Product Type:Smoke Dispenser|Detection Type:Smoke|Intended Use:Commercial/Industrial

The Solo 330 dispenser is the most popular device, benefiting as it does, from a cup big enough for the great majority of detectors (particularly with the patented silicon diaphragm to enclose the sensing chamber) but still small enough not to be obstructive and unwieldy.


  • Pole not included
  • Dispenser and patented diaphragm contain particles – conserves test gas / smoke - note1
  • Test gas / smoke not directed at detector-sensor not swamped with particles and detector residue prevented - note2
  • Strong and durable yet lightweight for daily use - note3
  • Spring-loaded mechanism renders it touch sensitive – for suspended ceilings - note4
  • Clear cup and diaphragm enables view of the detector LED while testing - note5
  • Universal - suits most detectors - note6
  • Interchangeable with all other Solo tools on Solo poles
  • Lifetime Warranty
  • Smaller cup of Solo 330 contains vast majority of the world’s detectors without being unwieldy and oversized


Codes and standards require functional tests to introduce (simulated) smoke through the detector vents and into the sensing chamber. Magnetic testing is not acceptable. The user of a smoke dispenser for the release of smoke test aerosol for efficient activation of detectors is highly recommended.

  1. This is a patented elasticized diaphragm that enables just the sensing chamber of the detector to be enclosed within the cup and a sufficient seal achieved. Not needing to enclose the detector enables a smaller, less unwieldy cup to be used. The Solo range is unique in this feature (although, of course, larger cups are available for the largest detectors or those in 'cages'.
  2. Residue occurs when a liquid particle impacts a surface 'too early'. Hand held aerosols are often misused with this result. Not only does the Solo dispenser range prevent this inadvertent misuse but it also slows aerosol flow – very important for increasingly sophisticated detector algorithms that are 'knocked over' by fast moving aerosol
  3. We have been doing this for many years and we understand that these are field portable devices used by mobile engineers. They are well designed, well made and well backed up.
  4. In a feature invented specifically by the Solo range the springs in the dispenser are tensioned to neutralize the pressure of the aerosol valve – enabling aerosol (and detector) activation on suspended ceiling tiles that would otherwise have lifted. Though others have tried to copy the concept they have failed to make them operate nearly as well.
  5. Both cup and diaphragm need to be clear to enable sight of the LED. Sufficiently clear to see the LED.
  6. Universality is a theme throughout the Solo range. We achieve it through various design features not all of which are obvious and for it we draw on many years of experience around the world and, literally, hundreds (or perhaps thousands) of detector models / sizes / types with which we are familiar.

Great product
Great product. This was a replacement for the same item I have used for over 10 years. Received shipment in two days great service.
