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

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

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

plate using the

Plate Removal and

Replacement procedure.

Important

When used in extreme environments, the reflective
surface of the detector

plate may eventually

deteriorate, resulting in reoccurring

faults and

the need for

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

plate by the visor and remove it from the detector.

See Figure 18.

3. Install the new (or cleaned)

plate.

4. Recalibrate the detector's

system. Refer to the

Inspector Monitor manual (95-8581) for instructions

regarding

plate replacement and

system

recalibration.

CaUtIon

Do not replace the

reflector plate without also

recalibrating the

system.

Recalibration of the

Inspector Connector Cable and Inspector Monitor

Software. These two items are included in the

replacement kit, or they can be purchased separately.
