TWO WAY WIRELESS

SMOKE DETECTOR

INSTALLATION INSTRUCTIONS

P/N 7102316 REV. B (D.Z.)

INTRODUCTION

The FW2-Smoke detector is an advanced, fully

supervised low-current wireless detector that

includes a FW2 transceiver for reliable system

operation.

The FW2-Smoke detector includes special

chamber structure for best smoke detection

performances.

The FW2-Smoke detector uses smart message

control, which verifies that all messages are

successfully transmitted, so that no smoke or any

other event will be uninformed to the base.

The FW2-Smoke detector includes series of

messages for full communication administration

(Supervision, Tamper Status, Battery Status, Alert,

etc.) as well as test transmission signals.

FEATURES

Freewave FW2 ISM protocol.

Low current Technology.

Powered by 3V Lithium battery pack.

Battery life: >10 years.

Audible Warning by a built-in horn (three beeps)

in Test mode or Alarm.

Frequency Band: 868.35MHz or 916.5MHz.

Tamper Open/Close transmission.

Supervision transmission.

Battery status transmission.

Bi-Color LED indications.

Range up to 500m on open space.

OPERATION

This FW2-Smoke detector transmits the

following events data:

SUPERVISION –A periodical transmission

(configurable) indicating detector’s presence.

ALARM –Alarm transmission triggered by the

device indicating Smoke detection. The Red LED

will blink once.

LOW BAT –Whenever the battery reaches the

low level (2.5V), a Battery Low signal will be sent.

When Battery level drops below Cut Off level

(2.3V) the device will stop functioning and the Red

LED will blik for 10 seconds and then turned Off.

TAMPER –Whenever the cover is removed from

Bracket or the device is tear off from the celling, a

message will be transmitted with “Tamper ON”

signal. When the device will be returned to its

place a “Tamper OFF” signal will be transmitted.

INSTALLATION LOCATIONS

Smoke detectors shall be installed in accordance

with NFPA Standard 74. Here are few useful tips

for complete coverage in residential units:

Install a smoke detector in the hallway outside

every separate bedroom area. Two detectors

are required in homes with two bedroom areas.

Install a smoke detector on every floor of multi-

floor home or apartment.

Install a minimum of two detectors in any

household.

Install a smoke detector inside every bedroom.

Install smoke detectors at both ends of bedroom

hallway if hallway is more than 12m (40ft) long.

Install a smoke detector inside every room where

one sleeps with the door partly or completely

closed, since smoke could be blocked by the

closed door and a hallway alarm may not wake

up the sleeper if the door is closed.

Install basement detectors at the bottom of the

basement stairwell.

INSTALLATION LOCATIONS (Continue)

Install second-floor detectors at the top of the

first-to-second floor stairwell.

Be sure no door or other obstruction blocks the

path of smoke to the detector.

Install additional detectors in your living room,

dining, family, attic, utility and storage rooms.

Install smoke detectors as close to the center of

the ceiling as possible. If this is not practical, put

the detector on the ceiling, at least 10 cm (4 inch)

away from any wall or corner.

If ceiling mounting is not possible and wall

mounting is permitted by your local and state

codes, the wall-mounted detectors shall be

installed between 10cm to 15cm (4 - 6 inches)

from the ceiling.

If some of your rooms have sloped, peaked, or

gabled ceilings, try to mount detectors 0.9 m

(3feet) measured horizontally from the highest

point of the ceiling.

WRONG INSTALLATION LOCATIONS

False alarms occur when smoke detectors are

installed where they will not work properly. To

avoid false alarms, do not install smoke detectors

in the following situations:

Combustion particles are by-products of

something burning. Do not install smoke

detectors in or near areas where combustion

particles are present, such as kitchens with poor

ventilation, garages where there may be vehicle

exhaust, near furnaces, hot water heaters and

space heaters.

Do not install smoke detectors less than 6 m (20

feet) away from places where combustion

particles are normally present. If a 6 m (20 feet)

distance is not possible try to install the detector

as far away from the combustion particles as

possible, preferably on the wall. To prevent false

alarms, provide good ventilation in such places.

WRONG INSTALLATION LOCATIONS

The path of fresh air intake. The flow of fresh

air in and out can drive smoke away from the

smoke detector; thus reducing its efficiency.

In damp or very humid areas or near

bathrooms with showers. Moisture in humid air

can enter the sensing chamber, then turns into

droplets upon cooling, which can cause

nuisance alarms. Install smoke detectors at

least 3 m (10 feet) away from bathrooms.

In very cold or very hot areas, including

unheated buildings or outdoor rooms. If the

temperature goes above or below the operating

range of smoke detector, it will not work

properly.

In very dusty or dirty areas, dirt and dust can

build up on the detector’s sensing chamber, to

make it overly sensitive. Additionally, dust or dirt

can block openings to the sensing chamber

and keep the detector from sensing smoke.

WRONG INSTALLATION LOCATIONS

Near fresh air vents or very drafty areas like air

conditioners, heaters or fans. Fresh air vents

and drafts can drive smoke away from smoke

detectors.

In “Dead Air” spaces like at the top of a peaked

roof, or in the corners between ceilings and

walls. Dead air may prevent smoke from

reaching a detector.

In insect-infested areas. If insects enter a

detector’s sensing chamber, they may cause a

nuisance alarm. Where bugs are a problem, get

rid of them before installing the detector.

Near fluorescent lights, electrical "noise" from

fluorescent lights may cause nuisance alarms.

Install smoke detectors at least 1.5 m (5 feet)

from such lights.

PAIRING PROCESS

1. Separate the Smoke from its bracket by

rotating the device counterclock wise.

2. If not done so before, shortly press the Pairing

button to power up the device. This activity

shall be done only once during the product life

time.

3. Wait until the Red LEDs stops blinking.

4. Refer to your control panel manual for learning

mode procedure.

5. When registration process is successfully

completed the Green LEDs will

constantly light On for 3 seconds and

then turn Off.

6. If registration process failed the Red

LEDs will blink. wait for few seconds

(~10sec) and repeate the pairing process

from step 4 above.

TESTING THE DEVICE

ALARM TEST

Press shortly the "Test" button (See Figure 4) -

the smoke detector shall respond with "Bip-Bip-

Bip" sound, indicating that the device is in the

normal mode. If the test fails, stop using the

detector immediately.

WARNING

DON’T TEST IT WITH FIRE !!!

TAMPER TRANSMISSION TEST

Attaching / Removing the device to / from its

bracket will cause tamper transmissions. Verify

receiving the indication on your Application / Base.

IDENTIFICATION TRANSMISSION TEST

Use your Application / Base to send

Identification Request to the Smoke. The

Smoke will blinking the Green & Red LEDs

alternately –5 times.

FIGURE 1 –PAIRING BUTTON

MOUNTING THE DETECTOR

1. Hold the mounting bracket against the ceiling

and mark the center of each slot. Drill 2 holes

and install the barcket with the screws –Fig 2

2. Verify the Smoke detector is learned into the

control panel by pressing the Tamper button

(see below Figure) and verify receiving suitable

message in the Base.

3. Push the Smoke detector toward the bracket

and turn it clockwise to adjust the detector to

the bracket –see Figure 3.

FIGURE 4 –THE TEST BUTTON

REGULAR MAINTENANCE –CLEANING

Never use water, cleaners or solvents to clean

your smoke alarm since they may damage the

unit. Use a soft brush only.

Remove the Smoke detector from its bracket and

carefully remove any dust from the Smoke’s

openings around the device (see below Figure) at

least once a year.

LIMITATIONS OF SMOKE ALARMS

1. United States NFPA72 tells that the safety of

life is to be noticed by alarms before fire, to

confirm the correct escape way. The fire

systems help half of residents escape. Help to

old people, women and children shall be given

since they are always the victims.

2. Smoke alarms are not foolproof, they can’t

prevent or extinguish fires, and they are not a

substitute for property or life insurance. You

need buy some firefighting facilities.

3. Sometimes the smoke is blocked by objects

and can’t reach the detector, and if the wind

blows the smoke away from the detector, the

unit won’t work either.
