Vizor Electronic Dry Pipe Accelerator

Quick-opening accelerator

Electronics don’t have to be complex: Compared to the many complex parts of traditional mechanical accelerators, the Vizor electronic accelerator has just one moving part.

  • Provides operation of a dry pipe valve within four seconds
  • Unique air-pressure monitoring triggers upon detection of a sustained drop in air pressure
  • Available in the US and Canada


Vizor’s quick trip time cuts fluid delivery time on an average-size system by nearly 20 seconds. The accelerator takes two pressure readings every second, which allows it to differentiate between normal system pressure loss over time and the operation of a sprinkler. This means reduced false trips and earlier response to an activated sprinkler.
