NTI SERVER ENVIRONMENT MONITORING SYSTEM

Alert Timing

Alert Delay: The alert delay is an amount of time the sensor must be in an alert condition before an alert is sent. This provides
some protection against false alarms. The Alert Delay value can be set for 0-999 seconds or minutes.
Example:
The maximum threshold of a temperature sensor is 90 F, and the temperature of the monitored area is fluctuating between 88 and
91 degrees:
(taken 1/ second)
The sensor is in an alert condition in Reading 3 but is back within the acceptable range in Reading 4. At Reading 5, the sensor is
in an alert condition again. Without the Alert Delay set, alerts will be sent for both Reading 3 and Reading 5. If the Alert Delay had
been set to 3 seconds, an alert would only be sent if the sensor had made three consecutive readings in an alert condition (since
readings are made every second). In this case, an alert will not be sent until Reading 9.
Notify Again: Specifies the amount of time before an alert message is repeated. The repeated alert can be set to occur from 1-
999 seconds, minutes, or hours.
Notify when return to normal: The user can also be notified when the sensor readings have returned to the normal range by
selecting the "Notify when return to normal" box for a sensor.
Automatically acknowledge alert when condition clears: Place a checkmark in this box to have alert notifications in the
summary page return to normal state automatically when sensor readings return to normal.
Alert Notifications
The alert can be configured to notify one or more users via e-mail, SNMP traps (V1), Syslog messages, or SMS alerts. The e-
mail subject line for e-mail notification can be customized for easy source identification. The alert can activate an audible siren, or
an alarm beacon. Alerts are also indicated on the "Int Alert" or "Ext Alert " LEDs on the front of the ENVIROMUX and in the WEB
interface.
Outputs
Each sensor can be associated with one of the connections labeled "Output Relays" (see page 23), and that connection can be
set to open or close the contacts of the relay either on alert, or when returning to normal.
command generated by the alert. In this way other devices can be controlled by sensor and tamper alerts.
be found in the wiring examples on pages 73 and 74.
Test Alerts
With all the configuration settings completed, each sensor and how the ENVIROMUX will react to an alert condition can be tested.
Press the Simulate Alert button at the bottom of the configuration page to test each of the notification methods configured. To
cancel the simulation, press the Clear button.
Note: A simulated alert will test all settings including any delay that has been configured (i.e. if a 2 minute delay is
configured, it will delay sending the email for 2 minutes)
To perform a test, the ENVIROMUX must be properly setup for a user to receive alert messages. Use the chart on the following
page to make sure the ENVIROMUX is setup properly.
