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 X9800 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 o i plate, use Det-Tronics
window cleaner (part number 001680-001) and a soft
cloth, cotton swab or tissue and refer to the procedure
below.
1. Disable any extinguishing equipment that is
connected to the unit.
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. To clean the optical surfaces, remove the o i plate
following the procedure described below.
3. Thoroughly clean both viewing windows and
reflective surfaces of the o i plate 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.
4. Re-install the o i plate following the procedure
described below.

2. Loosen the two captive screws, then grasp the o i
plate by the visor and remove it from the detector.
See Figure 14.
3. Thoroughly clean the o i plate reflective surfaces,
holding it by its edges to avoid leaving fingerprints
on the inside reflective surface.
4. Re-install the o i plate. Ensure that the plate is
flat on the detector surface. Tighten the o i plate
screws securely (40 oz/inches).
If the o i plate is removed, be sure to install
the original o i plate.
interchangeable and should not be mixed with
o i plates from other detectors. If corrosive
contaminants in the atmosphere cause the o i
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
o i plate replacement procedure.
pERIODIC CHECKOUT pROCEDURE
A checkout of the system using the manual or magnetic
o i feature should be performed on a regularly scheduled
basis to ensure that the system is operating properly. To
test the system, perform the "Manual o i 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.
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.
