ESIGN AND APPLICATION
The MCT12E is a series of access terminals dedicated to RACS 5 system. Depending on their versions,
devices enable identification of users by PINs and/or EM125kHz (UNIQUE) proximity cards.
MCT12 is connected to access controller through RS485 interface. Terminal can be installed in outdoor
locations without any additional protection measures.

Power supply
The terminal requires power supply voltage in range of 11-15VDC. It can be supplied from MCX2D/MCX4D
expander of MC16-PAC-KIT, from MC16 access controller (e.g. TML output) or from dedicated power
supply unit. The supply wire diameter must be selected in such way that the voltage drop between supply
output and the device would be lower than 1V. The proper wire diameter is especially critical when device is
located in long distance from the supply source. In such a case the use of dedicated power supply unit
located close to the device should be considered. When separate power supply unit is used then its minus
should be connected to controller’s GND by means of signal wire with any diameter. It is recommended to
use UTP cable for connection of device to controller. The table below shows maximal UTP cable lengths in
relation to the number of wires used for power supply.
