nano Aspirating Smoke Detector Installers Handbook...
