Additionally, the XT will periodically check its battery, electronic circuit and sensor. If it fails the
Test Fail icon ( ) will be shown and the Test Pass icon ( ) will blink. If it passes then the Test
Pass icon will be displayed.
7. Testing Sensors and Alarms (Bump Testing)
To maintain optimal accuracy, the detector should be periodically supplied with a known
concentration test gas (bump test) and if the readings are outside of 15% of the applied gas
concentration, a span calibration should be performed, under conditions of standard temperature
(15°C to 25°C/59˚F to 77˚F) humidity and pressure. Follow local regulations and/or your company’s
policy on the frequency of bump testing. For more information on test gas, contact your local
Honeywell Analytics representative.
8. End of Life Alarm
When the XT has less than 1 day of remaining life it will flash the digits, as below:
End of Life Warning
End of Life Reached
When the XT’s life has ended the display will blink as shown above, the audible will beep once
every 15 seconds, and the visual will flash once every 15 seconds, and the vibrating alarm will
operate once every 15 seconds, until the Test button is pressed. The audible will then be turned
off, and the detector will shutdown, displaying the relevant error code (see Section 10).
