Overview
Sigicom devices support one trigger threshold level at a time. However, you can still work with multiple alarm levels, such as green, amber, and red thresholds, by combining the device trigger setting with message rules in INFRA Net.
The recommended setup is to configure the device with the lowest required trigger level and then use INFRA Net message rules to manage the additional notification levels.
Recommended Configuration
Set the trigger level on the device to the lowest desired threshold value.
For example, if the required vibration thresholds are:
Green: 0.2 mm/s
Amber: 0.4 mm/s
Red: 0.6 mm/s
the device should be configured with a trigger level of 0.2 mm/s.
The remaining threshold levels should then be managed in INFRA Net using message rules.
Example Message Rules in INFRA Net
Create separate message rules for each required notification level:
Alarm level | Message rule name | Trigger type | Threshold value |
|---|---|---|---|
Green | Green Threshold Exceeded | Trigger Values | Value configured on the device, for example 0.2 mm/s |
Amber | Amber Threshold Exceeded | Absolute Values | 0.4 mm/s |
Red | Red Threshold Exceeded | Absolute Values | 0.6 mm/s |
In this setup, the device sends data when the lowest threshold is exceeded. INFRA Net then evaluates the configured message rules and determines which notifications should be sent.
Important Notification Behavior
Each message rule in INFRA Net is processed individually.
This means that if the measured value exceeds a higher threshold, such as 0.6 mm/s, all matching rules may be triggered at the same time. In this example, the green, amber, and red rules would all be processed because the value exceeds all three configured thresholds.
As a result, recipients who are included in all three message rules may receive multiple notifications for the same event.
Recommended Recipient Setup
To avoid sending multiple notifications about the same event to the same person, configure different recipients for each alert level.
For example:
Alarm level | Suggested recipient |
|---|---|
Green alert | Site technician |
Amber alert | Project technician |
Red alert | Project admin or project lead |
This approach ensures that each stakeholder receives the notifications most relevant to their role, while reducing duplicate messages.
Summary
When using multiple trigger thresholds:
Configure the device with the lowest desired trigger level.
Create separate message rules in INFRA Net for each alarm level.
Use Trigger Values for the lowest threshold configured on the device.
Use Absolute Values for higher thresholds.
Adjust recipient lists to avoid duplicate notifications.
This setup allows you to manage multiple notification levels in INFRA Net, even though the device itself supports only one trigger threshold at a time.
