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, an exit delay or an auto-arming
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).
