PRELIMINARY

The European Standards EN 60849 title or “SOUND SYSTEMS TO SAFETY PURPOSES”
indicate clearly the technical principle to apply to in the systems and apparatus involved in a
correct and safety habitats and zones evacuation in case of emergencies status

There are some standards law regulations for sound alarm system . Such sound alarm systems
apply to the alarm messages diffusion is some buildings categories through loudspeakers.

Such systems are obligatory in the following cases:
In schools buildings : schools category 3-4-5- M. L 26/08/1992 (G.U. 16/09/1992 n° 218).
In hospitals, clinics ( M.L 18/09/2002 (G.U. 27/09/2002 n° 27).
The law 626 of 19/09/1994 and M. L 10/03/1998, Official edition G.U. n° 81 of 07/04/1998,
suggest to adopt such sound system for safety evacuation throughout loudspeaker alarm
message diffusion in public habitat accordingly to emergencies risk levels

To apply to such standards, the PA systems for sound/paging and music diffusion must have the
following features :

− Mixer amplifiers control .

− Loudspeakers line efficiency distribution in the various zones involved by the main system.

− Manual and automatic alarm message diffusion.

− Emergency microphone stand (VV.FF.) control.

− Spare amplifier activation in case of amplifier default

− Alarm message intelligibility independently to background noise level.

− Chime tone signal of a duration of 4 to 10 seconds prior alarm message diffusion

− Message pre- recorded and stored in a non volatile memory to ensure the message availability

when necessary.

− The announcement system activation within 3 seconds of the emergency status

− The installation must be subdivided in various zones and can foresee different messages per

different zones

The loudspeakers involved in the system must be fire resistant for at least 30 minutes ( metallic
structure , anti flame cover , ceramic terminal screws etc..).

SYSTEM FUNCTION PRINCIPALS

LINE DIAGNOSTIC

PRO EVAC system is a modular system, for each line there is a zone card to be inserted in the
commutation unit
Diagnostic system inserts in the amplifying chain at regular interval of 1” an unheard pilot tone of
22 KHz. At the amplifier output and at end line loudspeaker, the tone pilot survey is done in a
constant way. In case of this pilot tone absence, the system acts as follows:

1) Tone pilot absence from the amplifier output ( amplifier default) .

− The default indicator on the commutation unit display is switched on

− Main unit default sound signal activation( buzzer).

− Main unit and microphone stands display amplifier default.

− The event is memorised in event log memory and in eventual print purposes when

available.

− Loudspeakers line commutation to back up amplifier – if back up amplifier available-

2) Tone pilot absence at end loudspeakers line (Line default).

− The default indicator of the commutation unit front panel is switched on.

− Main unit default sound signal activation (buzzer).

− Main unit and microphone stands display line default .

− The event is memorized in event log memory and in eventual (when available) print

purposes .

BACK UP AMPLIFIER

PRO EVAC system is designed to connect one or two back up amplifiers to each commutation unit
When only one spare amplifier is connected (SPLIT OFF) all zones modules inserted in the
commutation unit – in case of default- commute audio input and loudspeakers line to the same
amplifier. Statistically it is improbable that two amplifiers are in default contemporaneously. But to
remedy it is necessary to define the back up amplifier to ensure the zones/line necessary power
connect 100V output to terminal BCK 1 OUT and bridge BCK 1 OUT with BCK 2 OUT.
To ensure a good power repartition – in case of amplifier default- it is possible to connect 2 back
up amplifiers (SPLIT ON). In this case the commutation unit is subdivided in 2 groups s of modules
In case of zone 1 to.. 4 amplifier default the loudspeakers lines will be commuted to the first spare
amplifier . In case of zone 5 to ..8 amplifier default , the loudspeakers line will be connected to the
second spare amplifier.

It is necessary to foresee at least one back up amplifier for each commutation unit installed.
It is necessary to reset the system – accordingly to EN 60849 rules- and because the default signal

persists- even if the operating continuity is ensured because the loudspeakers line are connected
to back up amplifier .

The zones modules survey the amplifier default and commute to the back up amplifier, but are not
considered by programming purposes. Zones modules are involved only by general or non
selective call.

LOOP FEEDBACK

The feedback loop line is necessary to check the loudspeakers line continuity. To ensure an
effectual control, the loudspeakers installation must be configured to have one sole line and is
connected to all loudspeakers without derivation ( daisy chain connection) . To the first diagnostic
module must be connected the first loudspeaker and to the second loudspeakers so on …to the
last loudspeaker. To this last loudspeaker must be connected the couple of loop wire .

In this way it is possible to check eventual interruptions due line short circuit as stated in point “j”
paragraph 5.3 of EN 60849 standards.

The line circuit default survey is effected by the diagnostic system but there is no commutation in
case of line interruption (short circuit) . The loudspeakers connected to the line section
continuously connected to the zone module are powered normally ( for example line interruption at
a certain point).

Obviously the system can not check the single loudspeaker status ( not required by EN 60849
standards) at the exception to a great line impedance decrease due to the consequent signal
attenuation and then tone pilot absence.
