Alarms Service Process
- Alarms service is responsible for monitoring site's readings displayed in Current Readings page and firing alarms when readings exceed threshold value configured by user
- Readings and alarms are configured by authorized users from 'Readings & Alarms' tab in Edit Site page, including:
- Alarms Threshold (Minimum, Maximum)
- Notifications Types (Email, SMS, Mobile)
- Periodicity Time (Rise Time, Resend (Email, SMS, Mobile), Back to Normal)
- When alarm is fired, it appears in Current Readings page and alarm notifications are sent to authorized users
- When alarm is active for along time, a Reminder Notification according to Resend Time is sent with all active alarms
- When alarm is closed and back to normal, Notification according to Back to Normal Time is sent with all active alarms
- In case of highly repeated alarms for specific times at specific period, alarm notification is sent immediately
- As long as alarm is in high repetition mode, it's still sent only in reminder notification with all other alarms
- High repetition mode ends when alarm is back stable again (raised, back to normal) after total period of high repetition
(Total Period of High Repetition = Repeated Times * High Repetition Interval)
- You can suspend/pause alarms from sending notifications for specific time in Current Alarms page
- You can also monitor alarms information from Alarms History and Alarms Statistics pages
- You can apply alarms severity levels from Alarms Severity Default Configuration page
Custom Alarms Conditions:
- Ambient Temperature Alarms
- There is safety margin ±1 for minimum and maximum thresholds
- For example, temperature thresholds are (Min= 15, max= 30)
- Alarm is raised when temperature is (< 14) and back to normal when it's (> 16)
- Alarm is raised when temperature is (> 31) and back to normal when it's (< 29)
- Battery Level
- Alarm threshold of battery level is <= 20
- Alarm is raised when battery level is <= 20
- Alarm is back to normal and closed when battery level is >= 45
Example of High Repetition Mode:
- Enable Notification (Email, SMS)
- Edit Rise (Rise Time Periodicity = 0, Back to Normal = 0, Reminder = 80)
- Consider high repetition (times = 3, interval = 20 mins), then (total high repetition period = 3 * 20 = 60 mins).
- This alarm is raised and alarm notifications (Email & SMS) are sent according to rise time.
- At 1st time, before 20 mins:
- Alarm is back to normal, then alarm notifications are sent (Email & SMS)
- Alarm is raised, then alarm notifications are sent (Email & SMS)
- At 2nd time, and before 20 mins:
- Alarm is back to normal again, then another alarm notifications are sent (Email & SMS)
- Alarm is raised, then alarm notifications are sent (Email & SMS)
- At 3rd time, before 20 mins:
- Alarm is back to normal again, then alarm notifications are sent (Email & SMS)
- Alarm is raised, then this alarm enters High Repetition Mode and alarms notifications are sent immediately with (current status, repetition times =3, and start time)
- At 4th time, before 60 mins:
- Even if alarm is still raised or back to normal, alarm notifications are NOT sent immediately.
- In reminder notification after 80 mins, this alarm is sent again with (current status, repetition times, and start time)
- High repetition mode is ended after 60 mins for this alarm in stable mode (Raised/Back to Normal).
