PRODUCT PROFILE
INSTALLATION
1. Please c onfirm the induc ed gas is heavier t han air, or lighter
than air. The gas is heavier than air: LPG etc. The gas is
lig hter than air: na tural gas, marsh gas and etc.
2. Ch oosing the s uitable po sitio n to install t he De tector
according to th e gas specific gravity. Detecting the gas
heavi er t han air: Installation height from floor: 0.3-
1.0m,Semi-dia meter to gas source: <1 .5m;Detecting the gas
light er than air: Installati on height from ceiling: 0.3-1.0m
,Semi-diameter to ga s source: <1.5m.
3. Fi x the screw into the wal l firmly, then h ang the detector.
4. Avoid instal ling t he detector close to the followi ng sou rces
of interference: dire ct air fl ow from v ents, fans, do ors,
windows, sources of steam, oil v apor, etc.
5. All wires installation mus t accord with the Natio nal and
Loc al effective laws and criteria. The wires must have the
suitable size and col orful ma rks for av oiding connec tin g
error. A nd unsuitable connection of wire s will r esult in the
alarm er ror whi le gas leaking happe ned.

The Ga s Detecto r ca n be used inde pendentl y, or w ith
wired network s output functions.
1. Independen tly
(1) Choos ing a suitable posi tion to install th e Detector
according to th e INSTALLATION.
(2) With DC 12V or AC 22 0V power supply, the green LED
flash es once a seco nd for about 3 min utes cont inuously,
that runs the inside sensor (warm-up state). After doing
that th e green LED lights , that means the Detector co mes
into norma l wor king state.
2.In wired network
(1) Choos ing a suitable posi tion to install th e Detector
according to t he I NS TALLATI ON . To con ne ct t he
Det ector with the contro lle r, with the N. C. or N.O. con tact
optional accord with the controller syst em.
(2) With DC 12V or AC 22 0V power supply, the green LED
flashes once a sec ond for about 3 minutes cont inuously,
that runs the in side sensor (warm-up state). Aft er doing
that the green LED lig hts, that mea ns the Detector comes
into norma l working state.
3. While de tecti ng the gas leaking , the red LED flas hes, t he
Buz zer s ends out the ala rm so und "Di Di", an d output
the n etw ork signal . If the detector is connected wit h valve
or ma nipulato r, it will drive them to shut o ff the gas pipeli ne
supply. The Detector will r esume t o the detecting state after
the gas di spersed.
4. Fo r model series without dri vi ng manipula tor ,it will enter
the test status whe n press t he te st butt on and exit when
loosen. Fo r model series driving manipu lator, it wil l enter
the test statu s after pressing the test butto n for mor e than 4
seconds. if less than 4 seco nds, it is switch on /off t he
man ipulator functi on.
5. Th e buzze r long beeps a nd the ye llow LED ON means the
inside sensor failure. Please c ut off the power, and conta ct
the After- sa les S erv ice Center.

TEST
Su gg es ti on : the user must b ru sh and clean t he gas
convection h oles wi th a lit tle clean ser every t hree months, and
must retes t the Dete ctor af ter cleaning f or prevent ing the
cleanser i nto the Detector.
NORMAL MAINTENANCE
The Detector alarms while the g as dens ity in a ir e xceed the
alarm level. The relative trea tments as below:
1. Sh ut down the tube valve righ t away.
2. Op en the window and ma ke the air flo w rapidly.
3. Ex tinguish all fire source s and do not use anything can make
fire, e.g. lighters, matches, etc.
4. Avoiding open or close the power all kinds of electric
Equipment.
5. Check the reason of gas leak ing, and notice th e relative
departme nts and pr ofessional persons in time.
EMERGENCY ALARM TREATMENT
NOTICE
1. The detector mu st be in sta lled and conn ected correctly. It
can not wo rk if without the power supply ord erly.
2. P leas e p e rio d ica l ly mai nten a nce a c cor d ing t o t he
direc tions.
3. The det ector mu st have a test every half a year.
4. Fo r var ious reaso ns, includ ing, but not li mited to, chang es
in e n vir onme nta l c ond i tio ns, e l ect ric o r ele ctro nic
disru ptions and tamper ing, the Product may not per form as
expected. The user is a dv is ed to t ak e all n ec essary
preca utions for his/her safe ty and the p rotection of his/her
property.
To te st the inst all ed detec tor while usin g independe ntly or
in netwo rk, you can give some gas aro und in distan ce of 5cm
t o t h e g as c on ve ct i o n h ol e s b y u si n g un-ign i t i o n
lig hte r. Test ing freq uently may r esu lt in r edu c in g t he
sensitivity of the Detector. The alarm den sity of gas is set
accor din g with th e crite ria of GB15322.2-2003. The Detector
will stop alarm and res ume to t he detecting state while the gas
densi ty reduc ed to l owe r than the al arm l evel. The alarm
output swi tches can connect with the defense input switche s of
alarm system.
