3.4.19 Device Text (Alpha - Address 000-127)
Setup menu > Detector
This is the default text string displayed on the Standard Detector or Command
Module LCD display. If desired, this can be altered to any 16 character alphanumeric
identification. Thus, for example, the name of the area being protected, or the name
of the person responsible for fire safety could be entered. The default device text is
Stratos-HSSD 2 and the firmware revision level for the Standard Detector, and
Command Module and the firmware revision level for the Command Module.
3.4.20 Reference device (Numeric - Address 001-127)
Setup menu > Reference
Any detector on the loop may use another detector as a fresh air reference. When
entering the Reference submenu the user is prompted to first select the address of
the detector which will be using the reference, and is then forwarded to this option.
To set a detector as a reference detector, enter its address as set by its internal DIP
switch into this function.
3.4.21 Reference enable (Yes/No - Address 001-127)
Setup menu > Reference
Setting this function to Yes enables the reference for the detector, if one has previously
been allocated in Reference device (1-127) (see section 3.4.20, ‘Reference
device’).
3.4.22 Reference level (Numeric - Address 001-127)
Setup menu > Reference
The value set with this function is the percentage reference signal subtracted from the
detector’s signal, if a reference device has been allocated.
3.4.23 Back-off (Numeric - Address 001-127)
Setup menu > Reference
This value is the delay time (in seconds) between a build up of pollution being seen by
the reference (if used) and the pollution being seen by the detector.
3.4.24 Reset, Test & Isolate button enable/disable
(Yes/No - Detectors 000-127)
Setup menu > Front panel
The front panel buttons may be enabled or disabled individually for the Command
Module or Standard Detectors by setting these functions to Yes or No.
3.4.25 Power save enable (Yes/No - Addresses 001-127)
Setup menu > Power checks
This function allows the detector to minimise electrical power consumption when
operating from stand-by batteries. If enabled, upon mains supply failure the aspirator
will reduce speed to minimum, regardless of the user-defined value. This function may
be disabled if the minimum aspirator speed increases transport time unacceptably. (See
Section 3.4.28, “Aspirator speed”).
When in this condition, any smoke reading above 3 bar graph segments on the
detector will automatically remove this condition.
This function has no effect on the Command Module.
