WARNING: LIMITATIONS OF FUME DETECTORS
Gasoline Fume detectors will not work without power
.
Examples causing no detector power are
an open circuit breaker, blown or missing fuse, broken wire or improper wire crimp connection.
CAUTION - This detector will only indicate the presence of gasoline fumes at the sensor.
The
sensor cannot monitor a compartment that is separated by a bulkhead. Gasoline fumes may be
present in other areas.
MTI recommends that sensors be installed in compartments where gasoline
fumes may accumulate.
Gasoline fume detectors may not be heard.
The alarm loudness is designed to meet or exceed
regulatory standards; however, the alarm may not be heard if detectors are installed in remote
locations. The alarm may not be heard by persons who are hard of hearing.

WARNING: WHY EVERY BOAT NEEDS A FUME DETECTOR
Gasoline vapors can develop in fuel pumps, fuel tanks, fuel lines, carburetors and fuel systems.
The SAFE-T-ALERT™ MGD-1 and MGD-1XL detectors are for Marine Use. They are an early
warning monitor, designed to notify the user when 20% or less of the lower explosive limit of
gasoline fumes are present in the monitored area.
