OPERATION
When an external panel is calling, the monitor rings the doorbell, flashes the handset, key and monitor icons in succession,
and activates the display, showing the view from the calling panel's camera. A call is answered by touching the handset icon. Once it is
answered, a voice call to the panel is set up, and the handset, key and monitor icons are brightened. Additionally, the volume bar will
light up and the conversation volume control by touching the + and - icons will become active and available. The number of lit LEDs on
the volume bar indicates that current level setting, and the volume bar's total blanking mutes the monitor’s loudspeaker and microphone.
When another monitor is calling (intercom call), the display will not turn on and only the handset icon will flash on the calling monitor.
Intercom calls are handled the same way as panel calls. The default maximum call duration is 4 minutes. After 4 minutes the call is
terminated, and the devices will return to standby mode.
Touching the "–" icon during a call will mute the doorbell (only for the call duration).
Another monitor can be called in the intercom mode when the line is free (the middle volume LED is not flashing) and the call is
activated by touching the handset icon, and then the called monitor address is selected on the volume bar with the + and – icons. The
first (from the left) volume bar LED is the first intercom address, the second is the second address, etc., and when all three LEDs light
up, the monitor will call all intercom addresses at the same time (broadcast call). To call the selected address, touch the handset icon
again and if there is a device with the selected address in the system, the monitor will activate the call. If there is no device with the
selected address, the monitor will give the busy signal and enter the standby mode. If during an intercom call a panel call is incoming,
the intercom call will be terminated and the called monitor will start ringing in the panel call mode.
The monitor has the feature of signalling missed panel calls. When a panel call has not been answered, the monitor icon will
flash in standby mode. To cancel the missed call signal, touch the flashing monitor icon.
The door can be opened (typically by opening the electric lock connected to the external panel) in the standby and call modes
alike. To do this, just touch the key icon. Each door opening is signalled by an audible signal ("beep"). When the line is busy (other users
are calling), the door cannot be opened. If there are two panels in the system, the master panel always has priority and performs all
functions by default, e.g. opens the door or activates the call in the standby mode. However, during a call and conversation the picture
from the calling panel will automatically appear and you can only use this panel to open the door.
The monitor supports the so-called auto-opening feature. The feature automatically activates the electric lock upon calling the
monitor (from the panel), e.g. during office hours.
The auto-opening is enabled by touching the key icon for at least 5s. The feature activation will be confirmed by four quick beeps and
brightening of the key icon. The auto-opening is disabled in the same way - by touching the key for at least 5s. When a monitor with the
auto-opening feature enabled is called from the external panel, it will ring a single doorbell and activate the electric lock in the panel. With
the auto-opening feature enabled all monitor features (except receiving calls from the panel) are still available.
The view (from the master panel camera) can be displayed at any time provided that the line is free (no other users are calling
- the middle volume LED is not flashing). To do this, touch the monitor icon - the view will display in ca. 10 s. If an optional camera switch
module is installed in the system, any subsequent touch of the monitor icon will switch the cameras. The view can be displayed
permanently (for ca. 60 minutes at maximum, afterwards the view will turn off automatically). To do this, touch the monitor icon for at
least 5 s. The feature activation will be confirmed by five quick beeps and brightening of the monitor icon. The view will be displayed
until turned off - by touching the monitor for at least 5 s or until calling any monitors from the panel.
A monitor interoperable with other monitors in the system indicates the busy line occurrence. This is done by blinking the middle
volume LED. The line is busy at the time of a call from the panel to another monitor or between other monitors.
When the line is busy, no intercom call can be set up, and neither the view, nor the electric lock can be activated. Only the optional I/O
module can be controlled.
When attempting to enable a locked feature, the monitor will beep three times and will not execute the command.
Similarly signalled is a bus error preventing the proper operation of the system. If an error is detected, the monitors' handset,
key, and monitor icons are blinking. Then, only the view from the panel camera can be displayed. It is not possible to start the electric
lock cannot be activated, the I/O cannot be controlled, and no call can be made.
If the doorbell (RING) feature is enabled, each pressing of the button (connected directly to the monitor or to the PRO-I/O module)
will play the doorbell melody.
