MAINTENANCE
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 following procedure 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 the window
cleaner (p/n 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
oi
Plate Removal and Replacement
procedure.
3. In all environments, clean all three viewing windows
and reflector surfaces thoroughly. Use a cotton
swab and the Det-Tronics window cleaning solution.
Use Isopropyl alcohol for contaminations that the
Det-Tronics window cleaning solution can not
remove.
Important
When used in extreme environments, the reflective
surface of the detector
oi
plate may eventually
deteriorate, resulting in reoccurring
oi
faults and
the need for
oi
plate replacement.

pLaTE REMOvaL aND REpLaCEMENT
1. Disable any extinguishing equipment that is
connected to the unit.
2. Loosen the two captive screws, then grasp the
oi
plate by the visor and remove it from the detector.
See Figure 14.
3. Install the new (or cleaned)
oi
plate.
NOTE
When installing the stainless steel plate, ensure
that the gasket is present and correctly seated to
prevent moisture or contaminants from penetrating
behind the plate. To ensure even seating, tighten
both screws equally.
4. Recalibrate the detector’s
oi
system. Refer to the
Inspector Monitor Manual (95-8581) for instructions
regarding
oi
plate replacement and
oi
system
recalibration.
CaUtIon
Do not replace the
oi
reflector plate without also
recalibrating the
oi
system.
Recalibration of the
oi
system requires the use of the
Inspector Connector Cable and Inspector Monitor
Software. These two items are included in the
oi
replacement kit, or they can be purchased separately.
See Ordering Information for details.
X3302 Reflector plates
X3302 models are supplied with either a black or a
stainless steel reflector plate. These plates are not
interchangeable. Order the replacement that matches
the reflector plate on your X3302 detector.
