Wind Alarms: IMPORTANT NOTE/DISCLAIMER    
It is important to note that cup anemometers (whether manufactured by Vector Instruments or anyone else) are not intrinsically fail-safe. Should the anemometer become disconnected, or should the rotor be damaged/jammed or come off, or the shaft/bearings sieze, it is possible for an alarm unit using it as a windspeed sensor to falsely indicate zero or a lower windspeed than it should which will probably mean that alarms could fail to go off when they should. It is of course also possible that a fault in the display/alarm unit could prevent an alarm being indicated too.

It is therefore not recommended that a single system be relied upon when incorrect operation, readings or alarms could be life-threatening or could result in injury to persons or property.

The likelyhood of incorrect operation can be reduced (but not completely eliminated) by...
  • Periodic visual inspection of the anemometer (to check for rotor damage)
  • Regular servicing and maintenance
  • Periodic factory recalibration and testing of the anemometer and alarm/display unit
  • Use of "common sense"...
    ...if the display indicates 0.0 (or close to it) for a long time or when wind conditions are anything other than dead-calm it would indicate a fault and readings/alarms should not be relied on.
