QN-5016 120 bus alarm host

Special attention
1: Using RS485 alarm host: It is recommended to use 2 * 0.5RVSP two core 0.5 square twisted pair cables with shielding layer! Below 500 meters, there is no need for shielding, and a switch power supply is used for centralized power supply. The thicker the power supply line, the better, and it cannot be less than 1 square meter, which is responsible for causing voltage attenuation;
2: Beyond 500 meters, to avoid voltage attenuation caused by centralized power supply, it is recommended to use on-site power supply; RS485 must use 2 * 0.5 square twisted pair shielded wires; The maximum signal transmission distance of RS485 bus is 1200 meters. After exceeding 1200 meters, your company's RS485 signal amplifier will be added to extend the distance;
3: RS485 can also use Ethernet cables to transmit signals, but it is only recommended for indoor wiring; Using standard pure copper network cables to avoid signal interference, it is recommended to use shielded network cables;
4: RS485 adopts a hand-in-hand wiring mode and does not support star wiring; Use your company's RS485 signal isolator to solve the problem of star routing;
5: RS485 supports fiber optic transmission; The transmission optical transceiver must be a half duplex bidirectional data transmission optical transceiver (with reverse data);
6: Special attention should be paid to not wiring RS485 together with audio signal transmission systems to avoid signal interference!
Feature Overview
Adopting embedded system design, 32-bit ARM processor, faster running speed, and ultra large capacity design.
1 dedicated keyboard interface, designed to connect to output devices such as keyboards, printer modules, and linkage control boards, accelerating alarm processing speed.
Two communication interfaces have been implemented, enabling dual bus transmission of 2.4KM without the need for any repeaters.
Maintenance free lead-acid battery intelligent charging control circuit, real-time monitoring of the battery, overcharging, overdischarging, PWM charging control, maximizing battery life.
One 800mA auxiliary output; 1 alarm signal interface with power supply, capable of providing a maximum current output of 800mA; 1 keyboard power output, capable of providing 800mA current output; All outputs are equipped with electronic fuses for overcurrent protection.
The motherboard comes with 8 wired defense zones, and detectors near the host can be directly connected to these zones without the need for additional expansion modules.
Real time clock with backup, running normally after power failure.
Up to 32 keyboards can be connected, operated independently, with a Chinese character interface, and device and defense zone names can be freely changed.
32 subsystems; Each subsystem has 2 automatic deployment and removal worksheets, totaling 64 automatic deployment and removal worksheets; 60 time driven tables, each group of time driven tables can be set to execute up to 3 events (defense zone deployment/removal, defense zone bypass/recovery, output closure/disconnection), which can achieve unmanned operation.
60 sets of passwords, 12 levels of password permissions, can achieve independent control by system, subsystem, device, and defense zone, meeting various control requirements.
Multiple programmable intelligent linkage, realizing functions such as electronic map, DVR alarm input, on-site alarm, etc. Each defense zone supports up to 3 linkage outputs, supporting alarm linkage, deployment and removal linkage, abnormal linkage, etc.
Application modes such as perimeter defense, emergency assistance, hotel services, and fire alarm can be selected to achieve rapid system configuration.
Real time printing function, which can achieve alarm and real-time printing of all operations.
1500 historical records and 1500 operational records. All operations are stored in real-time for easy querying.
Evacuate/deploy through keyboard password, remote control, phone, and central computer
It can be connected to the alarm center through the Contact ID protocol via a telephone line and can notify users by phone

Easy to install, debug, use, and maintain.
