Basic Access Easy Controller 2.1

Figure 3.2: Access Easy Controller 2.1
The basic AEC2.1 system consists of a single metal enclosure with three components: CPU, 4-
Reader board, and Power Supply Unit (PSU). Space is provided for a 12-volt standby battery
to sustain the system in time of power failure. The PSU in the controller has an input power of
100~240 VAC. The enclosure is key locked and is equipped with a tamper switch to detect any
tampering of the panel, and/or when the controller door is being opened.
In its minimum configuration, an AEC2.1 system supports one 4-Reader board. The board
comes with, 4 card reader, 8 input, and 8 output ports to support all necessary hardware
(door lock/strike outputs, door contact inputs and request-to-exit inputs). A full AEC2.1
system supports up to a maximum of 16 interface boards (eight 4-Reader boards and eight 8-
IO boards). This allows the AEC2.1 system to support up to 32 card readers, 64 alarm type
input and 64 controllable output points.
CPU Board - The CPU board contains a microprocessor, RAM memory and all necessary
electronic circuitry to interact with other circuit boards. The CPU board also contains the
hardware and software needed to interface to an Ethernet-type network and to communicate
with host computers using TCP/IP protocol.
4-Reader Board - The 4-Reader board is an interface board for AEC2.1. The reader board
contains all circuitry necessary to interface with, and operate, up to four card readers. The
reader board also provides wiring termination points for the readers, door strikes or magnetic
locks, door contacts and request-to-exit devices. The first interface board of the system
communicates with the CPU board via the RS232 channel. The subsequent interface boards
are linked through a multi-drop communication channel, RS485, to form the system. The PSU
supplies the required power to the board.
8-Input-Output Board -The 8-IO board is an interface board for AEC2.1.The 8-IO board
provides the necessary circuitry to monitor 8-alarm type (non-reader) inputs, and to control up
to eight external devices, such as bells, fans, lights, etc. The board also provides wiring
termination points for the input and output devices. The first interface board of the system
