4. Installation
Disconnect power before making any electrical connections.
4.1 Selecting a mounting location
The controller should be installed indoors, in spaces with normal air humidity.
Prior to installation you should plan the arrangement of all MICRA wireless detectors which
are to be supported by the controller. The controller should be mounted at a location within
the range of wireless detectors (or within the range of the MRU-300 repeater if it is to be
installed in the system). Remember that thick walls, metal partitions, etc. will reduce the
range of the radio signal.
It is recommended that the controller be mounted high above the floor. This will allow you to
get a better range of radio communication and avoid the risk of the controller being
accidentally covered by people moving around the premises.
Installing the device in close vicinity of electrical systems is not recommended, since it can
adversely affect the range of radio signal.
4.2 Preparing the cabling
Prepare the power cables and the cables you will use to connect the controller to the control
panel and run them to the controller’s installation location. Use an unshielded non-twisted
cable. If you use the twisted-pair type of cable, remember that CLK (clock) and DAT (data)
signals must not be sent through one pair of twisted conductors. For power cables, use
flexible conductors with cross-sectional area of 0.5-0.75 mm2.
The cabling should not be run in close vicinity of low-voltage electrical system wires, and
especially of power cables for high-power equipment (such as electric motors).
4.3 Installation of enclosure
1. Open the controller enclosure (Fig. 2).
2. Place the enclosure base against the wall and mark location of the mounting holes.
3. Drill holes for wall plugs (anchors) in the wall.
4. Make the cable entry opening at the base. The opening diameter must be larger than
5 mm. The finished opening must not have sharp edges.
5. Run the wires through the prepared opening (power cables and cables connecting the
controller with the control panel).
6. Using wall plugs and screws, secure the enclosure base to the wall (Fig. 3). The wall
plugs delivered with the device are intended for concrete, brick, etc. For other types of
surface (drywall, styrofoam), use the appropriately selected wall plugs.

SATEL VERSA-MCU 5
4.4 Connecting the wires
1. Connect the CLK, DAT and COM terminals to the corresponding terminals of the control
panel communication bus (Fig. 4).
2. Connect the power wires to the +12V and COM terminals. If the distance to the control
panel is less than 300 meters, the controller can be supplied directly from the control
panel (Fig. 4). If the distance to the control panel is higher, the controller must be supplied
from another power source, which is located at a closer distance (a power supply or
an expander with power supply).
4.5 Start-up
1. Close the enclosure.
2. Power up the controller.

3. Start the identification function in the control panel (see the control panel installer
manual). The controller will be identified as two devices: INT-RX (address 7) and
VERSA-MCU (address 8).
5. MICRA wireless detectors
The controller supports the following MICRA (433 MHz) wireless detectors:
MFD-300 –wireless water flood detector.
MGD-300 –wireless glass-break detector.
MMD-300 –wireless magnetic contact.
MMD-302 –wireless magnetic contact with input for roller shutter detector.
MPD-300 –wireless passive infrared detector.
MPD-310 –wireless passive infrared detector.
MPD-310 Pet –wireless passive infrared detector with pet immunity up to 20 kg.
MSD-300 –wireless smoke and heat detector.
MSD-350 –wireless smoke detector.
MXD-300 –wireless multipurpose detector.
For information about installation of individual detectors, please refer to their manuals.
A wireless detector must be registered to the controller. You can do so by using the DLOADX
program or LCD keypad. When adding (registering) a detector, you must enter its serial
number. The location of the serial number sticker is indicated in the detector manual.
The data on wireless detectors are stored in the controller. If you connect to the control
panel a controller with registered detectors, during identification procedure, these
detectors will be automatically assigned to the system zones.

For information about installation of the MRU-300 repeater, please refer to its manual.
If you want to register the repeater to the controller, proceed in the same way as when
adding a wireless detector (see “Adding a detector” p. 6). The repeater will be identified as
the MMD-300 detector.
You do not have to register the repeater in the controller but its operation will not be
supervised if unregistered (power failures, lack of presence or tamper will not be
reported).
Information about low battery should be interpreted as AC power supply loss.
