F4 – Faults
Gem-5 User’s Manual 227
High Count Time: See F4 – Out of Service Causes screen (on page 141).
Decision Threshold: This is applied when Methodology is “Bayesian” and for
count time used the Detection Threshold is greater than Alarm Activity. See
Bayesian Supplementary Manual for more details.
Due for Recalibration: The recalibration date/time or number of days set in the
F4 – Out of Service Causes screen (on page 141) screen is passed. This is
labelled as a “Calib Due” column in Service History Page 3 and its associated
Printout.
Conditional Service Elapsed / Conditional Service OK: When the number of
days specified in the F4 – Out of Service Causes screen (on page 141) screen (see
Conditional Service Allowed) for placement of detection zone(s) in conditional
service has been exceeded the former will appear; otherwise the latter will be
shown. This is hidden if the Allow Conditional Service setting in the F1 –
Model Selection screen is set to “NO”or if Conditional Service Allowed is set to
0 days. The underlying fault(s) should be corrected and then use F5, F4 on the
F4 – Faults screen to clear the error condition. If absolutely necessary, the
detection zone(s) can be placed in conditional service for another time period by
pressing F5 once (Place All Zones In Normal Service) and F4 once (Clear All
Faults) and then F1 (Place Detector (or Sum Zone) In Conditional Service) for
each detection zone individually as required.
When applicable, the Faults screen also indicates Carrier Board OK/Fault, Sensor
Board OK/Fault, Auxiliary Sensor Board OK/Fault, Background Update
OK/Fault, Alarm Test OK/Due and Temperature OK/HOT (i.e. Carrier Board
temperature status) as other possible causes for an Out of Service condition.
Other possible faults are model and settings dependent such as Database
OK/Fault, DBR Badge Reader, Suggest Krypton / Normal mode, Voltages, Hot
Side Barrier OK/Fault and Cold Side Barrier OK/Fault and +12 Volt OK / Fault.
Table 14 shows the general layout of the status area of the Faults screen (note
that not all the items listed are always displayed – depending on the unit
configuration and setup).
