INDICATION
S2000-К indication is realized by means of the LCD, the LED indicator, and the audible sounder
(beeper).
The S2000-К LCD can work either in the quiescent mode (also called the Time Display mode), or in
the Command Input mode when the dialog between a user and the system is carried out, or in the
Event Display mode when the S2000-K displays system messages received from the network control-
ler (if the last option is set).
In the quiescent mode the LCD of the S2000-K displays the current time, and the LED indicator and
beeper are turned off.
When the S2000-К is configured to output system messages, the keypad displays these messages on
the LCD screen upon receipting them from the network controller and turns on the LED indicator. To
switch from the Event Display mode into the Time Display mode, press the CLEAR button.
Moreover, if communications between the keypad and the network controller is lost, the S2000-К LCD
displays the message “COMMUNICATIONS LOST” and the keypad LED flashes once per second. In
such a case all user operations with the keypad S2000-K (i.e. typing a password, observing mes-
sages, and requesting access) become unavailable.
In the quiescent mode the S2000-К beeper is turned off. Pressing the buttons on the keypad is ac-
companied by short single beeps. To indicate the results of operations such as an access request or
arming system partitions the beeper has two special beeps:
Success Two short beeps
Error Long single beep
While the S2000-К is operating in the Indicate Alarms mode the beeper is used for indication of alarm
messages (see below). To reset the alarm beep it is necessary to press any button.
The S2000-К LED indicator accompanies messages received from the network controller (if this
mode is set), or indicates loosing connections with it.
