2.3.17 Event 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 prevent the system from overwriting the entire buffer if a problem exists (see

2.3.18 Swinger Shutdown on page 50).

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 communi-

cated 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 sys-

tem 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.

2.3.19 Timebase 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.

2.3.20 Factory

Default

On occasion it may be necessary to return the NT9010 system to factory default set-

tings. You can either default all the programming in the NT9010 (including device

serial numbers), or you can default only certain sections of the programming.

Performing a Software Default of the NT9010 System

This procedure will return NT9010 system programming, except the reporting

codes, to the factory default settings.
