The purpose of the elements.
Diode SUPPLY control (green ZAS) – it indicates connection of the power supply
Diode CHANNEL 1 control (red K1) – it signals that the relay 1 is open
Diode K2 (red) – it signals that the relay 2 is open. During learning it indicates the programming procedure
LEARNING button – launches the programming procedures
ANTISABOTAGE – allows for connecting the device to the antisabotage circuit
S output – it is used to connect a acoustic signalling device which informs with short signals whether the relay is
opened or closed, for example while opening the access path to the encryptor or by arming a simple alarm
circuit. On opening the relay on the S output, one short signal is emitted, and on closing it – two signals. The
maximal capacity of this output is 0,5A/12V DC, which is enough even for using sirens with a high level of
audibility. The positive terminal should be connected to +12V and the negative terminal – to the S output on the
terminal strip.

The receiver installation conditions.
We recommend installing the receiver as high as possible, far from any metal or electric devices because the
superreactive receiver is sensitive to electromagnetic interferences. In conditions of high electromagnetic
interferences, using superheterodyne receivers (for example, OPC type) is recommended. The RSU-KO2 receiver
requires dry and closed places.
The transmission code.
The radio transmission, based on the hopping code (KeeLoq by Microchip Technology Inc. USA) guarantees the
high safety of using. Each transmission is different from the previous one. To make the receiver work, you must
enter a remote control into its memory – it is the basic condition.
The remote control can be programmed to unlimited number of receivers. “Loosing” 15 successive transmissions
(using the remote control beyond the receiver's range) requires sending the signal twice (press the remote
control button twice).
The principal use.
The receiver can be used as equipment which controls remotely the work of the following devices: gates and
barriers, electromagnetic locks, lights etc. In alarm systems it is used:
– as a panic button
– as a unit which controls the work of other devices of the system, for example, sensors
– to arm or disarm the system, zones, etc.
Frequency.
The device operates on the frequency 433,92 MHz. In majority of the European Union countries (including
Poland) this bandwidth does not require any special permissions and concessions for using it.
