The platform provides a flexible set of alarm conditions that can be applied to any device or parameter across the system. These conditions help identify operational anomalies, device failures, or behavioral thresholds in real-time or over a period of time.

Users can select from the following alarm condition types when configuring alarms:

1. Threshold
   
   

2. Threshold with Duration
   
   

3. Counter
   
   

4. Counter with Duration
   
   

5. Flapping with Duration
   
   

Each condition type offers different capabilities suited for specific operational needs.

1. Threshold

Description

• This condition checks whether a selected parameter meets a predefined threshold.
  
  

• When the real-time data meets the specified operator condition against the threshold value, an alarm is triggered.
  
  

Supported Object Types

• All object types (Analog, Binary, Multistate)
  
  

Operator Types

• Analog:
  
  

• Greater than ( > )
  
  

• Greater than or equal to ( ≥ )
  
  

• Lesser than ( < )
  
  

• Lesser than or equal to ( ≤ )
  
  

• Equal to ( = )
  
  

• Binary / Multistate:
  
  

• Equal to the state
  
  

• Not equal to the state

Examples

• Analog:
  
  

• Room temperature > 25°C
  
  

• Light intensity > 80%
  
  

• Tab battery ≤ 20%
  
  

• Gateway network strength < 50%
  
  

• Binary:
  
  

• AC is in "trip" state
  
  

• Sensor is "occupied" during night hours
  
  

• Multistate:
  
  

• AC is in "heating" mode
  
  

2. Threshold with Duration

Description

• Extension of the Threshold condition with an added time duration.
  
  

• Alarm triggers only if the threshold condition is continuously met for the selected duration.
  
  

Time Options

• Minutes
  
  

• Hours
  
  

Examples

• Analog:
  
  

• Room temperature > 25°C for 30 minutes
  
  

• Light intensity > 80% for 1 hour
  
  

• Tab battery ≤ 20% for 15 minutes
  
  

• Gateway network strength < 50% for 10 minutes
  
  

• Binary:
  
  

• Pump is ON for more than 2 hours
  
  

• Sensor is "occupied" during night time for 30 minutes
  
  

• Multistate:
  
  

• AC is in "heating" mode for 20 minutes
  
  

3. Counter

Description

• Counts the number of times a selected condition is met.
  
  

• Triggers an alarm when the count reaches the defined threshold.
  
  

Applicable To

• All object types (Analog, Binary, Multistate)
  
  

Supported Operators

• Count = N
  
  

• Count > N
  
  

Required Fields

• Parameter
  
  

• Expected State
  
  

• Count to match
  
  

Examples

• AC powered ON 2000 times
  
  

• Pump powered ON 100 times
  
  

• Pump trip status occurred 5 times
  
  

• Light node rebooted 5 times
  
  

4. Counter with Duration

Description

• Same as the Counter condition but restricted to a specific duration.
  
  

• Useful for identifying patterns or anomalies over time.
  
  

Time Options

• Minutes
  
  

• Hours
  
  

• Days
  
  

• Months
  
  

Examples

• AC powered ON 2000 times in a month
  
  

• Pump powered ON >10 times in an hour
  
  

• Pump trip status occurred 5 times within 30 minutes
  
  

• Light node rebooted >5 times within 10 minutes
  
  

5. Flapping with Duration

Description

• Detects frequent back-and-forth switching (e.g., On-Off) between two states in a short duration.
  
  

• Typically used to detect device instability or faults.
  
  

Applicable To

• All object types (Analog, Binary, Multistate)
  
  

Required Inputs

• Parameter
  
  

• State 1 - Eg: On, Off or 30 C
  
  

• State 2 - Eg: On, Off or 30 C
  
  

• Count
  
  

• Duration (Minutes or Hours)
  
  

Note: This condition doesn’t require an operator. It inherently tracks state oscillation between two extremes.

Examples

• AC toggles between On and Off 3 times in 5 minutes
  
  

• Room temperature fluctuates between <15°C and >30°C once in 30 minutes

6. Multi-Condition Alarms (Using AND / OR Logic)

Multi-condition alarms allow you to create compound rules by combining two or more conditions using logical operators:

• AND: All conditions must be satisfied for the alarm to trigger.
  
  

• OR: At least one condition must be satisfied for the alarm to trigger.
  
  

This is useful when monitoring systems that may exhibit abnormal behavior under a combination of events or when multiple parameters contribute to a fault state.

Supported Logic

• You can mix different condition types (e.g., Threshold + Counter, Threshold with Duration + Flapping).

• You can have multiple conditions of the same type for different parameters (Threshold)

Examples

Example 1: AND Condition

Trigger an alarm only if all of the following are true:

• Room temperature > 28°C for 20 minutes
  
  

• AC is in "ON" mode

Interpretation: This could be used to detect if the AC is ineffective and not cooling sufficiently.

Use AND for specific, tightly controlled fault conditions.

---

Example 2: OR Condition

Trigger an alarm if any one of the following is true:

• Room Temperature < 18 C
  
  

• AC Alarm parameter is Active

• AC is off
  
  

Interpretation: This helps detect any form of anomaly in a Server room AC
