A LARM MUTE
This feature is activated by pressing the TEST/MUTE button when the detector is in alarm. 1. The Red LED will continue flash and the alarm will beep every 30 seconds, until the gas level has dropped to a safe level then, 2. The LED will flash Green until the end of the Mute cycle and/or, 3. Return to Red and beep 4 times if high gas levels return before the end of the mute cycle, then, 4. Return to normal (solid Green) or resound the alarm in approximately 2 minutes if dangerous levels of gas remain in the area.
MALFUNCTION ALARM
The microprocessor will activate the malfunction alarm when it detects a fault in the detectors operation. The LED will alternately flash Red and Green, while the sounder beeps once every 15 seconds. The Reset switch will not function. REMOVE THE DETECTOR IMMEDIATELY AND RETURN IT FOR REPAIR OR REPLACEMENT.

SPECIAL FEATURES OF THE SAFE-T-ALERT TM GAS DETECTORS
Your Safe-T-Alert gas detector uses the latest microprocessor technology. This detector has been tested and listed as a Propane and Methane (Natural Gas) detector. Other explosive gases detected but not tested by Underwriters Laboratories include Acetone, Alcohol, Butane, Gasoline all of which you may have in your home.
To prevent false alarms from brief “puffs” of explosive gases the detector has a short recheck cycle before alarming. If high levels of explosive gases remain after recheck the detector will alarm.

Clean the detector cover when dirty. Hand wash using a cloth dampened in clean water. Dry with a soft cloth.
DO NOT SPRAY CLEANING AGENTS OR WAXES directly onto the front panel. This action may damage the sensor and cause the detector to malfunction.
1.   Determine the proper installation location (SEE WHERE TO AND WHERE NOT TO INSTALL GAS DETECTOR SECTION)
2.   Remove the cover plate screw, plug the transformer into the outlet and fasten it to the wall plate using the wall plate screw.
3.   Fasten the detector to the wall using the two screw holes located on the front of the case. Reconnect the power supply. Coil any loose wire to prevent tripping.
OPERATION
POWER ON Warm Up: When power is first applied the Yellow LED will flash for 3 minutes while the detector is warming up. At the end of that time the LED will turn Green indicating full operation. If the detector has detected unsafe levels of gas it will immediately go into alarm. Caution- This detector cannot alarm during the 3 minute warm up cycle.
TESTING
WARNING: TEST THE OPERATION OF THIS DETECTOR AT LEAST ONCE PER WEEK
Simply press the detectors Test switch any time during the warm up cycle or while in normal operation. The LED should flash RED and the alarm should sound. Release the switch. THIS IS THE ONLY WAY YOU SHOULD TEST YOUR DETECTOR. THIS TEST FEATURE CHECKS THE FULL OPERATION OF THE DETECTOR. If this detector doe s not test properly return the detector immediately for repair or replacement.
ALARM
The Red LED will Flash and the alarm will sound whenever dangerous levels of gas are detected. The detector will continue to alarm until the gas clears or the Reset switch is pressed. (See Procedures Take During An Alarm)
PROCEDURES TO TAKE DURING AN ALARM
1 . TURN OFF ALL GAS APPLIANCES, (STOVE, HEATERS,
FURNACE), EXTINGUISH ALL FLAMES AND SMOKING MATERIAL. EVACUATE, LEAVE DOORS AND WINDOWS OPEN.
2.   TURN OFF THE PROPANE \CNG TANK VALVE
3.  DETERMINE AND REPAIR THE SOURCE OF THE LEAK SEEK PROFESSIONAL HELP IF NECESSARY.
CAUTION- DO NOT RE-ENTER UNTIL THE PROBLEM IS CORRECTED.
/ ! \ WARNING
LIMITATIONS OF
PROPANE/METHANE GAS DETECTORS
THIS DETECTOR will not work without power .
Examples causing no power are: an open circuit breaker, a faulty power line connection, an open main breaker.
This detector will only indicate the presence of propane or methane gas at the sensor. Explosive gas may be present in other areas.
This detector 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 located in remote locations or behind closed doors. The alarm may not be heard by persons who are hard of hearing.
This detector is not smoke or fire detector, it is not
suitable as a smoke or fire detector.

» Observe the color of the indicator light on the front panel of the detector at frequent occasions and during your weekly test. (See - OPERATING INSTRUCTIONS).
WHERE TO INSTALL THIS GAS DETECTOR This gas detector is approved for installation in homes. This detector is detector should be located near sources of a potential gas leak. Some examples are a furnace, water heater, stove/oven. If potential sources of gas leaks are in two or more separated areas, MTI recommends installing a detector in each area.
CAUTION: Propane is heavier than air if the detector is being used for propane gas the detector should be installed within 4 to 20 inches from the floor.
CAUTION: Methane is lighter than air and the detector should be installed within 6 inches from the ceiling or on the ceiling at least 12 inches from a wall.
