The Plena Voice Alarm Router is an expansion unit that
can add six zones as well as 12 input and eight output
contacts to the Voice Alarm System. It can use the built-in
amplifier on the LBB 1990/00 Voice Alarm Controller, and
provides inputs and outputs for one or two amplifiers in a
multi-amplifier one or two-channel system.
It provides dual channel operation for calls and BGM
simultaneously to a maximum of six different zones, using
two Plena amplifiers. Additionally, single channel
operation is possible with only one Plena amplifier.
Multiple routers can also share one amplifier, including
the internal amplifier on the controller unit. It is possible
to use any number of amplifiers from one up to the
number of routers used. The controller supports A/B
wiring.
Functions
The LBB 1992/00 has a set of relays for zone-switching
the power amplifier output(s) to different loudspeaker
groups. Each zone can be switched between:
The call channel (call-station selection, all-call
•
microphone, or emergency activation)
The BGM channel (front panel selection)
•
Off
•
Volume override relay contacts are provided for each zone
separately for overriding local loudspeaker volume
controls. This ensures that priority messages go through
with a given volume, even though the local volume
controls may be set to a low volume level for background
music, for example. Both three-wire and four-wire override
schemes are supported. A call or a triggered input will
activate these contacts for the appropriate zones,
together with an additional voltage-free contact (callactive) for control purposes.
An overload protected 24 VDC output provides power for
driving external relays, making an external power supply
unnecessary. The master output channel, or one of the
input channels, can be selected to be monitored with
headphone connector and LED meter.
