RECOMMENDED LOCATION OF ALARMS

Locate the first smoke alarm in the immediate area of the bedrooms. Try to protect the escape route as the bedrooms are usually farthest from an exit. If more than one sleeping area exists, locate additional smoke alarms in each sleeping area. If a hall is more than 40 feet (12 meters) long, install a smoke alarm at each end
Locate additional smoke alarms to protect any stairway as stairways act like chimneys for smoke and heat.
Locate at least one smoke alarm on every floor level.
Locate a smoke alarm in any area where a smoker sleeps or where electrical appliances are operated in sleeping areas.
Smoke, heat and other combustion products rise to the ceiling and spread horizontally. Mounting the smoke alarm on the ceiling in the center of the room places it closest to all points in the room. Ceiling mounting is preferred in ordinary residential construction. However, in mobile homes, wall mounting on an inside partition is preferred to avoid the thermal barrier that may form at the ceiling.
When mounting smoke alarm on a wall, if local codes allow, use an inside wall with the top edge of the smoke alarm a maximum of 12″ (30.5cm) below the ceiling/wall intersections (See Diagram A).

Instructions of Usielectric Smoke & Fire Alarm 5304L

Existing Homes
The NFPA requires a smoke alarm on every level and outside each sleeping area in existing construction. An existing household with one level and one sleeping area is required to have one smoke alarm.
New Construction Homes and Manufactured Homes
The NFPA requires AC-powered, interconnected smoke alarms to be installed inside each bedroom, outside each bedroom area, and on every level of the home. They also require a minimum of two AC-powered, interconnected smoke alarms in any new construction home.

Sloped Ceilings (Peaked Ceilings)
Smoke alarms or smoke detectors mounted on a peaked ceiling shall be located within 36 in. (914 mm) horizontally of the peak, but not closer than 4 in. (102 mm) vertically to the peak.
Sloped Ceilings (Shed Ceilings)
Smoke alarms or smoke detectors mounted on a sloped ceiling having a rise greater than 1 ft. in 8 ft. (1 m in 8 m) horizontally shall be located within 36 in. (914 mm) of the high side of the ceiling, but not closer than 4 in. (102 mm) from the adjoining wall surface.
Tray-Shaped Ceilings
Smoke Alarms or smoke detectors shall be installed on the highest portion of the ceiling or on the sloped portion of the ceiling within 12 in. (305 mm) vertically down from the highest point.
Mobile Home Installation
For minimum protection, smoke alarms should be installed in compliance with H.U.D. Manufactured Home Construction Safety Standards, Title 24 CFR, Section 3280.208 and Section 3282. For additional protection, see Single Story Residence smoke alarm requirements/recommendations for Existing Homes and New Construction Homes.
Note: For mobile homes built before 1978, install smoke alarms on inside walls between 4” and 12” from the ceiling (older mobile homes have little or no insulation in the ceiling). This is especially important if the ceiling is unusually hot or cold.
Install a smoke alarm inside each bedroom and in the hallway outside each separate sleeping area.

AVOID THESE LOCATIONS

the garage – products of combustion are produced when you start your vehicle.
near appliances or areas where normal combustion regularly occurs (kitchens, near furnaces, gas hot water heaters). Use smoke alarms with photoelectric sensors or smoke alarms with Silence Feature for these areas.
in areas with high humidity, like bathrooms or areas near dishwashers or washing machines. Install at least 3 feet (0.9 meters) away from these areas.
in areas of turbulent air such as air returns or heating and cooling supply vents, smoke alarms shall not be located where airflow prevents smoke from reaching the alarms.
in extremely dusty, dirty or insect-infested areas. Loose particles interfere with smoke alarm operation.
in areas where temperature may fall below 40 0 F (4.4 0 C) or rise above 100 0 F (37.8 0 C).
closer than 1 foot (0.3m) from fluorescent lights, electrical “noise” and flickering may affect the alarm’s operation.
closer than 3 feet (0.9m) horizontal path from the tip of the blade of a ceiling suspended (paddle) fan.
on a poorly insulated ceiling or exterior wall (mount smoke alarm on an inside wall).

Wiring Instructions of Usielectric Smoke & Fire Alarm 5304L

The appropriate power supply is 120 Volt single phase power supplied from a nonswitch able circuit NOT protected by a ground fault circuit interrupter.
- Turn off AC power to the circuit before wiring the smoke alarm.
- There are three pigtail wires (black, white and yellow) coming from the AC QUICK CONNECTOR. The proper wire connection is as follows:
WIRES FROM QUICK CONNECTOR CONNECT TO:
- BLACK "HOT" side of AC line
- WHITE "NEUTRAL" side of AC line
- YELLOW Interconnect wires of other smoke alarms

CAUTION! DO NOT TAMPER WITH WIRES WHEN POWER IS ON!
For alarms that are used as single smoke alarms, do not connect the yellow wire to anything. Insulate this wire (tape it) in place to make certain the yellow wire cannot contact any metal parts.

INTRCONNECTION & COMPATIBILITY

Interconnected alarms can provide earlier warning than stand-alone alarms, especially if a hazard is present in a remote area of the dwelling. When alarms are interconnected, all alarms will sound when the initiating alarm sounds, providing more time to escape safely. This alarm may be interconnected with a total of not more than 24 interconnected devices, i.e. as many as 11 other USI Electric or Universal brand model smoke alarms or combination smoke and carbon monoxide (CO) alarms or smoke and carbon monoxide/natural gas alarms; 6 other initiating alarms which may be a combination of USI Electric or Universal brand CO alarms and heat alarms; and 6 other non-initiating devices such as USI Electric brand relays.
This alarm can be interconnected with the following compatible alarms:

MDSCN111, MICN109, MCN108, SS-2895, USI-1103, USI-1204, USI-1208, USI-1209, USI-5204, USI-3204, USI-7795, 5304, MI106, MDS107, MP117, USI-2430, USI-960, MI106S, MIC1509S, MPC122S, MP116S, SLW127, AMIC1510S, AMI1061S.

When any one of these interconnected models goes into alarm, it will trigger the corresponding alarm within the interconnected system with respect to their sensing capabilities.
Interconnected CO alarms, or the CO alarm circuit of combination smoke, CO and natural gas alarms, will only respond if a CO alarm event initiates the alarm. All other alarms remain silent.
Interconnected combination CO and natural gas alarms will only respond if a natural gas event initiated the alarm. All other alarms remain silent. Natural gas detection is only present in models MDSCN111, MICN109, MCN108; therefore, a natural gas alarm will NOT trigger the alarm of non-natural gas sensing models within an interconnected system.

The following alarms can trigger Quick Find® Alarm Origination, but will not indicate Alarm Origination on an interconnected system:
USI-1103, USI-1204, USI-1208, USI-1209, USI-1213, USI-5204, USI-3204, USI-2430, USI-7795.
The following alarms cannot be reset through an interconnected system because they do not have Quick Find Alarm Origination:
USI-1103, USI-1204, USI-1208, USI-1209, USI-5204, USI-3204, USI-2430, USI-7795.
Interconnected smoke alarms, heat alarms and relays will only respond if a smoke alarm event or heat alarm event initiates the alarm. All CO and natural gas alarms remain silent.
NOTE: Alarms without battery backup will not respond during an AC power failure.
NOTE: The relay, model USI-960, will not respond if a CO or natural gas alarm event initiates the alarm.

USi ELECTRIC 5304 Smoke and Fire Alarm - 5

The yellow wire is used only for interconnect (multiple station operations) USI Electric or Universal model alarms. Connecting this yellow wire to any other circuits may result in damage and alarm malfunction. All interconnect alarms must be powered from a single circuit.
If local codes do not specify, be sure the neutral wire is common to all alarms. The maximum wire run distance between the first and last alarm/device in an interconnected system is 1,000 feet. NOTE: Use standard household wire, 18 gauge or larger, rated at least 300V, as required by local codes. This wire is commonly available at most electrical supply and hardware stores. The resistance of the interconnect wiring shall be a maximum of 10 Ohms.
The alarm wiring shall be in accordance with the provisions of Articles 210 and 300.3(B) of the National Electrical Code, ANSI/NFPA 70. According to the NFPA 72 / Ed. 2013; paragraph 29.6.3 Household Fire Alarm Systems /AC Primary Power Source: “AC primary (main) power shall be supplied either from a dedicated branch circuit or the un-switched portion of a branch circuit also used for power and lighting.”.

OPERATION, TESTING & MAINTENANCE

OPERATION: The smoke alarm is operating once the AC power is connected and turned on (the battery must also be installed). When products of combustion are sensed, the alarm sounds a loud alarm which continues until the air is cleared.
This alarm incorporates the NFPA recognized horn signal for evacuation. During alarm mode, the horn produces three beeps followed by a two second pause and then continually repeats.
READY/ACTIVE CONDITION
The red LED blinks on once approx. every 40-45 seconds to indicate the alarm is properly functioning.
LOCAL ORIGINATING ALARM CONDITION
The red LED blinks on approx. every 2 seconds and the alarm emits a loud, pulsating alarm sound.
NON-ORIGINATING ALARM CONDITION
The red LED is off and the alarm emits a loud, pulsating alarm.
GREEN LED
The green LED is on whenever AC power is turned on.
NUISANCE ALARMS
The smoke alarm is designed to minimize nuisance alarms. Smoking will not normally set off the alarm unless smoke is blown directly into the smoke alarm. Combustion particles from cooking may set off the alarm if the smoke alarm is located close to the kitchen cooking surface. Large quantities of combustion particles are generated from spills or broiling. If the smoke alarm does sound, check for fires first. If a fire is discovered, get out and call the fire department. If no fire is present, check to see if one of the reasons listed above may have caused the alarm. Use the Silence Feature if it is a nuisance alarm, or reset the alarm by pressing and holding the test button for ten seconds.
- NOTE: It is best to “reset” the alarms before initial test is performed. See RESET procedures below.
TESTING
Test by pushing the Test button on the smoke alarm cover until the alarm sounds, then release. The alarm sounds if all electronic circuitry, horn and battery are working. If no alarm sounds, the alarm may have a power supply failure. Test the smoke alarm weekly to assure proper operation.
ALARM ORIGINATION
Patented Quick Find® Alarm Origination—In an interconnected system consisting of any of these models: MI106S, MIC1509S, MPC122S, MP116S, 5304, MI106, MDS107, MCN108, MICN109, MDSCN111, MP117, it may be difficult to determine which alarm initiated the alarms to sound during an alarm event. This Quick Find feature will immediately allow you to locate the originating alarm once the alarms have stopped sounding.
RESET: To reset the QUICK FIND ® Alarm Origination condition, press and hold the Test button on any alarm for at least 10 seconds and then release. Reset after each alarm. The reset feature will reset all interconnected units.

WARNING!
NEVER use an open flame of any kind to test this smoke alarm. You might accidentally damage or set fire to the smoke alarm or to your home. The built-in test switch accurately tests the smoke alarm’s operation as required by Underwriters Laboratories Inc. (UL).

The Go/No-Go test for this smoke and fire alarm is to use one of the following UL listed can-type aerosol smoke alarm testers. The instructions for use are printed on the canister. Home Safeguard, Model 25S.
CAUTION! If you choose to use an aerosol smoke product to test the smoke alarm, be certain to use one that has been Listed to Underwriters Laboratories, Inc. Safety Standards and use it only as directed. Use of non-UL Listed products or improper use of UL Listed products may affect the smoke alarm’s sensitivity.

NUISANCE ALARM SILENCE FEATURE

This feature is to be used only when a known alarm condition, such as smoke from cooking, activates the smoke alarm. The smoke alarm Silence Feature is activated by pushing and releasing the Silence button on the smoke alarm cover while in alarm condition. The smoke alarm will automatically reduce sensitivity and the red LED will blink on approx. every 10 seconds to indicate the alarm is in the Silence mode. The smoke alarm will gradually regain normal sensitivity and sound the alarm if particles of combustion are still present. The Silence feature may be used repeatedly until the air has cleared, by pushing and releasing the Silence button again. Resetting the smoke alarm after a nuisance alarm is recommended.
NOTE: If the Test button is pressed and held during the Silence mode, the smoke alarm will be tested normally. Upon the release of the Test button, the Silence mode will be restarted. Before using the alarm Silence Feature, identify the source of smoke and be certain that safe conditions exist.

(UTHA) MAINTENANCE

The smoke alarm is virtually maintenance free. However, under dusty conditions, a vacuum hose may be used to clear the sensing chamber of dust.
Clean the smoke alarm at least once a month to remove dust, dirt, insects or debris. Always turn off power to smoke alarm before cleaning. Using a soft brush or wand attachment to a vacuum cleaner, vacuum all sides and cover of smoke alarm.
Be sure all the vents are free of debris.
If the smoke alarm is false alarming and cannot be restored to normal operation, the smoke alarm should be replaced.

BACKUP BATTERY REPLACEMENT

DEVELOP AND PRACTICE A PLAN OF ESCAPE

BASICS OF ESCAPE PLAN

Make a floor plan indicating all doors and windows and at least two escape routes from each room. Second story windows may need a rope or chain ladder.
Have a family meeting and discuss your escape plan, showing everyone what to do in case of fire.
Determine a place outside your home where all of you can meet if a fire occurs.
Familiarize everyone with the sound of the smoke alarm and train them to leave your home when they hear the sound.
Identify children’s bedrooms with red stickers placed in the upper left corner of the windows. They are available from your local fire department.
Practice a fire drill at least every six months. Practice allows you to test your plan before an emergency. You may not be able to reach your children. It is important they know what to do!

WHAT TO DO WHEN THE ALARM SOUNDS

Leave immediately by your plan of escape. Every second counts, so don’t waste time getting dressed or picking up valuables.
In leaving, don’t open any inside door without first feeling its surface. If hot, or if you see smoke seeping through cracks, don’t open that door! Instead, use your alternate exit. If inside door is cool, place your shoulder against it, open it slightly and be ready to slam it shut if heat and smoke rush in.
Stay close to the floor if air is smoky. Breathe shallowly through a cloth, wet if possible.
Once outside, go to your selected meeting place and make sure everyone is there.
Call the fire department from your neighbor’s home – not from yours!
Don’t return to your home until fire officials say that it is all right to do so.

CAUTION: (AS REQUIRED BY THE CALIFORNIA STATE FIRE MARSHAL)

Early warning fire detection is best achieved by the installation of fire detection equipment in all rooms and areas of the household as follows. A smoke alarm installed in each separate sleeping area (in the vicinity of, but outside of the bedrooms), and heat or smoke detectors in the living rooms, dining rooms, bedrooms, kitchens, hallways, attics, furnace rooms, closets, utility and storage rooms, basements and attached garages.
