Question 1

Can the indoor screen of the LEXMAN SOLAR PANEL WIRELESS VIDEOPHONE operate independently without being connected to the electrical network?

Accepted Answer

No, the indoor screen (the monitor) of the LEXMAN SOLAR PANEL WIRELESS VIDEOPHONE cannot operate independently without electrical power. Unlike the outdoor unit, which has a rechargeable battery and a solar panel, the indoor screen must be connected to the electrical network to function.

Monitor operation: The indoor screen operates exclusively from mains power and requires a power cable to be connected. It does not have a built-in battery or the ability to operate on backup battery. The manual clearly states that if the monitor does not turn on, the first check to make is to ensure that the power supply is properly connected and powered on.

Energy saving: Although the monitor does not operate without being plugged in, it has an automatic standby function. After 20 seconds of inactivity when the device is plugged in but inactive, it enters standby mode. This function reduces power consumption to a maximum of 0.5 W, allowing for energy savings while keeping the device ready for use.

Battery autonomy: Only the outdoor unit (the external unit with camera) has a rechargeable lithium-ion battery associated with a solar panel. This battery can operate independently, but the indoor screen is entirely dependent on mains power. For optimal use, the monitor should remain continuously plugged in.

Question 2

Why does the LEXMAN intercom open my gate but does not allow it to close?

Accepted Answer

The LEXMAN Solar Panel Wireless Intercom + 2 Badges produces a single opening pulse on its gate control contact. The system does not include a programmed active closing function via the intercom. That is why the button opens the gate but does not close it - there is no closing control signal generated by the intercom.

To close the gate, you have several solutions:

Motorization with automatic closing. If your gate motor is programmed with an automatic closing time, it should close a few seconds after the opening pulse. Check the motor documentation or contact the installer to confirm this setting.
Additional closing relay. You can add a separate relay controlling the closing, connected to contacts 3 and 4 of the intercom. This requires modification of the installation and the intervention of an electrician.
Bidirectional motorization in pulse mode. Some motors accept alternating pulses (each pulse reverses the direction). Check your motorization settings to activate this mode, which allows using a single relay for both opening and closing.
Another control system. A dedicated remote control, a wall switch, or another control source can be configured for closing if the intercom does not offer it.

Immediate check: Test if the gate closes automatically a few seconds after each opening. If so, this is the normal behavior of the system. Otherwise, contact LEXMAN support or the installer to configure a suitable closing solution for your motorization.
