PRODUCT INTRODUCTION

This p roduct is a comb ination unit o f smoke and ca rbon

monoxi de d etector. The smoke chamber usi ng the pri nciple of

smoke parti cles reflectin g inf rared lights can accur ately detect

the ea rly smo ke of a f ire. And t he gas detection adopts a carbon

monoxi de electr ochemic al sensor to ensur e stable and const ant

pe rfo rmance. When c onc entrati on o f the leak ed carb on

monoxi de or sm oke den sity re aches the gi ven alarm level, the

detect or LED flashes red and buzzer gives out alarm sounds.

Beside s suitab le for earl y warning and protect ion of carb on

monoxid e leakages o r fires in hou ses , villas , factories ,

shoppi ng mall s, ware houses, office buildin gs etc. indoo r

places , this unit h as a subtle s hockproof d esign, wh ich makes i t

also sui table for v ehicle use.

2. Fix the detector ba se in to a wal l or ceili ng wit h scre ws and

fasten t he detect or head on the ba se.

3. While insta lling at home, keep t he d etector awa y from your

gas stove to preve nt flame roasting. Avoid instal ling in

places wi th heavy oil or smoke th at may c ause false alarm o r

block the gas convect ion hole s and inf luence the detec tor

sensit ivity. Also do not ins tall t he det ector near to exhau st

fans, window s, doo rs and in places with great vap or in

bathro oms.

OPERATING PRINCIPLE

1. Inser t 2p cs 1 .5V AA batteri es into the batte ry c ompartmen t.

The dete ctor enters into warm- up status. LE D flashes G reen.

2. About 3 mi nutes later, the flas hing Green LED goes out. And

the det ector goes int o norma l wor king status. The LED

flashe s Gree n once every 30s, indicati ng nor mal ba ttery

supply.

3. The det ector shou ld be teste d period ically dur ing use. Short

press Tes t & Hush Butt on to ru n a test. The LED flashes Red

along with buzze r sou nding for alarm indicat ion. Smoke

flashi ng red at th e sam e frequ ency, last ing for abo ut 8s.

Then comes the carbo n mo noxide alarm indica tion: short

same freq uency, lasting also for abou t 8s. Do not tes t the

detect or too oft en to save battery life. One a month is

recomm ended.

4. Duri ng alarm ing status , short press the Test & Hush Bu tton.

Then the detector g oes into mu te status . Th e LED keeps

flashi ng red while t he buzzer w ill stop sounding. If the

alarm sta tus hasn’t been re set, the mute sta tus will end

automa tically in 10 minutes later. The buzzer sounds aga in.

If the alarm status is rese t during the 10 minutes , the

detect or recove rs to normal wo rking statu s.

5. T he detector can auto check open circuit, sho rt ci rcuit and

other m alfunctio ns in smoke chamber. D uring malf unction,

the LED flas hes y ellow, t wice a minute along with buzzer

soundi ng to warn us er.

6. Wh en bat tery voltage < 2 .4V, the detector will give out low

batter y signal peri odically. The LED flash es yellow, once

every 30s al ong with buzzer sou nding. While the batter y

voltag e < 2.0 V, the LED constant yellow and the detector

will res tart in 32s d ue to low power. Afte r warm-up a nd

EMERGENCY ALARM TREATMENTS

Tre atments for c arbon monox ide leaka ge alarm:

1. Shut off tu be valves.

2. Do not pl ug or unplu g electrica l appliance s.

3. Open wi ndows to ci rculate the a ir.

4. Inspect the l eakage r eason and notify re lated de partments or

profes sionals in time to deal with the situa tion. If it t urns out

a false al arm, check if the instal ling positi on is impro per.

Tre atments for s moke alarm:

1. Inspect the cau ses. If i t is caused by cigare tte smo king or

other rea sons and not a fir e alarm, just remo ve the smoke

resour ce and th e alarm w ill reset. If it is a false al arm, che ck

if the ins talling p osition is im proper.

to put out t he fire.

3. If the f ire is large, do n’t p anic. Esca pe asap and th en call the

police .

NOTES

1. Replace the bat teries with new ones in time on low battery

condit ion to ensu re normal ope ration.

2. No bloc k within a ra dius of 0.5m fr om the detect or.

3. T he hori z ont a l di stan ce from t he detec tor t o th e ai r

condit ioner out let should no t be less than 1. 5m.

4. I f nee ds to instal l the detect or in an a isle ce iling with a width

less than 3m, choos e a cen ter posi tion. Ke ep the distance

betwee n the detectors less th an 15 m. The distance from the

detect or to t he end wa ll shou ld not ex ceed half of the

distan ce betwee n the detecto rs.

5. Clean the det ector surface with soft brus h every month to

ensure sensi tivity. Do not spray air-f reshers , hair gels,

paints o r other aer osols near th e detector.

6 . Th e l i fe s pa n o f t h e a do p te d c a rb o n mo n o xi d e
