Bump Test
A bump test is the process of applying a small amount of test gas to force the detector into alarm.
Perform a bump test to validate that the sensors are responding correctly to gas, and that the
audible and visual alarms activate during an alarm condition.
To perform a bump test, complete the following:
1. Activate the detector. A bump test can be performed either during startup when the BUMP
DUE NOW screen displays or when in normal operation.
2. Attach the calibration hose (C2-HOSE1-1) to a 0.5 l/m Manual regulator (Part Number
REG-0.5) or a 1 l/m Demand flow regulator (Part Number REG-DF-1)
3. Connect the hose quick connector to the pump quick connector on the pump inlet to apply
gas.
4. The detector should enter alarm. Verify the audible and visual alarms activate, and that the
LCD readings match the span gas concentrations of the gas cylinder being used.
5. Disconnect the calibration hose from the detector. The detector briefly remains in alarm
until the sensors clear of the test gas.
Note: An IntelliDoX station (automated bump test) is required to log bump tests as an event. A
manual bump test will not be logged as an event.
