XT Series Personal Gas Detector
Warning: Read Manual Prior to Use
1. Introduction
The XT is a disposable, easy to use, personal gas detector, designed for 2 years continuous
monitoring of the atmosphere for potentially hazardous levels of oxygen deficiency or toxic gas.
SAFETY INFORMATION
Substitution of components may impair intrinsic safety
•
Do not activate the detector after the date on the packaging
•
Perform a self-test prior to each day’s use
•
Do not use in oxygen-enriched atmospheres
•
Periodically test the sensors response to gas by exposing the detector to a target gas
•
concentration that exceeds the alarm set points. Manually verify that the audible, visual
and vibrating alarms are activated
Exposure to extremely high levels of over-range gas may cause temporary loss of sensor
•
accuracy. Allow monitor to stabilize in zero gas atmosphere before reuse. It is recommended
to perform sensor response gas test prior to reuse.
IMPORTANT NOTICE
Honeywell Analytics can take no responsibility for use of its equipment if it is not done in accordance

To activate, hold Test Button (as shown below) for up to 20 seconds. The detector will emit 5 beeps
and 5 flashes. The XT will warm up for one minute, showing a countdown in seconds and the Test
Pass icon ( ) will be flashing. It will then set the remaining-life clock and perform a self-test. If the
detector passes, the Test Pass icon ( ) is displayed. If the Test Fail icon ( ) is displayed then the
detector has failed the self-test – please refer to the instructions in Section 6.

The XT is available with two types of display; Standard and Real Time. This section will illustrate
the difference between the two display types.
On XT’s equipped with the Standard Display, the remaining lifetime clock indicates how much
longer the detector will operate. This is shown on the display as a countdown of remaining months
(indicated by the icon), then days ( ) and finally hours ( ). The example in the table on the next
page shows 24 months remaining.

Should the Standard Display XT unit be exposed to a level of gas in excess of the alarm set points
the unit will display the concentration of the gas. If the measured reading exceeds the range of
the detector then the numerical digits will flash.
The Real Time Display XT displays the concentration reading all the time. The lifetime remaining
is displayed in the self-test mode.
