Concept
Fire Detection System Alarm Categories
In a fire detection system, there are different types of alarms, faults, maintenance alerts, tests, and disablements. Various causes generate these alarms and changes in device states.
All alarms from the FDP server are categorized as system alarms in EcoStruxure Fire Operation. The alarms belong to one of the system alarm categories in EcoStruxure Fire Operation.
Within each category, there are several types of system alarms. For more information, see Fire Detection System Alarms .
Note that the alarm mode set in Fire Expert affects which category of alarm and alarm that is triggered. For more information, see Alarms and states .
Fire Alarms
Fire alarms are generated when fires are detected by devices in the fire detection system and one of certain alarm modes are active. For more information, see Alarms and states .
|
System Alarm Id |
Description |
|
Fire |
A fire is detected by detectors or initiated by for example a manual call point or an input unit. |
|
Local fire |
A fire is detected, but the alarm is not transmitted to the fire alarm router. Local fire alarms are generated when the alarm mode is set to Local alarm. |
|
Delayed fire |
A fire is detected, but the alarm delay function is configured. It gives the operator the option to acknowledge an alarm and get more time to investigate the cause of the alarm and take appropriate action. |
Faults and Maintenances
Faults are related to, for example, issues with devices or connections in the fire detection system. Maintenance alerts are related to, for example, the configuration or the drift limit of the fire detection system.
For more information, see Faults and Maintenance Alerts .
Test Alarms
Test alarms are generated by a user when a zone is in test mode. For more information, see Alarms and states .
|
System Alarm Id |
Description |
|
Test fire |
A fire alarm is generated while the zone is in test mode. |
|
Test technical alarm |
A technical alarm is generated while the zone is in test mode. |
|
Test pre-alarm |
A pre-alarm is generated while the zone is in test mode. |
|
Test fault |
A fault is generated while the zone is in test mode. |
|
Test maintenance |
A maintenance alert is generated while the zone is in test mode. |
Pre-alarms
A pre-alarm is generated when certain alarm modes are set. Pre-alarms give the operator time to investigate a potential fire before an actual fire alarm is generated. For more information, see Alarms and states .
|
System Alarm Id |
Description |
|
Pre-alarm |
Generated when the alarm mode is either Pre-alarm or Coincidence. If the mode is Pre-alarm, only pre-alarms are generated. If the mode is Coincidence, the first detector generates a pre-alarm until other conditions are fulfilled. Those conditions depend on the configuration. |
Technical
Technical alarms are generated due to technical issues in the fire detection system or integrated solutions. Technical alarms can be generated in any alarm mode. For more information, see Alarms and states .
|
System Alarm Id |
Description |
|
Technical alarm |
Generated when a technical issue in the fire detection configuration occurs. These alarms are often related to devices in external systems that are important to the fire detection system. Initiated by inputs configured as Technical alarm input or Silent technical alarm input. |
Disablement
Disablement alarms are generated when certain objects are disabled by users. Disablement alarms can be generated in any alarm mode. For more information, see Alarms and states .
|
System Alarm Id |
Description |
|
Disablement |
Generated when a device, zone, or other object is disabled in an FDP panel or the panels that are visible to it. |
None
This is the default category. It is used on system alarms that are not related to fire detection.
