note
In latching alarm mode, once an alarm occurs, the audible, visual and
vibrating alarms continue to operate even after the atmospheric hazard
has cleared. By pressing the ON/OFF button, the alarm will be cleared
(after the atmospheric hazard has cleared). Any subsequent alarm will
reactivate the audible, visual and vibrating alarms.
In non-latching alarm mode, should the gas alarm occur the detector
would enter alarm condition. When the reading returns to a normal level,
the audible, visual and vibrating alarms will stop.
If the measured reading exceeds the range of the sensor, the full-scale
value will blink.
See Section 5 Set-up Mode for more information on Latching/Non-
Latching Alarms
