HOUSEHOLD GAS LEAKING DETECTOR The Household Gas Leaking Detector with SCM technology and the advanced low-current gas sensitivity components, enables detecting the gas leaked in time, then send out the alarm correctly. The Detector accords with the standard of "Household Gas Detector" of CJ3057-1996. GENERAL VIEW 2. Choosing the suitable position to install the Detector according to the gas heavier than air or not. Detecting the gas heavier than air: Installation height from floor: 0.3-1.0m.Semidiameter to gas source: <1.5m. Detecting the gas lighter than air: Installation height from ceiling: 0.3-1.0m Semi-diameter to gas source: <1.5m 3. Avoid installing the detector close to the following sources of interference: direct air flow form vents, fans, doors, windows, sources of steam, oil vapor, etc. 4. AC 220V and DC 12V optional. If you choose the AC 220V with the white cable, the detector will alarm by sound and light, and without the red/black/yellow/blue/green cables; Otherwise, the Detector without the white AC 220V cable if you choose the DC 12V power supply. DETECTOR CEILING 3. While detected the gas leaking, the red LED flashes, the Buzzer sends out the alarm sound "Di Di", and the network output signal. The Detector will resume for the detecting state after the gas taken off. 4. The buzzer long beeps and the green LED OFF means the inside sensor wrong. Please cut off the power supply, and contact the After Service Center. 5. While using the Detector independently, exhaust the leaking gas out of the window via using the N.O. contact of the network signal to control the exhaust-pipe. 6. If the Detector runs disorderly, cut the power off and rerun again. If still in error, please contact the After Service Center. TEST To test the installed Detector while using independently or in network, you can give some gas around in distance of 5cm to the gas convection windows by using un-ignition lighter. Gas AP GREEN ON: working state RED ON: Alarm indicator PR OX testing frequently may result in reducing the sensitivity of the IM E AT 2M Detector. The alarm density of gas is set according with the criteria of CJ3057-1996. The Detector will stop alarm and COAL OVEN resume the detecting state while the gas density reduced. The FLOOR alarm output switches can connect with the defense input switches of alarm system. NORMAL MAINTENANCE Suggestion: the user must brush and clean the gas convection windows with a little cleanser every three months, and must GAS CONVECTION WINDOWS retest the Detector after cleaning for preventing the cleanser 15-530 WIRES INSTALLATION DIRECTIONS TECHNICAL SPECIFICATIONS Induced Gas Coal Gas / Natural Gas AC 220V 50Hz Or DC 12V Power Input Buzzer Level 70dB/m Alarm Density 15% LEL Resuming Density 8% LEL Operating Humidity 90% RH Operating Temperature -10 Stableness 5% LEL Alarm Density Error Alarm Mode to 40 5% LEL Repetitiousness 5% LEL Flash & sound alarm/Network alarm signal 5W Power Consumption Size 120 x 120 x 51mm NOTE: Demarcating gas is Ch4 Terminal Block Figure All wires installation must accord with the National and Local effective laws and criteria.

Extinguish all fire sources and anything can make fire, e.g. USAGE The Household Gas Leaking Detector can be used independently, or with networks output functions. 1. Independently (1) Choosing the suitable position to install the Detector according to the INSTALLATION. (2) With DC 12V or AC 220V power supply, the green LED lighters, matches, etc. 4. Avoiding open/close all kinds of electricity. 5. Check the reason of gas leaking, and notice the relative departments and professional persons in time. LED INFORMATION RED LED FLASH gas leak running the inside sensor flashes once a second for 3 minutes continuously, that runs the GREEN LED FLASH inside sensor. Then the Detector sends out a sound "Di" and the GREEN LED ON working normally GREEN LED OFF power off or sensor destroyed green LED lights, that means the Detector entries normal the controller, with the N.C. or N.O. contact optional accord with the controller system. (2) With DC 12V or AC 220V power supply, the green LED INSTALLATION The Detector alarms while the gas density in air beyond the alarm density. The relative treatments as below: 1. Shut down the tube valve right away. And unsuitable connection of wires will result in the alarm error according to the INSTALLATION.

Choosing a suitable position to install the Detector, inside sensor. Then the Detector sends out a sound "Di" and the normally on the ceiling over the gas source, the best distance to green LED lights, that means the Detector entries normal the gas source is approximate 2m. working state. NOTICE 1. The detector must be installed and connected accordingly. It can not work if without the power supply orderly. 2. Please periodically maintenance according to the directions. 3. The Detector must have a test every half a year. 4. For various reasons, including, but not limited to, changes in environmental conditions, electric or electronic disruptions and tampering, the Product may not perform as expected. The user is advised to take all necessary precautions for his/her safety and the protection of his/her property.
