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.
NOTE
Refer to the X5200 Safety manual (95-8672) for
specific requirements and recommendations
applicable to the proper installation, operation,
and maintenance of all SIL-Certified X5200 Fame
Detectors.
To maintain maximum sensitivity and false alarm
resistance, the viewing windows of the X5200 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) with a soft cloth, cotton swab,
or tissue and refer to the following procedure:
1. Disable any extinguishing equipment that is
connected to the unit.
NOTE
Remove input power when cleaning the detector
windows. The rubbing motion on the surface of
the windows during cleaning can create static
electricity that could result in unwanted output
activation.
2. Clean the viewing windows and reflective surfaces
of the oi plate using a clean cloth, cotton swab,
or tissue with the window cleaning solution. Use
Isopropyl alcohol for contaminations that the
window cleaning solution can not remove. If a fault
condition is still indicated after cleaning, remove and
clean the oi plate using the oi Plate Removal and
Replacement procedure.
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 18.
3. Install the new (or cleaned) oi plate.
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.
