1. GENERAL DESCRIPTION

1.1 Introduction

Proevac is a modular, digitally controlled, voice alarm system. It’s main purpose is to send spoken, live or recorded, voice
evacuation messages. Proevac was designed and certified according to EN 54-16 specification in order to grant a high quality and
high intelligibility sound.
The modularity and scalability of Proevac allow to configure it in order to be tailored according to the building requirements
thanks to the high number of zone that can be fitted and thanks to the high output power that can be handled by each zone.
The internal four channelmatrix arrangement allow to sent up to four audio contents or general purpose audio messages on
different group of zones.
The system core is the Master EV PROM5Z unit that manages all audio flows and performs the monitoring of the whole setup. All
functions related to the each zone are managed by the EV MCL1Z modules that are fitted into the Master EV PROM5Z and Slave EV
PROS8Z units and connected to an external power amplifier. Thus, each zone has its own dedicated power amplifier that is
managed independently from all others. This feature allows to set up each zone with a power amplifier that b est suits the design
demands of the electrics of the building with a power handling up to 500 Wrms.
The EV PROM5Z Master unit can handle up to 5 zone controller modules and EV PROS8Z Slave unit can be fitted with up to 8 zone
controllers. Slave units are daisy-chained to the Master allowing thus to configure the system up to 108 zones.
Additionally, each Master and Slave unit can handle a spare amplifier that switches over in case of a failure to a zone amplifier.
Each EV MCL1Z zone controller has an embedded memory where two independent messages are stored. Recorded messabes are
triggered by two monitored input contacts. This particular feature allows to send a dedicated alarm message on each single zo ne.
This means that in case of a fire alarm on a 108 zones system, the equipment will play 108 different messages all together.
Finally, each zone module has its own independent volume and tone control.
The monitoring of the loudspeaker line and related power amplifier is achieved with a tone above the audio band through a FFT
algorithm that allows the system to constantly keep under control both amplifier and loudspeakers without interfering with the
voice message or background music that is being played and without them to interfere with the monitoring itself. The monitoring
is so accurate that it able to catch very small variations of the applied load thanks to a sophisticated algorithm that follo ws and
compensates both environmental parameters and load drifts. The monitoring functions of the EV MCL1Z module include a
detection of ground leakage of the loudspeaker line.
Where the design of the voice alarm system foresees loudspeaker line redundancy on some (or all) zones, the main EV MCL1Z zone
controller can be matched to the secondary line controller EV MCL2Z. The main line controller drives and monitors the power
amplifier and manages the first loudspeaker line (line A) while the secondary zone controller takes power from the same amplifier
and distributes it to the second loudspeaker line (line B) performing load and impedance monitoring. In case of a failure to one of
the two lines, the faulty line is disconnected and power is eventually increased on the healthy line in order to maintain a constant
sound pressure inside the room.
All sound contents are processed by the EV PROM5Z Master that acts as a central sorting device from the inputs to the zone
controllers. The master unit has two input ports from two independent groups of microphone stations connected in parallel in a
bus fashion. Each bus carries audio, data channel and power. The Master unit constantly monitors the performance of the
microphone stations through an integrity check of the communication bus. All microphone stations of the Proevac system can be
configured as a voice alarm call station, or for general announcements. In the first case, if a failure occurs in whatever part of
audio or data path, from the microphone capsule to the Master unit, the system will promptly report a fault.
Proevac has different models of microphone stations: EV BME1T and WG-EFM10 have a single direct access key and are typically
used desktop or wall-mount emergency call stations. WG-MTU06 and EV BME10T allow superior flexibility thanks to their
advanced user interface and are both configurable for general announcements or as emergency call stations.
The functions of all microphone station, their access priority to the zones of the system is defined at the time of the configuration
of the whole system through the BEST (“Basic voice Emergency Setup Tool”) software.
In addition to all described functions, the Proevac system can play two or more recorded alarm messages that are common to all
zones. These messages are triggered by two monitored inputs on the master unit. The master unit as an embedded scheduled
message player for non-fire-alarm purposes that may be useful, for example in a shopping mall to play commercials, welcome
announcements, etc… Finally, the EV PROM5Z master unit has dedicated relay outputs for state reporting to other fire devices,
dedicated inputs to report the state of an external power supply and a background music RCA input.

This entire section is dedicated to installer/maintainer only

4.1 Power supply connection

The EV PROM5Z master and EV PROS8Z slaves (if present) must be powered by a 24dv power source coming from an certified EN54­4 power supply and according to the diagram here below. The sizing of the 24dc line shall take into account the current absorbtion
of master, slave unit, microphone stations and zone modules. Please refer to the technical specifications section for these details.
Power amplifiers shall be also powered by, or shall integrate, an EN54-4 power supply.

Wiring of power supplies – Master, slaves and amplifiers.

The figure above show explicitly the positive and negative connection of the power line that feeds the Proevac system.
The power supply line to the amplifies is shown schematically. Please refer to the manuals of power amplifiers and power supply.

Proevac requires a ground connection between the Master (and slaves of present) and the chassis of the rack cabinet where the
system is installed. The rack cabinet must be connected to a strong earth connection of the building.

It is recommended to periodically check the earth connection with appropriated instruments in order not to affect

the performance of the system.

Proevac’s electrical ground (negative pole of system power) is connected to the chassis.

4.2 Installation of the line modules inside the Master EV PROM5Z and Slave EV PROS8Z units

The Master unit has five vertical slots on the back to be fitted with EV MCL1Z and/or EV MCL2Z line controllers. It is essential that
the slots are filled, starting from the left, in the order shown on the figure below.
The figure also shows a valid and a not allowed configuration.

Filling of the zone slots

Allowed and valid setup

Not allowed setup

The Slave unit has eight vertical slots on the back to be fitted with EV MCL1Z and/or EV MCL2Z line controllers. It is essential that
the slots are filled, starting from the left, in the order shown on the figure below.
The figure also shows a valid and a not allowed configuration

Filling of the zone slots

Allowed and valid setup

Not allowed setup

In case you configure a system with a master and one or more slave units, it is not mandatory that the units have all slots loaded.
It is possible and allowed to partially load the master and continue the installation of other line modules inside the first slave, that
on its turn may not be entirely filled and thus additional modules may be fitted in the second slave, etc…
A unit (master or slave) may be even left empty! This gives the system a great configuration flexibility in terms of distribution of
the risk of a failure of a loudspeaker line or power amplifier. To best illustrate this feature, please refer to the following
application note where a 8 zones system setup is analyzed.



APPLICATION NOTE – 8 ZONES SYSTEM

An 8 zones system (with lines A only) is a significant case of study since it is possible to configure Proevac in different

ways according to the requirements of the voice alarm equipment for a specific building. The requirements may be in
favor of the best effort in case of a failure, or look after the best cost/performance ratio. Balancing the risk of a failure for the
Proevac system in this application note, goes through an assessment of the possibility of a fault of one of the main power
amplifiers. As mentioned previously, the master and slave units have the possibility to manage a spare amplifier that will switch
over in case of a failure to the main power amplifier managed by one of the line modules fitted in the unit. Proevac has the
flexibility to optimize the setup in order to achieve the best compromise in terms of cost effectiveness and risk, or at the
extremes, it is possible to configure the system for a maximum economy (with one or no spare amplifiers), or for a minimum risk
with a spare amplifier for each zone, but at a higher cost.

The figure here on the left, describes
an 8 zones, low budget system, but at
the expense of a higher risk. In fact, it
is foreseen only one spare amplifier
(yellow) that will switch over the first
of the eight main amplifiers that will
fail. If a second main amplifier will fail,
no spare amplifier will be available
since it is already in use.

The figure here on the left, describes
an 8 zones system where a good
balance between risk and cost is
achieved thanks to two spare
amplifiers. Four zone modules are
fitted in the master and four in the
slave. Each group of four is served by a
spare amplifier.

Continuing with this logic, it is possible to furtherly distribute the risk by setting up the same 8 zones with one master, t hree
slaves, with two zone modules each and four spare amplifiers. Each spare amplifier will eventually serve just two zones:

 Master EV PROM5Z + 2x EV MCL1Z modules + spare amplifier
 Slave EV PROS8Z + 2x EV MCL1Z modules + spare amplifier
 Slave EV PROS8Z + 2x EV MCL1Z modules + spare amplifier
 Slave EV PROS8Z + 2x EV MCL1Z modules + spare amplifier

In case we want to minimize the risk of rupture of the main amplifiers by providing one spare for each main amplifier, the system
should be setup with one master, seven slaves each fitted with one zone controller and a spare amplifier:

 Master EV PROM5Z + 1x EV MCL1Z module + spare amplifier
 Slave EV PROS8Z + 1x EV MCL1Z module + spare amplifier
 Slave EV PROS8Z + 1x EV MCL1Z module + spare amplifier
 Slave EV PROS8Z + 1x EV MCL1Z module + spare amplifier
 Slave EV PROS8Z + 1x EV MCL1Z module + spare amplifier
 Slave EV PROS8Z + 1x EV MCL1Z module + spare amplifier
 Slave EV PROS8Z + 1x EV MCL1Z module + spare amplifier
 Slave EV PROS8Z + 1x EV MCL1Z module + spare amplifier

Mixed solutions are also implementable.
In case it is believed that 2 zones are at high risk and 6 zones at low risk, the 8 zones system may be setup as follows

 Master EV PROM5Z + 2x EV MCL1Z modules + spare amplifier
 Slave EV PROS8Z + 6x EV MCL1Z modules + spare amplifier

In case one zone is at high risk, 4 zones at “medium” risk and 3 at lower risk:

 Master EV PROM5Z + 1x EV MCL1Z modules + spare amplifier
 Slave EV PROS8Z + 2x EV MCL1Z modules + spare amplifier
 Slave EV PROS8Z + 2x EV MCL1Z modules + spare amplifier
 Slave EV PROS8Z + 3x EV MCL1Z modules + spare amplifier

If the voice alarm system specifications require the redundancy of one more loudspeaker lines (Line A+B) powered by the same
amplifier, the EV MCL2Z will be matched to the main zone controller and the master and slave units will be filled according the
logic explained above and the indications found in section 4.6.

Here an example of a 8 zone system with 5 line A only zones and 3 zones with line A+B and two spare amplifiers:

 Master EV PROM5Z + 2x EV MCL1Z modules + 1x line B EV MCL2Z modules + spare amplifier
 Slave EV PROS8Z + 6x EV MCL1Z modules + 2x line B EV MCL2Z modules + spare amplifier

The installation of the modules inside the master and slave unit is very simple but requires some care when plugging the module in
the internal mainboard.
Remove the slot cover by unscrewing the screws pointed by the yellow arrows.
Slide the circuit of the module inside the dents pointed by the red arrows, then delicately push the module until the frame sets on
the unit’s back panel. Secure the module with the screws that were previously removed.

Installing the zone modules inside Master and Slave units

WARNING!! Do not force for any reason the unit inside the slot! Forcing the module may seriously damage the bus
connector inside the unit!
