DUAL SENSOR TECHNOLOGY

The SAFE-T-ALERTTM 85 Series combination CO / Gas Alarm is an alarm that combines into a single compact system, a powerful alarm that detects both Carbon Monoxide (CO) and explosive Propane (LPG) gas. The 85 Series uses the latest microprocessor technology combined with two electronic selfcleaning sensors that operate independently of each other. The combined unit can detect both CO and explosive gases simultaneously.
This detector is listed as a CO and Propane gas detector for RV use. Other explosive gases detected, but not tested for, include Acetone, Alcohol, Butane, and Gasoline all of which you may have in your RV.

To prevent false alarms from brief “puffs” of gas the detector has a recheck cycle before alarming. If high levels of gas remain during the recheck cycle, the detector will alarm. The electronic CO sensor in your SAFE-T-ALERTTM CO alarm is very sensitive to CO gas. It will not react to safe levels of most other gases.

WHY EVERY RV NEEDS AN 85 SERIES CO AND GAS ALARM

Everyone is at risk for carbon monoxide poisoning! Particularly sensitive are children, pregnant women, the elderly and people with lung or heart disease or anemia! Carbon monoxide (CO) is an odorless, colorless gas that prevents the blood from carrying oxygen to vital organs. CO is 200 times more likely to replace oxygen in the blood. The Consumer Product Safety Commission (CPSC) recommends using at least one CO alarm located outside of sleeping areas. For the best security, locate a CO alarm in each sleeping area. Safe-T-Alert CO alarms are available for secondary installations.
Propane gas can cause explosions! Using propane requires taking safety precautions to avoid injury. LP gas is usually identified by an unpleasant odor. Certain conditions may make some people unable to detect this unpleasant odor. These conditions include advanced age, colds, allergies, and the use of tobacco, alcohol or drugs that may diminish the sense of smell.

ABOUT THIS ALARM

Because CO is a colorless, odorless, tasteless and highly poisonous gas; it can endanger lives even at low levels of concentration. The CO Alarm will alert you to potentially dangerous situations. The following symptoms may be related to CO POISONING. Discuss these symptoms with ALL household members and RV guests:

  • Mild Exposure: Headaches, running nose, sore or watery eyes, often described as “flu-like” symptoms.
  • Medium Exposure: Dizziness, drowsiness, vomiting.
  • Extreme Exposure: Unconsciousness, brain damage and death.

NOTE: Reported cases of CO gas poisoning indicate that while victims are aware they are not well, they are disoriented. They are unable to save themselves by exiting the RV or calling for assistance. Small children and pets may be affected first.
Your SAFE-T-ALERTTM 85 Series alarm helps protect your household members and guests from CO produced while using your RV. CO gas is produced when any type of fuel is incompletely burned. Potential sources of CO in and around your RV can include gas or diesel engine exhaust, portable space heaters, gas stoves and ovens, furnaces, defective engine exhaust systems, portable grills, other nearby RVs, portable generators, generator exhaust, and other propane-powered appliances. All are sources of CO.

The following are also sources of CO that may affect your RV:

  • Extended operation of unvented fuel burning appliances can build up high CO levels.
  • An idling vehicle in an open or closed garage.
  • Temperature inversions can trap exhaust near the ground.
  • CO build up can be caused by reverse/negative venting of fuel burning appliances including;
  1. Clogged, loose or faulty stacks or chimneys of (clothes dryers, furnaces and water heaters, etc.),
  2. wind direction and/or velocity,
  3. simultaneous operation of multiple fuel burning appliances, and/or exhaust fans.

WARNING:
LIMITATIONS OF CO and GAS ALARMS
THIS ALARM WILL NOT WORK WITHOUT POWER. Some reasons for no alarm power are; a blown or missing fuse, broken wire, a faulty wire connection or circuit breaker, a discharged battery, cut lead wires, or improper supply (+) or ground (-) connections.

THIS ALARM WILL ONLY INDICATE THE PRESENCE OF GAS AT THE SENSOR. CO or explosive propane/ gas gases may be present in other areas. MTI recommends installing CO alarms in all sleeping areas. Do not block or cover the alarm with any object that can prevent a gas leak or carbon monoxide from reaching the sensor.
THIS ALARM IS INTENDED FOR USE IN RV’s. It is intended for use in inside locations of a RV. It is not designed to measure compliance with commercial and industrial standards.
THIS ALARM MAY NOT BE HEARD. The alarm’s loudness is designed to meet or exceed regulatory standards; however, the alarm may not be heard if alarms are located in remote locations or behind closed doors. Persons who are hard-of- hearing, have consumed alcoholic beverages, taken prescription, non prescription or illegal drugs, may not hear the alarm.

THIS ALARM IS DESIGNED TO DETECT CARBON MONOXIDE AND PROPANE GAS. THE ALARM IS NOT DESIGNED TO DETECT SMOKE OR FIRE.

THIS ALARM MAY NOT ALARM AT LOW CO LEVELS – It is not designed to measure compliance with the Occupational Safety Health Administration (OSHA) commercial or industrial standards. Individuals with medical problems may consider using warning devices, which provide audible and visual signals for CO concentrations under 30 ppm.

THIS ALARM IS NOT A REPLACEMENT FOR INSURANCE.
Always be sure your RV is fully insured.

Warning: Installation of the device should not be used as a substitute for proper installation, use, and maintenance of fuelburning appliances, including appropriate ventilation and exhaust systems.

HOW TO PROTECT YOUR FAMILY

CAUTION- The SAFE-T-ALERTTM 85 SERIES combination CO and Gas Alarm is designed to protect individuals from the acute effects of carbon monoxide exposure and gas leaks. It will not fully safeguard individuals with specific medical conditions. If in doubt, consult a medical practitioner.
To protect your family, you should:

  • INSTALL THE ALARM PROPERLY. Carefully read and follow ALL the instructions in this manual. Test your unit every week. Alarms that do not work will not alert you to hazardous levels of CO or explosive gas. See the section, Test Procedure, in this manual for further information.
  • MAKE REGULAR VISUAL INSPECTIONS. Check all fuel burning equipment including gas water-heaters, kitchen gas stoves, space heaters, gas dryers and all pilot lights. Check the color of the pilot flame. The color should be blue.
  • MAKE REGULAR VISUAL INSPECTIONS OF THE ENGINE AND GENERATOR EXHAUST SYSTEMS. Cracked exhaust systems can allow CO to enter the living area.
  • PROFESSIONALLY MAINTAIN YOUR ENGINE AND GENERATOR. Although gas engines and generators produce CO, a poorly tuned engine and generator will produce greater amounts CO.
  • If you smell unusual odors you may have a gas leak, immediately call a local propane gas supplier or fire department to check for possible leaks.

WHERE TO INSTALL

  • Install the 85 Series in an area near sources of a potential gas leaks.
    Some potential sources are a furnace, refrigerator, stove or oven. If potential sources of a gas leak are in separate areas, MTI recommends installing a gas alarm in each area.

  • The Consumer Product Safety Commission recommends installing a CO alarm outside the sleeping area. The 85 Series combination CO and gas alarm complies with that recommendation.

  • INSTALL ALARM at least 4 inches but not more than 20 inches off the floor.

WHERE NOT TO INSTALL 85 SERIES ALARMS

  • DO NOT INSTALL behind furniture, drapes, in closets or areas that will block gas flow to the alarm
  • DO NOT INSTALL within 12 inches (30cm) of opening windows, exterior doors, heating or return vents, or other drafty areas.
  • DO NOT INSTALL on an outside wall.
  • DO NOT INSTALL on a wall switch controlled by a power line, ground fault circuit or to a circuit breaker.
  • NOTE: Older RVs may have little or no insulation and therefore are draftier. Carefully consider mounting locations.

TEST PROCEDURE

WARNING
TO REDUCE THE RISK OF CARBON MONOXIDE POISONING OR PROPANE GAS EXPLOSION, TEST THIS ALARM’S OPERATION AFTER THE RV HAS BEEN IN STORAGE, BEFORE EACH TRIP AND AT LEAST ONCE PER WEEK DURING USE.
WARNING
WARNING: THE TEST BUTTON ONLY TESTS THE ALARM CIRCUIT NOT THE SENSORS. YOU MAY USE PROPANE OR BUTANE GAS TO TEST THE GAS SENSOR. Note it may take up to 10 seconds for the alarm to sound.
TO TEST THE CO SENSOR USE A CAN OF SAFE-T-ALERT CO TEST GAS TO TEST THE 400 PPM CALABRATION POINT. DO NOT TRY TO GENERATE CO TO TEST THE ALARM. The TEST/RESET button tests all ELECTRICAL functions of the alarm. It does not check the sensor operation.

The alarm may be tested at any time -The TEST/Mute switch is located on the front of the alarm Press and hold the test button for 1 second. The alarm is working properly if the GREEN indicator light changes color to RED and the horn beeps 4 times. The Gas LED should also blink Red.

IMPORTANT – If this alarm does not test properly return it immediately for repair or replacement

OPERATION

Each time the unit is first powered up, the CO sensor requires a ten (10) minute initial warm-up period to clean the sensor element and achieve stabilization. The GREEN LED indicator will flash on and off during the 10 minute warm-up period. This unit cannot go into a CO alarm during the warm-up period. To test your unit during the warm-up period, press the test button. See Test Procedure in this manual. After the warm-up period, the GREEN power ON indicator should glow continuously If the ON indicator light does not light, see the section, Trouble-Shooting Guide, in this manual for further information. Do not attempt to fix it yourself.
Gas Alarm: When you power the alarm, it has a warm-up period of approximately 1 minute. This unit cannot go into a gas alarm during the warm- up period. After 1 minute the alarm can detect explosive gas.
Simultaneous CO and Gas Alarms — Because the risk of a propane gas explosion is generally a more serious danger, your alarm unit gives the gas alarm a higher priority during simultaneous alarm condition.
If your unit generates alarms for both Gas and CO at the same time, the gas LED will flash red and the beeper will sound. The CO LED will be a solid Red until the CO is ventilated out of the RV, at which time the LED will return to the Green operational/safe color.
Brownout Protection – The unit can tolerate short power interruptions and brownouts where the circuit voltage drops as low as 1VDC. If the brownout lasts too long, the unit will reset and operate as described above.

LOW POWER OPERATION

This alarm will operate normally down to7 VDC. Do not operate this alarm below 7 VDC.
