• Audible and visual alarm

AN ACCURATE GAS SENSOR WITH LOW POWER CONSUMPTION AND HIGH SENSITIVITY.

This unit is applicable anywhere combustible gasses are used. Once the level of combustible gas reaches the preset alarm level, an alarm will sound and the user will see an LED indication. The detector has visual and audible indications for fault, low battery and alarm.

2. FEATURES:

Auto zero calibration Fast response and resume Easy to operate A variety of sounds for different status Large range of operating temperature

3. SPECIFICATIONS:

Gas detected: natural gas (methane), LPG (propane, butane) etc. and other combustible gases.

Range: 0~100%LEL Sampling: Natural diffusion Operating temperature: -4° to 131ºF (-20° to 55ºC) Operating humidity: < 95%RH

5. OPERATING INSTRUCTION:

1. Open the battery cover and insert two “AA” batteries into the unit. Observe polarity.

2. SWITCH ON; the detector will start its 15 second warm up. The three LEDs will light in turn. After a tweet, the red and yellow LED will be off. The warm up will be finished. The detector is ready to detect gas.

3. Visual and audible indication instruction: The green power LED will flash consistently during operation. There will be a sound alarm every 7 seconds during the non

alarm status.

LOW ALARM: when the gas concentration is between the low alarm and high alarm point, the detector will give a sound alarm every 0.5 second and the yellow LED will light.

HIGH ALARM: when the gas concentration is above the high alarm point, the detector will give a sound alarm every

0.5 second, the red LED and the yellow LED will light. LOW VOLTAGE: when the battery power is lower than 2.7V, the

detector will give a sound alarm every 30 seconds. SENSOR FAULT: when the sensor faults, the detector will give a

sound alarm every 1.5 seconds and the yellow LED will light.

6. NOTICES:

• The alarm may be activated if there is smoke, alcohol, perfume or

other volatile items in the vacinity.

• Please activate the product in clean air. If the detector is

activated in a gas concentration above 30%LEL, the detector may indicate sensor fault. Then you need to reactivate the detector in clean air.

• Avoid excess shock. Do not place any pressure on the tip.

• Low voltage may affect the sensitivity. Please replace the

batteries as soon as possible when the power is low.

• Don’t store the detector in the environment with caustic gas.

• Please operate according to the operation manual.
