Installing Your Video Doorphone

A: Moundoor unit (surface mount)

  1. Take the rainshade and use it to mark the drilling holes on your wall. Make sure that you are able to reach this place from the back with the 2x 4-wire connectable (and the door lock cable if applicable) to link it to the monitor. We recommend an amount of between 1,35 and 1,70 meters. Try to avoid direct sunlight or rain as much as possible.
  2. Put the 4-wire cable with the connector through the rectangular hole in the rainshade and connect the cable plug to the slot. If you want to use exis wires, make sure you have at least 8 x 0,5 mm and ask a professional electrician for support.
  3. Optionally can connect an electric door lock.To connect a door lock you always use 2 x 0.1 mm² cables. Refer to the wiring instruction diagrams in the “Adding a Door Lock” section.
  4. Remove the aluminum alloy panel with the bus screw; take out the nameplate paper, note your name, and put it back in. Then put it into the rainshade with the top side first and fix it with 2 screws at the boom.
  5. Unfasten the screw behind the camera lens and manually move the camera into the desired position for the best view; then fasten the screw firmly.
  6. Put the aluminum alloy panel back and fix it with the bus screw through the hole in the rainshade.B: Mounting the indoor monitor
  7. Use the mounting to mark the drilling holes on your indoor wall and fix it to the wall, so that the 4wire cable and the power cable (plus extra wire for door/gate lock) can go through from the back.
  8. Connect the 4 wire cable to slots number 1-4:• 1 Audio wire (brown)• 2 Ground wire (green)• 3 Video wire (black)•  4 Power wire (blue)The wires must be in the same order as in the outdoor unit (check wiring diagram in the “Adding a door lock” section for details)
  9. Lastly insert the power cable and hang the monitor on the mounting bracket. Your new Video Door Intercom is now ready for use. In case you want to use exis wiring, ensure you have at least 4 x 0,5 mm² and keep the maximum length of the cables below 50 meters.

Functions of the indoor monitor

When a visitor rings the bell, the chosen ringtone will sound and the picture will appear automatically on the monitor. You can then talk to the visitor by briefly pressing the TALK button on the monitor. By pressing the DOOR UNLOCK or the GATE UNLOCK button, you can unlock your door or gate. If you want to view the picture from the camera without someone having rung the bell, you can press the LIVE VIEW button to see the live picture for approx. 40 seconds.

With the buttons on the side of the monitor, you can select your ringtone, change the ring and talk volume and adjust the brightness and color intensity of the screen, see page 2

An electric door or gate lock is connected to at least 2 x 0.1 mm² cables, available at every DIY store.Note: Check carefully who you give permission to enter your home.Connect an optional electric opener to terminals 5 and 6Connect an optional electric opener to terminals 7 and 8


(A): Mounting the outdoor unit (Flush Mount)If a surface mount is not appropriate (i.e. because you already have an appropriate hole in the wall or for aesthetic reasons) there is the option to mount your outdoor unit with a pre-embedded box. This is an optional accessory that you can find on our website www.elro.eu or purchase from the retailer where you bought the ELRO door intercom. The pre-embedded box has the ELRO Item number DV47EB.To insert the cables from the back or any other side, you need to open one of the pre-arranged holes of the box. Next, fit the box neatly into the wall, screw it firmly and fix it with putty filler.After that, follow the steps described in the surface mount section but fasten the plastic body with 4 screws and the bus screw of the aluminum alloy panel does not go through the box, but directly into the plastic body.
