Dust separator condition
Display - Address 001-127: The value given at this function is the efficiency
rating of the dust separator (filter) in the detector. A new cartridge 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 (filter) cartridge is missing or improperly fitted, the display will
read Separator change. Installing a new cartridge will automatically reset this
figure to 100%.
Relay tests
Test - Address 000-127: 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
The test steps to the next test on the list when you press the ENTER key.
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.
Caution: Operating the Alarm or fault relays will physically activate and switch
the contacts. Ensure that the receiving Fire Panel is in test/maintenance mode
before initiating this test.
Watchdog trip count
Display: 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.
Event log
An event is defined as operation of any of the front panel controls (when
enabled), a signal received from a remote source (e.g., the command module or
PC), a detector level exceeding the Aux, Pre-Alarm, Fire 1 or Fire 2 thresholds or
certain commands sent from the remote software or SenseNET. The event log
will also store items such as day and night start times, demonstration mode,
power fault, detector fault, etc. The detector keeps a log of the last 200 events for
reference purposes.
The event log can be downloaded using a PC that has the remote software
installed and is connected to the detector’s RS-232 port using a serial cable.
