Flammable Gas Alarm Installation and Inspection
Flammable gas alarm is used at home, hotel, restaurant and chemistry industry, factory etc. It consists of detector and gas density indicator. It monitors the leakage of flammable gas and show density of flammable gas. When the flammable gas detector is installed, the monitored field is fixed. There are a few key notes to refer before installing. 1.Make sure the points of potential gas leakage and calculate leakage gas pressure, leakage volume at unit time and leakage direction. Mark A, B, C as leakage degree. 2.According to air flow at the spot, draw direction of leakage. 3. According to leakage gas density (heavier than air or lighter than air), and air flow trend, draw the 3D leakage flow drawing. 4. Set monitor point under the flow point made at leakage flow drawing. 5. We need to guess the leakage state whether it is slight leakage or spraying leakage. If it is slight leakage, we need to install the detector near it. Otherwise, we can install the detector a little far away. 6. It is suggested to have detector every 10-20m. 7. For spot with hydrogen leakage, we need to install detector over the leakage point. Regular inspection is required for the flammable gas alarm device.

Terms meaning of alarm panel setting
When you start DIY Your home security, there are some terms of the alarm systems you should know. The home security system is designed smarter and intelligent. But at the same time, it showed too sophistical for home owners, end-users to DIY. 1. What is entry time & leaving time? Entry time: It is alarm delay time. Arm the system, and when it is triggered, it will send information out after the entry time set. That would enable people to disarm when miss trigger occurred. Leaving time: It is arm delay time. Arm the systems, and it will start to arm after leaving time set. That will enable people to leave home after house is armed. 2. What is at home arm/disarm and away home arm/disarm At home arm/disarm: You can set some defense zones into one group, and use remote controller to arm/disarm with one click to set all. For example, you can set 1st floor, outdoor detectors armed but 2nd floor disarmed when you are at home. Away home arm/disarm: You can set some defense zones into one group and use remote controller to arm/disarm with one click to set all. For example, you can set all floors armed when you are away home. 3. What is defense zones attribution? The zones attribution include: 1. zone disabled. The control panel will not accept any information from this zone. 2. Burglar zones. The zones will be arm/disarmed etc. controlled via master control panel. Alert information will be burglar alarm. 3. Medical help: The zones will not be arm/disarmed controlled via panel but 24 hours armed. Alarm information sent will be medical help alert. 4. Fire alarm zone: The zones will not be arm/disarm controlled via panel but 24 hours armed. Information sent will be fire alarm. 5. Emergency zones: The zones will not be arm/disarm controlled via alarm panel but 24 hours armed. Information sent will be emergency alarm. 6. Gas leakage zones: The zones will not be arm/disarm controlled via panel but 24 hours armed. Alert information sent will be gas leakage alarm. 7. Door bell zones: The zones will not be arm/disarmed controlled via panel. But only door bell sound will be sent on-site. It will not dial out. 4. Telephone attribution: Telephone attribution include: 1. Telephone disabled. The system will not dial this telephone when alarm. 2. Voice format: Voice information will be sent when alarm. 3. CID format: CID information will be sent when alarm. 4. Arm Center: Only dial when system is armed. 5. Disarm Center: Only dial when system is disarmed. 6. Low power: Only dial when panel is with low power or AC power off. 5. Setting dialing times: It is to set the maximum times of dialing when alarm information is not dealt with. If the user answered the call and disarmed the system, it will not dial any other telephones. If the user answered the call and did not disarm the system but other operation, it will not dial this telephone but dial other telephones. 6. Setting ringing times of remote controlling: You can set the ringing times to accept remote controlling such as arm/disarm, listening etc. via telephone or mobile. 7. Breaking into alert function: Breaking into alert means when telephone line is occupied by telephone extension, the system will break into dial alarm and recover then. 8.

Advanced technique of intruder detectors
Intruder detectors decide the reliability of the alarm systems. To avoid the interference, anti-detection of fault alarm and missing alarm, multiple techniques are used in detector designing. 1. Micro-wave sending time will be staggered when more one detector is operated synchronously. So, maximum 4 pcs MW & PIR detectors can be installed in one room. 2. PET immunity: The infrared signal detected will be stored and compared with human body signal and excluded pet movement alarm. 3. Two infrared sensors are used to detect motion. The signal detected will be stored in RAM and will be calculated by logical addition, then the result and original signal will be compared to judge whether or not it is true alarm. 4. Anti-detection design: When the detector is set at anti-detection mode, CPU will analyze the weak signal detected and if it found it is anti-detection, It will active the micro-wave sensor to detect, and logical calculate both signals to judge. 5. Auto temperature compensation design to avoid environment temperature change. 6. Two infrared sensors are built-in. Motion sensors detected are same polarity and RF, electric magnetism, static electricity interference are opposite polarity. So, it can anti interference. 7.Micro consumption current designed for long life battery usage. From www.vedardalarm.com/forum

Notice for wiring FC-7448 bus-line alarm system
FC-7448 bus-line alarm system is meian tech FOCUS brand large business security, community security, commercial security system. It adopts new technology PC and security communication method. It is popularly used by security service. There are many optional accessories for system expansion. They are telephone line monitor module, RS232 interface module and micro- printer, monitored circuit input module, bus-type detectors. Below is the notice and guide to help wiring FC-7448 bus-line alarm system. It is best to wire all modules and detectors to alarm control panel with one bus-line cable. If it is not available, then it is best to have branch line longer than 300m. The wiring cable should keep distance from strong interference cables such as 220V AC power cable and fluorescent lamp etc. and avoid to wire in parallel with them. If the wiring cable length is more than 1.5km,then FC-7425 bus-line separator is needed. One FC-7425 can extend as long as 1.5km (RVV2*1.5mm cable is used). If more than one FC-7425 is used, then the extended distance depends on the cable used and the performance environment. Power supply: Generally centralized power supply is used, that is all devices or some nearest devices share a power supply. All devices should have enough working power supply, if not, then additional power supply device is needed. When multiple power supply devices are working together, then connect the ground of all the power supplies together and connect to the black end of alarm panel. Each power supply device positive terminal connects to its supplied devices. Connect all the wires’shield together and connect to power ground with one end only(no multiple ground). Connect all modules to bus-line. The module address DIP switch is binary, and any two module addresses can not be the same. Connect detectors to modules. After complete all wiring works, check the wiring of all the devices in turn to see if there is missed and misplaced wiring. Use multiple-meter to check whether or not there is short-circuit between all wiring. Ensure all wiring are correct and turn on the power. If there are multiple power supplies, remember to turn on alarm panel power supply at last.

How to install and debug FC-7448 Commercial Security Alarm System
Steps for wiring FC-7448 bus-line alarm system Step one: Purchase cables and power supply devices Purchase correct cables. 2-wire bus-line cable: cable diameter should be 0.8-1.0mm² (if wiring distance less than 500m, then 0.5mm²is OK). Cable type is RVVP, for example 2*0.8mm² Power supply cables 2-wire 12-24V cable with diameter 0.8-1.0mm² Purchase correct power supply devices 12-24V DC power supply device. The main power consumption device is detectors,especially photoelectric beams detector. Alarm panel power consumption is 50mA at standby status and 500mA at alarm status. Module power consumption is 20mA. Add all devices consumption current and multiplied by 2 to get power supply device power requirement. Multiple power supply devices can be used if the device power is low or the wiring cable is long. Step two: program the bus-line devices and test the alarm system before installation Encode all the modules (Note: The code of the module is encoded in binary, that is, all the code on the digital side; ensure no repeat for the codes.) Wire the module to alarm panel (without detectors). Test with a multimeter to ensure each module all 4-wires are connected with alarm panel and no short-circuit. Red and black wires are power supply of positive and negative terminal. Parallel connect a 2.2K resistor to each hard-wired zone of alarm panel. Series connect a 47K resistor between black wire and yellow wire of bus-zone module. Use the bus-driver FC-7430 to enable using of FC-7401 and other bus modules. Firstly, please insert FC-7430 into FC-7448 main board, insert a double color 2-wire line on FC-7430 bus port. Positive and negative wiring should be correct and without short circuit. Insert jumper wire in position of “enable” on FC-7430 board. (Back insert the jumper wires to disable after programming finishing.) AC power is supplied for FC-7448. Set zone quantity and zone functions for FC-7401 bus modules using. Zone address is set from 0039(zone 9) and from 0415. For example, 10 pieces FC-7401 will be used, then set zone function from 0039-0048 and enable using FC-7401 from 0415-0419 Program FC-7401 Without FC-7401 connected, press 9876#0 to enter programming process, then enter 9995#, keyboard displays: Checking Multiplex Bus It means inspecting bus interfaces, if failure, please turn off the power and re-enter into programming process.

Dangerous gas leakage Alarm Device Installation
The dangerous gas includes combustible gas such as methane, ethylene, hydrogen, natural gas, LPG etc. and toxic gas such as CO, H2S, H2 etc. The dangerous gas is easy produced at industry fields such as chemical factory, oil field and may lead to explosion. Dangerous gas leakage alarm device is needed to monitor and notify people of the dangers and automatically shut off gas or drive electric fan etc. The gas leakage alarm device should be installed correctly for its proper work. Below we will make notes of the alarm device installation. The alarm device can not be installed at place with strong magnetic such as high power electric engine, transformer around. It can not be installed at places where corrosive gases are present. The alarm device is instrument for safety with sound and light display, it should be installed at places where people can easy see and hear then eliminate the dangers in time. There is platinum, palladium and other rare metals on the surface of alarm device probe, it should be taken care of and avoid breaking the probe when installing the alarm device. The installation position of the indoor probe is different according to the density of the detected gas. When the detected gas density is less than the air density, the probe should be installed 30cm from the roof and downward. On the contrary, the probe should be installed from the ground 30cm and upward. When the probe is installed outdoor, the installation position is confirmed according to detected gas density same as indoor installation. But be noted the probe should be installed on the downwind side. Protective casing is needed for alarm circuit connection cable. It is best to add metal hose to the probe wiring. The probe should be with the same level of explosion-proof with the factory. Do not test the detector with high purity gas. After installation and test, be sure to install breathable waterproof cover to protect the probe from water. Industry gas leakage alarm device is high accuracy explosion-proof instrument. It always work with fire alarm control panel or other security system to respond to gas leakage and prevent disaster.
