1. DESIGN AND APPLICATION
The MCT82M-IO-HR is a RACS 5 system terminal mainly dedicated to hotel installations. The primary
function of the device is to provide room entry control and presentation of such hotel signalizations with its
LED indicators as Do Not Disturb, Make up the Room, Emergency Call and Service Call. Besides
mentioned, terminal offers door bell button and programmable built-in IO lines. The door bell can be
signalized on internal buzzer located on any MCT terminal installed in the room or electronic sounder
connected to any terminal’s output. The built-in IOs can be used to control electric equipment (e.g. door
lock, siren, electrical supply) and for connection of additional push buttons, switches and sensors (e.g. light
switches, door contact, window contact).
Along with card holder terminal (MCT82M-IO-CH or MCT86M-IO-CH-HR) the MCT82M-IO-HR can compose
the set of hardware which enables access and basic hotel room automation. The logic of the entire system
is provided by the MC16 controller to which the terminal has to be connected through RS485 addressable
communication bus.
The terminal is offered in two versions: MCT82M-IO-HR for surface mounting and MCT82M-IO-HR-F for
flush mounting.
Note: Hotel system configuration is explained in AN033 application note which is available at www.roger.pl.

Power supply
The terminal requires power supply voltage in range of 11-15VDC. It can be supplied from the MC16 access
controller (e.g. TML output), from MCX2D/MCX4D expander or from standalone 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.

RS485 bus
The communication with MC16 access controller is provided with RS485 bus which can encompass up to
16 devices of RACS 5 system, each with unique address in range of 100-115. The bus topology can be
freely arranged as star, tree or any combination of them except for loop. The matching resistors
(terminators) connected at the ends of transmitting lines are not required. In most cases communication
works with any cable type (standard telephone cable, shielded or unshielded twisted pair etc.) but the
recommended cable is unshielded twisted pair (U/UTP cat.5). Shielded cables should be limited to
installations subject to strong electromagnetic interferences. The RS485 communication standard used in
the RACS 5 system guarantees proper communication in a distance of up to 1200 meters as well as high
resistance to interferences.
Note: Do not use more than single pair in UTP cable for RS485 communication bus.

Bell touch key
The terminal is equipped with touch function key. The key is mainly dedicated to control a bell but it can be
alternatively assigned with other functions within high level configuration (VISO).
LED indicators
The terminal is equipped with four LED indicators which are mainly used to signal hotel functions but they
can also be programmed with other available functions within high level configuration (VISO).

Note: Synchronic pulsing of all four LEDs signifies lost communication with MC16 controller.
Buzzer
The terminal is equipped with buzzer which is used to signal integral functions and it can be additionally
programmed with other available functions within high level configuration (VISO).
Inputs
The terminal offers 3 general purpose parametric inputs type NO/NC/EOL/DW and 1 input internally
connected to tamper contact. Input types and electric parameters such as response time and parametric
resistors are defined within low level configuration (RogerVDM). Input functions are assigned within high
level configuration (VISO). Multiple functions can be assigned to the same input at the same time.

NO type NO input can be in normal or in triggered state. In normal state CA
contacts are opened. Input triggering is caused by CA contacts
closing.

NC type NC input can be in normal or in triggered state. In normal state CA
contacts are closed. Input triggering is caused by CA contacts
opening.

EOL/NO type EOL/NO input can be in normal, triggered or tamper (sabotage)
state. In normal state CA contacts are opened. Input triggering is
caused by CA contacts closing. The change of RTamp resistor
measured resistance in normal state indicates the tamper
(sabotage) state.

EOL/NC type EOL/NC input can be in normal, triggered or tamper (sabotage)
state. In normal state CA contacts are closed. Input triggering is

as the malfunction state.

3EOL/DW/NO and 3EOL/DW/NC
These input types are operated in the same way as 3EOL/NO 3EOL/NC input types with the exception that
masking state is interpreted as triggering of the second input. In VISO software DW input type is
represented by two independent inputs. Each can be used for different purpose and assigned with different
function.
Parametric resistors
The same values of parametric resistors are used for all inputs i.e. 1kΩ; 1,2kΩ; 1,5kΩ; 1,8kΩ; 2,2kΩ; 2,7kΩ;
3,3kΩ; 3,9kΩ; 4,7kΩ; 5,6kΩ; 6,8kΩ; 8,2kΩ; 10kΩ; 12kΩ. Tamp resistor defines a value of resistor used to
detect the tamper (sabotage) state. Alarm A resistor defines a value of resistor used to detect triggered
state. Alarm B resistor defines a value of resistor used to detect an additional triggering state of 3EOL/DW
input type or masking state of 3EOL input type. Alarm A resistor value must differ than value of Alarm B
resistor at least by three positions in the list above. Total resistance of wire used to connect contacts to input
should not exceed 100 Ω. Default values of parametric resistors:
Tamp = 1 kΩ
Alarm A = 2,2 kΩ
Alarm B = 5,6 kΩ
Response time
Response time parameter defines minimal impulse time on the input which triggers the input. Each input can
be configured individually in range of 50 to 5000 ms within low level configuration (RogerVDM).
Tamper detector
Built-in tamper (sabotage) detector enables detection of unauthorized opening of device’s enclosure as well
as detachment of the enclosure from wall. The detector is internally connected to the MCT82M-IO-HR fourth
input. It does not require low level configuration (RogerVDM) and any additional installation arrangements
but it is essential to mount the terminal in such way that tamper lever would properly press the detector. The
detector requires high level configuration which consists in assignment of the function [133] Tamper Toggle
on the level of a Main Board of a controller in VISO software navigation tree.
Outputs
The terminal offers 2 transistor open collector type outputs (15V/150mA rated) and 1 relay output with
NO/NC contacts (30V/1.5A DC/AC rated). Electric parameters such as polarity are configured within low
level configuration (RogerVDM). Function are assigned to outputs within high level configuration (VISO).
Multiple functions with different priorities can be assigned to the same output at the same time.
Identification
By default the terminal reads serial numbers (CSN) of MIFARE cards but it is possible to program cards with
own numbers (SSN) in selected and encrypted sectors of card memory. The use of SSN prevents card
cloning and consequently it significantly increases security in the system. More information on MIFARE card
programming is given in AN024 application note which is available at www.roger.pl.

Installation guidelines
The terminal should be mounted on a vertical structure (wall) away from sources of heat and
moisture.
All electrical connections should be done with disconnected power supply.
If the terminal and controller are not supplied from the same PSU then GND terminals of both
devices must be connected with any wire.
Clean front panel regularly by means of wet cloth and mild detergent. Do not clean by means of
abrasive materials and strong cleaners like alcohols, solvents, etc. Damages to screen surface are
beyond the scope of warranty.
