INSTALLATION and SETUP
Wall mounting the cabinet
Remove the screws that hold the front panel to the chassis. Remove the steel openings on the chassis to route the cables inside
the unit. Drill the wall according to the mounting holes (the chassis itself may be used as a jig)
Screw up the chassis to the wall
Wiring
Depending on the Voice Alarm System model and features, it is possible to wire multiple call stations to the same bus. The
number of allowed call stations depends on the Voice Alarm System that is installed, please refer to its manual for further details.
In case several call stations are connected to the same bus, these are physically wired in parallel. On the electronic board of the
DBEVF call station, two RJ45 connectors are present and these are wired pin-to-pin. The two connectors can thus be used to daisy-
chain multiple call stations on the same bus. Es. one connector is wired to the alarm system, the other connector is wired to
another call station, and so on.
WARNING: The maximum cable length allowed from the main unit to the farthermost call station is 300 meters.
Once the call station is wired, install back the front panel to the chassis and connect the PTT microphone to its connector.
NOTICE: The connections between the PTT microphone are monitored against cable-cut and cable-short. Please assure that the
microphone is correctly connected to the call station front panel. In case of a fault, refer to the SYSTEM led color and further
details on the Voice Alarm display.
Power supply
The DBEVF call station is powered by the Voice Alarm main unit. By the way, in case of applications with a very long bus cable and
with more than 10 call stations connected to it, it may be necessary to locally power the farthermost call stations. In this case, do
provide an ex24dc 1A power supply the auxiliary power jack.
Dip-Switch settings
Once the call station is wired, it will be necessary to configure the address and set the bus termination. This is achieved through
the Dip-Switch on call station’s electronic board.
The following table indicated the address configuration (ID) of the call station. Switches 1 to 6 need to be configured accordingly.
Please refer also to the Voice Alarm System manual.
