2. INTRODUCTION
The mcr 0204 control unit is used in smoke exhaust systems to control the operation of electrical
actuators, in particular the actuators of smoke curtains mcr PROSMOKE FS CE.
The control panel mcr 0204 should be installed near a controllable smoke-exhausting device or in
the facility monitoring room. The control panel is supplied with 230V alternating voltage and working
voltage 24V constant voltage at output to which electrical devices controlling the fire-exhausting
system are connected. The control panel is fitted with the batteries which let the system work in the
case of mains power supply decay. The time of supporting the control panel operation with smoke
curtains PROSMOKE FS CE depends on the number of smoke curtains connected.
Control panel mcr 0204 has the following functions:
alarm triggering by hand from alarm pushbuttons,
automatic alarm triggering from smoke sensors,
automatic alarm triggering from fire-signaling control panel,
informing about alarm (NO/NC signal),
informing about system damage (NO/NC signal),
remote alarm reset and roll-up of curtains,
The mcr 0204 unit features visual indicators of its operating status, repeated on alarm
pushbuttons, which allows easy identification of alarm status or a system defect.
Connecting the fire-exhausting pushbutton mcr RPO-1 allows for remote operation of the control
panel (signaling damage or alarm, remote alarm reset or rolling-up curtains after alarm).

DEFECT
The mcr 0204 control unit is a maintenance-free device. It requires uninterrupted 230 V mains
power supply. In the case of main power supply shortage, the batteries provide emergency power
supply for the period depending on the number of curtains to roll-up (see: OMM for curtains mcr
PROSMOKE FS CE). Any power outage exceeding 72 hours can result in permanent damage to the
batteries.
4.2 Emergency alarm
If the status of the unit is ‘alarm’, the red ALARM diode on the front panel will light up.
Alarm release methods:
Manual - break the glass of the emergency pushbutton and press the button

Smoke and Heat Exhaust Control Unit mcr 0204 for Smoke Curtains mcr PROSMOKE FS CE. User
Instruction Manual.
Strona 7 z 15
Automatic –depending on the type of sensors, the sensors will be automatically activated when the
temperature rises or in smoke conditions.
Control panel mcr 0204 is also able to receive alarm signal from an external source, e.g. fire alarm
control panel through the RPO pushbuttons line.
In the alarm state, the control panel lowers down connected curtains FS CE to the operational
position.
4.3 Deleting the alarm
To delete the alarm status, determine the source of the alarm first. Then remove its cause and
reset the alarm:
Alarm indicated by the pushbutton (the RPO line) - open emergency pushbutton housing, unlock
the button using the lever and delete the alarm using RESET button inside the housing. The red ALARM
diode will go out. The glass also needs to be replaced.
Alarm indicated by a smoke sensor (the sensors line) - delete the alarm using the RESET button,
either in the RPO emergency pushbutton housing or in the control unit. The sensor will not activate
the alarm again if there’s no longer excessive smoke/temperature. The red ALARM diode will go out.
If the cause of the alarm can’t be removed (for example, when there’s an alarm source failure),
disconnect the line corresponding to a particular alarm source. Delete the alarm using the RESET
button. The red ALARM diode will go out. The FAULT diode will light up.
In this case CALL THE SERVICE!
4.4 Rolling-up curtains after alarm release
Resetting with the mcr RPO-1 casing button rolls-up the curtains automatically.
Alarm resetting depends on the settings of SW1-2. In the case the autoreset function is on, the alarm
is reset automatically; if the autoreset function is off, do as above.
4.5 Diagnosing defects
Visual signal (Fig. 1) on the unit’s front panel informs about a system defect. The signal is repeated
in mcr RPO-1 emergency pushbutton.
When only the FAIL diode is on, the batteries have failed. In this case you should check battery
connections and the condition of FS1 fuse (see page 6).
When the FAIL diode blinks, this means that there is no mains power supply. In this case you
should check the status of FS2 fuse (see page 6) and if the 230 V voltage is present on the unit’s
terminals.
The default factory settings for the battery voltage control potentiometer must not be changed!
In case of a system defect CALL THE SERVICE!
4.6 Curtain control –extra information.
The control panel mcr 0204 operating in the curtain automatics mode may have a service button
for temporary lowering of curtains connected to the P4 terminal.
The time of supporting the control panel operation with smoke curtains PROSMOKE FS CE
depends on the number of smoke curtains connected –more details in OMM of smoke curtains mcr
PROSMOKE FS CE.

5. ASSEMBLY AND START UP
1. Mount the unit near the devices which are meant to be controlled by the unit, using
appropriate metal connectors selected in accordance with the substrate material. Note: do not drill
through the unit's housing —in the case of damage to electronic components caused by dust/debris,
any complaint will be disregarded.
2. Sensors line - 2 leads (YnTKSY) from P5 terminals.
End resistor 10 kΩ in the base of the last sensor.
The maximum number of sensors in accordance with the technical parameters.
3. Emergency pushbuttons line (RPO) - 7 conductors from P6, P7 and P14 terminals.
End resistor 10 kΩ in the last pushbutton.
The maximum number of pushbuttons in accordance with the technical parameters.
4. Actuators line - 2 leads (feature PH30, for example HLGs), from P2 terminals. The end terminal
in the last assembly box. The maximum number of actuators in accordance with the technical
parameters.
5. Auxiliary voltage - P7 terminal. The auxiliary voltage output P7 is short-circuit resistant and
may carry a load of maximum two relays.
6. No-voltage output NC (or NO) for information about alarm –2 leads (YnTKSY) from P9
terminals. The jumper H1 allows to select NC output (default) or NO output.
7. No-voltage output NC (or NO) for information about defect –2 leads (YnTKSY) from P8
terminals. The jumper H2 allows to select NC output (default) or NO output.
8. Main supply 230 V, 50 Hz should be connected to the terminal strip P1 on the unit module's
PCB. The power supply for the unit should be separate (units only on the mains line), properly
protected by means of an overload circuit breaker in the switching station.
Do not protect the line by means of a GFCI (RCCB) circuit breaker.
9. 24 V power supply from batteries (P10, P11). The batteries should be connected in series,
taking polarity into account.
10. Start-up. Before switching on the power supply, check if the leads are connected properly.
Note: the leads should be placed and connected in accordance with relevant standards and basic
rules for wiring.
In a correctly operating unit the POWER diode indicator is on.
In order to check the operation of ventilation, the weather monitoring unit should be
disconnected. The weather monitoring unit blocks ventilation for several minutes after the wind has
ceased, and in the case of rain the sensor needs to get dry, which takes even more time.
Note: in order to connect the unit you should use leads which satisfy the requirements of current
regulations.
Note: conduct and connect the cables according to the binding standards and basic rules of
installation assembling.
6. INSTRUCTION MANUAL FOR CHECKING CONNECTION AND
PERFORMANCE OF THE MCR 0204 CONTROL UNIT
For reasons of operational safety and reliability of the fire protection system, after installing the
control panel, check the device by following instructions.
1. Check the correctness and reliability of connection of all cables (main power, input and
output lines, line continuity resistors) in accordance with Operation Manual and the

3. Perform the control panel start-up in accordance with the Operation Manual
(chapter 4.6).
4. Check whether the control panel remains in the normal operating state (chapter 4.1).
5. After min. 12 hours of charging the batteries, check the voltage at the battery terminals.
The measurement must be carried out in the normal operating state (chapter 4.1). The
voltage at the battery terminals should be in the range of 26.5 ÷ 28 V =.
6. Check the correctness of fault detection by the control unit (paragraph 0): damage to the
detector line (e.g. take out the last detector from the socket), damage to the RPO button
line (e.g. to open the RPO line, P6 terminal), damage to the actuator lines (e.g. open the
actuators line, the control panel in mode smoke exhaust), power supply damage (e.g. 230
V disconnect), battery detection (e.g. disconnect the batteries). Tests should be
performed in a normal operating state for any potential damage. In each test case, the
fault condition should be detected and signalled on the front panel of the control unit, on
the service panel for selected faults, by means of the mcr RPO-1 emergency pushbutton
(if connected) and on the fault indication output (by ohmmeter control).
7. Check whether the control panel is correctly detecting alarms. Check all connected alarm
sources:
a) alarm from the RPO line (press the mcr RPO-1 emergency pushbutton),
b) alarm from the detector line (activate the detector),
c) alarm from the external alarm line (activate external device or open the line).
Tests should be performed in the normal operating state independently for each
connected alarm source. In any case, the alarm condition should be detected and signaled
by the control unit (chapter 4.2) on the front panel, on the service panel with the diode
of the proper alarm source, with the diode of the mcr RPO-1 (if connected) and on the
alarm signal output (ohmmeter control), and all connected fire devices controlled by the
control panel should be controlled.
8. Check whether the control unit remains in the normal operating state after all tests have
been performed (chapter 4.1).
9. The control panel can be put into operation if all tests have been completed correctly.
Only an efficient and properly connected control unit can work in fire protection systems.
In the event that at least one result of the above tests is not correct, the control panel
cannot be used in security systems and should be restored for proper operation.
