5. Evacuation Mode
In the Evacuation mode, 2N Lift8 (L8) ensures a reliable communication with the evacuation elevator floors, which is crucial for a safe and rapid evacuation of persons in emergency.
The system is controlled by a Central Unit (CU), which provides telecommunication connection of the audio units with an IP phone. Thus, a responsible and duly trained person can communicate with the evacuees on all the floors via an IP phone, ensuring a successful evacuation process.
The floor audio units are connected to a bus (pair of wires) and to the CU via a splitter. The CU is equipped with an internal splitter of its own. Up to 7 additional splitters can be connected to the CU. Up to 8 audio units can be connected to each splitter. Thus, the 2N Lift8 system can serve up to 64 audio units/floors.
The audio units are numbered 1 to 64. 8 positions are allocated for each splitter, see the table below:
| Splitter address | Audio unit count |
|---|---|
| Splitter 1 (CU internal splitter) | 1 to 8 |
| Splitter 2 | 9 to 16 |
| Splitter 3 | 17 to 24 |
| Splitter 4 | 25 to 32 |
| Splitter 5 | 33 to 40 |
| Splitter 6 | 41 to 48 |
| Splitter 7 | 49 to 56 |
| Splitter 8 | 57 to 64 |
Mode Activation
To switch Lift8 into the Evacuation mode, set parameter 996 to 1 (enabled). Refer to S. 3. System Configuration for details.
