Frequently Asked Questions - 34151 CHACON

What to do in case of an alarm?

In case of an alarm, immediately open windows and shut off the gas valve. Do not turn on any electrical devices. If the alarm persists, leave the premises and call emergency services. The detector automatically disarms when the concentration returns to normal.

How to test the detector?

Press the center button once: the detector simulates an alarm with flashing red LED and audible beep, then returns to normal state. Perform this test monthly.

Where to install the gas detector?

Install it near your stove, water heater or any gas source, 1 to 4 meters from the appliance and at most 30 cm from the ceiling, because methane and natural gas are lighter than air.

What does the solid yellow light mean?

The solid yellow light accompanied by a continuous beep indicates a detector failure. Contact the distributor for repair.

What is the lifespan of the sensor?

The semiconductor sensor has a lifespan of 5 years under normal operation. When it reaches end of life, the lifespan indicator flashes 3 times with 3 beeps.

How to clean the detector?

Use a brush or soft dry cloth to remove dust or oil residues from the surface. Clean at least once a month.

Why does the alarm continue after warm-up?

This may be due to cigarette smoke, alcohol, or volatile organic compounds (gasoline, perfume, paint). Ventilate the room and try again. If the problem persists, contact the distributor.

What to do if the green light does not turn on?

Check that the power cable is properly connected. If the light remains off, the circuit may be defective: contact the distributor.

Can this detector detect carbon monoxide?

No, this detector is designed only for methane (CH4), biogas, and natural gas. It does not detect carbon monoxide, carbon dioxide, or smoke.

What to do at the end of product life?

When the lifespan indicator flashes 3 times with 3 beeps, the sensor is at end of life. If the warranty is valid, contact the distributor, otherwise replace the device.

0. Introduction

Thank you for using this product.

• Please read all instructions carefully before using the product.
• Do not attempt to disassemble or repair the product yourself, otherwise the product will be out of warranty.
• This alarm has been designed and tested to detect gas leaks in a residential environment. It implements the EN 50194-1:2009 standard.
• This gas leak detector is designed to detect methane (CH4), biogas and natural gas. It cannot be used to detect smoke, carbon monoxide or carbon dioxide.

1.1. Product Installation

This detector is suitable for indoor use only. This device is recommended near your cooker, water heater, and near any gas-fired source. It should be installed 1m\~4m from the gas appliance and maximum 30 centimetres from the ceiling.

Tip: It is advisable to check that the device is working properly before installing the detector on its mounting plate. Make sure that the location is close to a power source (socket).

2. Indication of product operation

2.1. Connecting the device to the power source

When you plug in the detector, the status indicator LED flashes green. Then it automatically goes into warm-up mode for 3 minutes. During this time, the unit cannot detect gas leaks. After 3 minutes, the green LED will light up to let you know that it is operational and ready for use.

2.2. The status indicator turns red

When the gas concentration value in the air reaches the set alarm point, the detector enters the alarm mode. An audible alarm of 85dB will sound and the status indicator will flash red. Open the windows immediately and turn off the gas valve. Do not turn on or plug in any electrical appliances. If the alarm does not stop, please leave your home, and call for help. If necessary, ask your electrical and gas inspection expert to come and check your installation.

Note: In the alarm state, when the gas concentration is below the safe value, the detector automatically disarms the alarm.

2.3. Failure warning

If the LED on the status indicator is yellow and lights up continuously and beeps, it means that the detector is defective and cannot detect properly, please contact the distributor for repair.

Tip: We advise you to check the device daily. To do so, please press the central button once, the detector will enter the alarm simulation mode and will emit an audible and luminous alarm signal, the red LED will flash and beep, then it will return to the normal detection state.

2.4. End of life warning

If the lifetime indicator flashes 3 times continuously and at the same time beeps 3 times, the lifetime of the sensor has expired. Please contact your dealer if your warranty is still valid or get a new sensor.

2.5. Device status summary

3. Advice - installation locations

We recommend that you install the gas leak detector near your cooker, water heater and near all gas sources. Methane (or town gas), biogas or natural gas is lighter than air and therefore rises, so place your device of about 30 cm from the ceiling.

To avoid damage to the product and to prevent false alarms, do not install the unit in the following locations:

• Air inlet/outlet areas, exhaust fans, doors/windows with strong air circulation.
- Areas with moisture and water drops, e.g. in your bathroom.
- Areas directly above a source of heat or steam.

Note: If the room must be painted or renovated, please install the detector after the renovation or painting work.

4. Troubleshooting

Note: For any faults that cannot be resolved by yourself, do not dismantle the detector, please contact the distributor for advice.

Faulty Possible reason(s) Action(s)	to be taken
The green light of the power source is not on	Power source cable not connected properly	Check and connect the cable to the power source correctly
	Power source indicator damaged or circuit failure	Contact the distributor for repair

No audible and visual alarm during self-test	Circuit failure Contact the distributor for repair
No response to detected gas Still preheating Wait for the warm-up to finish

5. Maintenance advice

The product must be kept clean when in use, otherwise its performance will be affected and may even damage the alarm. It should be cleaned and tested at least once a month.

• Please clean dust or oil contamination on the surface of the detector regularly with a soft, dry brush or cloth. After cleaning, reinstall the detector on its base plate and perform a function check.
  • After long storage or transportation, please turn on the detector and wait 24 hours or more for optimum performance.
• This product cannot be used or stored in an environment containing corrosive gases (such as chlorine)
• The presence of large amounts of cigarette smoke, alcohol, or volatile organic compounds such as petrol, perfume or paints in the room may trigger the detector's alarm.
• The detector must be connected to a stable power source.

Note: In a normal operating environment, the solid-state sensor can operate for 5 years.

6. Preventive actions for heating, hot water and in the kitchen

• Have your flues and chimneys swept once a year, which is the minimum requirement, or twice for extra precaution.
• Have your installation checked regularly, for example as part of a maintenance contract. It is also compulsory to have your boiler serviced every year.
• Clean the ventilation grilles regularly and never place a piece of furniture, a towel, or any other object in front of a ventilation opening so as not to obstruct the escape of gases.
• Ventilate your home regularly.
• Turn off the natural gas tap every time you leave for the weekend or on holiday.
• Clean the burners of your gas cooker regularly: a blue flame is a guarantee of safety.
• If your cooker is connected via a flexible tube, replace it with a flexible tube with mechanical screwed ends, which is very difficult to tear off; if you already have a flexible tube, check its

validity date.

CAUTION: If you detect a leak, ventilate immediately, turn off the natural gas supply and avoid actions that could cause a spark (e.g. touching switches or circuit breakers, turning on the light, making a phone call from a landline or mobile phone, etc.)

If the leak is ignited, there is no longer any risk of explosion: if possible, close the appliance's supply valve or the natural gas supply, wet the nearby surfaces, evacuate the building, and call for help.
