Recommended Locations for your Heat Alarm

Hallways. A Heat alarm is required to be centrally located outside of each sleeping area, and on every level of the home.

If your hallway is longer than 40 feet, install a

Heat alarm at both ends.

Bedrooms.

A major threat from poisonous

Heat occurs at night when people are sleeping. For added protection, Heat alarms can be installed in all sleeping rooms.

Basements. A Heat alarm should be located on every level of the house, including the basement.

Living Spaces.

To enhance safety, a Heat alarm can be located in the living spaces of a home.

Recreation and Dining Rooms. For additional protection, a Heat alarm can be located in the other living spaces of the home.

Note: Applicable building codes or other local laws may require the installation of additional CO and fire alarms in addition to the minimum recommended by this manual.

7

Areas Not Appropriate for Heat Alarms

Kitchens. Do not install within 5 feet

(1.5m) of kitchen appliances. The by- products of cooking food can effect the performance of the Heat alarm.

Garages. Do not install in garages.

Heat Alarm Features and Functions

Power Indicator Light (Green)

On the EX20-HT, the POWER icon will briefly flash once per minute when the alarm has been activated.

Fire Warning Light (Red)

WARNING will flash rapidly when a Heat alarm detects sufficient levels of heat. This will be accompanied by the 3-beep sounding of the horn.

Radio Networking Light (Blue)

RADIO will flash once per second to indicate the multiLINX network is open to accept additional alarms into the network.

RADIO will cease to flash one minute after all new alarm additions have occurred.

Warning Light (Red)

WARNING will flash red once per minute accompanied by the horn chirp to indicate that the alarm has reached the end of its useful life. Replace the alarm.

WARNING can also be activated by a remote signal from a CO alarm. In this case, WARNING will be solid red accompanied by 4 beeps of the horn.

10

Heat Alarm Features and Functions

End of Life Signal (Red)

The EX20-HT has been designed to last a minimum of ten years. When the alarm has reached the end of its useful life, the End of Life Signal will occur.

This is triggered when the heat sensor is no longer working properly or the battery power has been depleted.

In this case, the WARNING light will flash red once per minute accompanied by the horn chirp.

When the End-of-Life Signal occurs, follow the deactivation procedure on Page 12, and replace alarm.

Testing the Heat Alarm

Every Heat alarm should be tested at least weekly to ensure proper operation.

To test the alarm, press and release the button on the front face.

The alarm will sound with 3 beeps and the FIRE icon will flash red rapidly.

All four icons will strobe to indicate a successful test.

The alarm will then send out a network test command and all other alarms on the multiLINX network will perform the same internal test.

If the alarm fails the self-test, the horn will sound a single long tone. If this occurs, replace the alarm.

Silencing Nuisance Alarms

The EX20-HT alarm is equipped with a silence feature that can silence the alarm.

If during normal operation the alarm is triggered, and all appropriate safety precautions are being taken, the alarm can be silenced for ten minutes by pressing the button on the front face of the unit.

The silence feature will also silence any alarms that were triggered remotely. However, the initiating alarm must be silenced directly.

Creating Your multiLINX Network

The EX20-HT Alarm communicates on its own private multiLINX network. This network is created simply by powering up new alarms one at a time.

Activate your first alarm by moving the slide switch located on the back side of the alarm in the direction indicated by the arrow.

The switch will lock into place. This allows the alarm to be mounted to its bractet

General Note: It is easiest to first create the multiLINX network while all alarms are located together, such as on a table.

The blue RADIO light will begin to flash slowly.

While the blue RADIO light is flashing at this rate, additional alarms may be added to your network.

Note: This switch is connected to a lock-out mechanism that will prevent installation on the bracket until activated.

Activate your next alarm by moving its slide switch as shown above.

The blue RADIO light will flash briefly, then the alarm will chirp twice and all four of the lighted icons will strobe on in succession.

This alarm has been added to your network!

Continue activating each new alarm, one alarm at a time, until all alarms have been added to the network. This should include smoke and heat alarms as well.

One minute after activating the last alarm, the

RADIO light will stop flashing on the original alarm, and it will join the network. The network is now closed.

General Note: The multiLINX network is limited to 18 total units. Only 12 of these units may be smoke alarms, the remaining units can be CO and heat alarms

13

Adding an Alarm to Your multiLINX Network

To add an alarm(s) to an existing multiLINX network, perform the following steps.

Select any alarm on the existing network. Press and hold the button on the front cover of the alarm. The red WARNING or FIRE light will flash rapidly and the alarm will sound four tones.

Continue holding the button down.

Next, the yellow WARNING light will flash slowly.

Count to 5 flashes of the yellow WARNING light and release the button.

If done correctly, the blue RADIO light will now slowly pulse, indicating the network is again ready to receive additional alarms.

If not, wait about 15 seconds and carefully repeat these steps.

To add a new alarm, simply slide the switch located on the back side of the alarm in the direction indicated by the arrow. It will lock into place when fully positioned.

If the alarm being added was previously used, follow the steps on Page 13 to erase its multiLINX data. Then re-open this alarm’s radio networking using steps 1-2 in this section.

The blue RADIO light will flash briefly, then the alarm will chirp twice and all four of the lighted icons will strobe on in succession.

The alarm has been successfully added to your network!

After one minute, the RADIO light will stop flashing on the original alarm and the network will again close.

14

Removing an Alarm from a multiLINX Network

In the event that an alarm must be removed from your network, the alarm’s multiLINX data must be erased.

Press and hold the button on the front cover of the alarm. The red WARNING light will flash rapidly and the alarm will sound four tones.

Continue holding the button down.

Next, the WARNING light will begin to flash yellow. Count 10 flashes of the yellow

WARNING light and release the button.

The alarm will chirp twice and all four of the lighted icons will strobe on.

Important Fire and Emergency Safety Information

Be prepared for fire emergencies:

Plan Your Escape

• Draw a floor plan of your home.

• Show two ways out of each room.

• Discuss escape routes with everyone in your home.

• Agree on an outside meeting place where you’ll gather after escaping.

Be Prepared

• Familiarize every member of the household with the sound of the smoke and heat alarms.

• Have everyone in the home memorize the fire department’s emergency phone number.

• Instruct each person to call the emergency number from a neighbor’s phone or a mobile phone used outside the home.

• Teach everyone to unlock and open all windows, and release security bars.

• Make sure security bars are equipped with quick-release devices.

• Keep exits clear and free from furniture and clutter.

Practice!

• Hold home fire drills at least twice a year.

Get Out and Stay Out

• Once you’ve escaped from a fire, do not go back inside for any reason.

• Make fire drills realistic by pretending some escape paths are blocked by smoke or fire.

If you live in an apartment building

• Learn and practice your building’s evacuation plan.

• If you hear a fire alarm, react immediately.

• Know the location of all building exits and fire alarm boxes.

• Use the stairs ... never use an elevator during a fire.

• If exits are locked or blocked, report the problem to your building’s management.

Escape Tips

• Close doors behind you as you escape to slow the spread of fire and smoke.

• If you have to escape through smoke, crawl on your hands and knees, keeping your head one to two feet above the floor, where the air will be clearest.

• Test the doorknob and spaces around the door with the back of your hand. If the door is warm, try another escape route. If the door is cool, open it slowly.

Close it quickly if smoke pours through.

WARNING! Limitations of Heat alarms

Wireless Heat alarms have been proven to be both effective and reliable, but they may not be effective under all conditions. No alarm design can offer total protection of life and property. A Heat alarm is not a substitute for an adequate homeowner’s property insurance or life insurance policy.

WARNING - This product is intended for use in ordinary indoor locations of family living units. It is not designed to measure compliance with Occupational Safety and Health Administration (OSHA) commercial or industrial standards.

Heat alarms will not work without a source of power. The alarm will not operate and the alarm will not sound if the battery has died or the alarm has been deactivated.

CAUTION - This alarm will only indicate the presence of Heat at the sensor. Heat may be present in other areas.

Radio communication between alarm units may fail to take place if significant changes to the home have occurred since installation and testing. Moving large objects such as a refrigerator or metal cabinet could impede alarm radio performance.

Alarm warning signals may not be heard. A deep sleeper, hearing-impaired person, young child or someone impaired by drugs or alcohol may not awaken in response to an alarm activation. This can occur even when an alarm is located inside the individual’s bedroom. Be sure emergency exit drills are practiced that take this possibility into account.

Heat alarms may not always activate and provide early enough warning. A Heat alarm will only activate when it is maintained in working order and sufficient amounts of Heat reaches the unit.

Heat ALARMS CAN NOT GUARANTEE THAT YOU WILL NEVER SUFFER ANY ILLNESS

OR INJURY FROM EXPOSURE TO Heat .

Indiviuals with medical problems may consider using warning devices which provide audible and visual signals for Heat concentrations under 30ppm.

This device is designed to protect individuals from the acute effects of Heat exposure. It will not fully safeguard individuals with specific medical conditions.

If in doubt consult a medical practitioner.

WARNING - The installation of Heat alarms should not be used as a substitute for proper installation, use, and maintenance of fuel-burning appliances, including appropriate ventilation and exhaust systems.
