3.7. Alarms Reset or Acknowledge
When the monitor reaches an alarm set point, the audible, visual, and vibrating alarms will be
activated to alert the user.
Alarms are individually programmable to be either:
• Latching - alarms are active until the user resets by pressing and holding the R button after
the gas readings have returned to a safe level.
• Non-Latching - alarms will reset automatically when the gas readings have returned to a
safe level.
The audible alarm on each pre-set alarm can be muted for 60 seconds by pressing and holding
the R button. After this time, should the gas value remain out with the pre-set alarm limit, the non-
latching audible alarm will become active again. If latching, the audible alarm will become active
again regardless of gas value.
3.7.1. Confidence Signal
During normal operation, the monitor sounds a confidence beep and illuminates the green LED's
briefly every 15 seconds. This function informs the user that the monitor is operating correctly.
