Bump Test
The detector can be tested in two ways:
• Apply gas from a cylinder to the sensors manually through the calibration cap, and using the
Safety Suite Device Configurator (SSDC) software or the Device Configurator (DC) app.
• Use an IntelliDoX module.
Move to a normal atmosphere (20.9% v/v O

ability to respond to gas by exposing the apparatus to a gas concentration that exceeds the
alarm setpoints. Manually verify that the audible and visual alarms activate.
The combustible sensor is factory calibrated to 50% LEL methane. If monitoring a different
