The automatic log-off feature mentioned above is automatically disabled for the TL1
port. See the description of the TL1 software option.

1.4.8 System Alarm Reporting: This method is designed to satisfy the requirements of
maintenance personnel. In this method, the system as a whole is programmed to report alarm
conditions to a specific user (or a sequence of users if the primary user cannot be reached) if
an alarm occurs on any channel programmed for System Alarm Reporting. When an alarm
condition occurs on a channel configured for System Alarm Reporting, the system attempts
alarm notification by either dialing the first user in the predetermined calling sequence or by
Emailing the first user. If this user is reached, the alarm report is given in the mode (pager,
modem, or Email) configured for the specified user. System Alarm Reporting is considered
successful when:
a) the system connects with a modem or an Email notification is sent to a valid Email
address,
or
b) the user issues an ACKnowledgement after receiving the alarm notification.
One of the above options is selected during initial system programming. If alarm reporting is
not successful, the system continues, calling or Emailing the next specified user. If each user
is called or Emailed and an alarm report is not successfully issued, the system waits the
specified retry time interval and then repeats the process.
1.4.9 Individual User Alarm Reports: This method provides each user with the capability of
receiving four different reports, with the first three listed pertaining only to channels that the
user has selected. These reports can be delivered by the system to the user through a pager
(via modem), remote terminal (via modem), or Email (via Ethernet). These reports are:
(A) Occurred Alarm Reports: a report of any new alarms that have occurred on the user’s
channels.
(B) Retired Alarm Reports: a report of any alarms that have cleared on the user’s channels.
(C) Persistent Alarm Reports: a periodic report of any alarms that still exist on the user’s
channels.
(D) Daily Report: The user specifies a standard system command or one of the
programmable commands which is issued as this report. The daily report is given at a
specific time each day.
1.4.10 Alarm Cut-Off (ACO): The alarm cut-off feature enables silencing an external alarm by de-
energizing the system alarm relay connected to it. All relays configured for alarm cut-off are
de-energized by issuing a command. Another command can be issued to cancel alarm cut-off.
This feature operates by masking (preventing) existing analog and binary alarm conditions
from affecting a relay's control program. These alarms are considered cancelled and no longer
figure into the evaluation of the relay's control program. Any cancelled alarm that clears and
then turns in again DOES have the ability to affect a relay's operation.
A relay channel attribute termed the "Cycle Frequency" is designed for use with external alarm
circuitry that has its own alarm cut-off. More specifically, this is for applications where an
external ACO has silenced an audible alarm but it is desired to have it turn in again after a
preset amount of time. The cycle frequency allows energized system relays to temporarily turn
off for 15 seconds, thus providing another "open to close" transition to turn in the audible alarm
again.
1.4.11 Information Pages: Three user programmable information pages (or screens) can be entered
in the system. These information pages can be viewed by any user. These pages can serve
as a note pad or location of instructions for users.
1.4.12 Status Pages: Sixteen user programmable status pages (or screens) can be formatted in the
system. These pages permit the displaying of scan information derived from separate
