Acknowledgement
The automatic acknowledgement after a selective call can operate in different ways. The
acknowledgement mode is programmed at digit 4 of register 033 (EEPROM 1) as follows:
0 = no acknowledgement
1 = acknowledgement with a single tone of 600 Hz, 300 ms
2 = acknowledgement with a tone sequence from register 002
3 = acknowledgement with the identifcation stored last.
Decoder 2
The decoder 2 is coded in register 007 (EEPROM 1). See section EEPROM 1 Programming
Mode. Every 5-tone sequence which has not been identied as correct in decoder 1, is compared
with decoder 2 coding and, in case of digits being programmed with 'F', every tone of the tone
system will be accepted. If the 5-tone sequence bas been identied as correct, the loudspeaker
and the handset are switched on, the loudspeaker lamp flashes, and then the bell tone is
activated. Any further tone sequence check, e.g. by a group call decoder, will not be performed.
An acknowledgement is not transmitted.
Bell Tone
The bell tone volume is programmed at the rst digit of register 040 (EEPROM 1). The setting '1' ...
'9' corresponds to the volume ('1' = lowest level, '9' = highest level). If no bell tone is desired, a '0' has
to be programmed at this digit. See also section EEPROM 1 Programming Mode.
Alarm Switching Output
After successful evaluation the bell tone is generated and the alarm contact is switched for
n*1 seconds. The alarm contact time is programmed in one-second intervals in register 020
(EEPROM 1) as follows:
1. digit
Alarm contact time for emergency call
2. digit
Alarm contact time for normal call (Decoder 1)
3. digit
Alarm contact time for normal call (Decoder 2)
4. digit
Alarm contact time for group call
5. digit
Alarm contact time for conference call
Group Call Decoder 0
The group call decoder 0 is coded in register 005 (EEPROM 1). If this decoder is not required,
please code an 'F' (blank) at the rst digit of the tone sequence. The group call decoder is usually
coded with the same tones as decoder 1. The read-in tone sequence is compared with the coded
tone sequence whereby tone '0' is also accepted. In case of successful decoding the loudspeaker
and the handset are switched on, the loudspeaker lamp ashes, and the bell tone is started. An
acknowledgement is not transmitted.
Group Call Decoder A
The group call decoder A is coded in register 006 (EEPROM 1). If this decoder is not required,
please code an 'F' (blank) at the rst digit of the tone Sequence. The group call decoder is normally
coded with the Same tones as decoder 1. The read-in tone sequence is compared with the coded
