Six OMNEO network ports, for loop‑through connections to adjacent devices:
–
Five ports are for copper connection on RJ45, two of them provide Power over
Ethernet (PoE) to supply power to connected call stations or other devices.
–
One port provides an SFP‑cage for Small Form‑factor Pluggable transceivers for
single or multi‑mode glass fiber connections.
Eight control inputs to receive signals from external systems.
Eight voltage free single pole, double throw (SPDT) relay contacts to activate external
devices.
Control input and output functions are software configurable.
Supervision of mains, battery and device operation and all connections; faults are
reported to the system controller and logged.
Automatic battery backup takeover from mains in case of mains failures.
Multiple OMNEO network connection ports, supporting redundant network connections.
Supervised audio lifeline to connected amplifiers, as backup for a failing amplifier
network interface.
Direct connection to the IP‑network.
For redundant network and power connection, a second Network cable should be
connected.
Full color 4.3" capacitive touch screen with intuitive function menu navigation provides
guidance and feedback during the process of live announcements, pre‑recorded
messages and music control. Successful broadcast of announcements/messages and
changes to the background music settings are clearly indicated.
Built‑in monitor loudspeaker with volume control.
Local audio line input (with stereo to mono conversion) for connecting an external audio
source.
Connection of up to four PRA-CSE extensions, each with twelve buttons. The buttons can
be configured for various functions, but they are especially useful for zone selection,
giving a clear overview of accessible zones and the LED indicators for each button show
the status of the respective zone (like being selected, occupied or at fault).
If the call station is not used for a while, it will switch to sleep mode to save energy. It
will immediately wake up when the screen, or a button, is touched.
Press‑to‑talk button gives tactile feedback and is recessed to prevent accidental use.
Press‑to‑talk switch on hand‑held microphone.
Supervision of all critical elements; the audio path is supervised, as well as the
communication to the network.
