What to Do when TrueAlarm Troubles Occur

System Operators should do the following when these troubles occur.
• Almost Dirty Trouble. The system is programmed so that almost dirty sensors report as dirty. Contact your facilities management
personnel to report the trouble and schedule maintenance (cleaning) for the sensors.
• Dirty. This trouble means that maintenance should be scheduled for the sensor. Contact your facilities management personnel to
report the trouble and schedule maintenance (cleaning) for the sensors.
• Excessively Dirty. This trouble means the sensor is no longer compensating for dirt and dust. False alarms are possible in this
condition, and sensors should be cleaned as soon as possible. Contact your facilities management personnel to report the trouble,
and immediately schedule maintenance (cleaning) for the sensors.
