Important
Periodic flamepath inspections are not
recommended, since the product is not intended
to be serviced and provides proper ingress
protection to eliminate potential deterioration of the
flamepaths.
WarnIng
The sensor module (“front” half of the detector)
contains no user serviceable components
and should never be opened. The terminal
compartment is the only part of the enclosure that
should be opened by the user in the field.
To maintain maximum sensitivity and false alarm
resistance, the viewing windows of the X3302 must be
kept relatively clean. Refer to the procedure below for
cleaning instructions.
CLEANING pROCEDURE
CaUtIon
Disable any extinguishing equipment that is
connected to the unit to prevent unwanted
actuation.
To clean the windows and
oi
plate, use Det-Tronics
window cleaner (part number 001680-001) and a soft
cloth, cotton swab or tissue and refer to the following
procedure.
1.
Disable any extinguishing equipment that is
connected to the unit.
2. Since the X3302 is less affected by contamination
than other detectors, removal of the
oi
plate is
needed only under extreme conditions. In addition,
it is not necessary to achieve perfect cleanliness,
because IR is not significantly absorbed by slight
films of oil and/or salt. If a fault condition is still
indicated after cleaning, remove and clean the
oi
plate using the following procedure.
3. Clean all three viewing windows and reflector
surfaces thoroughly using a clean cloth, cotton swab
or tissue and Det-Tronics window cleaning solution.
If a stronger solution is needed, isopropyl alcohol
may be used.
Oi
pLATE REMOVAL
Loosen the two captive screws, then grasp the
1.
oi
plate by the visor and remove it from the detector.
See Figure 17.
Thoroughly clean the
2.
oi
plate reflective surfaces,
holding it by its edges to avoid leaving fingerprints
on the inside reflective surface.
Re-install the
3.
oi
plate. Ensure that the plate is flat
on the detector surface. Tighten the
oi
plate screws
securely (40 oz/inches).
NOTE
If the
oi
plate is removed, be sure to install
the original
oi
plate.
Oi
plates are not
interchangeable and should not be mixed with
oi
plates from other detectors. If corrosive
contaminants in the atmosphere cause the
oi
plate surface to deteriorate to the extent that it is no
longer possible to restore it to its original condition,
it must be replaced. Consult factory for
oi
plate
replacement procedure.
pERIODIC ChECkOUT pROCEDURE
A checkout of the system using the manual or magnetic
oi
feature should be performed on a regularly scheduled
basis to ensure that the system is operating properly. To
test the system, perform the “Fire Alarm Test” as described
in the “Startup Procedure” section of this manual.
CLOCk BATTERY
The real time clock has a backup battery that will operate
the clock with no external power for nominally 10 years.
It is recommended that the battery be replaced every
7 years. Return the device to the factory for battery
replacement.
NOTE
If the backup battery is depleted, there is no effect
on the operation of the flame detector, but the time
stamping of the data log may be affected.
