3. Installation.
3.1. Installation of control panel.
The door phone system control panel is mounted either to a building wall or to a
fixed door leaf by means of four screws, using suitable openings in the control panel
rear wall. Large openings are designed for condutors connecting the control panel
with electronic module.
The control panel front plate should be placed in the panel rear part installed on
the wall and then it should be mounted by means of two M4 screws. To protect the
front plate against theft, use two tearable rivets, supplied with the system.
The second version makes possible to mount the front plate by means of screws
screwed from the rear side (mounting in fixed leaf of the door). The keypad uses
7 infrared beams (3 vertical and 4 horizontal) intersecting at places marked with
digits. Interception of appropriate beam pairs when a desired mark is touched
produces a selection signal for a processor controlling the system operation.
If possible, the control panel should be installed inside the house (vestibule,
windshield); outdoor installation should be avoided. Dirt on the control panel (snow,
mud) or flooding it with water may result in incorrect operation of the system until
the control panel is cleaned or dried. Electronic modules controlling operation of
the keypad and display are resistant to temperature variations within the range from
-30o C to +60o C and to normal atmospheric effects.
3.2. Connection of control panel with electronic cassette.
At least six-wire conductor is required to connect the control panel to the electronic
cassette. Special attention should be paid to proper connection of signals to
individual wires of the conductors. This will result in elimination of hum involved
with digital control of the display. Individual terminals are designed as K1 to K6.
The K1 terminal of the control panel is to be connected to the K1 terminal of the
electronic cassette etc.
When selecting the conductor wires for connection of signals, a rule should be
observed that the digital signal paths should be as distant from the analog signal
paths as possible; it is also desirable to have the digital and analog paths separated
by the analog common wire (K5).
Wires of the conductor supplying the electric catch (terminals R+ R-) need not be
screened. If a conductor with greater number of wires is used the non-used wires
are connected to terminal K5-K5. The conductors should be connected with the
power supply switched off.
NOTE:
Incidental connection of the terminals K1 and K2 with the power supply switched
on may result in unrepairable damage of the keypad.
3.3. Programing the uniphone.
Generally, each uniphone is programmed by the wireman with a number corresponding
to a number of a flat in which the uniphone is installed.
If the flat numbers are greater than 254 the uniphone is programmed by assignment
of a successive number in the system and the central unit should be prepared (by
means of suitable installation program) for operation with shifted range.
Each jumper in the uniphone is assigned to numerical value resulting from the
natural binary code.
These values are as follows:
