3.4.45 Detector read (Display - Address 001-127)Diagnostic menuThis function displays five values as shown: 009.47%086 091 087 091The top value is the detector’s current smoke level reading as a percentage of thefull-scale value, and the bottom four readings are the current flow rates on each pipe asa percentage of the maximum possible flow rate.3.4.46 Loop errors (Display)Diagnostic menuThis displays the percentage of loop errors in messages addressed to the detectoror Command Module from the detector loop, along with a count of the number ofreceived messages since the last message was received on port 1 and port 2 of theRS485 bus.3.4.47 Dust separator condition (Display - Address 001-127)Diagnostic menuNB ☞The value given at this function is the efficiency rating of the dust separator element inthe detector. A new element will give the reading Separator 100.0% in this function.When the efficiency has decreased to 80%, the Fault indicator LED will illuminate andthe text display will show Separator renew.If the separator is missing or improperly fitted the display will readSeparator change.Fitting a new element will automatically reset this figure to 100%.See section 10, “Maintenance” for further details.3.4.48 Relay tests (Test - Address 000-127)Diagnostic menuThis tests the connection of the Command Module or detector to an alarm panel byoperating the alarm or fault relay currently selected. Assuming proper connection,this should give appropriate indications on the fire panel. The test runs through thesequence Aux –> Pre-Alarm + Fault –> Fire 1 + Fault –> Fire 2 + Fault –> Fault, steppingto the next test on the list when is pressed. Although the relevant relays areactivated at each stage, the associated lights on the front panel are not illuminated orrecorded in the event log.3.4.49 Watchdog trip count (Display)Diagnostic menuThe watchdog is a circuit built into the controller that restarts the controller in the eventof a failure to function properly. This could be as a result of electrical spikes. This countshows the number of interruptions found. The details of each problem can be foundin the event log.See 3.4.43, “Event log” and section 7 for further details.Page 23Stratos HSSD-2 • INSTALLER’S HANDBOOK • Iss. 10© AirSense Technology. 2009
