3.4.45 Detector read (Display - Address 001-127)
Diagnostic menu
This function displays five values as shown: 009.47%
086 091 087 091
The top value is the detector’s current smoke level reading as a percentage of the
full-scale value, and the bottom four readings are the current flow rates on each pipe as
a percentage of the maximum possible flow rate.
3.4.46 Loop errors (Display)
Diagnostic menu
This displays the percentage of loop errors in messages addressed to the detector
or Command Module from the detector loop, along with a count of the number of
received messages since the last message was received on port 1 and port 2 of the
RS485 bus.
3.4.47 Dust separator condition (Display - Address 001-127)
Diagnostic menu
The value given at this function is the efficiency rating of the dust separator element in
the 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 and
the text display will show Separator renew.
If the separator is missing or improperly fitted the display will read
Separator 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 menu
This tests the connection of the Command Module or detector to an alarm panel by
operating the alarm or fault relay currently selected. Assuming proper connection,
this should give appropriate indications on the fire panel. The test runs through the
sequence Aux –> Pre-Alarm + Fault –> Fire 1 + Fault –> Fire 2 + Fault –> Fault, stepping
to the next test on the list when <ENTER> is pressed. Although the relevant relays are
activated at each stage, the associated lights on the front panel are not illuminated or
recorded in the event log.
3.4.49 Watchdog trip count (Display)
Diagnostic menu
The watchdog is a circuit built into the controller that restarts the controller in the event
of a failure to function properly. This could be as a result of electrical spikes. This count
shows the number of interruptions found. The details of each problem can be found
in the event log.
See 3.4.43, “Event log” and section 7 for further details.
