Table 1: Maximal number of doorphones depending on PBX type


Doorphone connection method is the same for all PBX types, differences are visible only while PBX programming (to know how to programm PBX to working with doorphone, see PBX programming instruction).
SKD doorphones are devices, which enable following activities:

  • dialing PBX extension number to establish call, using touch keypad (phone like),
  • extablish call after dialing doorphone number (listening),
  • switching electro-lock (opening door) directly from phone while conversation, using PIN codes or using proximity identifiers (card or pendant),
  • possibility of connecting additional button or movement detector for opening door,
  • possibility of connecting opening door button,
  • audio status signaling – pressing button, disconnection, etc.,
  • call time duration – not longer than 3 minutes,
  • power supply by save voltage 12VAC or 12VDC,
  • proximity identifiers reader included in doorphone + possibility of connecting one additional (external) proximity reader Slican SKD.CKZ-10,
  • maintenance up to 500 proximity identifiers (users),
  • 2 working modes: local and global.

Doorphone installation

As standard, doorphone can be used for over- and under-plaster mounting. To mount doorphone, front panel should be removed (see chapter 2.1).


Over-plaster installation

Doorphone can be mounted on the outside of wall or column (Fig. 5). Housing for over-plaster mounting should be fixed by three stretcher pins fi 8. Wires should be entered by hole in the back side.

Doorphone connection

Doorphone power supply circuit should include easy to access disconnecting device, which is part of building installation, due to this device it is possible to perform service activities while power supply is on.

If power supply source is included in PBX, which dooz którą bramofon ma współpracować, to do bramofonu należy doprowadzić co najmniej3-parowy kabel[4]:

  • 2 wires (1 para) – connection with PBX analogue port, which works as doorphone port,
  • 2 wires (1 para) – power supply,
  • 1 wire – earthing.

Supply cable should not be longer then 20m and cross-section 0,5mm2 (standard phone cable), while for longer distances wire should be thicker. Voltage drop on wires while electro-lock is on (depends on type of used electro-lock) can causes improper device operation.

Configuration of PBX for doorphone cooperation

To assure proper operation of SKD doorphone, PBX should be apropriatelly configured, analogue port with doorphone connected should be defined as doorphone.

PABX programming method depends on PBX type – see manual attached to the PBX.

Installation of proximity card reader SKD.CKZ-10

SKD doorphone includes proximity idetifiers reader, althiugh it is possible to connect additional reader SKD.CKZ-10. It is mounted to the wall using two fixing bolts 5 and appropriate screws (attached to the set). Mounting surface should be flat. Reader is resistant for moisture, so it can be mounted otside the building.

Io skd reader skd ckz-10.png
Fig. 7: Proximity card reader SKD.CKZ-10

Reader is connected to the doorphone via 8-wires cable, this cable is integral part of reader. All wires are assigned by colours and these colours should be observed while connecting.

Warning! Improper connection can cases improper operation, and sometimes even reader and/or doorphone damage.

Table 3: Connecting reader SKD.CKZ-10 cable to doorphone terminals

Connecting cable is 5 meters long and due to assuring working parameters this cable can't be extend. So distance between doorphone and reader location should be observed. Range of proximity identifiers reader is up to 10cm and depends on type of used proximity identifier (card, pendant).

Doorphone programming

Doorphone working modes

Doorphone can operate in local or global mode. In local mode doorphone is not connected to any other doorphone (RS-485 bus terminals RS-485 bus terminals are not used) in opposite in global mode all doorphones are connected between themselves. Due to such connection parameters changes made on one doorphone are visible in remain doorphones, but only some settings are copy:

  • Access code (code for opening door) – option P12,
  • list of proximity identifiers - option P31.
Io skd doorphone working modes.png
Fig. 8: Doorphones working modes

Used in RS-485 differential transmission protect data against external disturbances (ex. inductive devices – motors), it is recommended to use shielded twisted pair cat.5 (STP cat.5[6]) to assure additional protection. Maximal distance between extreme doorphones cannot be longer than 1200 meters (in extreme doorphones it is recommended to instal JP2 jumper, it is equal to use terminators).

If in global mode on any doorphone in standby status dot on display flashes, it means that connection between this doorphone and MASTER cassette (in this cassette the most current database version is stored) was broken for one of following reasons:

  • damage of RS-485 databus wire
  • no MASTER cassette power supply
Io skd databus.png
Fig. 9 No connection with MASTER cassette signaling

In such situation programming procedure mustn't be executed from doorphone with no connection until failure will be fixed. After fixing this failure standby status dot stop flashing.

Entering programming mode

To enter programming mode:

  1. Press 3 time Io skd key.png button – on display|----| flashes.
  2. Select standard access code to the programming menu: 1234 (this access code is set as default – there is possibility of change this code). Time to entering this code is limited to 10 seconds, starting from first pressing Io skd key.png key. Return to the standby mode (| .| on display) takes place after this time (if access code isn't entered) or immedietelly (after entering wrong value of access code).
  3. |P--| is shown on display, it means that you entered programming mode[7].
Warning! It is also possible to enter programming mode by short closing, for the time of 1 second, pins marked on figure below.


Io skd omitted acces code.pngFig. 10: Entering programming mode omitted access code

Programming options

Warning! Programming mode is marked on display by letter P and signs --.To immediate exit programming mode C key should be pressed..


Programming is base on sellection and setting value of specified doorphone options (P11 to P41). Detailed description of these options is presented in Table 4.

In programming process following keys are used:

1 2 ↑ 3
← 4 5 6 →
7 ↓ 8 9
IioHAS 3000 Kluczyk.JPG 0 C
  • 2 (up) and 8 (down) – option selection,
  • 6 – entering selected option,
  • Io skd key.png (Enter) – entering parameter edition/accepting entered value or selected option,
  • C (Cancel) – return to enter position without any changes.


Warning! If we enter and accept parameter value which is outside the allowable range, existing value displayed once more and edition can be repeated.


Example:

To change programming access code, following steps should be done:

  1. In entering mode select option P41 [after displaying text |P--| on doorphone display, use keys ↑↓ or selecting Io skd key.png key (text |P--| starts flashing), next pressing 41 and accept with Io skd key.png key].
  2. Select option with → key (digit 6) – current value, access code to programm menu is displayed (as default 1234).

Table 4: SKD doorphone programming options

Using access control system

Using doorphone

Doorphone → Subscriber call


Pressing any doorphone key is signaled by single beep, and for digits they are additionally presented on display. From doorphone keypad any extension number can be selected (subscriber or group) or one of digit from range 0..9[8], if doorphone and PABX are properly configured it causes phone ringing of programmed extension number. During dialing, dialed number is visible on display[9] and in the laudspeaker appropriate signal can be heared (it depends on PABX type, where the doorphone is connected). After lifting handset on the phone assigned to dialed extension number call is established. If after the call, subscriber hang on the handset, disconnecting command is sended to doorphone – single beep can be hears in the doorphone laudspeaker and display returns to the standby status (| .|). Call duration time is limited to the 3 minutes – after this time call is disconnected, three beeps can be heared and display returns to standby mode.

When after dialing extension number noone answer this call for a specified time (this time depends on PABX cooperate with doorphone), dialing finishes. Also pressing Io skd c key.png key during dialing causes its finishing (if call is already established, it will be disconnected) and doorphone standby status returns.


Subscriber → Doorphone call


If PABX subscriber dials doorphone extension number, call between subscriber and doorphone is immediately established. During such call (listening) on doorphone display text „CALL” is displayed. If subscriber hangs on the handset after finishing call, to the doorphone disconnection command is sended – in doorphone loudspeaker single beep can be heared,display returns to standby status (| .|). Call duration time is limited to the 3 minutes – after this time call is disconnected, three beeps can be heared and display returns to standby mode. Subscriber will be hear busy signal (the same signal after finishing call by doorphone - by pressing C button).


Opening door


Subscriber can open electro-lock connected to the doorphone, by pressing – on the phone with DTMF dialing - „*” sign (while subscriber press this key in doorphone loudspeaker appropriate signal can be heared), after releasing this key call between subscriber and doorphone can be continued, electro-lock stay open by the programmed time. For instance it is possible to assign to phone speed access code following number: [„doorphone extension number” pause *], dialing this number causes opening door without any conversation.

dditionally it is possible to use opening door button (POD) or movement sensor. In this situation opening door is signal by beep.

Acces control system enables to open door using specially defined access code (see [#Option P12 option P12 in programming mode]). Procedure is as follows:

  1. In btandby mode press Io skd key.png key.
  2. Text ---- is shown on display.
  3. Enter defined access code – on display, instead of digits, appropriate symbols can be seen, due to this security operation access code can't be recognized.
  4. If access code is proper, on the display text OPEn can be seen, this text signals opening electro-lock. Otherwise doorphone returns to standby mode - |----|.

Using proximity card readers

Opening electro-lock using stored earlier proximity identifier is possible in following situations:

  • in any doorphone status (standby, call or dialing) – when using additional reader SKD.CKZ-10,
  • only in standby mode – when using reader included in doorphone.


To do this card (pendant) should be bring closer to the display (there is aerial located around the display) or to external reader. Next unique number stored in card is verified and if this code is equal to one stored in doorphone memory, electro-lock is open – it is signaled by single beep and text OPEn on doorphone display. If verification is negative (no identifier in doorphone database), doorphone signals it by two beeps and electro-lock doesn't open. If as a reader SKD.CKZ-10 is used, mentioned above statuses are also presented using two-colour LED and audio signals, it is described in following table:
