enable transmission without interference with other signals in the 868 MHz frequency
band (ABAX 2 system only).

2. Description
Radio communication
The keypad connects to the controller every 4 minutes to give information about its state
(periodical communication). Additional communication takes place:

when the keypad is in use,

in the case of keypad tamper,

when the controller is sending commands to the keypad (wake up and trigger CHIME
signal).
Operating modes
Wake-up
– this mod is started by pressing any key. Additionally, the keypad can be woken
up automatically when an alarm occurs or an entry delay or an exit delay begins (see
description of the “Wake-up” parameter, section “Settings stored in ABAX 2 / ABAX
controller” p. 6). When the keypad is in the wake-up mode, it works in much the same way
as the wired LCD keypad. The display is on. Backlight, LED indication and sound signaling
are enabled.
Sleep
– the mode is entered:
– after 20 seconds since the last key press,
– after preset time, if the keypad has been woken up automatically (see description of the
“Wake-up” parameter, section “Settings stored in ABAX 2 / ABAX controller” p. 6).
The purpose of this mode is to save energy. The display is off. Backlight, LED indication
and sound signaling are disabled (if a time different from 0 is preset for the „Wake-up”
parameter, CHIME from zones will be signaled).
Support for proximity cards
The built-in proximity card reader enables the system to be operated by using proximity cards
(any 125 kHz passive transponder in the form of a card, tag, etc.). If the alarm system is not
to be operated by using the proximity cards, the reader can be disabled (thus reducing the
battery consumption).
Battery status control
If the voltage of any battery is lower than 2.75 V:

low battery information is sent during periodical communication,
