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 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 Det-Tronics

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.

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 window and reflective surfaces

of the oi plate using a clean cloth, cotton swab or

tissue, and Det-Tronics window cleaning solution.

Use Isopropyl alcohol for contaminations that

the Det-Tronics window cleaning solution can not

remove. If a fault condition is still indicated after

cleaning, remove and clean the oi 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 14.

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

reflector plate without also

recalibrating the

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.

pERIODIC CHECKOUT pROCEDURE
A checkout of the system using the Mag oi or Man oi

feature should be performed on a regularly scheduled

basis to ensure that the system is operating properly. To

test the system, perform the “Manual oi Test,” “Count Test

Mode” or “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.
