System overview
The Bosch PLENA matrix product range consists of high-quality products and is the ideal
solution to perform zone announcements, with excellent speech intelligibility and background
music, in a wide variety of public address areas.
The system is designed for maximum flexibility to suit almost any application. The installation
of is quick and easy, because the system uses CAT‑5 cables to connect accessories and
amplifiers to the DSP matrix mixer.
PLENA matrix product range comprises:
– PLM-8M8 – 8 Channel DSP Matrix Mixer:
The digital signal processor (DSP) Matrix Mixer is the heart of the PLENA matrix system. When
combined with the Call Station (PLM‑8CS) and the Wall Control Panel (PLM‑WCP) making
announcements and controlling individual zones is easy. The multi channel DSP amplifiers
(PLM‑4Px2x) can be connected via STP type CAT‑5 (Amp Link) or via phoenix terminal
connectors. The internal audio matrix can control announcements (via the call station), mix
four mic./line inputs, and select any of the three background music sources and deliver these
to a total of eight independent zone outputs. There is also a logic input for emergency override
that will take priority over all other inputs. Control of the DSP features is via Ethernet
connection and use of the product GUI of Windows or iPad.
– PLM-4P125 and PLM‑4P220 – Multi channel DSP Amplifiers:
With the exception of the power output, both Class‑D multi channel DSP Amplifiers are
virtually identical in features. The amplifiers come with advanced DSP features which are
accessed by the PC GUI. Both amplifiers feature the “Amp Link” CAT‑5 cable connection to
connect easily to the PLM‑8M8 DSP Matrix Mixer. Loudspeaker outputs are for 100 V, 70 V,
8 Ohm and 4 Ohm operation. The amplifier channels can also be bridged together to make
more powerful outputs. The amplifiers also feature an auto standby mode that significantly
reduces the power consumption making the amplifiers more cost effective and
environmentally friendly.

– PLM‑8CS – 8 Zone Call Station:
The 8 Zone Call Station is used to make announcements in designated zone configurations. A
total of 8 call groups can be configured in the DSP Matrix Mixer and activated via the
capacitive touch areas on the surface. The call station is powered via the PLM‑8M8 DSP Matrix
Mixer over standard CAT‑5 cables. The control is over the RS485 protocol, and can be
looped‑through to add more call stations to the system.
– PLM‑WCP – Wall Control Panel:
The Wall Control Panel is used to select and control the volume of input sources within in a
particular zone. The unit can set up to either; select the background music (BGM) input
source, or to mix the four mic./line input sources within a zone. The connection uses the same
CAT‑5 cabling and RS485 protocol as the PLM‑8CS 8 Zone Call Station and is also powered via
the PLM‑8M8 DSP Matrix Mixer. Installation of the wall control panel is via the supplied
wall‑mount bracket.
– PC Configuration and User GUI:
The PC GUI offers a configuration page and user operation page to setup and control the
PLM‑8M8 DSP Matrix Mixer and also the PLM‑4Px2x Amplifiers. The software GUIs are able to
be downloaded from the Bosch website: www.boschsecurity.com.

Call Station
1. A call station is used as a desktop device. As such be careful do not place this product
where it is likely to have liquid spilt on it.
2. Take care to when installing not to exceed the cable manufactures’ “bend radius”
specifications.
3. Be sure that cabling is installed in a way that the cabling will not be damaged, and it will
not become a hazard.
4. Check that RJ45 connectors have strong locking tabs, and are not able to be
inadvertently pulled out once installed. Refer to Call Station, page 18.
Notice!
The maximum number of call station IDs that can be configured for each DSP matrix mixer is
8 call stations.
The maximum safe cable distance from the DSP matrix mixer to the last call station on is
500m. This may be extended with the use of better cable and less call stations on that cable
run.
If the cables are exposed; use black CAT‑5 cables. This makes for a better visual look once
installed, as it matched the black of the call station.

5.3
Wall Control Panel
A wall control panel is installed as a wall/surface mount product that allows two methods of
cable entry. This allows the same product to be used for both; solid masonry walls, where
cables are often run externally down a wall, then enter the unit from above; or alternatively on
frame constructions where cables are inside the cavity and need to be hidden.
1. Be sure to plan for easy cable entry into unit before affixing the bracket to the surface:
– Be sure that there are no electrical cables that will be obstructed or compromised by
the method of fixing the bracket (i.e. screws).
– The textured surface should be facing the wall. This surface texture assists the use of
adhesives if required.
– Be sure that the bracket is level and is straight before attaching to the wall.
– Allow enough space above the bracket so that when attaching the wall control panel,
it is not obstructed.
2. Set the rear panel DIP switches before the wall control panel is locked into bracket:
– Refer to Wall Control Panel DIP switch settings, page 24.
3. Connect the RJ45 connector(s), located on the base of the unit, before the wall control
panel is attached to bracket:
– Be sure to plan and consider the bend radius of cables. It strongly recommended
that the shortest possible RJ45 connector is used when terminating, this is to
maximize bend radius of cables in the confined space.
– Refer to Wall Control Panel, page 18.
4. Place wall control panel onto bracket. Once the 4 lugs have been placed correctly onto
the unit, slide the unit down the bracket until it clicks into place.
– If the unit does not sit correctly into the lugs, be sure that you have not used screw
heads that are too big to fit in the channels on the rear of the unit.
5. Removing the wall control panel from the bracket (if required):
– With the use a flat blade screwdriver press down the bracket locking mechanism,
located on the bottom right hand side, and gently slide the unit upwards, this
removes the unit from the bracket.
Notice!
The maximum number of wall control panel IDs that can be configured via DIP switch is 16 (8
BGM controllers and 8 mic./line controllers). Refer to Wall Control Panel DIP switch settings,
page 24 for more information. The maximum safe cable distance from the DSP matrix mixer
to the last wall control panel on is 500m. This may be extended with the use of better cable
and less wall control panels on that cable run. If the cables are exposed; use black or white
CAT‑5 cables. This makes for a better visual look once installed.

Wall Control Panel DIP switch settings
The wall control panel is designed to control either the back ground music inputs or the mic./
line inputs in one specific zone. As such each wall control panel requires an ID to let the DSP
matrix mixer know which unit (or zone) is requesting a change in source or volume. This is
done via DIP IDs switches to allocate a number to the unit and its function. The DIP switches
are located on the backside of the wall control panel.
– There are two sets of IDs that give the wall control panel different functions:
1. DIP IDs 1‑8 : Line input (background music (BGM)) source selection corresponding to
output zones 1‑8.
2. DIP IDs 9‑16 : Mic./line input select and mic./line mix mode for output zones 1‑8. (e.g.
ID 9 = Zone 1, ID 16 = Zone 8).

8.4.1
8.4.2
Activate the active override audio input function
The active audio override function is used when you want to temporarily override all existing
configurations on all amplifier outputs, with a signal supplied by the override audio input.
1. Trigger the active audio override contact closure on the amplifier rear panel (10) via the
phoenix connection labelled “Active”:
– The override input signal now has a higher priority than all the other input sources,
and is active immediately into all channels.
2. By opening the contact again, the override input signal stops:
– The unit will restore and return to its prior configuration immediately.
Activate the amplifier auto standby
The amplifier auto standby function is used when you want to switch the amplifier to standby
mode. Standby mode activates to save power, which reduces running costs and extends the
lifetime of the amplifier. You can set the length of time that there is no activity in a zone using
the amplifier DSP. The timeout can be as fast as 1 minute or as long as 4 hours (Factory
preset is 60 min.).
1. Once a movement sensor has been correctly connected and powered (8); any activity that
is detected by sensor, resets the standby timeout period.
2. When the timeout has been reached, the amplifier will switch into a highly efficient power
saving mode.
– During standby, if activity is detected via the sensor, or an Active/Alert/EVAC contact
closure is engaged; the amplifier “wakes up” and restore and return to its prior
configuration immediately.
Notice!
The recommended sensor to be used, and can be powered by the amplifier, is the Bosch PIR
range of detectors. Refer to www.boschsecurity.com.

Activate the override input function
The active override function is used when you want to temporarily override all existing
configurations on all outputs, with a signal supplied by the override audio input.
1. Trigger the active audio override contact closure on the units rear panel (7) via the
phoenix connection labeled “Active”:
– The override input signal (8) now has a higher priority than all the other input
sources, and is active immediately into all channels.
– By opening the contact again, the override input signal stops. The unit will restore
and return to its prior configuration immediately.
2. Activate the “Force into override” via the PC GUI:
– The override input signal overrules all active audio signals.
Activate the Alert/EVAC override function
These override functions are used when you want to override all existing configurations in all
zones, with an internally generated alarm signal.
1. Activate the audio override via contact closures the units’ rear panel (7) using an external
device:
– The override input signal overrules all active audio signals.
– By opening the contact again, the override tone stops. The unit will restore and
return to its prior configuration immediately.
2. Activate the “Force into Alert Tone” or “Force into EVAC Tone” via the PC GUI:
– The override input signal overrules all active audio signals.

Amplifier: Fault light lit for
approx. one second.
Amplifier: Fault LED flashes
quickly for around 30
seconds.
Amplifier: Fault LEDs flash
slowly.
– This is indicating
protection on that
channel (overload or
short condition).
– This indicates a thermal
error on the channel.
– This indicates that the
PSU has failed (or
thermally cut‑out).
– The amplifier
automatically retries the
channel after this time (1
min).
– Note that the amplifier
will not detect a shortcircuit directly without
signal - for instance, if a
short is on the output,
but no signal is being
driven, the amplifier may
not actually be in fault
mode. As soon as
enough signal is present
to activate the current
protection the fault LED
will light.
– The channel will be
re‑activated after it has
cooled down.
– Send immediately for
service and/or contact
the Bosch authorized
dealer or installer for
assistance.

The PLENA matrix system has been designed to operate without problems for a long period of
time, with a minimum of maintenance.
In order to guarantee trouble-free operation:
– Clean the units, page 45
– Clean air vents, page 45
– Check the connectors and grounding, page 45
Warning!
Dangerous mains voltages are present inside the 19" units. Disconnect the mains power
supply before you do any maintenance.
Clean the units
Periodically clean all units with a damp, lint-free cloth; never use water or chemicals.
Clean air vents
The multi channel DSP amplifier can collect dust as a result of the internal fan.
Base the interval on the actual situation and dust build‑up. Start with an interval of at least
once a year. Use a vacuum cleaner to clean the air vents of all units.
10.3
Check the connectors and grounding
Periodically check:
– All cable connections for corrosion and the screw terminals to make sure that they have
not become loosened.
– The ground (PE) connection of the system components.
