Electric vs Pneumatic Release Explained for FireFlex Selector Users

Release type describes how the valve is triggered to open. Electric release depends on electrical detection and solenoid operation. Pneumatic release depends on air-pressure-based release logic.

  •  Choose electric release when the system is triggered through electrical detection and a releasing panel.

  • Choose pneumatic release when the design calls for air-pressure-based release logic. 

What each option means

Electric release

An electric release system uses electrical detection and a solenoid valve to trigger valve operation.

Choose it when:

  • The fire alarm or releasing logic is electrical
  • You want integration with detection circuits and releasing controls
  • The project specification calls for electric release

Pneumatic release

A pneumatic release system uses air pressure or pressure drop logic in the release arrangement.

Choose it when:

  • The design calls for pneumatic pilot operation
  • The releasing logic is based on air-pressure supervision
  • The selected system configuration specifically requires pneumatic release
Which one is better?

Neither is universally better. The correct choice depends on:

  • project specification
  • detection method
  • local approval requirements
  • system type selected
Easy selection rule

If the project is built around a releasing control panel and electrical detection, choose electric.
If the project uses pneumatic pilot logic, choose pneumatic.
