Method 2 - Using Artificial Smoke
It is important when using this method that only approved smoke canisters are used as other brands
may deposit residue within the detector sample chamber affecting the performance.
Smoke canisters approved for use on the Graviner Mk7 Oil Mist Detection system are:
HSI Fire and Safety SmokeCheck 25S
HIS Fire and Safety PurCheck
When using this type of spray canister, it will inject smoke at a rate where the rise of oil mist is rapid and
will pass through the alarm thresholds extremely quickly.
1. Push the nylon pipe of the smoke tester into the connector on the side of the detector base body
(refer to Figure 70).
2. Using a can of artificial smoke, spray enough artificial smoke into the pipe connector to cause
an alarm condition.
3. After tests are completed the maximum actual average level, Detector peak level and current
average readings should be erased.
