Type
This tells the dialer how to treat this I/O Channel. Each dialer channel can be programmed to
operate independent of the others. Changing the Type of a dialer channel is dependent on the
hardware module that is currently installed in this dialer channel.
Based on the current type of module being programmed, only applicable values will be editable on
the form. For example, if the current type of module is an Input Type, the setting for changing the
Current Output State will not be shown. Also, if the current type of module is a Digital Type
(Opened/Closed), the settings for Analog Channel Types (Some Variable Level) won’t be shown,
and vise versa.
Spare Channel Type
This channel input is ignored by the dialer. All channels that are currently being unused should be
programmed as Spare.
Input Types
Input Types are used for monitoring current situations out in the field. They can be used in
different ways. One way is to only report the current condition in the field and not call out on an
abnormal/fault condition (Alarm Configuration = Status). Another way is to use the channel is
as an alarm reporting channel to cause alarm call outs when a fault condition occurs (Alarm
Configuration = Call On Alarm). There is also a setting for these channels to call out when an
alarm condition occurs and when it clears (Alarm Configuration = Call/Return).
Whenever an Input Type is programmed to Call on an alarm condition and such a condition
occurs, this channel will try to report the alarm condition that has occurred to the phone numbers
that are in its Telephone List. The numbers that are in this list will be called in order until this
channel alarm becomes acknowledged.
The following are the programmable channel Input Types:
Normally Open Digital Input
These channel inputs are reported as either Open or Closed. The normal condition is the Open
condition and the fault condition is the Closed condition. For example, this can be used to
monitor a Pump Failure Indicator, High/Low level switch, etc.
Normally Closed Digital Input
These channel inputs are reported as either Open or Closed. The normal condition is the Closed
condition and the fault condition is the Open condition. For example, this can be used to monitor
an intrusion alarm, system normal indicator, etc.
Analog Input
These channel inputs are reported as a level value. The normal condition is when the current
level value is between the High SetPoint and Low SetPoint. The fault condition is when the
level value is either above the High SetPoint or below the Low SetPoint. For example, this can
be used to monitor a tank level, the current flow reading from a flow meter, etc.
To change the value of the Setpoint, click on the button next to the value.
