Frequently Asked Questions - Sophia 88665 GEV

How to install the GEV Sophia 88665 intercom?

Installation must be performed by a specialist. Follow the provided wiring diagram. Mount the indoor unit at a height of 140-150 cm and the outdoor unit at 150-155 cm. Connect the wires respecting polarity. Only power on after completing the wiring.

What to do if the monitor does not turn on?

Check that the power supply is properly plugged in and that the mains socket is accessible. Make sure the mains fuse has not blown. If the problem persists, unplug the device and contact a professional.

No image or black screen on the monitor, what to check?

Check that the cable connecting the outdoor unit to the indoor unit is properly connected and that the wire polarity is correct. If you have a second outdoor unit, make sure you are on the correct camera. The screen may also be black if monitoring mode is activated without a second camera.

How to adjust the ringtone volume?

The ringtone volume is adjusted via the function menu. Press the Menu button, then use the Up/Down buttons to adjust the ringtone volume. Confirm with the Menu button. You can also adjust the speaker volume of the outdoor unit (left button, fig. 3A) and the indoor unit (right button, fig. 3B) using a screwdriver.

How to activate night or silent mode?

In standby mode, press the button marked with a speaker icon (). The pictogram changes from blue to red, indicating that Night/Silent mode is activated. No sound signal will sound, but other functions remain active. To deactivate, press the same button again.

Can I connect a second outdoor unit?

Yes, the system can be expanded with a second outdoor unit. Follow the wiring diagram for connection. In monitoring mode, use the dedicated button to switch between cameras. If no second unit is connected, a black screen appears briefly.

How to use the intercom function between two monitors?

Make sure you have two indoor units connected. In standby mode, press the Intercom button () to call the other monitor. The second unit rings. To answer, press the button on the called terminal. Press again to hang up. The conversation lasts about 60 seconds.

How to connect an optional electric strike?

The electric strike must be a memory type (recommended: GEV 07680 or 07697). Connect it to the outdoor unit terminal block according to the wiring diagram: dry contact D/O and GATE. Activation is done via the electric strike button on the monitor. Caution: output voltage is 12 V DC / max. 1 A.

How to clean the intercom?

Use a damp (not wet) cloth to wipe the surfaces. Do not use any harsh cleaning products, solvents, or abrasives. Avoid scratching the camera lens. Do not allow liquid to enter the openings.

What to do in case of persistent malfunction?

Consult the troubleshooting table in the manual: check power supply, connections, volume and brightness settings. If the problem persists, do not modify the device yourself (warranty void). Contact a specialist or customer service.

Do not put screws into the microphone hole. Do not point the video camera directly at the sun or at reflecting surfaces.

Tip: we recommend passing the cables through a protective sleeve to shield them from impacts and weather influences.

Cable connection

Connect the monitor(s) to the outdoor unit(s) and the (optional) door opener with the cables according to the wiring diagram. Carefully insert the wires to the terminals with any small tool taking care that two bare wires do not touch. Make absolutely sure that no bare wires are touching each other after the connection!

(Optional) installation of a door opener

This video doorbell features the option to implement an electrical door opener. This allows you to remotely open a door by pressing the button. For wiring please refer to the diagrams.

Important: it is essential that the electric latch or lock installed has a mechanical memory. We therefore recommend GEV's door opener order no. 07680 or order no. 07697

(Optional) installation of a DIN rail transformer instead of a power adaptor

In case you haven't a power socket close enough near by the indoor unit or you have the opportunity to connect with your house installation, there's the option to replace supplied power adaptor by a DIN rail-adaptor (not included / separately available GEV order. no. 08834402). For installing the DIN-rail adaptor follow the instructions that come along with it.

(Optional) installation of a floor bell and/or an electronical door chime

This unit features several options of adding accessories like an additional door chime or an extra call button (floor bell).

You can either install individually one of the above mentioned accessories or both at the same time.

The floor bell button connection option gives you the freedom of choice to place an additional doorbell button wherever you want. E. g. directly in front of your door or, at a back entrance, etc..

The option for adding an electronical door chime (speaker) allows you to place an external door (chime besides the one built in the indoor unit. In case the built in indoors unit's door chime is not loud enough or too far away you can add an electronical door chime and freely place it wherever required.

Connect the accessory according to the wiring diagram.

Performance Settings

You can adjust the brightness, contrast and colour of the monitor when it is ON by pressing the Menu button (fig. 1) at the side of the monitor.

Extending your system/ Cofiguring your system

Thisy system can be extendend in several ways- e. g. by adding more indoor or outdoor units. Please refer to the wiring diagrams for installation. Please take not of the jumper settings in the wiring diagrams. It is essential that you adopt the Jumper settings according to the information in the diagrams.

The jumpers are to be found on the backside of the indoor unit and are marked with the letters M (Master) and S (Slave). Both Jumper up mean Master unit, both jumpers down mean slave unit.

Care and Maintenance

- Do not store in hot or cold areas. Extreme hot or cold temperatures can shorten the life of electronic devices and can distort/melt certain plastics or may cause malfunction.

- Dropping can result in failure to operate. Circuit boards can crack and may not survive the impact.

- Do not use or store in areas of high levels of dirt or dust. The electronics may be contaminated. Any moving parts will wear prematurely.

- Do not use harsh chemicals, cleaning solvents or strong detergents. To clean, wipe with a damp cloth from time to time.

Recycling Instructions

Waste electrical products should not be disposed of with household waste. Please recycle where facilities exist. Check with your Local Authority or retailer for recycling advice.
