SATEL MRU-300 3
The repeater should be installed indoors, in spaces with normal air humidity.
Prior to installation you should plan the arrangement of all MICRA system wireless devices,
whose signals are to be retransmitted. Select the place of installation so that the repeater is
located within the operating range of the devices and, at the same time, the controller /
control panel, in which the devices are registered, is located within the operating range of the
repeater. The radio communication range depends not only on the installation location,
but also on the position of the repeater antenna, i.e. on how the enclosure is mounted
(horizontally, vertically, diagonally). Please note that thick walls, metal partitions, etc. will
reduce the range of the radio signal. It is recommended that the repeater be mounted high
above the floor. This will allow you to get a better range of radio communication and avoid
the risk of the repeater being accidentally covered by people moving around the premises.
Installing the device in close vicinity of electrical systems is not recommended, since it can
affect the range of radio signal.
The repeater should be permanently connected to the 230 VAC mains supply. Before you
make the cabling, familiarize yourself with the electrical installation of the facility. Make sure
that the circuit you choose for powering will be always alive. The circuit must be provided with
a 2-pole switch disconnector with at least 3 mm contact separation and/or short-circuit
protection with a 16 A time-delay fuse. The owner or user of the alarm system should be
instructed on how to disconnect the repeater from the mains (e.g. show them which circuit
breaker protects the repeater supply circuit).
1. Loosen the cover locking screws and remove the enclosure cover (Fig. 3).
2. Place the repeater at the location of intended installation.
3. Make an opening for power wires in the enclosure base.
4. Temporarily connect the repeater to 230 VAC mains.
5. Replace the cover.
6. Register the repeater in the system (see: PERFECTA / VERSA control panel installer
manual, MTX-300 controller manual or MICRA module manual).
You do not have to register the repeater but its operation will not be supervised if
unregistered (power failures, lack of presence or tamper will not be reported).
