1. Press and Hold the button for three seconds. The detector displays Starting Bump test.
Bump test started is displayed, and then the detector makes noise, flash, and vibrate.
2. The detector will prompt you Did you see and hear the alarms?, select Pass, and Press and
hold for three seconds to confirm that the visual, audible, and vibrator alarms work
correctly.
An Audio-Visual test passed message is displayed. Skip to Step 5.

b) Press the button to skip gas application and follow on-screen instructions to end the
Bump Test. Bump test results are displayed, and the test ends.
4. If you want to apply gas, follow on-screen instructions. Wait for about 30 seconds; gas
measurements are displayed for each pertinent gas sensor. A Bump Test pass confirmation
is displayed.
5. After the Turn gas off message is displayed, remove the hose from the pump inlet. The
detector will remain in alarm until the gas clears from the sensors. Bump test results are
displayed showing check marks next to the tested sensors. These sensors reset to the
number of days until the next Bump Test is due.
6. Press the button to finish the procedure.
Honeywell recommends to bump test the sensors before each day's use to confirm
their ability to respond to gas by exposing the sensors to a gas concentration that
exceeds the alarm setpoints.
