FEATURES OF ENTRYPHONE SYSTEM CD-2500
For the installer
1.Two-wire installation. All the uniphones are connected to the electronics cassette
through the agency of a two-wire bus
2. The possibility of connecting up to 254 subscribers to one standard electronics
cassette
3. Small dimensions of the conversations cassette, providing for simultaneous
selection of flat numbers within the range of 1-999
4. Servicing and installation procedures which make for easy installation and possible
repairs of the interphone system.
5. The possibility of controlling the electro-catch or the electromagnetic lock.
For the investor
1. Illuminated keyboard without mechanical contacts.
2. High resistance to mechanical damages. The conversations cassette in the CD-
2500 system has been additionally reinforced in order to minimize the risk of
destruction of the equipment in result of vandalism.
3. Protection from noxious influence of atmospheric conditions.
4. Low cost of the equipment calculated per one resident. The possibility of servicing
254 residents, simple installation of the equipment and small dimensions of the
conversational cassette are decisive for low price of the equipment in case of
installation in buildings with big number of residents.
5. The possibility of construction of multi-output systems with separated main input
(e.g. leading onto the premises) and secondary inputs. This solution entails the
application of special electronics cassettes.
6. Electronic key with a Dallas pellet. Real estate administrators and their subordinate
services can use one key for entry into all the facilities under their supervision. The
key is equipped with a unique number which is very difficult to counterfeit; on the
basis of this number the key reader makes its identification.
For the user
1. Code lock function. Allows for entering the premises without the necessity of using
keys.
2. Key with a Dallas pellet. Small dimensions and weight, the possibility of application
in other equipment and systems and the difficulty in counterfeiting the key make it
an attractive alternative to traditional mechanical keys.
3. Lack of possibility of eavesdropping a conversation from other uniphones.
Conversation in the CD-2500 system cannot be performed with more than one
uniphone at a given moment.

1. Components of the CD-2500 System
Conversational cassette CP:
CP-2500/SR - CP panel, color: silver
CP-2500/CZ - CP panel, color: black
CP-2500 TM - panel with Dallas key reader
Conversational cassettes in the CD-2500 system are universal devices utilized both
in the basic system (with one or multiple outputs) as well as in the output hierarchy
system. In the basic version they are designed for assembly under the stucco.
Conversational cassette casing
By standard, the conversational cassettes and the resident lists are supplied in
under-the-stucco frame, the casings allow for mounting these devices over the
stucco. An illuminated number panel is also available, which allows for the resident
list or the address of the premises to be placed.
4101 - over-the-stucco one-segment casing
4201 - over-the-stucco two-segment horizontal casing
4202 - over-the-stucco two-segment vertical casing
4301 - over-the-stucco three-segment horizontal casing
4303 - over-the-stucco three-segment vertical casing
NP4100 - illuminated number panel (resident list)
Electronics cassette EC-2500
EC-2200 - standard electronics cassette
EC-2200/H - primary electronics cassette for multi-entrance systems
EC-2200/U - secondary electronics cassette for multi-entrance systems
Uniphones
The CD-2500 requires the use of uniphones with digital decoder designed and
manufactured by the Laskomex company. One should not use digital uniphones
made by other manufacturers nor uniphones designed for multi-wire analog interphone
systems. The Laskomex company offers five models of uniphones designed for
digital interphone systems CD-2000, CD-2500, CD-3000: LF-8, LX-8, LT-8, LR-8,
LM-8,.
Feeder
TR 2300 - power supply transformer for CD-2500 exchange
Battery
it is possible to connect a battery to the electronics cassette. In case of using a
battery, one should solder in an R69 resistor (27 0hm/0.5W) on the electronics
cassette plate. This solution should be applied in case where short power supply
tension decays are projected. We recommend to use a battery of capacity not bigger
than 7 Ah.

Electrocatch or electromagnetic lock
The entryphone system allows for control of an entrance blocking device: an
electrocatch or an electromagnetic lock. The time of releasing the electrocatch or
electromagnetic lock is set up by program with the use of an appropriate procedure.
These devices are connected directly to the conversational cassette. It is recommended
to use 12V AC/DC electrocatches with current intake not exceeding 0.7A for alternate
current and 1A for direct current can be used.
Door opening button
The button is used at releasing the electrocatch or electromagnetic lock upon leaving
the facility. As a button, any short-circuit button, such as bell button or raid button
used in alarm systems.
Additional calling button
The module allows for additional (acoustic or optical) signaling of calling in the
uniphone. It is used in a situation when the uniphone is located in a compartment
with high noise level, or persons with hearing deficiency are in it. It allows for the
activation, for the time of the calling, of any equipment powered with 12...24V voltage
 a bell, a siren or a signaling lamp.
2. Configuring the Interphones Operation
Basic system.
In the basic system, the interphone consists of electronics cassette EC-2000,
conversational cassette CP-2500, power supply feeder and uniphones (up to 254).
It allows for establishing communication between the conversational cassette mounted
at the entrance and one of the 255 uniphones mounted in apartments. All the
functions of the CD-2500 entryphone are available.
Multi-entrance system with entrance hierarchy.
Multi-entrance system is used in case two entries lead to the given apartment or
group of apartments. It is also applied in separated housing estates with one common
entry secured by an entryphone, and independently protected entrances to buildings
or staircases. The construction of such system requires the application of a system
of electronic cassettes designed specifically for that purpose: EC-2000/H servicing
the conversational cassette at the main entrance and EC-2000/U servicing the
conversational cassette at the secondary entrance.
In the multi-entrance system, main entrance is highlighted (e.g. entrance to the
enclosed housing estate area), from which connection can be established with each
of the apartments, as well as subordinate entrances leading directly to an apartment
or a group of apartments (e.g. entrance to the staircase).
3 Operational mode of the entryphone system CD-2500
Normal mode
In normal mode, the uniphones physical number (programmed by jumpers) matches
the logical number (the one at which the uniphone responds after its number is
selected from the keyboard). This is the default operational mode.
Numbering with range transposition mode
The uniphones physical number (programmed by jumpers) does not match its logical

CD- Elementy systemu domofonowego2500
number (the one at which the uniphone responds after its number is selected from
the keyboard).
logical number = physical number + range transposition
Example:
In the facility, apartments with the following numbering shave to be serviced.
Minimum apartment number 310
Maximum apartment number 360
In apartment no. 310 (logical number) we use jumpers to set the physical number
value to 1, in apartment 311 to 2, etc. We set the value of range transposition to
309. Keyboard selection of a number within the range of 310-360 shall cause a
uniphone to ring in that apartment.
Hotel numbering mode
ground floor 001, 002, ... , 010
I floor 101, 102, ... , 110
II floor 201, 202, ... , 210
........................................................
IX-floor 901, 902, ... , 910
In order to attribute numbers fo appartaments to successive numbers wich are set
up in uniphones, is recomended to set up the electronics cassette into hotel numbering.
We use P-2-9-7 program for this purpose and parameter in this program should be
set as 0. Then we have to set range transposition to value wich corresponds to
amount of flats on the floor (there is 10 for example). P-9 program is used for setting
the range transposition and all programs are described in instruction of instalation,
using and programing. Calculation of number wich is set into uniphone in flat number
PXX with hotel numbering mode is calculated according to the following algorithm:
U=P*LL+XX
where:
U- uniphone number
P- floor number
LL- liczba lokali na piêtrze
XX- numer lokalu na piêtrze
For the given example, the numbers at which the uniphones at the apartments have
to be programmed are the following:
001-1 ,002-2, ... , 010-10
101-11 ,102-12,... , 110-20
......................................................
901-91 ,902-92,... , 910-100

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:
All manuals and user guides at all-guides.com

CD- Elementy systemu domofonowego2500
2, 4, 8, 16, 32, 64, 128
To program the uniphones, use suitable jumpers on the uniphone programming
connector. These jumpers should be installed for which the sum of their numerical
values is equal to a number of a given uniphone. Numerical values of the jumpers
and version of series are shown on the printed circuit board. Example: to obtain
uniphone number equal to 12, install jumpers on connectors 4 and 8 (4+8=12); to
obtain uniphone number 45, use connectors 1, 4, 8, 32 (1+4+8+32=45).
NOTE:
Do not program 0 As this setting is not included in the program it may may result
in malfunctioning of the program.
3.4. Connecting uniphones to electronic cassette.
Terminals marked L- L+ are designed for connection of the uniphones to the electronic
cassette. All uniphones in the system are connected to the same two-wires conductor
in parallel. 255 uniphones LF-8 or LX-8 may be connected to the line. Prior to
connecting the uniphone line make sure that the line is not short-circuited. The line
resistance (measured by means of a digital meter) should be at least 100 kiloohms.
Generally, the system is resistant to possible short-circuiting occuring during both
installation and operation. The electronic circuit, however, should not be operated
under short-circuit conditions during a long time as high shortücircuit current results
in increased heat emission and this may disadvantageously affect the system
operation reliability. If the uniphone line is short-circuited during the system operation
error message E-2 is displayed and no call is possible. In this case coded locks
can be used. Connecting the uniphones, pay attention to proper polarity of the line.
For this reason it is recommended to use cable with coded wires.
3.5. Conecting system power supply.
With the electronic cassette and uniphone line connections checked, the system
power supply may be connected. Use the transformer supplied with the system.
It has two secondary windings, one of them designed for supplying the electronic
cassette. This winding has two outputs:
-12V/0.8A -used for 220V +/- 10% mains voltage
-14V/0.8A -used for the mains voltage lower than 220V-10%=198V.
The second secondary winding is used for supplying electric lock catch. It produces
12V/0.8A After the power supply switching on the system counts a time provided
for stabilization of the uniphones (approx. 25s). After the stabilization time the
system is ready for operation. The
stabilization time is counted each time the power supply is switched on. Additionally,
lock is switched on for a moment for test. When time counting is completed, a dot
is displayed at the display right side. The door phone is ready for operation.
Each time the power supply is switched on, a procedure of restoration of predefined
code table can be called by touching fields C+ simultaneosly provided, however,
this function has not been disabled by the program. Refer to section dealing with
the system programming for details.

3.6. Checking of voltages at test points.
Voltages measured between the test points should be as follows:
K1 K3 14-16 V
K2 K3 approx. by 100 mV less than K1-K3
K4 K5 0V
L+ L- 7...9 V, during talk approx. 4.5...6.5 V
The above values refer to the system operating under normal conditions (the system
operative, with connected keypad). The voltages are specified with 20% tolerance.
It is recommended to check voltages at test points in each new installation.
3.7. Error and fault messages.;
Possible errors and defects occuring during the system operation are indicated by
the following messages in the display:
EWhen one of the inferared beams forming the keypad system is defective, the
door phone program will mask this error and the system will operate correctly.
Depending on a set operation mode (during programming) this condition can be
indicated by single E at the display left side.
Err. If more than one inferared beams are defective, Err will be displayed and the
keypad will not accept commands. Depending on a set operation mode the system
is switched over to emergency program and the street-door catch is unlocked
periodically (once every 45 seconds). The emergency mode is also called in the
case of defect of cables connecting the electronic cassette to the control panel.
E-2 on the display indicates short-circuit of the uniphone line, as described above.
It may also indicate defective uniphone, removed from the uniphone cradle. In the
case of this message, check installation for short-circuits. If the error message was
caused by a defective uniphone, find and replace it. Under the rest conditions (no
uniphone selected) current in the uniphone line sholud be lower than 1 mA measured
at the door phone output). During talk this current hould be 30-60 mA. If the current
is greater than 100 mA (irrespective of the line state, i.e. irrespective of whether in
the course of talk or not) the line is shortücircuited. It should be noticed that after
detection of this error the uniphone line is switched on and off periodically to reduce
the power consumption. The line current will therefore change from a shortücircuit
value (above 100 mA) to zero, in 2-3s cycle.
E-0 after the power supply has been switched on - defect of the microprocessor
memory working space. This error is unlikely to occur. In this case the electronic
cassette should be replaced with a new one.
EEr this error can occur during operation on the working storage in which the lock
codes and the door phone parameters are stored. This message indicates the
memory write/read error. Operation during which the error occured should be
repeated. Sometimes it is sufficient to reswitch the power supply.

3.8. Adjustments.
Three adjustment points are accessible in the electronic cassette:
1 -amplification of the microphone signal (potentiometer P2)
2 -amplification of the loudspeaker signal (potentiometer P3)
3 -line balance (potentiometer P1)
The door phone system is supplied factory adjusted but in some cases the system
parameters may require to be adjusted with specific conditions of operation. To
adjust the line balance, call to an uniphone which is connected at approximately
half length of the line. Then adjust the balance
potentiometer so as to get a point for which susceptibility to excitation is the least.
Proceed as follows:
1 . Set the talking circuit volume potentiometers (P2,P3) to positions ensuring
audibility.
2. Adjusting the P1 potentiometer in one direction find a point at which excitation
occurs. Then find the second excitation point adjusting the P1 potentiometers in
opposite direction.
3. Set the P1 potentiometer to central position between the found excitation points.
4. Increase volumes of P2 and P3 talking circuits slightly.
5. Repeat steps 2, 3, 4 until optimum position pf the P1 potentiometer is found,
at which, with maximum settings of volume in both talking circuits, even slight rotation
of the P1 potentiometer causes excitation. Having these steps completed the talking
circuits volumes can be set to required levels. Remember that amplification factors
of the talking circuits should not be too high as excitation effect can occur in uniphones
due to spread of amplification levels of the uniphone microphones. In this case
decrease the microphone amplification level in the uniphone involved, using the
uniphone potentiometer. Recommended procedure for setting volumes is as follows:
-amplification of up circuit (the cassette microphone): set P2 to minimum value
ensuring sufficient audibility in the uniphone earphone;
-amplification of down circuit (the cassette loudspeaker): set P3 to maximum
volume (up to excitation threshold) and then decrease the setting by 20-30 degree.
3.9. Additional notes.
One of the features of the CD-2000 system is that parameters of its operation are
programable. During programming individual digital codes of flats can be changed
and basic operation times (unlocking time, ring time) can be set. The door phone
system functions have been also extended with possibility of disconnection of
individual uniphones or group of uniphones from the system. All settings are
entered from the standard keypad.
