XT Series Personal Gas Detector 13
9. Safety Shutdown
In the event that the battery runs out before the end of life is reached (due to excessive alarms)
the battery icon will blink, the audible alarm will beep once every 15 seconds, and the visual alarm
will flash once every 15 seconds, until the Test button is pressed. The audible alarm will then be
turned off, and the detector will shutdown. A shutdown condition can also occur due to failure of
the electronic circuitry or sensor. The relevant error code is shown (Section 10).
Note:
Shut down conditions due to extreme temperatures can be reset by moving the
detector to a normal range temperature and pressing the Test button.
