The nukeALERT is designed to meet extreme environ-
mental standards for rain, shock and vibration. The
unit is sealed to reduce intrusion from dust, humidity
and salt fog. The unit, including top display, may be
cleaned safely with mild soap and water using a
warm, wet cloth.
Battery Issues and Maintenance
The nukeALERT is powered by two AA Alkaline
batteries (installed at factory) which under a normal
duty cycle (on 8 hours a day in detection mode, off
16 hours) will operate in detection mode for two years
without replacement. A low battery indicator (LED
will display “L”) will inform the operator that batteries
should be replaced. While a certain reserve is designed
into the nukeALERT once a low battery alert is
displayed, batteries should be replaced (use small
Phillips head screwdriver to release battery door on
bottom of unit) as soon as possible to allow robust
operation in the event future multiple alarms are
encountered.
Failure Mode
If the unit is unable to achieve detection mode for
any reason, a FAIL indicator will be displayed. The
nukeALERT will continually display each character in
sequence – “F”, then “A”, then “I” and then “L”.
If failure mode occurs (most likely due to a significant
change in location of operation), turn power off to the
nukeALERT and then turn unit back on and allow it
to re-calibrate (in new location). If the nukeALERT
continues to go into failure mode following attempt
to re-calibrate, notify customer service for assistance.
