Satel RXH-4K Manual

The RXH-2K/RXH-4K remote controller set enables electrical equipment to be remotely
controlled by means of radio transmitters (remote keyfobs). The remote controller set can
work with up to 340 remote keyfobs. The RXH-2K/RXH-4K only supports SATEL-
manufactured 433 MHz remote keyfobs.
The remote controller design is based on the components of Microchip Technology Inc.
which use the KEELOQ
and the receiver. It ensures both security of use and resistance to spurious control signals
coming from other devices.
Interaction of the RXH-2K/RXH-4K with security systems is facilitated by inputs which provide
information on the system status. They make it possible to easily organize signaling of
arming/disarming, as well as of alarm clearance.

Explanations for figure 1:
1 – superheterodyne receiver, high sensitivity, immune to spurious signals;
2 – LED indicator;
3 – programming buttons (PRG1 – channel 1; PRG2 – channel 2; PRG3 – channel 3;
PRG4 – channel 4);
4 – pins to program the operating mode of relay (MODE1 – channel 1; MODE2 –
channel 2; MODE3 – channel 3; MODE4 – channel 4);
5 – antenna;
6 – tamper contact;
7 – relays (in RXH-2K only 2).
