9. MAINTENANCE: CLEANING YOUR DETECTOR
You can clean your detector by using a vacuum cleaner hose and vacuuming around
the openings on the detector. The outside of the detector can be wiped with a damp
cloth. NO chemical detergent should be used to clean this detector. After cleaning,
test your detector by using the TEST/RESET button and check that the green
LED is on.
10. LIMITATIONS OF NATURAL (METHANE) GAS DETECTORS
Natural (Methane) gas detectors are devices that can provide an early warning of the
presence of natural (methane) gas at a reasonable cost. However, detectors have
sensing limitations and may not always sound a warning of the presence of natural
(methane) gas. STCH-1000 series A.C. powered detectors will not operate if the A.C.
power has been cut off, such as by an electrical fire, a tripped circuit breaker or an
open fuse. These detectors must be tested regularly to make sure that they are
receiving power and operating properly. Detectors cannot sense natural (methane)
gas that does not reach the detector and therefore, detectors may not detect natural
(methane) gas, which is in a different area of a home. If the detector is located on a
different level of the home or on the other side of a closed door, it may not waken a
sound sleeper. The use of drugs and alcohol may impair one's ability to hear the
alarm. If you have a multi-level home, install detectors on each level of the home. If
the detector is installed in a hallway and the bedroom doors are kept closed at night,
install a detector in each bedroom.
