Cleaning Windowed Enclosures and Detectors
The optical window (lens) of the Model SS4-AS/-AS2 Detector should be cleaned
periodically on a regular maintenance schedule. For clean area applications,
perhaps monthly cleaning schedule will be sufficient. For extremely contaminated
application environments, such as truck filling stations with presence of black
carboneous smoke, daily cleaning schedule may be necessary.
Clean the window of the Detectors each time they are handled, the windows
appear contaminated, fails Built-In-Test, or the Detector fails an end-to-end test
with a handheld UV/IR Test Lamp FT2045. If necessary, clean the Detector
Module Sensors each time the Detector has been disassembled for wiring or
replacement.
Use a blast of an air hose or an oil-free cloth to clean the enclosure window. Oil
degrades the performance of UV Detectors. Occasionally, the use of a solvent,
such as alcohol is acceptable. No disassembly of the Detector is required.
DO NOT USE SILICONE-BASED OR COMMERCIAL WINDOW
CLEANING PRODUCTS. THESE WILL DEGRADE THE MODEL
SS4-AS/-AS2 DETECTOR PERFORMANCE.
3.3
Personnel Training
Troubleshooting of the Model SS4-AS/-AS2 Detector should be performed only
by qualified authorized personnel observing all standard safety practices.
Although the Detector operates on safe 24 Volts DC, the FM Approved or UL
listed Fire Alarm Panel's power supply may operate on life threatening 120 or
240 Volts AC.
WARNING: Hazardous voltages may be present during testing
procedures. Serious injury or death may result due to failure to
observe safety precautions.
CAUTION: Model SS4 Detector modules and their components
are susceptible to permanent damage due to electrostatic discharge
(ESD).
DO NOT handle a module without adequate grounding precautions.
WARNING: Potential electrostatic hazard. Do not rub with dry cloth.
