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 window 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 Det-

Tronics 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
