Alarm Delay: The amount of time the F3400/F1000 waits to send an alert after an alarm

condition is detected. The F3400/F1000 uses this same time delay to report a return to normal

after the alarm condition clears. The alarm delay is active for all input types except Not

Configured.

Example:

An input is configured as a digital NO, labeled “CRAC UNIT ALARM” and has an alarm

delay of 10 seconds. When the CRAC unit alarms, it closes the contact to the F3400/F1000.

If the CRAC unit returns to normal and opens the contact to the F3400/F1000 within the 10

second alarm delay, no alarm is generated in the F3400/F1000. If the CRAC unit remains in

alarm for 10 seconds or more, the F3400/F1000 records the alarm and generates notification

per the input settings. If the CRAC unit returns to normal and alarms within the 10 second

alarm delay, the F3400/F1000 does not record it as a return to normal. Once the CRAC unit

returns to normal for the 10 second alarm delay, the F3400/F1000 records a return to normal

and generators notification per the F3400/F1000 settings.

Hysteresis: The number that designates the amount an input reading must sway from its preset

alarm reading before it is classified as returned to normal. The Hysteresis provides a deadband

around the limit settings to prevent several alarms and return to normal alarms when the input is

the same as a limit setting.

The Hysteresis applies when the input type is Analog 4-20mA or thermistor and is active for

High Limit 1, High Limit 2, Low Limit 1 and Low Limit 2.

Example:

A temperature sensor alarms when it reaches its High Limit 1 of 80°F. If Hysteresis is set at

four, the sensor must register less than 76°F before the F3400/F1000 reports it as returned to

normal. In another example, a humidity sensor alarms when it reaches its Low Limit 2 of

30% RH. If the Hysteresis is set at five, the humidity must register more than 35% before the

F3400/F1000 reports it as returned to normal.

Relay Activate: Used to assign a Threshold change to analog inputs, or Digital Alarm

generated by this input to a specific relay. To select the relay, check the relay box. This feature

can be set to activate on a High 2/Low 2 threshold for analog points, in the Relay configuration

Dial Out Notification: The list of up to 4 pager numbers to which the F3400/F1000 sends

alarm notification. The numbers correspond to phone numbers configured from the Configure

Phone Number links at the bottom of the Modem Configuration page. Separate each ID number

with a comma. Enter zero to disable. The F3400/F1000 will dial the lowest number listed

regardless of the order the numbers are listed. See 4.5.1, “Configure Phone Numbers” on

Example:

If the Alarm dial out string is set to “3, 5, 1, 0”, the F3400/F1000 will dial Pager #1, Pager #3

and then Pager #5 when an alarm occurs. Pager notification will be sent when an input

alarms (high limit 2, high limit 1, low limit 1, low limit 2 is exceeded or the digital input is in

alarm). An option on the Pager Configuration page determines if the F3400/F1000 will send

a page when an input returns to normal.
