Bedrooms. A major threat from fire occurs
at night when people are sleeping. Smoke
alarms are required protection in all sleeping
rooms.

Living Rooms. To enhance safety, a smoke
alarm should be located in the living room of
a home.

Recommended Locations for your Smoke Alarm

Recreation and Dining Rooms. For

additional protection, a smoke alarm can
be located in the other living spaces of the
home.

Hallways. A principal threat to people
sleeping in bedrooms comes from fires
elsewhere in the home. A smoke alarm
is required to be located outside of each
sleeping area, and on every level of the home.

Basements. A smoke alarm is required
on every level of the house, including the
basement near the stairway leading to the
floor above.

Areas Not Appropriate for Smoke Alarms

Kitchens. Do not install near kitchen

appliances. Steam and by-products of
cooking might cause nuisance alarms.

Garages. Do not install in garages.
Exhaust gases from vehicles can trigger
the smoke alarm.

Attics. Do not install in attics. A
smoke alarm can be affected by dust,
small insects or high temperatures. Do
not install the alarm in areas where
the normal ambient temperature can
exceed 100°F (38°C).

Utility and Furnace Rooms. Do not
install close to equipment that can create
steam and gas. Steam and gas can
trigger the smoke alarm.

National Fire Protection Association Standards

This equipment should be installed in accordance with the National Fire
Protection Association’s Standard 72 (National Fire Protection Association,
Batterymarch Park, Quincy, MA 02269).

For your information, the National Fire Protection Association’s Standard 72,
2013 Edition, Section 29.5.1 covering required protection in One- and Two­Family Dwelling Units, reads as follows:

29.5.1.1 Required Detection. Where required by other governing laws, codes,
or standards for a specific type of occupancy, approved single- and multiple­station smoke alarms shall be installed as follows:

(1) In all sleeping rooms and guest rooms.

(2) Outside each separate dwelling unit sleeping area, within 21 ft (6.4 m) of

any door to a sleeping room, with the distance measured along a path
of travel.

(3) On every level of the dwelling unit, including basements.

(4) On every level of a residential board and care occupancy (small facility),

including basements and excluding crawl spaces and unfinished attics.

(5) In the living area(s) of a guest suite.

(6) In the living areas(s) of a residential board and care occupancy (small

facility).

A.29.5.1 (NFPA 72 2013 Edition) “Are More Smoke Detectors Desirable?

The required number of smoke detectors might not provide reliable early
warning protection for those areas separated by a door from the areas protected
by the required smoke detectors. For this reason, it is recommended that the
householder consider the use of additional smoke detectors for those areas for
increased protection. The additional areas include the basement, bedrooms,
dining room, furnance room, utility room, and hallways not protected by the
required smoke detectors. The installation of smoke detectors in kitchens,
attics (finished or unfinished), or garages is not normally recommended as
these locations occasionally experience conditions that can result in improper
operation.”

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

Acceptable multiLINX Alarm Spacing

Each alarm will also act as a repeating
station, so any signal received by an alarm
will be rebroadcast.

After final installation, test all alarms
for proper multiLINX radio connection.
Simply press and release the test
button of an alarm while having a
helper observe the remote alarms.

Maximum
Spacing in
Open Area

200’ (70m)

The multiLINX network communicates using
radio frequencies 905.2MHz - 911.2MHz. The
range of the radio has been tested to 200 feet
(70m) in open area distance testing.

Exigent Sensors recommends complete home fire protection. This can
be achieved by installing a combination of smoke, CO and heat alarms in
their appropriate locations in every room of the house.

Alarm Features and Functions

Power Indicator Light (Green)

On the EX20 SMK (battery-only powered), the POWER
icon will briefly flash every 30 seconds when the
alarm has been activated.

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

Radio Networking Light (Blue)

Warning Light (Yellow)

WARNING will flash yellow every 30 seconds,
accompanied by the horn chip to indicate the smoke
chamber needs to be removed and cleaned.

FIRE will flash when the alarm detects sufficient
quantities of smoke or heat. This is accompanied by the
sounding of the horn.

FIRE will stay on continuously if the alarm was triggered
remotely by another alarm on the multiLINX network.

Fire Warning Light (Red)

RADIO will cease to flash one minute after the last alarm
has been added to the network or immediately after the
button has been pressed.

On the EX20-AC SMK (AC with battery backup), the
POWER icon will run continuously while AC powered.

FIRE will continue to flash twice per minute (without the
horn) for three days after exiting an alarm condition, or
until the front button has been pressed and released.

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.

Warning Light (Red)

WARNING will flash red every 30 seconds
accompanied by the horn chirp, for a minimum of 7
days, to indicate Low Battery. Replace the alarm.

WARNING will double flash red every 30 seconds
accompanied by the horn chirp, to indicate that the
alarm’s smoke sensor has reached its End-of-Life.
Replace the alarm.

Silencing Nuisance Alarms

Alarm Features and Functions

Testing the Alarm

Every alarm should be tested 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 FIRE will flash
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 network will
perform the steps above.

If the alarm fails, the horn will sound. Clean the
alarm (as described in this manual) and retest. If the
alarm still fails, contact the manufacturer.

The Exigent family of alarms is equipped with a silence feature that will decrease
the sensitivity of the alarm and silence nuisance alarms.

If in the course of normal activity, cooking smoke,
steam or other gases cause the alarm to activate,
the alarm can be silenced for ten minutes by
pressing the button on the front face of the
alarm.

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

If the quantity of smoke is too great, the
alarm will not silence until the air has
cleared sufficiently.

Creating Your multiLINX Network

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

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.

The blue RADIO light will begin to flash slowly.

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

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

This alarm has been added to
your network!

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

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.

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

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

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

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 FIRE light (WARNING if CO alarm)
will flash rapidly and the alarm will sound three
tones.

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.

The alarm has been successfully added to
your network!

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

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.

Continue holding the button down.

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

If the alarm being added was previously used,
follow the steps on Page 14 to erase its multiLINX
data. Then re-open this alarm’s radio function using
steps 1-2 in this section.

Press the button on the original alarm and the
RADIO light will stop flashing, or after one minute
the RADIO light will stop flashing automatically
and the network will close.

The slide switch will lock into place when fully
positioned.

Important Fire/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, CO
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.

Limited WarrantyWarning! Limitations of Smoke Alarms

Wireless smoke 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 smoke alarm is not a substitute for an
adequate homeowner’s fire insurance or life insurance policy.

Smoke alarms will not work without a source of power. The alarm will not
operate and the alarm will not sound if the batteries have died or been
deactivated. Or in the case of an AC powered alarm, the wiring has not been
properly connected.

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.

The alarm warning signal 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 fire drills are practiced that take this
possibility into account.

Current studies have shown smoke alarms may not awaken all sleeping
individuals, and that it is the responsibility of individuals in the household that
are capable of assisting others to provide assistance to those who may not be
awakened by the alarm sound, or to those who may be incapable of safely
evacuating the area unassisted.

Smoke alarms may not always activate and provide early enough warning. A
smoke alarm will only activate when it is maintained in working order and
sufficient smoke reaches the unit. Certain fires can originate inside of walls,
attics or on the other side of closed doors. This may prevent smoke from
reaching the alarm.

Smoke alarms may not be effective in certain situations, such as: Fires where the
victim is intimate with a flaming fire; for example, when a person’s clothes catch
fire while cooking; Fires where the smoke is prevented from reaching the alarm
due to a closed door or other obstruction; Incendiary fires where the fire grows
so rapidly that an occupant’s egress is blocked even with the properly located
alarms.

SMOKE ALARMS CAN NOT GUARANTEE THAT YOU WILL NEVER SUFFER ANY
DAMAGE OR INJURY FROM A FIRE.
