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.
