OPCODE
This is the Operator Access Code (or Access Code Level 1 or 2) that 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
n/a
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
n/a
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
n/a
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 60 seconds.
FLOWHI, FLOWLO
High and Low limits set for Flow Fault. Note that Flow readings are normalized to 100%. All systems must
normalized at the installation stage.
FLOWLOG
If there is a change in flow greater or equal than this value and there is currently a flow fault, an entry in the log
is made of the new value.
SETFAN
Applicable to Low Pressure systems. The Default Fan Speed is 5 (Useable Range 3 to 10). Because of the
need to re-normalize the flow readings if the fan speed is changed, please note the following:
l
If the display [SETFAN n] flashes, this is the speed currently set
l
To Normalise 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 Normalisation 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.
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.
ADDRESS
This is the detector's RS485 address. The range is 0 to 30; a value of 31 disables RS485 communications.
The default setting is 31 (off). Note that if the display panel is used remotely, communication to it is by means
of this RS485 communications port, and the ADDRESS setting is not used.
Please note that this is not applicable on the standard product.
