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 with the appropriate issue and/or amendment of the relevant manual. If further details are required which do not appear in this manual, contact Honeywell Analytics or their agent.
Honeywell Analytics shall not be liable for any incidental or consequential damages in connection with any deletions, errors or omissions in this Manual.

2. Activating the Detector
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.
XT Series Personal Gas Detector
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.
