GAS VAPOR DETECTOR
TESTING THE SYSTEM
The M-1 gas vapor detctior can be tested for electrical
continuity by pressing the "TEST" switch. The red LED
will come on. The light will glow as long as the switch is
held down. If the test switch is held down longer than 10
seconds, the horn will sound and the "MUTE" switch
must be pressed to silence the horn.
Unplug the sensor wire from the display head while the
unit is powered up. The red LED will illuminate and
within 10-15 seconds the alarm horn will sound. If
warning red LED fails to come on and horn fails to sound
remove display immediately and return direct to
manufacturer for repair or replacement.
FUNCTIONAL SENSOR TESTING
To test sensor use a butane lighter with the striker wheel
removed. Hold the lighter to the sensor and press down
on the lever to release the butane. In 3 to 4 seconds the
warning light will come on. In about 10 seconds the alarm
horn will sound. Remove lighter from the sensor. Mute
the alarm horn and within several seconds the warning
light will shut off.
Note: The M-1 alarm may be muted with the "MUTE"
button, but the problem should not be considered cleared
until the alarm light goes out.
The factory recommends replacing the sensor every 3
years due to the hostile marine environment.
The most likely problem that will be encountered is
continuous alarming. If this should occur, and you are
positive that there is no gas fumes present, check for recent
use of solvent, paint or paint thinner, polish, etc. If none
of these vapors are present, the next step is to throughly
check the sensor wires for loose connections, broken wies,
and water or oil contamination. Since the sensors are
normally part of a closed system, broken wires will cause
the alarm to sound.
