The chime (for breaks) and a stored message (for instance shop closing announcement) can be
started by an external control key (normally open, NO). The corresponding screw terminals are
designated CHIME and MSG (message). They have to be wired against GND. These control inputs
are not supervised and therefore no resistors are necessary.
9.7 Relay Contacts EMY and ERR
The dry contact designated EMY (emergency, normally open, NO) is active during an
announcement via a fireman call station or during a stored alarm anouncement (evacuation) run.
The EMY dry contacts are useful for energising priority override relays for instance. Furthermore
this contact is active on the installation run.
An ERR called dry contact (Error, normally open, NO) is active on all error messages from the
system. This is intended to control indicator lamps for instance.
9.8 Cascading, Master/Slave Operation
If the amount of zones is not adequate, Master/Slave systems can be configured. Up to 10 units
(1 Master and up to 9 Slaves) can be cscaded by 2 RJ45 connectors (CASCADE) in each unit for
simple looping in.
CAUTION!
Each unit (Master and Slave) must have
its own backup amplifier. The backup amps ouput
power must be the same as the most powerful operational amplifier.
All EV-PAGE callstations are to be connected only to the master unit and not to any slave.
However the EV-P4 callstations can be connected to both Master and Slave units and will call to
zones connected to each unit only. It is not possible to make calls via EV-P4 from Slave to Master,
from Slave to Slave or vice versa. Of course EV-PAGE can call in all zones.
If AUX-input, Message and Chime (for breaks) should be started in all systems at a time, the
control contacts and the AUX audio signal inputs have to be paralleled. For activating stored
emergency announcements in Slaves, a separate alarm switch (with resistors for monitoring) has
to be installed each. As an alarm announcement is started in a Master unit, the Slaves will start as
well in zones and with levels as programmed in the particular Slave unit and with sound files as
recorded on their SD-card.
All error messages coming from Slaves will be shown globally in the Master unit as „SLAVE
SYSTEM“ and in the respective Slave with there detected details. Errors coming from a Master unit
will not be shown in Slaves.
The maximum length of the interconnection cable is limited on a few meters only, that is to say all
units have to be mounted into the same rack.
Each unit can be configured as Master and Slave by setting internal jumpers. If one unit only is
used, it has to be jumpered as a Master. Please find below two images, which show Master and
Slave configuration. The yellow arrows point at jumpers to be set, whereas the yellow rectangles
indicate pins which will stay open.
