Output Module - Extension Module Type mcr R04xx. Operation and Maintenance Manual.
Strona 3 z 19
1.Introduction
This operation and maintenance manual will make the user familiar with the purpose,
design, principle of operation, proper installation and operation of mcr R extension modules in
versions mcr R0424-1, mcr R0424-2, mcr R0448-1, mcr R0448-2, mcr R0448-4, mcr R0424-
K, mcr R0448-K. The manual includes also additional information about the conditions of use,
maintenance and warranty of the product.
Observance of the recommendations included in technical and user documentation will
ensure proper functioning of the smoke ventilation systems and safety of the system users.
“MERCOR" S.A. reserves the right to make changes in the product or in this document
without notice.
2.Intended use
The mcr R04xx extension modules are part of a smoke control system which also
includes other "MERCOR" S.A. products, such as: mcr PROLIGHT, mcr S-THERM, mcr
ULTRA-THERM point smoke exhaust vents, smoke vents integrated in continuous rooflights
and skylights of the mcr PROLIGHT system, smoke control units mcr 9705 and mcr 0204 and
others.The mcr R04xx extension modules are usedfor the control and supply of 24 V= voltage
to electric actuators installed in mcr PROLIGHT, mcr S-THERM, mcr ULTRA-THERM smoke
exhaust vents, smoke exhaust windows equipped with MCR W or MCR L actuators, mcr
PROSMOKE FS CE curtains (mcr R0424-1, mcr R0424-2, mcr R0448-1, mcr R0448-2, mcr
R0448-4 modules) or to control and supply with 24V= voltage electric motors of mcr
PROSMOKE CE/C1 smoke curtains (mcr R0424-K, mcr R0448-K modules). The modules can
also be used to power other devices (of other manufacturers), only after checking
interoperability and issuing an appropriate
written statement by "MERCOR" S.A.
Making options:
1. mcr R0424-1 1x 24 A output line,
2. mcr R0424-2 2x output lines, 12 A each,
3. mcr R0424-K for curtains, 1÷10x output lines, 24 A,
4. mcr R0448-1 1x 48 A output line,
5. mcr R0448-2 2x output lines, 24 A each,
6. mcr R0448-4 4x output lines, 12 A each,
7. mcr R0448-K for curtains, 1÷10x output lines, 48 A.
The mcr R04xx extension modules are designed to work with the mcr 9705 and mcr
0204 control units, which control the module functions, correctness of its operation (module
status) and continuity of the panel-module and module-actuators lines.
3.Design and operation
The extension modules comprise the following key components:
1. enclosure with module status indicators on the door;
2. supply and battery charging circuits (configuration depending on the module
version, T1, U1, U2, C1, Z1);
3. control system (US);
4. set of relays (number depends on module version, K1÷K5);
5. battery bank (B1, B2);
6. terminal block with fuses (F1÷F6).

Fig. 1. Extension module (on the left - view of the door, on the right - inside the enclosure - mcr R0448-4 version).
The unit's steel enclosure, painted light gray (~RAL7035), is designed for surface
mounting, with the option of leading the wires out from the top or back. The enclosure door are
lockable with a key.
Items 2, 3, 4, 6 are placed inside the enclosure on the mounting plate. Batteries B1,
B2 (items 5) are seated on the bottom of the enclosure and connected to the corresponding
terminals.
The output lines of the device (to actuators) and the battery circuit are protected against
short circuit by fuses; the number of fuses and their rating depends on the module version.
The module also has an overcurrent protection switch F1 for the 230 V~ supply network, rated
at D 10 A. Tab. 1. Fuse rating summary

The device is equipped with indication of the following states:
1. Power supply 230 V~ present - green LED on,
2. Fault - yellow LED on + signal transmitted to the control unit (active in case of:
230V~ mains power failure, batteries missing or discharged, output line
damage).
3. Actuator operation - yellow LED on.
For operation it is necessary to connect the module input to the actuator output of the
mcr 9705 or mcr 0204 control unit. Only one extension module can be used per control unit
actuator output. The modules can be connected in a cascade, i.e. the input of the next module
can be connected to the output of a module.
The module activates the actuators according to the signals from the control
unit at the actuator line output (opens on alarm, closes after alarm reset, opens and
closes for venting).

Output Module - Extension Module Type mcr R04xx. Operation and Maintenance Manual.
Strona 5 z 19
If the 230 V~ mains power supply to the module or the control unit is missing, the smoke
vents can only be opened in the event of an alarm; the ventilation function is blocked to protect
the batteries from discharging.
Caution: do not leave the unit without mains power for more than 72 h with the batteries
connected, due to the possibility of damage to the batteries. In case of using the module to
power mcr PROSMOKE FS CE curtains, this time is up to 6.5 h (see operation and
maintenance manual for mcr PROSMOKE FS CE curtains).
4. Transport, delivery, storage
The modules are delivered assembled in individual packages. Batteries are supplied
separately. The devices should be stored in dry rooms, in temperatures 0C÷40C.
5. Module mounting
The module should be mounted near the devices it controls, in a location that allows
access to the device. During mounting, disconnect all power sources to the equipment being
installed.
Use conductor types compliant with the local regulations, with appropriate cross
sections.
Install the module in the following order:
1. Fix the enclosure to the wall with steel fasteners matched to the substrate
material: fasteners with a minimum diameter of Ø8, e.g. M8, are
recommended (note: do not drill holes in walls through the enclosure).
2. Make electrical connections according to the attached diagrams (connect
control units, actuators, line termination resistors).
3. Connect the unit to the mains supply. Attach the connectors to the battery
terminals. Turn on the overcurrent circuit breaker inside the enclosure. The
230 V~ LED should light up. The ACTIVE and FAULT LEDs should remain
unlit; when connected to the mcr 9705 control unit with door automation
function, the ACTIVE LED will be lit.
4. Verify system operation by sounding the alarm from all available sources.
5. The device is ready to operate after the batteries are charged (up to 48 h
after the first mains connection, if the connected actuators are not used).
6. Operation
The module is basically a maintenance-free device; however, to ensure the efficiency
of the smoke ventilation system the condition of the device should be checked according to
the following list:
1. Check the status of the module's control units - whether they signal any damage
(daily).
2. Check the power supply to the extension modules (every 3 days or so). If the power
supply decay has lasted (or is suspected to have lasted) for more than 72 hours,
an authorised "MERCOR" S.A. service centre should be called to check the
batteries' condition. In case of using the module to power mcr PROSMOKE FS CE
curtains, this time is up to 6.5 h (see operation and maintenance manual for mcr
PROSMOKE FS CE curtains)
3. Verify system operation by activating the alarm signal, then clear the alarm signal.
Check that connected devices have opened and closed correctly (1 time per
month).
