OPCODE
This code (or Access Code Level 1 or 2) must be entered to enable ISOLATE, SOUNDER SILENCE and RESET buttons. The default
value is 0. It may be changed within the range 0 to 999, but 260 and 693 should be avoided as these are reserved for Level 1 and
2 access codes. A zero value removes the need to enter an Access Code.
ENDSCTR
The default value is 4, 6, 8 or 15 depending on the unit type (e.g. FireTracer 4, 6, 8 or 15). If fewer sectors are to be sampled,
ENDSCTR should be set accordingly and the unused sample inlets should be blanked off. Those used should be a contiguous set
beginning from the first inlet.
DENSLOG
If there is a change in density greater or equal than this value, an entry in the log is made of the new value.
TRCLTCH (not on FT1), ALTLTCH, ACTLTCH, F1LTCH, F2LTCH
Defines whether Alarm events are to be latched. If not latched, the Alarm condition will clear as soon as the cause disappears. If
latched, the system must be reset to clear the Alarms. Note that the ACCEPT or SOUNDER SILENCE buttons may be used to stop
the internal sounder, and the ISOLATE button may be used to disable all Alarm relays. The default is 1 (Latching)
FLTLTCH
A FAULT condition will exist if any specific fault within the system is detected. It will be accompanied by closure of the Normally
Closed contacts of the FAULT relay, and illumination of the GENERAL FAULT indicator. If it is made Latching, the relay contacts
and indication will remain even after the originating Fault condition has ceased, and the system must be reset to clear FAULT. The
default is 1 (latching)
TRCRLY (not on FT1)
Optionally, the ALERT relay can be re-assigned to activate when the unit goes into TRACE mode. To do this set to 1. The default
is 0.
REFCOMP, REFDEL
When referencing is used, REFCOMP is the proportion of the Reference Density Value that is used to back off the Sample Density.
The product is subject to a maximum of 0.05% back-off value. It is applied progressively over time, reaching its final value after
the Reference Delay, REFDEL
REFADDR
When Referencing is used, this is the RS485 (ICAMnet) address of the reference detector.
FLOWDEL
Flow Fault Delay. The time period in seconds for which a Flow Fault must be sustained before registering as a fault. The default is
5 seconds. The range is 1 to 60s.
FLOWHI, FLOWLO
High and Low limits set for Flow Fault. Note that Flow readings are normalized to 100%. Low pressure (Wide bore) systems must
be calibrated at the installation stage so that the unit can “learn” what normal flow measurements are. Default FLOWHI is 150%,
except for the FT15 which is 200%. The range is 0 to 200%. Default FLOWLO is 50%. The range is 0 to 200%.
FLOWLOG
If there is a change in flow greater or equal than this value, an entry in the log is made of the new value.
SETFAN
Applicable to Low Pressure (Wide bore) systems. The Default Fan Speed is 5 (Useable Range 2 to 10). Because of the need to re-
normalize the flow readings if the fan speed is changed, please note the following:
1. If the display [SETFAN n] flashes, this is the speed currently set
2. To Calibrate the Flow readings, go to SETFAN press ENTER when the display is flashing (i.e. the speed is set to current
value). Entering a new speed will not automatically initiate a re-calibration of flow measurements, and the flow readings may
not be normalized. This must be initiated by returning to SETFAN and pressing ENTER. The Flow Calibration sequence will
last about six minutes, during which time, the display will report progress. This operation must be done for new installations,
or if the sample tube arrangement has been modified, or if the fan speed is changed. But note that if calibration has been
done before at a particular fan speed setting, those calibration values will be retrieved and used.
STANDBY
Standby supply (optional Battery Supply). The default is 0 (no Batteries fitted). If batteries are to be fitted, STANDBY must be set
to 1 to enable the internal charger.
PWRDEL
A.C power fail delay time (seconds). If the a.c. power supply fails for less than this time, it will not show as MAINS FAULT. It is
assumed that during this time, the unit will be running from a standby battery supply. The default setting is 10 seconds. The
range is 1 to 1000 seconds
BUZZER
The internal sounder may be enabled or disabled on a permanent basis. The default is 1 (enabled). The sounder (if enabled)
accompanies all ALARM conditions.
BEACON
The integral Beacon may be enabled or disabled on a permanent basis. The default is 1 (enabled). The beacon (if enabled)
accompanies all ALARM conditions.
