15. Priorities
Each audio source is allocated to the following fixed priority levels – 1 = highest, 10 = lowest:
1.
Fire MIC 1 = fireman MIC connected to rear side pluggable screw terminals
2.
Fire MIC 2 = fireman MIC connected to front side DIN-connector
3.
Emergency announcement 1 (EMY1)
4.
Emergency announcement 2 (EMY2)
5.
AUX with request
6.
Message (MSG)
7.
EV-PAGE 80 zone call station
8.
EV-P4 sub zone callstation, 4 zones
9.
Chime
10.
Background music
Running lower priority sources like chime and EV-P4 do not initiate a busy status in the EV-PAGE
call station.
The EV-PAGE callstations among each other have block mode priority, that is to say the first
activated EV-PAGE in a system has priority, all others were busy and blocked.
EV-P4 callstations among each other have no priority. So if keys at two EV-P4 were pushed
simultaneously, both will be active. Please observe the busy signalling LED before pushing a call
key when using an EV-P4.
An active higher priority audio source will trigger busy status, which is indicated by a quickly
flashing busy LED in EV-P4 and by showing BUSY in the EV-PAGEs display.
An EV-P4 sub zone call station connected to a slave unit can make calls in its slave system at the
same time, as another EV-P4 on a master unit shall do. There is no interference one to another.
16. Soundfile Card
All sound files are stored on a SD-card inside the device. The system can play MP3 or wave sound
formats. For MP3 files a bit rate of 128 Kbit/s, sample frequency 44.1 kHz, Mono or more is
recommended, which will provide nearly CD sound quality.
The
sequence of the files on the SD-card has to be absolutely maintained
, since the system
accesses the files on the basis of the sequence:
1.
16 kHz test tone
2.
Preannouncement chime
3.
Emergency announcement 1
4.
Emergency announcement 2
5.

Chime for breaks
In order to edit sound files, first the device has to be disconnected from all power supply, both
mains and 24V DC battery power. After removing the cover, the SD-card can be extracted and
inserted in a SD card slot of a computer.
Concerning the sequence, please be aware that most operating systems (Windows too) do not
show the true sequence. When copying files please proceed as follows:
