2.3.16Test
Transmissions
To ensure that the communication link with the central station is functioning properly,
the system can be programmed to send a test transmission signal on a regular basis.
The system can send a
Periodic Test Transmission Reporting Code
at the pro-
grammed
Test Transmission Time of Day
. The
Test Transmission Cycle
determines
the period of time between tests. When the test transmission cycle is programmed,
the system will send a test transmission the following day. This will indicate the begin-
ning of the new test transmission cycle to central station.
The end user can also generate a communicator test. If the
System Test Reporting
Code
is programmed, the system will send the signal when the System Test keypad
command is entered (see
[*] [6] User Functions
on page 27).

2.3.17Event Buffer
The system will store the last 128 events that have occurred on the system. Each event
will contain the time, date, and the event itself along with the zone number, access
code number or any other information pertaining to the event.
If the
Event Buffer Follows Swinger Shutdown
feature is enabled the event buffer
will not store events after the swinger shutdown level has been reached. This will pre-
vent the system from overwriting the entire buffer if a problem exists
(
see
2.3.18
Swinger Shutdown
on page 48
).
The event buffer can be uploaded to a computer for viewing through the DLS software.

2.3.18 Swinger
Shutdown
The swinger shutdown feature is designed to prevent a runaway communicator from
tying up the central station. Different limits can be programmed for
Zone Alarms
,
Zone Tampers
and
Maintenance
signals. After the system has communicated the
programmed number of transmissions for an event it will no longer report that event
until the swinger shutdown is reset.
For example, the swinger shutdown limit for Zone Alarms is set to [003]. The system
will not send more than 3 alarm signals for each zone with a swinger attribute until
the swinger shutdown is reset.
The Bell output will not be activated for alarms on zones that have exceeded the limit
of alarms set in the Swinger Shutdown counter.
Swinger Shutdown
will be reset when the system is armed, or every day at mid-
night. Once reset, the system will again communicate normally.

2.3.19Timebase
In cases of unstable AC power input you can use the internal crystal to keep a more
accurate timebase by enabling the
Timebase is Internal Crystal
option.
If the AC power input is very stable, it can be used as the timebase, by enabling the
Timebase is AC line
option.
