PROCEDURES TO TAKE DURING AN ALARM
!
WARNING--ACTIVATION OF THIS ALARM INDICATES THE PRESENCE OF DANGEROUS
LEVELS OF GASOLINE /PROPANE VAPORS OR HEAT THAT COULD CAUSE AN EXPLOSION OR
FIRE. IT ALSO INDICATES THE PRESENCE OF RISING WATER IN YOUR BOAT.
TAKE THESE STEPS IF AN ALARM SOUNDS:
If the Fume Alarm Sounds:
Turn off all electrical equipment, generators; extinguish all open flames (oven, cook top, smoking materials, etc.).
Turn off the engine(s) if safe navigation conditions exist. Open the engine compartment, ports, hatches and doors and
ventilate the area. If you are ashore, evacuate the boat. Do not return until the area is ventilated and the detector has
returned to normal standby condition. Proceed with caution and locate and repair the cause of the leak. Seek a
qualified technician if necessary. Do not start or use the boat until all the necessary repairs are made.
If the Heat Alarm Sounds:
Check the engine(s) temperature. If there is smoke coming from the engine room/compartment and there is no automatic
fire suppression system in the engine room/compartment; put on your life jackets, radio the Coast Guard and leave the boat
if necessary. Get as far away from the boat as possible. DO NOT OPEN THE ENGINE ROOM DOOR OR HATCH.
If the Water AlarmSounds:
Put on your life jackets. Check the bilge pump water outlet to determine that the pump is running. If it is not running,
manually start bilge pump. Open the hatch or compartment and try to determine the cause of the water leak. If more water
is entering the boat then the pump can handle, radio the Coast Guard for assistance.

WARNING
WHY EVERY BOAT NEEDS A COMBINATION DETECTOR
Every year, boating injuries and deaths can be attributed to explosions that could have been avoided. Fumes
from even a half cup of gasoline have the explosive force of six sticks of dynamite. With a boat’s gas-powered or
propane-powered engines, vapors can easily develop in pumps, tanks, lines, or carburetors and cause explosions
or fires.
The SAFE-T-ALERT™ SA-10XL combination detector system is exclusively designed, tested for use in the
harsh marine environment. The unit is an early warning detector that monitors for the buildup of explosive gases,
high heat and heat from fire, and bilge for high water.
!
WARNING
LIMITATIONS OF COMBINATION DETECTORS
Detectors will not work without power. Some reasons your detector may not have power include an open circuit
breaker, a blown or missing fuse, a broken wire or improper wire crimp connection.
This detector may not be heard. The detector’s loudness is designed to meet or exceed regulatory standards;
however, the alarm may not be heard if units are remotely located. Individuals who are hard-of-hearing, have
consumed alcoholic beverages, have taken prescription, non-prescription or illegal drugs may not hear the alarm. If
your boat has any sleeping areas, consider installing additional detectors in that area.
This detector will only indicate the presence of gasoline fumes or heat at the sensor. The sensor cannot monitor a
compartment that is separated by a bulkhead. Gasoline fumes and heat may be present in other areas. MTI
recommends that sensors be installed in ALL compartments containing fuel tanks and/or engine(s) and compartments
where gasoline or propane fumes or heat may accumulate.
INSTALLATION INSTRUCTIONS
Assemble the following supplies: An 3/8” (9.525 mm) electric drill, ¼” (6.35 mm) and 7/64” (2.77812 mm)
drill bits, 2-1/8” (53.975mm) hole saw, electric jigsaw, screwdrivers (Phillips and slotted), stainless-steel pan
head screws, washers bolts, nuts, locking nuts, silicone sealant, 18-gauge wire, 14-gauge wire, inline fuse holder,
1A fuse, wire stripper, crimping tool, crimp connectors, adhesive-lined heat shrink tubing, split loom wire wrap,
heat gun, wire supports, and cable ties.
When you have the supplies on hand, take the following steps:
Installing the Control Panel
1. Locate the control panel at the helm where it can be easily seen and heard. Check first to be sure that there is
at least 3 inches (76.2 mm) of clearance behind the location to allow for mounting and wiring. Drill a 2 1/8

inch (53.975 mm) hole and mount the control panel. Use a marine-grade silicone sealer if the unit is exposed to
the weather. DO NOT CONNECT POWER UNTIL THE INSTALLATION IS COMPLETE.
2. Connect the cable assembly to the control panel and run it to the engine compartment. Secure the run every 18
inches (457.2 mm) with plastic wire supports.
Installing the Fume Sensor
3. Locate the fume sensor in a dry area on a forward bulkhead in the engine compartment. The sensor should be at
the same height as the starter motor. Orient the sensor so that the 4-wire cable is facing down. This will prevent
any water or condensed water vapor from entering the unit. Connect the cable assembly from the control panel to
the sensor.
CAUTION: Gasoline and Propane are heavier than air. Mount the sensor at the engine starter height. Starter
height is dependent on the engine installation
4. Connect a 1A inline fuse holder to the red (+) lead of the control panel. Run a length of red (+) 18-gauge wire to
the positive terminal on the 12V main battery. Run a length of 18-gauge yellow or black (-) wire to the negative
terminal on the 12V battery. Use ring-type insulated crimped connectors at the battery end of the run. Secure the
run every 18 inches (457.2 mm) with plastic wire supports. As added protection, use adhesive-lined shrink
tubing on all crimped connections.
Installing the Water Sensor
5. Mount the water sensor about 4” (101.6 mm) above the automatic bilge pump switch. Connect one blue lead to a
water sensor wire and the yellow lead to the other water sensor wire. Do not mount the sensor where it will get
wet or submerged in water during normal operation. Do not mount with the cable up as water can run into
the sensor assembly and damage the sensor assembly. Connect the 20 foot (6096 mm) cable.
Installing the Fire/Heat Sensor
6. Connect the white lead to one of the white heat sensor wires. Connect the Blue lead to one of the Heat Sensor
Black wires. Install the sensor above the engine(s) and as high as possible in the compartment
7. When installation is complete, run a system check of all sensors and the control panel. Be sure to turn the unit
off when leaving the boat, as constant monitoring will run down the 12V battery.
The assembled system should look similar to the following:
ADDITIONAL INSTALLATION TIPS
DO NOT mount the control panel under a cowling, or glass or plastic panel where it may not be seen or heard.
DO NOT locate the fume sensor above batteries. Hydrogen from the batteries may cause false alarms.
DO NOT locate the fume sensor behind any obstruction that will prevent air flow to the sensor.
DO NOT locate the fume sensor on the aft bulkhead. Water on the sensor will cause permanent damage to the sensor
and sensor assembly.
DO NOT locate the fume sensor within 12 inches (304.8 mm) of exhaust lines. High heat may cause false alarms.
OPERATION
The SA-10XL has supervisory circuits to warn of a missing sensor, sensor assembly malfunction, disconnected or a broken
connector sensor cable.
1. Press the control panel’s ON pad. The WAIT (YELLOW) light should light. Press the TEST pad to check the operation
of the alarm sounder and alarm light. In about two minutes the WAIT (YELLOW) light will turn off and the ON
(GREEN) light will light. The unit is now operational and is monitoring for all conditions.
2. When the sensor detects fumes, heat, or bilge water above the alarm threshold levels, the alarm will sound and the RED
alarm light will activate. The alarm will continue until the air in the monitored area returns to safe levels. See
PROCEDURES TO TAKE DURING AN ALARM.
TESTING
!
WARNING
TEST THIS DETECTOR’S OPERATION AFTER THE BOAT HAS BEEN IN STORAGE, BEFORE EACH
TRIP AND AT LEAST ONCE PER WEEK DURING USE.
!
WARNING
