3.4 Connection
Line :
The basic functionality of intercom (voice communication) needs connection of telephone line only. When
you connect the line, the Link Ana iDP announces by sound signal.
We not recommend connecting the Link Ana iDP in parallel with other analog phone.
Attention: The line is necessary to program the Link Ana iDP by the software.
12V Power supply:
The power supply might be AC and also DC, not depends on polarity. For 12V, the max consumption is
250mA. Power supply might be used also for electrical lock powering. Then we recommend power supply
12V/1A.
Attention: The power supply is necessary for the correct operation of the relay.
Relays:
Relays have many possibilities in practice usage. 12V power supply must be connected for correct
operation. The intercom unit has galvanically isolated all-important parts. Telephone line is isolated from
power supply and relays contacts are also galvanically isolated from other intercom electronic parts.
In any case must not be activated directly main voltage 120V or 230V !!! When you need
control main devices please use contactors (power relays) as it is on example
Relays connection examples are mentioned on following page. It is not all of them but give you an
idea how should be connected individual circuits (red rings with numbers = example numbers).
1.
Basic connection - 2 electrical locks and possibility independently control two doors. (Relay mode 1
and 2 m=1) or progressive door opening (relay mode 2 m=5).
2.
Two power supply – possibility to use independently two power supply One for Link Ana iDP and
second for electrical locks. Second electrical lock is connected inversely (fire emergency exit).
3.
Combination of doors with electrical lock and sliding gate at fencing.
4.
Extending of previous example (3) about second doors with progressive opening (this feature is setup
in Time Relay - optional module)
5.
Combination of electrical lock and additional ring. Relay of additional ring might be in mode m=4
(from each button is activated for preprogrammed time) or in mode m=6 (it is activated from one
preset up button for preprogrammed time)
6.
Lighting activation m=3 (for example: way to building) and control of for example: heating up
DAY/NIGHT mode m=8 External power supply required (DIP 3 and 4). Further is necessary use
contactor (Link Ana iDP must not activate 230V!).
Code relay (COSW)
For the first switch is available function code relay (COSW CodeSwitch). It serves primarily to
secure transmission of information by switching the electric lock. When using this function is not possible
connecting or disconnecting the voltage at the terminals to lock this lock activated. Activation is
performed only when positive result compared serial information transmitted between Link Ana iDP and
the board code relay
Link Ana iDP is set in several codes to activate the relay code. Relay can be activated codes for one
or two impulses can differentiate activated from the phone (DTMF) or from keys (keyboard). The last
option is the activation code in another mode switch than the lock.
The code information is 8 bits, but the code is 4 bits with security 4 bits which is total of 8 bits.
Practically, this is performed so that after activation the switch is first transmits the serial code, and if
they agree, so code relay connects the electric lock.
The code relays can be connected in parallel to increase the number of switches, but can never combine
connections electric lock and the code relay parallel!
