Chapter 7: Programming
Online time out - When you are online with ISACC locally or remotely, the unit looks for
inactivity. This parameter allows you to set the amount of time, 1 - 255 minutes, that ISACC
will wait during inactivity before it terminates the online session, the default is 4 minutes. If
there is inactivity that meets this parameter, ISACC will disconnect and display the message
TIME OUT on your screen.
Acknowledge on carrier - When ISACC dials out in data mode, the unit will wait to
receive a carrier signal from a modem. This tells ISACC that a telephone connection has been
made. The acknowledge on carrier parameter allows you to program ISACC to self-acknowl-
edge an alarm when it receives the carrier signal. To acknowledge on carrier, type Y for yes. If
you do not want ISACC to acknowledge on carrier, type N for no. The default is Yes.
When used with the SHOW command, the SYSTEM keyword also displays the following
information in addition to the current values of the above parameters:
Alarm acknowledgment status - This parameter tells you if any alarms exist and, if so,
whether they have been acknowledged or not. To see which inputs are in alar m, type SHOW
ALARMS.
C program run status - This parameter will indicate if there is a C prog ram running or not.
Data log status - This line will indicate if the data logger is cur rently running.
Current temperature - ISACC has a temperature sensor on its circuit board. This parameter
will display the current board temperature, not air temperature, in degrees Fahrenheit and
degrees Celsius.
Battery level - This parameter displays the present voltage of the backup battery, rounded to
the nearest whole number.
AC power status - This parameter displays the status of the AC power. NOTE: You may use
power outage as a system alarm by controlling it through a C prog ram. See Chapter 8.
To display the cur rent system information and global parameter values, type show system at
an ISACC prompt:
