Identification

• It is important to identify what type of detector
  is installed when asking for assistance or
  ordering spare parts.

4
Identification of Models
Stratos-HSSD-A Package A type detector -
identified by a model number with the pre-fix
MA. Stratos-ES Enhanced Sensitivity
Identified by a model number with the suffix
ES Stratos-HSSD-B Package B type
detector, identified by the model number 30600
or 30601, located inside the front
door. Stratos-Quadra Identified by the model
numbers 30120, 30121, 30122 or 30110, located
inside the front door.
5
Identification of Models
Stratos-HSSD-2 Identified by the model numbers
30620, 30621 and 30710 located on detector
chamber beside filter change label (remove
front cover). Stratos-Micra 25 Identified by
the model number 30750 located on inside rear
wall of detector (remove front
cover). Stratos-Micra 100 Identified by the
model number 30740 located on inside rear wall
of detector (remove front cover).
6
Maintenance
To be carried out at quarterly intervals.
7

• 1. Isolate the detector at the main fire panel.
•  
• Inspect the case for signs of physical damage,
  moisture ingress and ensure the detector is
  securely mounted to wall.
• Note the flow readings as a benchmark for future
  service visits.
• Rectify any faults as indicated on the front
  panel.
• Check the correct operation of the front panel
  buttons (enable where necessary).

8

• Remove all power from the detector.
• Ensure the smooth operation of lock mechanism.
• Ensure all field wiring is secure and that all
  insulation material is undamaged.
• Ensure the exhaust port is not blocked or
  obstructed.

9
10. After first taking the relevant safety
precautions i.e. safety glasses, respiratory mask
and gloves. Use an air duster to remove any
debris from inside detector. NB Health Safety
Notice. Unless suitable precautions are taken
maintenance personnel may be exposed to a
Nuisance Dust hazard as defined by the Control
of Substances Hazardous to Health (COSHH)
Regulations. 11. Restore all power to the
detector, mains first, followed by the battery.
10
12. Carry out a functional smoke test on 25 of
the system subsequent functional testing must
result in 100 system test per annum. Allow smoke
to disperse and, if provided, the bar graph level
on the relevant detector to return to normal
before proceeding further. 13. De-isolate the
detector at the main fire panel and place the
relevant detection loop of main fire panel in to
test or commissioning mode to allow relay
testing. 14. Verify the correct operation of all
relays through to main fire panel.
11
15. Ensure that no existing faults or alarms are
indicated on the detector front panel before
restoring the main fire panel to normal
operation.
12
Maintenance
To be carried out at six monthly intervals in
addition to the quarterlymaintenance procedures.
13

• Isolate detector at main fire panel to avoid a
  fault condition being reported.
• 2. Check the physical condition of the
  batteries test the batteries to ensure that they
  hold sufficient charge to provide the required
  standby time Replace where necessary.
• 3. Check the integrity of the sampling pipe
  network.
• 4. Ensure no existing faults or alarms are
  indicated on the detector front panel before
  restoring the main fire panel to normal
  operation.

14
Maintenance
To be carried out at yearly intervals in addition
to the six month and quarterly maintenance
procedures.
15

• Isolate detector at main fire panel to avoid a
  fault condition being reported.
• 2. Remove all power from the detector.
• 3. After first taking the relevant safety
  precautions i.e. safety glasses, respiratory mask
  and gloves, remove the aspirator, clean the
  plenum area and aspirator using an air duster.
• NB Health Safety Notice. Unless suitable
  precautions are taken, maintenance personnel may
  be exposed to a Nuisance Dust hazard as defined
  by the Control of Substances Hazardous to Health
  (COSHH) Regulations

16
4. Inspect the sampling pipe network, checking
that the sampling points are clean and clear of
obstructions. Should dust accumulation be present
in the sampling system, it is recommended that
this contamination is removed. 5. Refit the
aspirator and all other parts removed for
cleaning. 6. Restore all power to the detector,
mains first, followed by the battery.  
17
7. Ensure no existing faults or alarms are
indicated on the detector front panel before
restoring the main fire panel to normal
operation.  
18
Maintenance
Systems fitted with a Heater Box
19
1. Remove all power from the detector. 2.
Remove all power from the Heater Box and isolate
the electrical supply. 3. Allow the Heater
Box to cool before undertaking any service
activity.
20
4. After first taking the relevant safety
precautions i.e. safety glasses, respiratory mask
and gloves, remove the cover from the Heater Box.
NB Health Safety Notice. Unless suitable
precautions are taken, maintenance personnel may
be exposed to a Nuisance Dust hazard as defined
by the Control of Substances Hazardous to Health
(COSHH) Regulations.
21
5. Significant accumulations of dust should be
removed with a vacuum cleaner or similar
collection method. 6. Check the interior of
the Heater Box and the security and integrity of
the wiring.
22
It is highly recommended that two suitable cable
ties e.g. RS 442-3205 are fitted as shown below,
in order to guard against wires working loose.

29
Frequency ?

• Does the fault occur on a regular basis ?

30
Frequency ?

• Does the fault occur on a regular basis ?
• If so, does the time in the event log correspond
  to any activity within the area ?

31
Frequency ?

• Does the fault occur on a regular basis ?
• If so, does the time in the event log correspond
  to any activity within the area ?
• Daily, weekly or monthly a pattern may help trace
  the cause of the fault.

Logical Process
41
Logical Process

• Establish the type of fault

42
Establish the type of fault
A text message on the front panel LCD display of
the standard Stratos-HSSD 2 detector will
indicate the nature of any fault.
43
Establish the type of fault
For those detectors not fitted with a dedicated
display the fault could be displayed at the
Command Module.
44
Establish the type of fault
Where a Command Module is not used a laptop
computer, serial connection lead and appropriate
software will be required to determine the fault.
45
Logical Process

• Establish the type of fault
• The frequency of any reoccurring fault
