3.3.2 Incoming call
Incoming call is a call into door intercom (generated by person inside the
building). After dialling extension number where is connected door
intercom the door interocm line is ringing. After setup number of rings
the door intercom picks up (parametr 51) and you can talk. Other
possibilities are the same like in case of outgoing call (capture 3.3.1).
First exception is first 10sec where you can dial "# and service password"
(parametr 44). By this you enter programming mode of door intercom.
Second exception is when DIP1 is switch to position (
enter programming mode directly without dialling service password.
Last exception is relay(s) control (parametr 381 and 382). You can by
programming prohibit to control relay(s) from incoming call .
3.4 Acoustic path setting
The principle of setting acoustic paths:
Here we have three parameters 71.72 and 73 Using the interaction of these
parameters can be set to sound in different conditions.
1. quiet environment parameters 71,72,73 are set to 7
2. environment where is a strong ambient noise at the communicator and quiet
environment at the phone. Here is both necessary to reduce the microphone
gain (parameter 72 = 1-3) and also change the ratio of the parameters 71/73
way 73 enlarge the the parameter (parameter 73 = 11-15) and 71 parameter
smaller value (71 = 2-4)
3. environment where is a strong ambient noise at the phone and quiet
environment at the communicator. Here we leave the parameter value of 72
= 7 and 73 and 71 parameters set as follows - parameter71 = 11 to 14 and
73 = 2 to 4
The principle of settin parameters is - signal from the microphone is amplified by
the sum of parameters 72+71 = volume of microphone and signal to the
speaker is amplified by the sum of parameters 71+73 = volume of speaker. To
switch the direction of the ratio is evaluated parameters (threshold) 73/72.
-
If parameter 72 is greater than the parameter 73, thus favoring the
direction from the microphone. We choose when the direction to the
phone is interrupted.
-
If parameter 73 greater than parameter 72, thus favored direction to the
speaker. We choose this if the interrupted sound in the speaker of
communicator.
