DESCRIPTION AND APPLICATIONSThe MCT-425 is photoelectric smoke detector designed to sensesmoke, but not gas, heat or flame and fitted with a Power-Code-type UHF transmitter. It provides early warning of developingfire by sounding an alarm with its built-in alarm horn, and bytransmitting a coded alarm signal to a PowerCode receiver or to acompatible wireless alarm control panel.It must be borne in mind, though, that effective pre-warning of fireaccidents is only possible if the detector is located, installed andmaintained properly as described in this manual. WARNING: This smoke detector is designed for use in a singleresidential unit only, which means that it should be used inside asingle family home or apartment. It is not meant to be used inlobbies, hallways, basements or another apartment in multi-familybuildings, unless there are already working detectors in eachfamily unit. Smoke detectors, placed in common areas outsidethe individual living unit, such as on porches or in hallways, maynot provide early warning to residents. In multi-family buildings,each family living unit should obtain its own detector.WARNING: This detector is not meantto be used in non-residential buildings.Warehouses, industrial or commercialbuildings and special purpose non-residential buildings require special firedetection and alarm systems. Thisdetector alone is not a suitablesubstitute for complete fire detectionsystems for places where manypeople live or work, such as hotels ormotels. The same is true ofdormitories, hospitals, nursing homesor group homes of any kind, even ifthey were Figure 1. General Viewonce single family homes. Please refer to NFPA 101, the LifeSafety Code, NFPA71, 72A, 72B, 72C, 72D and 72E for smokedetector requirements for fire protection in buildings not defined as"households".WARNING: This detector, if used as a stand-alone unit, will notalert people who are hard of hearing.2222. INSTALLATION SUMMARY. INSTALLATION SUMMARY. INSTALLATION SUMMARY. INSTALLATION SUMMARY2.1 DisassemblySeparate the unit from its mounting bracket as shown in Figure 2.Figure 2. Separating the MCT-425 from its Bracket2.2 Setting the Function SwitchThe MCT-425 has a 4-position DIP switch function selector (seeFigure 3).

Function Selector and Battery Cover2.3 Definitions of LED Light and BuzzerThe red and yellow LED light and buzzer turn on and/or off toindicate various situations. There are several LED light andbuzzer operations.A. When the red LED flashes every 30 seconds, this meanspower on, i.e., the detector is energized.B. When the red LED flashes and the buzzer beeps intermittently,this means alarm for potential smoke hazard.C. When the red LED flashes together with buzzer beeps for every30 seconds with temporal tone 0.5 second on and 0.5 secondoff intermittently, this means battery power is low.D. The yellow LED turns on every time an RF signal is transmittedto the control panel.2.4 Battery Connection and Initial TestCAUTION: The MCT-425 is fitted with cover latches that willprevent the cover from closing if there is no battery inside. The smoke detector is supplied with a 9V battery seated within itsholder but insulated from the battery terminals.BRACKET DETECTOR❷Rotate UnitCounter-Clockwise❶Seize Bracket❸Pull AwayFromBracketTestButtonTAMPER

Theclip will not fit if the contacts are reversed, but take carenot to make a prolonged reverse contact - the battery willdischarge rapidly through the built in protection diode! Note: When the battery first makes contact, the alarm horn maysound for one second. This indicates that the battery isconnected properly.B. Push the battery firmly in until it is seated tightly within theholder, with the snap-on clip pressed against the contactsprings.C. Close the cover, then press the test button for about 5seconds until the horn sounds two sequences of a loud3-beep alarm. This means that the smoke detectionsection is working properly.2.5 Resetting the Transmitter Moduleand Enrolling its PowerCode IDA rear tamper protection switch ismounted under the PC board.The tamper switch actuator,extending through a hole in thebase (see Figure 4), is pressedagainst the bracket when the unitis attached to the bracket.Removal of the unit from thebracket will cause the switchcontacts to open, creating atamper event, which will bereported by the transmitter to thecontrol panel.Battery cover Figure 4. Rear TamperRefer to the control panel’s installation instructions and follow theprocedure given there for enrolling transmitter IDs in the controlpanel's memory. When required to initiate a transmission forenrollment, press the smoke detector’s test button until the built-inhorn sounds, or press the tamper switch.Note: It is much easier to carry out this operation while holdingthe MCT-425 in your hand, close to the control panel.2.6 Mounting the Bracket in PlaceRead Section 4 in this manual first, then decide where to install adetector.

DE3642 34. SMOKE DETECTOR INSTALLATION OVERVIEW4.1 Where to Install Smoke DetectorsSmoke detectors should be installed in accordance with theNFPA Standard 74 (National Fire Protection Association,Batterymarch Park, Quincy, MA 02169). For complete coveragein residential units, smoke detectors should be installed in allrooms, halls, storage areas, basements and attics in each familyliving unit. Minimum coverage is one detector on each floor andone in each sleeping area. For maximum protection, a smokedetector should be located outside primary sleeping areas or oneach level of your home. Here are a few useful tips for you: • Install a smoke detector in the hallway outside every separatebedroom area, as in Figure 8. Two detectors are required inhomes with two bedroom areas, as in Figure 9. • Install a smoke detector on every floor of a multi-floor home orapartment, as shown in Figure 10. • Install a minimum of two detectors in any household. • Install a smoke detector inside every bedroom. • Install smoke detectors at both ends of a bedroom hallway ifthe hallway is more than 12 meters (40 feet) long. Figure 8. Locations for Placing Smoke Detectors in a SingleResidence with only One Sleeping Area • Install a smoke detector inside every room where one sleepswith the door partly or completely closed, since smoke could beblocked by the closed door and a hallway alarm may not wakeup the sleeper if the door is closed.Figure 9. Locations for Placing Smoke Detectors in Single-FloorResidence with More than One Sleeping Area.Figure 10. Placing Smoke Detectors in a Multi-Floor Residence • Install basement detectors at the bottom of the basementstairwell. • Install second-floor detectors at the top of the first-to-secondfloor stairwell. • Be sure no door or other obstruction blocks the path of smoketo the detector. • Install additional detectors in your living room, dining room,family room, attic, utility and storage rooms. • Install smoke detectors as close to the center of the ceiling aspossible. If this is not practical, put the detector on the ceiling,at least 10 cm (4 inches) away from any wall or corner, asshown in Figure 11. • If ceiling mounting is not possible and wall mounting ispermitted by your local and state codes, put wall-mounteddetectors between 10 - 15 cm (4 - 6 inches) from the ceiling,also see Figure 11. • If some of your rooms have sloped, peaked, or gabled ceilings,try to mount detectors 0.9 meter (3 feet) measured horizontallyfrom the highest point of the ceiling as shown in Figure 12.Figure 11. Recommended Bestand Acceptable Locations toMount Smoke DetectorsFigure 12. RecommendedLocation to Mount SmokeDetectors in Rooms withSloped, Gabled or PeakedCeilingCAUTION (As required by the California State FireMarshall)"Early warning fire detection is best achieved by theinstallation of fire detection equipment in all roomsand areas of the household as follows:(1) A smoke detector installed in each separate sleeping area (inthe vicinity, but outside the bedrooms), and (2) Heat or smokedetectors in the living rooms, dining rooms, bedrooms, kitchens,hallways, attics, furnace rooms, closets, utility and storage rooms,basements and attached garages."For your information, NFPA Standard 74, Section 2-4 reads asfollows:"2-4.1.1 Smoke detectors shall be installed outside each separatesleeping area in the immediate vicinity of the bedrooms and oneach additional story of the family living unit including basementsand excluding crawl spaces and unfinished attics.The provisions of 2-4.1.1 represent the minimum number ofdetectors required by this standard. It is recommended that thehouseholder consider the use of additional smoke detectors forincreased protection for those areas separated by a door from theareas protected by the required smoke detectors under 2-4.1.1above. The recommended additional areas are living room,dining room, bedroom(s), kitchen, attic (finished or unfinished),furnace rooms, utility room, basement, integral or attachedgarage, and hallways not included in 2-4.1.1 above. However, theuse of additional detectors remains the option of thehouseholder." We recommend complete coverage and use ofadditional smoke detectors.4.2 Where to Install Smoke Detectorsin Mobile Homes and RVsMobile homes and RVs built after about 1978 were designed andinsulated to be energy-efficient. In mobile homes and RVs builtafter 1978, smoke detectors should be installed as describedabove. Older mobile homes and RVs may have little or noinsulation compared to current standards. Outside walls and roofsare often made of non-insulated metal, which can transferthermal energy flow from outdoors. This makes the air right nextto them hotter or colder than the rest of the inside air. Theselayers of hotter or colder air can keep smoke from reaching asmoke detector. Therefore, install smoke detectors in such unitsonly on inside walls. Place them 10 ~ 15 cm (4 to 6 inches) fromthe ceiling. If you are not sure how much insulation is in yourmobile home or RV, then install the detector on an inside wall. Ifthe walls or ceiling are unusually hot or cold, then install thedetector on an inside wall. Install one detector as close to thesleeping area as possible for minimum security, or install onedetector in each room for more security. Before you install anydetector, please read the following section on "Where Not toInstall Smoke Detectors.”
4DE36424.3 Where Not to Install SmokeDetectorsFalse alarms occur when smoke detectors are installed wherethey will not work properly. To avoid false alarms, do not installsmoke detectors in the following situations: • Combustion particles are by-products of something burning. Donot install smoke detectors in or near areas where combustionparticles are present, such as kitchens with few windows orpoor ventilation, garages where there may be vehicle exhaust,near furnaces, hot water heaters and space heaters. • Do not install smoke detectors less than 6 meters (20 feet)away from places where combustion particles are normallypresent, like kitchens. If a 20-foot distance is not possible, e.g.in a mobile home, try to install the detector as far away from thecombustion particles as possible, preferably on the wall. Toprevent false alarms, provide good ventilation in such places.IMPORTANT: Never try to avoid false alarms by disabling thedetector. • Do not mount smoke detectors in the path of fresh air intake.The flow of fresh air in and out can drive smoke away from thesmoke detector; thus reducing its efficiency. Figure 13 indicatesthe correct and incorrect locations concerning this problem. • Near pain thinner fumes. • In close proximity to an automobile exhaust pipe; this willdamage the detector. • In damp or very humid areas or near bathrooms with showers.Moisture in humid air can enter the sensing chamber, thenturns into droplets upon cooling, which can cause false alarms.Install smoke detectors at least 3 meters (10 feet) away frombathrooms. • In very cold or very hot areas, including unheated buildings oroutdoor rooms. If the temperature goes above or below theoperating range of smoke detector, it will not work properly.The temperature range for your smoke detector is 4°C to 38°C(40°F to 100°F). • In very dusty or dirty areas, dirt and dust can build up on thedetector's sensing chamber, to make it overly sensitive.Additionally, dust or dirt can block openings to the sensingchamber and keep the detector from sensing smoke. • Near fresh air vents or very drafty areas like air conditioners,heaters or fans. Fresh air vents and drafts can drive smokeaway from smoke detectors. • Dead air spaces are often at the top of a peaked roof, or in thecorners between ceilings and walls. Dead air may preventsmoke from reaching a detector. See Figures 11 and 12 forrecommended mounting locations. • In insect-infested areas. If insects enter a detector's sensingchamber, they may cause a false alarm. Where bugs are aproblem, get rid of them before putting up a detector. • Near fluorescent lights, electrical "noise" from fluorescent lightsmay cause false alarms. Install smoke detectors at least 1.5meters (5 feet) from such lights.Figure 13. Recommended Smoke Detector Locations to Avoid AirStreams with Combustion ParticlesWARNING: Never remove batteries to stop a false alarm. Open awindow or fan the air around the detector to get rid of the smoke.The alarm will turn itself off when the smoke is gone. If falsealarms persist, attempt to clean the detector as described in thismanual.WARNING: Do not stand close to the detector when the alarm issounding. The alarm is loud in order to wake you in anemergency. Too much exposure to the horn at close range maybe harmful to your hearing.5. TAKING CARE OF THE MCT-4255.1 Battery ReplacementThe MCT-425 is designed to be as maintenance-free as possible.To keep the smoke detector in good working order, you must test itweekly, as instructed in Para. 6.1 below.Make sure to test detectors mounted within RVs in storage beforeeach trip, and at least once each week during use.Make it a rule to replace the detector’s battery (alkaline) once ayear even if there is no indication that the battery is weak. Alsobe sure to replace it immediately upon reception of a low batterymessage via your control panel.If you disregard this message, an audible reminder in the formof once-per-minute "beep" will sound after a few days. Thelow-battery "beep" should last at least 30 days before thebattery dies out completely.NOTE: For best performance, use only alkaline or lithiumbatteries as replacement batteries. Carbon zinc batteries are notacceptable. Alkaline batteries can be purchased at any retailstore that sells batteries. The following alkaline 9V batteries areacceptable for proper operation: Eveready #522, #1222, #216;Duracell #MN1604; or Gold Peak #1604P, #1604S.Replace the battery as follows:A. Grasp the detector’s body with your hands, rotate it slightlycounterclockwise and pull it off the wall-mounted bracket.B. Turn the unit over and remove the screw from the batterycover (see Figure 3).C. Remove the old battery from the snap-on battery clip, thenconnect the new battery, paying close attention to correctpolarity. Then, push the battery into its holder.D. Close the cover, re-insert the screw, and test the unit asinstructed in Para. 2.6A.E. Re-mount the unit on the bracket as instructed in Para. 2.6B.5.2 CleaningIt is necessary to maintain the detector frequently to ensure itworking properly. Follow these tips for taking care of your detector: • Use a vacuum cleaner to clean the air vents occasionally tokeep them free of dust. (Before cleaning your unit, unplug itfrom the wall outlet.) • Push the Test button on your detector to test its operatingfunction weekly.NOTE: If false alarms keep occurring, check whether the detector'slocation is adequate (see Para. 4.1 and 4.2). Relocate the unit if it isnot located properly. Clean as described above.
DE3642 56. ADDITIONAL ADVICE6.1 Routine TestingThe detector should be tested weekly and also whenever yoususpect that it does not go into alarm. Push the test button firmlywith your finger until the horn sounds (it may take up to 20seconds). Also verify that the control panel responds to thetransmitted fire alarm. If the detector fails, have it repaired orreplaced immediately, to ensure that it works properly.WARNING: Never use an open flame of any kind to test yourdetector. You may set fire to damage the detector as well asyour home. The built-in test switch accurately tests alldetector functions, as required by Underwriters' Labora-tories. This is the only correct way to test the unit.NOTE: If the alarm horn produces a loud continuous sound andthe red LED flashes when you are not testing the unit, this meansthe detector has sensed smoke or combustion particles in the air.Verify that the alarm is a result of a possible serious situation,which requires your immediate attention. • The alarm could be caused by a false situation. Cookingsmoke or a dusty furnace, sometimes called "friendly fires" cancause the alarm to sound. If this happens, open a window orfan the air away to remove the smoke or dust. The alarm willturn off as soon as the air is completely clear. CAUTION: Do not disconnect the battery from the detector.This will remove your protection from fires. • If the alarm horn begins to beep once a minute, this signalmeans that the detector's battery is weak. Install a new batteryimmediately. Keep fresh batteries on hand for this purpose.6.2 Tips to Enhance Your ProtectionFrom FiresPutting up smoke detectors is only one step in protecting your familyfrom fires. You must also reduce the chances of fires starting in yourhome. You must also increase your chances of escaping safely if onedoes start. To have a good fire safety program you must apply thefollowing tips to enhance your family's protection from fires: A . Install smoke detectors properly. Carefully follow all theinstructions in this manual. Keep your smoke detectors cleanand test them every week. B . Remember that detectors that do not work will not alert you.Replace your smoke detectors immediately if they are notworking properly. C . Follow fire safety rules, and prevent hazardous situations: • Use smoking materials properly. Never smoke in bed. • Keep matches and cigarette lighters away from children. • Store flammable materials in proper containers. Never usethem near open flame or sparks. • Keep electrical appliances in good condition. Do not overloadelectrical circuits. • Keep stoves, fireplaces, chimneys, and barbecue grills greasefree. Make sure they are properly installed and away from anycombustible materials. • Keep portable heaters and open flames such as candles awayfrom combustible materials. • Do not allow rubbish to accumulate. • Keep a supply of extra batteries on hand for your batterypowered smoke detectors.D. Develop a family escape plan and practice it with your entirefamily. Be sure to include small children in your practice. • Draw a floor plan of your home, and find two ways to exit fromeach room. There should be one way to get out of eachbedroom without opening the door. • Explain to children what the smoke detector alarm signalmeans. Teach them that they must be prepared to leave thehome by themselves if necessary. Show them how to check tosee if doors are hot before opening them. Show them how tostay close to the floor and crawl if necessary. Show them howto use the alternate exit if the door is hot and should not beopened. • Decide on a meeting place which has a safe distance from yourhouse. Make sure that all your children understand that theyshould go and wait for you there if there is a fire. • Hold fire drills at least every 6 months, making sure that everyone,even small children, knows what to do to escape safely. • Know where to go to call the Fire Department outside your home. • Provide emergency equipment, such as fire extinguishers, andteach your family to use this equipment properly.6.3 More Tips on How to Face a Fire atHomeIf you have made an escape plan and practiced it with yourfamily, their chances of escaping safely are increased. Go overthe following rules with your children when you have fire drills.This will help everyone remember the rules in a real emergency. A . Don't panic and stay calm. Your safe escape may depend onthinking clearly and remembering what you have practiced. B . Get out of the house as quickly as possible. Follow a plannedescape route. Do not stop to collect anything or to getdressed. C . Feel the doors to see if they are hot. If they are not, openthem carefully. Do not open a door if it is hot. Use analternate escape route.D. Stay close to the floor. Smoke and hot gases rise. E . Cover your nose and mouth with a wet or damp cloth. Takeshort, shallow breaths. F . Keep doors and windows closed. Open them only if you haveto in order to escape. G . Meet at your planned meeting place after leaving the house. H . Call the Fire Department as soon as possible from outsideyour house. Give the address and your name. I . Never go back inside a burning building. Contact your localFire Department. They will give you more ideas about how tomake your home safer from fires and how to plan yourfamily's escape.7.
