A
access level
There are three different levels of access to a base station:
Administrator, User, and Read-only. The User access level has a
configurable access profile; the Administrator decides which
functions that access level can carry out.
action
An action is the second part of a Task Manager task. It specifies
what the base station must do when the first part (the input)
becomes true.
active
Digital outputs are active when the base station pulls their voltage
low and current is flowing. Digital inputs are active when
external equipment is pulling them to ground. All base station
digital inputs and outputs are open collector.
ADC
Analog-to-Digital Converter. A device for converting an analog
signal to a digital signal that represents the same information.
Alarm log
The alarm log is a list of the last 50 alarms that the base station
generated. This list is stored in the base station. To view it, select
Monitor > Alarms > Reported Alarms.
Alarm Center
Alarm Center is a utility provided with the Service Kit that is able
to receive, store, and display alarms from any number of base
stations with dial-up connections. Participating base stations need
an Alarm Reporting license. Alarm Center also routes emailed
messages to the email server.
alarm notification
Alarm notification is the process by which the base station passes
on information about an alarm condition. It can notify alarms
over the air, over the line, via email, or to an Alarm Center. It
can also activate a digital output. If the Service Kit is logged on
to the base station, it is automatically notified of any alarms.
