INT-RX-S
433 MHz KEYFOBS RECEIVER EXPANSION MODULE
int-rx-s_en 07/19
The INT-RX-S expansion module allows you to control devices by using 433 MHz keyfobs. This
manual applies to the module with firmware version 1.04. The expansion module is supported by:
INTEGRA (firmware version 1.05 or newer) / INTEGRA Plus / VERSA / VERSA Plus / VERSA IP /
PERFECTA 16 and PERFECTA 32 (firmware version 1.02 or newer) alarm control panel,
ACCO-NT access control panel.
1. Features
Superheterodyne radio receiver.
Support for up to 248 433 MHz keyfobs (the number of supported keyfobs depends on the control
panel).
Transmissions from keyfobs secured by the KeeLoq code hopping.
Up to 6 control functions available from keyfob.
Expansion module firmware update capability.
Tamper protection in 2 ways – cover removal and tearing enclosure from the wall.
2. Electronics board
terminals:
+12V - power
input;
COM - common
ground;
CLK - clock;
DAT - data.
RS-232 port (TTL standard) for updating the expansion module
firmware. The device can be connected to the computer by using the
SATEL USB-RS converter.

switch.
LED indicator of communication with the control panel:
blinking – data exchange with the control panel;
steady light – no communication with the control panel.
DIP-switches.
The DIP-switches 1-5
are used for address setting. The
switch in OFF position has a value of 0. The values assigned to the
switches in ON position are presented in Table 1. The address is the
sum of values set on switches 1-5. It must be different than that in the
other devices connected to the communication bus of the control
panel.
