1. SAFETY AND USAGE CONDITIONS
Prior to the installation please read the following instruction.
Electric installation should be done in accordance with PN-IEC-60364-1 norm by the authorized
person. Installation should not be directly exposed to atmospheric electrostatic discharge.
It is forbidden to connect the panel to other installations, with exception of the application
recommended by the producer.
Electronic cassette should not be exposed to high temperature or humidity.
Self maintenance is only permitted for qualified persons. Device maintenance by unauthorized
persons may result in the lost of warranty.
It is forbidden to connect power supply from sources with different parameters than recommended
by the producer to panel clamps. The producer is not responsible for any lost occurred due the
usage of improper power supplies.
Signals from the digital entry phone system should not be directly connected to RTV sets,
because of risk of devices and system damages.
Do not clean the electronic cassette with gasoline, solvents or strong detergents as it may cause
damage of the device surface.
2. INSTALLATION OF ELECTRONIC CASSETTE AND POWER SUPPLY ADAPTOR
Electronic cassette and power supply adaptor should be mounted inside the building, most preferably
in a place which is not accessible for unauthorized persons. It is recommended to place both devices
in an installation box. The cassette is mounted by means of 4 screws. To the place where the power
supply adapter is mounted supply from power network should be routed.
Electronic cassette casing is fixed to the base by means of two screws.
Wire ends from feeding transformer should be wound on the smaller ferrite core included in the set.
Each wire should be wound 2.5 coils as shown on figure 1. Wire connecting the talking cassette
with electronic cassette should be wound similarly - at the side of electronic cassette the wire end
should be wound on the bigger core. If this is impossible due to the thickness of wire, insulation
should be removed and only those wires which are used for connection should be wound on the
core. Connect the wires according to connection diagram.

3. CONFIGURATION
NOTE!
In the description abbreviations are used - exchange configured for the service of the main entrance
is designated EC-2502/H and exchange for the service of subordinate entrance EC-2502/U.
In entry phone CD-2502 one type of electronic cassette is used - EC-2502. Cassettes are default
configured as EC-2502/U. The use of the device (main or subordinate entrance) is defined by
program.
Support for the main entrance (work in H mode) requires change in cassette configuration parameter
[EtYP] (see programming, page 5). Next pushbutton INIT should be pressed and while still holding
it, pushbutton RESET should be pressed for a while and released. After approx. 2 seconds pushbutton
INIT can be released. Before initialization serial number will be displayed and after that parameters
initialization process will begin - at that time on the display of the external panel quickly changing
digits will appear. When the countdown visible on the display stops, all default settings will be
restored in the cassette and operation mode will be changed.
