Gas Detector

www.techly.com

The product is an indoor combustible gas detector with

high stability, used for combustion gas leak detection. It

uses highly stable semiconductor gas sensor with fea-

tures of stable performance and low drift of sensitivity.

When it senses combustion gas leak that reaches the

alarm level, it will gives out alarm sound with red LED

ﬂashing. The detector is applied in indoor areas where

combustion gas leaks may happen.

Technical specication

Installation

1. First please conrm if your gas is heavier than air, or

lighterthan air. Heavier gases: LPG etc; Lighter gases: na-

tural gas, marsh gas etc.

2. Choose a suitable position to install the detector ac-

cording to the gas specic gravity. For detecting heavier

gases, installation height: 0.3 - 1.0m from ﬂoor, within

the radius of 1.5m from gas source. For detecting lighter

gases, installation height: 0.3-1.0m from ceiling, within

the radius of 1.5m from gas source (refer to the following

image).

3. Fix the attached installing base into a Wall rmly with

screws and hang the detector.

4. When installing at home, keep the detector away

from gas cookers to avoid being roasted by ﬂame. Do

not install the detector in places with heavy smoke and

oil which may cause false alarms or block the gas con-

vection holes of the detector, which aects the detector

sensing sensitivity. Also do not install it near to exhaust

fans, windows, doors, and places with heavy vapor in

bathroom.

5. Correctly connect the wires. All wiring and installation

must accord with the National and Local eective laws

and criteria. Improper connection will cause the detector

not alarm on gas leaking.

Installation guide layout

Operating instruction

1. The detector will work just simply by plug-in.

2. After plug-in, the power LED constant on green. With a

“Di” sound from buzzer, the detector enters into warming up

state.

Red and yellow LEDs ﬂash alternatively. 3 minutes later, the-

LEDs go out and the detector goes into normal working state.

Testing with gas is forbidden during warming up.

3. When a combustible gas leak happened and reached the

given alarm level, the alarm LED will ﬂash red and the buzzer

will give out “Di...Di...“ alarm sounds. Meanwhile, the detec-

tor will send out wireless alarm signal.

4. The detector checks sensor failure automatically during

working. For sensor failure, the Fault LED on yellow

constantly along with buzzer sounding. For this situation,

unplug the detector and contact your vendor. Do not take

apart the detector or try to repair it by yourself.

Switch to Connection Mode on the control panel. Press

the test button of the sensor twice. The control panel be-

eps once: the gas detector is registered. If you hear two

beeps,the detector has already been connected. To check

if the registration is complete, arm the system and trigger

the sensor again. If the siren rings out, the registration is

successful.

Testing

1. The detector has a self-test button for checking if the LEDs

and the buzzer work normally. Pressing the test button, the

red and yellow LEDs ﬂash alternatively and the buzzer gives

out alarm sound and meanwhile the detector will sent out

Wireless alarm signal.

2. It is forbidden to test with a lighter directly towards the

gas convection holes. This may cause damage to the inside

sensor. Instead, gather the gas from a lighter into an empty

plastic bottle and point the bottle mouth towards the gas

convection holes to release the gathered gas for testing.

Failure analysis & treatments

Emergency alarm treatment

When the natural gas level in air around the detector rea-

ches or exceeds the given alarm level, the detector will

automatically enters into alarm state. Below treatments

are advised:

Close the gas tube valve right away.

Do not plug or unplug electrical appliances.

Open Windows to circulate air.

Inspect the gas leak reason and notify the related

department or professionals to inspect and handle the

leakage. If it turns out to be a false alarm, check if the

installing position is

improper.

Warning!

1. The product is a combustible gas detector. Can not be

used to detect toxic gases such as carbon monoxide.

2. Make sure proper wiring and power supply are applied.

Without normal power supply, the detector will fail to

work.

3. At working time, mild heat-up in housing surface is

normal.

4. Maintain the detector periodically as required in this

manual.

5. Use cleaner to vacuum the dust in surface every month.

6. Do not use any detergents or solvents to clean the

detector. Chemicals may cause permanent damage or

transient pollution to the sensor.

7. Avoid spraying air fresheners, hair gels, paints or other

aerosols near the detector.

8. Test the detector by a professional every year to as-

sure the detector sensitivity. If the detector fails to work

properly, repair or replace it asap.

9. The service life ofthe detector semiconductor gas sen-

sor is 5 years. Replace the detector immediately when

the service life expires.

10. The detector can reduce accidents happening, but can

not guarantee a hundred percent safety. For your securi-

ty, besides proper usage of the detector, pay attention to

build up safety conscious and take preventive measures

in daily life.
