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 X2200 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 oi 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.
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. To clean the optical surfaces, remove the oi plate
following the procedure described below.
3. Thoroughly 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. If a stronger solution is needed, isopropyl
alcohol may be used.
4. Re-install the oi plate following the procedure
described below.

pLATE REMOvAL
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. Thoroughly clean the oi plate reflective surfaces,
holding it by its edges to avoid leaving fingerprints
on the inside reflective surface.
4. Re-install the oi plate. Ensure that the plate is flat
on the detector surface. Tighten the oi plate screws
securely (40 oz/inches).
NOTE
If the oi plate is removed, be sure to install
the original oi plate. oi plates are not
interchangeable and should not be mixed with
oi plates from other detectors. If corrosive
contaminants in the atmosphere cause the oi
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
oi plate replacement procedure.
pERIODIC ChECKOUT pROCEDURE
A checkout of the system using the manual or magnetic
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.
NOTE
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.
