Wiring of standard and magnetic (inverse) lock
6. A special USB cable enables the doorphone to be connected to a PC for programming of
individual parameters. A dedicated Windows program is included on the CD (requires version
W98SE or higher).
2.1.4 Switches
7. The switch number 1 (see figure – 8) activates heating
of the PCB. This is for increased resistance against
humidity. To use this feature you must connect an external
12V power supply.
8. The switch number 2 (see figure – 9) is required for
programming the unit when the password is forgotten. It is
performed by ordinary phone (DTMF – tone dial ).
The switch is
The PCB heating
has two major benefits. Firstly, it warms the board during winter
time (temperatures under -20 C, most circuits have warranty operation down to -20 C)
and secondly it helps to protect the PCB against humidity when installed outside.
2.1.5 Voice level
9. Voice communication – the trimmer position is factory and should be suitable for
most installations. Change the trimmer position only when necessary.
The trimmer "
MIC " is designed for microphone
volume setting. The trimmer " SPK " is designed for
loudspeaker volume setting.
The volume settings are more than adequate for
most situations. Therefore we do not recommend
setting the trimmer position more than
½ . The most
suitable position is 1/3 from minimum amplification.
The trimmer " TRH " is designed for setting the
microphone activation level. It allows balancing
between the microphone and speaker to eliminate
feedback. This setting is also influenced by the noise
of the surrounding environment.
Set up Process: The trimmers MIC and SPK are
set to ¼ position from minimum loudness level (turn
fully anti-clockwise for minimum). The trimmer TRH
is set to a central position. To fine tune, make a test call. Speak quietly, and by adjusting
the trimmer TRH from the central position anticlockwise, your speech should be heard more
clearly by the PBX user. The amplification of the speaker can be adjusted according to your
requirements. Voice interruption might occur if you set the amplification too high. In this
case you can use the trimmer TRH to correct the balance between the speaker and the
microphone.
