system can be increased.

Loudspeaker zones
A voice alarm controller can serve and manage 6 loudspeaker zones. To increase the number
of zones in the system, one or more Voice Alarm Routers can be connected to the voice alarm
controller. Each router adds a maximum of 6 zones to the system. As the maximum number of
voice alarm routers that can be connected in a system is 19, the maximum number of zones in
a Plena Voice Alarm System is 120 (from hardware and software version 3.x onwards).
Notice!
If older routers are used (version 2.x or higher), 60 zones can be addressed. The
recommendation is to always use 3.x hardware in combination with each other.
Trigger inputs
A voice alarm controller can manage 6 emergency (EMG) and 6 business trigger inputs. To
increase the number of EMG and trigger inputs, one or more voice alarm routers can be
connected to the voice alarm controller. Each router adds a maximum of 6 EMG trigger inputs
and 6 business trigger inputs to the system. As the maximum number of voice alarm routers
that can be connected in a system is 19, the maximum number of EMG trigger inputs in a
Plena Voice Alarm Systemis 120 (from hardware and software version 3.x onwards).
The maximum number of business trigger inputs in a Plena Voice Alarm System is also 120
(from hardware and software version 3.x onwards).
Notice!
If older routers are used (version 2.x or higher), 60 zones can be addressed. The
recommendation is to always use 3.x hardware in combination with each other.
External power amplifiers
The voice alarm router does not have an internal power amplifier. When the power that is
supplied by the voice alarm controller is insufficient, to each voice alarm router two external
power amplifiers can be connected. In a multi‑router system, multiple power amplifiers can be
connected to amplify calls and background music (BGM) or just for backup purposes.
Remote control
With the Voice Alarm Remote Control Extension, it is possible to control the voice alarm router
from another location. The remote control extension is also available as a kit (Voice Alarm
Remote Extension Kit) for creating customized solutions.
