AS-9000 series Alarm Control Host Operation Manual for Bus Line Wiring Installation
Bus Line Wiring Diagram
Single Zone Address Module, Single Zone Address Module With Output, Eight Zone Address Module, Eight Zone Linkage Module, keypad, etc. are connected to the bus line.
Bus Line Wiring Requirements
1, AS-9000 series alarm control host adopts RS485 bus line, wiring to meet RS485 specifications. The signal line is recommended the use of twisted pair shielding RVVS 2*0.5, wire impedance 120 ohms is the best. The maximum control distance of single bus is up to 1.2 km. Connect the GND of all 485 devices with the shielding line. 485 communication using differential mode communication principle, twisted pair of anti-interference is the best. It is extremely wrong not to use twisted-pair lines. (The communication distance of parallel RVV 2*0.5 for the bus line is about 500 meters in the project.)
2, In the same network system, it must use the same cable, minimize the contact in the line. Ensure good welding, bandaged tightly for the contact place to avoid loosening and oxidation.
3, Wiring must as far as possible away from the high-voltage wire, not parallel with the power line, do not bundle together with the power line. (It has 220V power line and RVVS 2*0.5 signal line in one tube in the actual project, but it does not mean that is no problem.)
4, When the bus line length is more than 200 meters, it is recommended to parallel connect a 120 ohm terminal resistor in the last device 485+ and 485-. If the bus line is more than 1.2 km and it plus repeater, it should parallel connect a 120 ohm terminal resistor before connecting the repeater, at the end of the device it also should parallel connect a 120 ohm terminal resistor at the repeater outlet direction.
5, 485 bus wiring must be hand-type bus structure, star-type wiring, and fork wiring are forbidden. Otherwise, a repeater must be added at the fork. (the distance between modules within 5 meters does not belong to fork.)
6, the power supply can be determined according to the installation site:
- Centralized power supply: the wire must be RVV 2*1.5 at least, the distance should be within 500 meters.
- Onsite power supply: use a 12V2A power adapter for each module.
Single Zone Address Module Application - infrared beam
Single Zone Address Module Application – host setting
1, The module occupies the alarm control host zone from 100 to 299. The zone number refers to the number displayed at the keypad when the module alarms, and the zone number = address code +100.
2, Smart search After connecting the line, log on the keypad and enter the "device management \ search bus device" menu, the alarm control host will automatically search bus expansion module and establish a connection, and finally, it will show how many devices found. When increase, decrease, replace the module, the user needs to let the alarm control host search bus expansion module again.
3, Intelligent identification (solve the missing code, recode problem) Each module has its own unique code number. When the same code is assigned to more than two modules, the alarm control host will automatically assign the module starting from 399 to the same code module
4, When the alarm control host prompts XX zone failure, it indicates that the detector is triggered or the signal line is wired incorrectly.
5, On-board 16 wired zones can be turned off directly, if they are not used, choose device management / Host settings / Wired zone / Each zone's alarm election prohibition.
Single Zone Address Module with Output Application - drive siren, flashing light, etc.
Single Zone Address Module with Output Application - switch output (linkage camera)
Eight Zone Address Module Application
Eight Zone Address Module Application – host setting
1, The module occupies the alarm control host zone from 400 to 1999. The zone number refers to the number displayed at the keypad when the module alarms, and the zone number = address code * 8 +400.
2, Smart search After connecting the line, log on the keypad and enter the "device management \ search bus device" menu, the alarm control host will automatically search bus expansion module and establish a connection, and finally, it will show how many devices found. When increase, decrease, replace the module, the user needs to let the alarm control host search bus expansion module again.
3, Intelligent identification (solve the missing code, recode problem) Each module has its own unique code number. When the same code is assigned to more than two modules, the alarm control host will automatically assign the module starting from 1999 to the same code module.
4, When the alarm control host prompts XX zone failure, it indicates that the detector is triggered or the signal line is wired incorrectly.
5, On-board 16 wired zones can be turned off directly, if they are not used, choose device management / Host settings / Wired zone / Each zone's alarm election prohibition.
Eight Zone Linkage Module Application – voltage output (electronic map or siren)
Eight Zone Linkage Module Application – switch output (DVR / alarm receiver)
Eight Zone Linkage Module – dial code
1, When on-board 16 zones need linkage in the alarm system, the dialing switch D1 - D6 on eight zone linkage module is binary code, D7, D8 is not dialed. (Can be linked to 1 - 16 zone)
2, When single zone address module needs linkage in the alarm system, the dialing switch D1 - D6 on the eight zone linkage module is binary code, and the D7 is dialed to on. (can be linked to 100 - 299 zone)
3, When eight zone address module needs linkage in the alarm system, the dialing switch D1 - D6 on eight zone linkage module is binary code, and the D8 is dialed to on. (Can be linked to 400 - 1167 zone)
FAQ
1, The keypad is inoperable.
Processing:
If the bus is dismantled, the keypad can be operated normally. It indicates that there is something wrong with the wiring on the bus line, recheck the wiring.
2, The bus module can not be searched.
Processing:
1), Check whether the front bus module power supply is normal.
2), Check whether the front bus module wiring is normal.
3), If you use the branching device, you only wire 1 branch line and search, then wire the other 1 branch line and search after the first branch line searching is completed.
3, Equipment drop off.
Processing:
1), Check whether wiring meets wiring requirements.
2), Check the power supply and the equipment wiring
3), Replace a new module.
4, Prompt XX zone fault.
Processing:
1), Check whether the zone is triggered.
2), Check whether the signal line is wired correctly.
