POPULUS Access Controller

Access controllers are, next to the software, the most important part of access control systems. Access controllers hold the entire logic, which allows safe operation of the access control system, according with instructions that they receive from the program that controls the operation of the system. The Populus access controller ensures power supply for readers of proximity means and communication with them. It can power supply and control the electrical strikes, allows open door control or opening doors with an additional button, IR sensor or IR barrier. It also allows communication with any other access controllers in the system or control program, etc. In addition, the Populus can control other devices in the system (alarm or fire alarm systems, barriers, etc.).

Power supply

The access controller Populus requires 230V AC to operate normally. The built-in power supply (20W) is sufficiently strong to power a contactless card reader and electric strike (12V DC, max. current 250mA), attached to the controller. The power supply has protection against short-circuit currents and current overload. In the event of this protection being activated, the power supply will be switched off for 5s. In this case the LED diode furthest to the left side will slowly signal yellow while the other LED diode will flash red. If this repeats 20 times, the Populus will be switched off until electrical reset (i.e. the unplugging of the device from the mains voltage). The controller detects the overload when the total consumption of all connected devices exceeds 1.5A. Take into consideration that some electric strikes cause very high electrical spikes. Example: If you suddenly open all doors (all electric strikes are triggered), the controller signals an overload condition.

Communication between hardware and software

The access control program installed on the computer (to which the access controller is connected) is responsible for controlling the operations of the controller.

As a matter of standard, there are a number of access controllers in the system, each connected with the others into a communication line (RS485). At the end of this communication line is one of the communication converters from the Spider family. A full line of connected controllers is connected through the communication converter to a computer, on which the program for access control (STOP or V7) is installed and running. A communication converter enables the conversion of signals from the serial protocol RS485 and consequently the possibility of greater distances between the computer and the controllers in the system (up to 1000 cable meters from the computer to the last controller in the line).

RS485

The default communication speed in Jantar systems is 19,200 baud. In order to achieve such speed of data transfer, the length of the UTP, STP or S-FTP cable from the converter to the last controller in the communication line must not exceed 1000 cable meters. If longer distances are desired, it is recommended that communication amplifiers be used. It is also necessary to use one twisted pair for both A and B signals. Only serial connection of controllers in a single communication line is allowed - star connection is not allowed. All S-FTP cable shields must be wired together and grounded at one point. Under no circumstances connect the shield of the cable to the ground of the device!

TCP/IP

Special versions +NET (e.g. Populus 2+NET) have a built-in TCP/IP communication converter. The use of controllers with a built-in TCP/IP communication converter can simplify electrical installation and speed up the system startup. A power supply and connection to the local area network should be provided for each controller. To connect the Populus+NET into the local area network (LAN), use a standard UTP cable with RJ45 connector. The IP address is default and is written on the controller. To change the default IP address of the controller, use the enclosed DS-Manager program. The built-in TCP/IP converter supports communication only of the controller of which it is a component.0 Additional controllers cannot be connected on this converter.

Controlling an electric strike

The Populus can power from one (Populus 1) to a maximum of four (Populus 4) 12V DC electric strikes. The power consumption of the door strike must not exceed 250mA. In order to power alternating electric strikes, Fail Safe electric strikes (reverse operating, when there is no voltage tension on the lock then the lock is open), electric strikes with power consumption higher than 250mA or electromagnetic strikes with increased power consumption, the use of an additional power supply is necessary. If you do not use additional power supply, you agree to take responsibility for any permanent damage of the controller! The electric strike is connected to a controller with a FTP or UTP cable; the maximum distance between the electric strike and the controller is 25 cable meters.

Readers

The access controller Populus is sufficiently strong to power, in addition to the electric locks, from one (Populus 1) to a maximum of four (Populus 4) contactless card readers attached to it. Readers are connected to the controller with an FTP or UTP cable. The maximum distance between the attached controller and the reader must not exceed 25 cable meters. The Populus can be connected to a direct - binary (e.g. R1D) reader as well as to any 26-bit (e.g. R1W I-26), or in some cases 72-bit (e.g. R1W+K I-72), Wiegand readers. Besides contactless card readers, the Populus can also be connected with R4W remote control receivers, R5W fingerprint readers and R1W H-26 readers with higher reading distances (60-100cm).

The Populus can also be used with long-range readers R8W L05-26 (3-6m) and R8W L10-26 (4-8m), which can only read a specific RF passive card C8C (frequency 866MHz). The controller must be a mounted on the safe side of the door (inside the building or place, to which we wish to restrict access). In this event it is not possible to unblock the electric strike and unlock the door by forcibly removing the reader and attempt to reconnect wires with which the reader is connected to the controller.

Internal memory of events

The Populus has its own event memory that is capable of storing information for up to 16,000 users and 8,000 events - depending on the length of individual records. It has a built-in battery, sufficient to power the controller in the event of power failure; data are saved for 24 hours.

Backup power supply

An additional battery (2.3Ah) in the Populus’ casing enables backup power supply for the controller. The Populus also has built-in electronics to charge the battery. The battery is not included in the price of the controller. Normal operation of the Populus does not require an additional battery. In normal operation, when the controller is powered from the mains power, the battery charges up to 13.8V voltage and the LED diode flashes at a frequency of 10Hz. In the event of mains power failure, the LED diode flashes slowly (2Hz). When the Populus is powered with mains power, the actual voltage of the connectors is 12.8V. In the event of mains power failure, the Populus switches to the battery power supply - the voltage of the connectors is between 10V and 13V. The Populus turns off when the battery voltage drops below 10.5V. Backup power supply is primarily intended for the purpose of maintaining the stored data in the event of extended power failure. In such cases, the battery is sufficiently strong for a few releases of an electric strike and does not enable continuous door opening for a long period of time.

Special features

Firmware supports macro commands, automatic functions, the use of a personal pin code, the disabling of readers, integrations, 256 groups, etc. The Populus can operate in both on-line (hardware communicates with the access control and time and attendance program in real time) and off-line (hardware is not connected to the computer all the time – you can use software for system settings, during normal operation time hardware and software are not necessarily connected constantly) modes. The Populus' Firmware is compatible with previous generation of Tiran software (Generation 6), which allows expansion and upgrading of older access control systems to current STOP and V7 programs. The new controllers are factory-loaded with Firmware Version 7. For controllers designed to expand older systems it is necessary to inform us to load them with Firmware Version 6. Carbon Copy technology enables the replacement of old settings with new ones (through the use of a double buffer). This is desired when dealing with a large number of users as the registration of new users would take too long.
