Bump Test - Honeywell Sensepoint XRL Instruction Manual

4.5 Bump Test

If repeated calibration attempts continue to fail, replace the gas sensor
with a new one, and then try again. See
36.
This section describes how to perform a bump test. For details about
the mobile app, see
Bump testing is the process of exposing the gas sensor to a known
concentration of reference gas that is greater than the low alarm
threshold in order to verify the proper operation of the gas detector.
1. Connect your smartphone with the target gas detector via
Bluetooth.
2. Place the detector in inhibit mode by using the inhibit control on the
mobile app.
3. Connect a cylinder of reference gas to the target detector using a
suitable tube connected to the gassing port or the calibration cap.
For details about how to use a calibration cap, see
on page 31.
4. Connect your smartphone with the target detector via Bluetooth.
5. Apply the bump test gas to the detector.
NOTE
For CO versions operating in UL 2075 alarm mode, apply 100
ppm of carbon monoxide at a flow rate of 500 ml/min for 5
minutes.
6. If the detector fails the bump test, check and if necessary, calibrate
the detector.
NOTE
Perform a bump test at least twice a year.
