  • Page 14: Bump Testing (Gas Response Check)

    Bump Testing (Gas Response Check) All certified test gases supplied by AGS are classified as non-flammable and non-toxic, however, they may contain gas under pressure and may explode if heated to extreme temperatures and cause asphyxiation in high concentrations. Always use in accordance with the safety data sheet! Gas response checks are often referred to as a ‘bump test’.
  • Page 15 Installation, Operation & Maintenance ParkSafe Controller Step 2. Test Detector Access to the interior of the detector, when carrying out any work, must be conducted by a competent person! Apply a gas concentration ~50% higher than the alarm setpoint but do not exceed the upper limit of measurement! Ensure you have the correct calibration gas for the device type.
