The control outputs allow switching external devices ON or OFF, trigger signals and events,
switch monitor sources, remote control doors, gates or shutters, generate analog signals for the
control of multimedia systems, etc.
A total of 130 control inputs for logic levels, 128 control inputs for analog levels, 16 inputs for
rotary encoders, 127 logic-control outputs, and 128 analog-control outputs are usable.
Clock / Calendar
The ProAnnounce manager DPM 4000 has an integrated quartz-controlled real-time clock which
can be set for automatic operation. The system clock automatically recognizes leap years and, if
in auto mode, automatically switches between daylight saving time and standard time.
The system clock provides the possibility to control up to 40 external slave clocks. For this
purpose, the DPM 4000 employs a special, short-circuit-proof output for pole changing impulses.
Slave clocks are automatically re-synchronized whenever a time difference to the system clock is
detected; like for instance in cases of power outage or when time values were entered manually.
It is possible to activate pre-set functions like break-gong signals, background music, remotely
controlled gates, switch lights ON/OFF, etc., when using system clock and calendar functions
together. All the functions mentioned before can be programmed for specific days; but also
hourly, daily, weekly, monthly, and yearly activation is possible. Up to 500 time-controlled events
can be programmed.
Monitoring
The ProAnnounce manager DPM 4000 embodies a monitor amplifier with headphones/speaker
output. The integrated logic-switching circuit provides the opportunity to listen to the signals of
any internal input and output. Assigning external sound sources to the monitor bus is possible as
well. This additionally allows monitoring amplifier outputs or pre-listen to the contents of external
voice message memories and other audio devices.
The remote control’s wiring already includes all the cabling necessary for the pre-/post-listen
feature when using remote-controlled amplifiers. In addition, when using the DCS 420
ProAnnounce MONITOR MANAGER, additional programming operating flexibility is available.
Macros
Macro is defined as the combination of several commands, functions, and their parameters in an
internal consecutive sequence. For example a gong signal with specific volume and priority
settings has to be transmitted in different calling zones, while simultaneously activating a control
output. In that case the macro consists of the functions “gong” and "control" with the parameters
gong-type, volume setting, priority number, calling zone numbers, and the type and id-number of
the control output.
It is possible to initiate a macro via the special function keys on the paging consoles or to trigger it
via control input. It is also possible to combine a macro with the internal clock or calendar.
The ProAnnounce system provides a number of pre-programmed macros, where only individual
parameters still have to be entered. Additionally, it is possible to combine several macros in a
sequence. Using pre-defined macros and sequences lets you create new, user-specified and
application-related macros, which basically are capable of managing any control function
imaginable. A total of up to 250 user-macros can be programmed.
Interfaces
Besides its control inputs and control outputs, the ProAnnounce system provides additional
interface ports. The connection of paging consoles to the ProAnnounce manager DPM 4000 is
performed via serial RS-485 ports. This allows connecting up to four terminals at a single port.
