Definition: The operation and effectiveness of the detector relative to the area of fire origin.
NFIRS 5.0 relational edit validation rules are provided to ensure NFIRS data is consistent and correct for the fire/reporting concepts that are being modeled. Relational edits determine relationships between multiple fields / elements. These are the rules for ‘Detector Operation’.
|Relational Edit Rule 75||If the detector operated, did it alert occupants?.|
|Relational Edit Rule 76||If the detector failed, how did it fail?.|
Here are the NFIRS codes for the ‘Detector Operation’ element, including any “other” values in case none of the preselected choices match:
|Fire Too Small To Activate Detector||1|
|Detector Failed To Operate||3|
|Element Type||Coded Field - The coded field relating to an entry in the code table. Most coded fields allow for Plus+ One codes. For these fields the expected length of the coded entry is depicted as (National length OR Plus+ One length). Only fields with this notation in the expected length column allow for Plus+ One definitions. If the user has not provided information, an empty field should be transmitted.|
