Failed To Sound System Fail Federal Commander Digital System Note: FOB, Rear Input and Alert Button status points may be renamed (Reference Intercom Configuration-Input Options). For data items marked Latched, once detected will remain latched (pass state) in the RTU's memory until a Master Reset, Quiet Test or Activation command is sent. This will allow the units to be polled at a later time following an activation to obtain activation status. It is very important for the operator to understand that all status data conditions are current as of the last poll and may not represent the present status conditions. Failed To Sound The “Failed to Sound” status point fails when one of the following conditions occurs: 1. Last Function Base and Last Function RTU do not agree 2. Last Function Base and Last Function RTU times disagree by more than 90 minutes 3. Audio Fail “Failed to Sound” reporting may be enabled or disabled by the setting of the “Failed to Sound” field on the System Setup screen. If enabled a Failed to Sound fault may occur when the site is activated locally or non-digital activation (duotone, DTMF, etc). Failed to Sound may also occur if unit is activated by a remote digital station and Commander is unable to eavesdrop the remote station. System Fail The “System Fail” status point fails when the conditions defined on the System Fail setup dialog Alarm Filter is met for this siren site. Note: An individual site System Fail alarm does not imply a general System Fail alarm. A general System Fail alarm may require multiple site failures as defined on the System Fail setup dialog. Alarm (Automatic) Reporting Indicates if RTU auto reporting is enabled or disabled. If enabled, auto reporting occurs when any of the above status conditions changes state. If disabled, status is sent only when polled. Power Fail Reporting Indicates if RTU power fail reporting is enabled or disabled. If enabled, power fail reporting occurs when AC Power changes state. If disabled, status is sent only when polled. Function And Cancel Counters Contains the number of activation and cancel codes received by this RTU. These fields are cleared (set to zero) by the Clear Counters command from the send menu of Configure RTU Parameters. Activate Site These eight push buttons send an activation command to the selected RTU. Function Running Displays the function running at the time of the last poll. If no function is running, STANDBY is 162 RTU

displayed. Last Function RTU Federal Commander Digital System Displays the last function sounded by this RTU. The status of latched sensors (current, rotation, pressure, failed to sound) reflects the conditions of the siren as a result of the Last Function. If not function has sounded since a Master Reset, Standby will be displayed. Last Function Base Displays the last function activated by the base. Note: If the Last Function base is not „Standby‟, a Failed to Sound alarm will be asserted if one of the following conditions is met: 3. Last Function Base and Last Function RTU do not agree 4. The times disagree by more than 90 minutes RTU Time During each poll, the RTU‟s time clock is synchronized with the base computer or SS2000D. The current setting of the RTU‟s embedded clock is reported back to the base before this update occurs. This allows the system administrator to monitor the system time clock synchronization. The RTU Time should normally be within a few minutes of the base station's time during the last poll. If not, a possible synchronization problem exists. It is important to maintain system time clock synchronization. RTU‟s that are out of the time sync window (90 minutes) will not sound. Anytime the time synchronization becomes more than 45 minutes out of agreement, a Sync Fail alarm will be logged. 163 RTU

Last Function RTU<br />

<strong>Federal</strong> <strong>Commander</strong> <strong>Digital</strong> <strong>System</strong><br />

Displays the last function sounded by this RTU. The status of latched sensors (current, rotation,<br />

pressure, failed to sound) reflects the conditions of the siren as a result of the Last Function. If<br />

not function has sounded since a Master Reset, Standby will be displayed.<br />

Last Function Base<br />

Displays the last function activated by the base.<br />

Note: If the Last Function base is not „Standby‟, a Failed to Sound alarm will be asserted if one of<br />

the following conditions is met:<br />

3. Last Function Base and Last Function RTU do not agree<br />

4. The times disagree by more than 90 minutes<br />

RTU Time<br />

During each poll, the RTU‟s time clock is synchronized with the base computer or SS2000D. The<br />

current setting of the RTU‟s embedded clock is reported back to the base before this update<br />

occurs. This allows the system administrator to monitor the system time clock synchronization.<br />

The RTU Time should normally be within a few minutes of the base station's time during the last<br />

poll. If not, a possible synchronization problem exists. It is important to maintain system time<br />

clock synchronization. RTU‟s that are out of the time sync window (90 minutes) will not sound.<br />

Anytime the time synchronization becomes more than 45 minutes out of agreement, a Sync Fail<br />

alarm will be logged.<br />
