ThisdisplayislocatedontheStratos-HSSD®Masterunit(andremotemimic

detector units connected to the Master detector. If Slave detectors are
installed, the detector/area being given on the display is indicated by a
flashingYellowlightbelowthebargraph,(thislightwillflashfortenseconds

show the condition of Air Flow, Detector, Power, Dust Separator and any

It is important to understand that if any of the yellow Fault lamps are

This alarm level is fixed at bargraph level 8. If the red FIRE light operates,

usually time to commence evacuation procedures. Other actions in the
event of the FIRE lamp operating will depend upon the application, but
typically it would involve; power down of equipment, calling Fire Brigade
and input to first leg of automatic Fire Extinguishing systems. Follow
instructions given to you by your Fire Warden. Act strictly in accordance
with the Emergency Plan for your building or area.
As with the PRE-ALARM level, if no obvious smoke is present in the area, it
maybeusefultoverifyifthebargraphisstillilluminatedfortheareainwhich

mean that it was a transient burst of smoke which is no longer present. If
it remains illuminated, then it is likely that an incipient fire is present in the
area, or an unusual smoke producing process is taking place.
Extra audible or visual alarms will normally be sounding within the area

is necessary.
NOTE - Because the Stratos®system is capable of detecting extremely low
levels of smoke, The staged alarm facility may be configured so that
increasing levels of alarm can signal an increasing degree of danger.

SMOKE DENSITY
This ten segment bargraph shows the current smoke density sensed by the system. This
bargraph also displays other information during the TEST routine (see below) and it gives
a 'rolling' single segment display during the fifteen minute duration Fastlearn™ routine.
Thered AUX, PRE-ALARM & ALARM LED,s will operate whenthebargraphdisplay reaches
the pre-set levels at which the output relays operate.
The TEST routine establishes the settings programmed into the detector by operating
various LED's in sequence. These settings include; The position of the alarms in relation to
the Bargraph, the duration of the Delays and the present sensitivity of the detector being
tested.
PUSH BUTTONS
(only operational when enabled at programmable functions 35, 36 and 37)
RESET- This button resets any latched Alarm or Fault relays. It also takes the unit out of
programming mode.
TEST- This button performs a self test on the currently indicated detector as shown on the
'SLAVEDETECTORS'displayand shows;AlarmLevels,TimeDelaysandDetectorSensitivity.

Entries in this log are shown with time and date of occurrence. The event log can be printed to
a serial printer via Function 45 or shown on Screen via an IBM compatible PC and then printed
to the PC's printer. The Event Log is capable of storing approx. 100 entries, and when it is full it
over-writes the oldest event in the buffer.

it may be used as a post FIRE warning indicator. Actions in the event of an

transmittedtotheFireIndicatorPanel.ActionsintheeventofthePre-Alarm

Extra audible or visual alarms may now be sounding which are connected
to the Fire Indicator Panel. Urgent action is necessary.
You should contact your Supervisor or Floor Fire Warden immediately,
informing them of the problem.
NOTE-BecausetheStratos®systemiscapableofdetectingextremelylowlevels
of smoke, an alarm condition need not mean that the area needs to be
immediately evacuated. The staged alarm facility may be configured so that
increasing levels of alarm can signal an increasing degree of danger.
