SYSTEM DESCRIPTION

3. System Description

This chapter provides an overview of the general configuration of the PROANNOUNCE system and its most important functions. The following block diagram shows a typical PROANNOUNCE system installation including the DPM 4000 central unit, paging stations, audio equipment, amplifiers, power supply unit, relay board assemblies, loudspeaker lines, and control board assemblies for external signals.

figure 3.1 PROANNOUNCE System

3.1 General Overview

The digital PROANNOUNCE manager DPM 4000 represents the central unit of the system. It is used to control and monitor all connected components via several serial interfaces. The chapter Single Device Descriptions contains all necessary information about the DPM 4000 and its available modules.

The kind and amount of connected audio sound sources, amplifiers, and relay board assemblies are extremely variable. This allows configuring the system to basically match any requirement. The system is capable of managing up to 16 paging stations and up to 100 output lines. More than 150 control inputs and outputs are available for controlling and monitoring purposes providing the possibility to generate and manage logic levels and analog levels as well. For detailed information, please refer to the chapter DCS 400 Control System.

Configuration and documentation of a PROANNOUNCE system installation is established through the use of the PROANNOUNCE Designer software – a comfortable graphical user interface that runs on a PC under Windows 95/98/NT. This allows changing the system’s setup at any time to meet new requirements, without the need to alter the actual installation. The PC has to be connected to the system only when loading or changing its configuration. During

PROANNOUNCE System User Handbook 1.1 3-1

SYSTEM DESCRIPTION

normal operation, PC-interaction is not necessary. Anyway, in most cases the permanent connection of a computer bears benefits, like displaying detailed status reports or the printing of protocols. It also offers the possibility for remote diagnosis and remote maintenance via modem.

3.2 Audio Routing

The DPM 4000 employs a digital audio matrix providing 4 inputs and 4 outputs. Additional matrix junctions for the integrated gong and alarm signal generators, the vocal recording/playback unit, and the lock-on of the pilot tone and its evaluation are incorporated. All input signals and internally generated signals can be freely mixed inside the matrix and outputted through the 4 amplifier channels. Routing speaker lines to these amplifier channels is achieved via the relaymatrix, which offers up to four separate audio buses simultaneously, while the DPM 4000 takes over the management of all these signals according to their priority.

Next to connecting paging stations, the audio inputs also serve for the connection of other audio sound sources, like microphones, mixers, CD-players, cassette decks and DAT-recorders, tuners, etc. Several different input modules are available to optimally adjust and match signal levels and connections.

3.3 Volume And Tone Controls / Delays

The PROANNOUNCE system provides individual volume controls for each input, output, and paging station. Even the internal audio sources, like gong/alarm tone generators, voice message playback, and pilot tone generator employ individual level controls, each. Additionally, it is possible to set an attenuation that unanimously affects the inputs. This value determines the degree, by which the input signal is attenuated during the reproduction of messages or other signals with a higher priority setting. This allows to smoothly fade-out and fade-in background music during the transmission of important messages.

Besides, each of the four inputs embodies three fully parametric digital filters allowing for optimal tone control. The filters provide different filter types like Hi-/Lo pass filters, shelving filters, and peak-dip-filters providing the possibility for adjusting the sound within the entire audio transmission range. Factory-preset filter settings for the DPC 4000 Series paging stations are already provided.

Setting volume levels and filter parameters is accomplished via PC during the configuration procedure. Further, it is possible to alter any volume setting during the later operation of the system via special-function keys on the paging stations or through external controls that are connected to analog or digital control inputs.

All four outputs employ digital delays allowing signal delays of up to 330 ms per channel. Natural delays, resulting from loudspeaker positioning which causes time differences in the traveling of sonic events or environmental circumstances related to architectural characteristics of the location, can be equalized without additional effort.

3.4 Signal Generators / Voice Message Memory

The DPM 4000 provides a variety of tone generators for the generation of gong, alarm, and text signals. Signal generation is realized through DSP-algorithms, which are extremely flexible in use, so that they can be adjusted to match nearly any possible application. Factory presets include 6 different gong signals, 18 different alarm signals, plus sine cycle at any frequency. Other than in comparable equipment, the PROANNOUNCE signal generating DSPalgorithms do not take up any extra storage of the voice message memory.

In addition, a voice message recording/playback module providing CD-quality sound is optionally available. With a total recording time of approximately 6 minutes, 25 different messages are being managed. The DPM 4000 provides the possibility to install up to four optional FLASH-memory modules, depending on individual desires or requirements.

3-2 PROANNOUNCE System User Handbook 1.1

SYSTEM DESCRIPTION

3.5 Paging Stations

The DPC 4000 Series paging consoles are mainly meant for transmitting voice messages and calls but also to manually control the PROANNOUNCE system. Available paging station functions are: line/group selection, voice messages, program assignment, launching gong and alarm signals, and reproduction of voice message memory announcements. Additionally, special commands include volume control, monitor selection, preset switching, lighting control, function status indication, etc. Thus, it is possible to configure the paging consoles to serve as operation panels for general control purposes.

If a voice call is being launched into a speaker line that is already busy with other audio transmissions, the caller gets a busy-sign, i. e. the BUSY-LED blinks. In case the calling terminal has a higher priority it will interrupt any messages from other paging stations or audio signals with lower priority levels. Interruption does not take place uncontrolled anymore. Before actually interrupting a transmission, the blinking LED indicates that a line or group is busy when selecting a destination, leaving the choice to the operator, whether he/she immediately wants to interrupt or wait upon the conclusion of the momentary reproduced program.

3.6 Control Inputs And Outputs

By using the control inputs, it is possible to link the PROANNOUNCE system to fire alert systems, burglary alert systems, or to a central operating desk. It is also possible to connect external switches, breakers, rotary controls or rotary encoders, respectively to query control outputs of external units (power supplies, power amplifiers, …).

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.

3.7 Clock / Calendar

The PROANNOUNCE manager DPM 4000 has an integrated quartz-controlled real-time clock which can be set for radio-controlled DCF 77 operation using the optional antenna (DCF 77 tuner NRS 90193). The system clock automatically recognizes leap years and, if in DCF 77 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 resynchronized 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 function 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 timecontrolled events can be programmed.

3.8 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.

When using the DCS 420 PROANNOUNCE MONITOR MANAGER, easy programming and operating is available. See also chapter 5.4.7

PROANNOUNCE System User Handbook 1.1 3-3

SYSTEM DESCRIPTION

3.9 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 idnumber 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.

3.10 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. Power amplifiers and the DCS 400 controller are connected to another independent RS-485 port, which allows direct management of up to 64 power amplifiers and 8 DCS 401.

Connecting a PC is established via serial RS-232 port on the rear panel of the DPM 4000. It is not necessary for the PC to be permanently connected to the DPM 4000.

An additional RS 485-interface offers the possibility to operate several DPM 4000 in a network.

3.11 Safety Standards

The PROANNOUNCE system complies with all applicable requirements of the IEC 849 standard – electro acoustics emergency alert PA-systems. The digital PROANNOUNCE manager DPM 4000 guards and monitors its entire internal functions. All connected paging stations and power amplifiers, including the wiring, are monitored via polling and pilot tone functions. Using the remote control units in the power amplifiers, it is also possible to monitor the loudspeaker lines. Of course, the PROANNOUNCE system is also prepared for operation with emergency power supply. In case of a power outage, the DPM 4000 takes over the entire power management; i. e. all internal and external power consuming components are switched to stand-by mode. Only when necessary, they are turned on again. This minimizes the total power consumption efficiently and guarantees maximum operational reliability when the system is operated from a battery power source.

Fault messages are being displayed in plain text on the paging console displays and a floating contact is provided for collective fault messages. An automatic protocol facility of the system's individual state of operation is optionally possible. This protocol is stored in the DPM 4000's internal memory. If necessary, it can be displayed on the screen of a connected computer or printed out via a printer.

The radio control signal is received. The system clock is synchronized to the DCF 77 signal.

The radio control signal is present and the system clock is being synchronized. This procedure can take up to 2 minutes. After synchronization is complete, the DCF 77 LED light continuously.

The radio control signal is detected but its reception is jammed. Readjusting the DCF 77 antenna or choosing a location with improved reception is recommended.

2. LED READY

This LED indicates the operation mode of the PROANNOUNCE System. After switching the power on, the READY LED blinks while the system boots. Depending on the complexity of the installation blinking can take several seconds. After successful initialization, the LED lights, signaling that the system is ready for operation. Whenever erroneous operation – either in the DPM 4000 or in one of the connected components – is detected, the LED goes out indicating that a system error occurred. When the system power is OFF, the READY LED is OFF as well.

3. LED POWER

This LED lights as soon as a power source (24 V =, power supply or battery) is connected to the DPM 4000. The LED does not light when the DPM 4000's power supply is disconnected, switched off or fails.

4. LED FAULT

This LED lights during a reset or when an internal watchdog error is being detected within the DPM 4000. It also indicates erroneous operation of external system components (power amplifiers, paging stations, relay boards, ...). The LED is connected to the READY relay on the rear of the appliance, which allows remote indication of system errors.

The following module ports and connections are located on the rear panel of the DPM 4000:

1. DC INPUT 24V ==

The DPM 4000's power supply source has to be connected here; a 24 VDC power supply or a PROANNOUNCE system battery module using insulated AMP flat-connector plugs 6.3 x 0.8 mm. The DPM 4000 is protected against polarization mismatch and all positive and negative conductors within the device are fuse-protected. The fuses are located inside the enclosure on the printed board assembly 80430. The connection cables have to be 1,5 mm diameter at least. With this diameter the cable length of a single path should not exceed 4.0 m (max. drop in voltage <1V).

CAUTION: Using the DPM 4000 is only permissible with batteries that are not grounded or provide a grounded

negative pole. Operation with grounded positive pole is not admissible.

5.1.5 2-Channel Paging Station Module (NRS 90215)

This 2-channel audio input module is meant for the connection of DPC 4000 Series paging consoles. Each of the two input channels provide RJ-45 sockets allowing the connection of up to 4 paging stations plus paging station extensions per input. The microphone terminals are interconnected via 6-conductor parallel cables. The module can be installed in slot 1 and slot 2.

Next to the electronically balanced audio input, each input connector provides a serial RS-485 interface port and the power supply connection for the paging stations (see also: pin-assignment of the RJ-45 connector). The paging stations' power supply employs an electronic, programmable fuse, through which the maximum output current can be matched to meet actual system accommodations. This prevents the entire installation from malfunction, in case of short-circuit occurring in a single paging station only.

Input channels can be switched separately onto the monitor bus and you can monitor the audio signal via headphones or loudspeaker, either which is connected to the monitor output. Automatic pilot tone surveillance of the entire input stage is integrated as well. If necessary, retrofitting the audio inputs with transformers is possible.

Internal Settings:

1. MIC / LINE switching and sensitivity setting for the MIC / LINE inputs

The MIC / LINE input's internal PAD-switches (IN A: S1, IN B: S2) allow switching the channels' sensitivity between microphone and line level (30 dB). The two GAIN-controls on the module's front panel are provided to precisely adjust the input sensitivity (range 40 dB).

In addition, two MIC/LINE jumpers (IN A: JP1, pins 5-6, IN B: JP2, pins 5-6) are located on the printed board assembly allowing the correct configuration of the inputs. When changing a MIC/LINE switch it is important to change the related jumper correspondingly (open = LINE, closed = MIC).

When shipped, the factory presets are: switches S1 and S2 set to LINE and jumpers JP1 and JP2 are open.

2. Phantom Power

By closing the jumpers JP1, pins 1-2 and pins 3-4 (IN A) respectively JP2, pins 1-2 and pins 3-4 (IN B), it is possible to (separately) engage 24 V phantom power when a microphone is connected to the corresponding input. When shipped, jumpers are set to “open” (no phantom power).

3. Compressor / Limiter

The MIC / LINE input channels embody compressor / limiter circuits, which can be incorporated in the signal paths via the jumpers JP3 for IN A and JP4 for IN B (position “COMP”), if needed. Normally, the compressors / limiters should be used to eliminate the risks of overdrive and clipping, when directly connecting microphones. When shipped, the jumpers are set to “LIN”.

Retrofitting Input Transformers:

In case galvanic separation of the audio signals is necessary, the module can be retrofitted with two input transformers. This is accomplished by using an extension kit NRS 90233 per input channel.

When retrofitting input transformers, please proceed as follows:

1. Disconnect the DPM 4000 from the mains power supply.

2. Loosen the two locking screws and carefully slide the module out of the slot..

3. Remove the two resistors of the correspondent input channel (IN A: R2 / R3, IN B: R10 / R11).

4. Solder the transformer for IN A in position T1 and for IN B in position T2 onto the printed board assembly.

5. Re-insert the module into the slot and carefully push it into the DPM 4000 until it firmly locks in place.

6. Fix the module in place using the two locking screws and reconnect the power supply.

5.1.9 MIC/LINE + Paging Station Module (NRS 90234)

This 2-channel audio input module is meant for the connection of DPC 4000 Series paging stations and other external audio sources. The RJ-45 socket of channel A allows the connection of up to 4 microphone terminals plus paging station extensions. The MIC / LINE input of channel B is furnished through an XLRF-type connector allowing the connection of microphones, mixers and other audio signal sources. The module can be installed into slot 1 and slot 2.

Next to the electronically balanced audio input, the DPC 4000 input connector provides a serial RS-485 interface and the power supply for the connected paging consoles (see also pin-assignment of the RJ-45 connector). The paging stations' power supply employs an electronic, programmable fuse, through which the maximum output current can be matched to meet actual system accommodations.

The MIC / LINE input employs an internal switch (PAD) providing 30 dB of attenuation. The GAIN-control located on the appliance's rear panel offers additional control in a range of 40 dB. The input is electronically balanced and prepared for retrofitting a transformer. Phantom power can be switched via jumper. If necessary, a compressor / limiter circuit can be incorporated in the audio path.

Note:

When connecting several paging consoles to a single input, please keep in mind that line interruption or short-circuit can cause malfunction of several or even all paging stations of that specific line. In emergency alert installation, connecting security-related consoles to individual inputs is therefore of major importance.

Retrofitting Input Transformers:

Retrofitting two input transformers onto the module is possible for the case that galvanic separation of the audio signals is needed. For the DPC 4000 input a NRS 90208 extension is needed, which consists of an audio transformer and an insulation plate. For the MIC/LINE input a NRS 90233 extension is needed.

When retrofitting input transformers, please proceed as follows:

1. Disconnect the DPM 4000 from the mains power supply.

2. Loosen the two locking screws and carefully slide the module out of its slot.

3. Remove the two resistors of the corresponding input channel (IN A: R8 / R9, IN B: R3 / R4).

4. With the DPC 4000 input (IN A), you have to place the insulation plate between the transformer and the printed board assembly. Then solder the transformer in position T2; with the MIC/LINE input (IN B), you have to solder the transformer in position T1.

5. Re-insert the module into the slot and carefully push it into the DPM 4000 until it firmly locks in place.

6. Fix the module in place using the two locking screws and reconnect the power supply.

5.1.10 2-Channel LINE Output Module (NRS 90218)

The output module is meant for the connection of power amplifiers with an input sensitivity of 0 dB or +6 dB. Two XLRM-type connectors allow the connection of up to 20 power amplifiers each. The audio signal is electronically balanced; if necessary, transformers can be retrofitted. The module can be installed in slot 3 or slot 4.

The output channels can be switched separately to the monitor bus and you can listen to the signal via headphones or loudspeaker, either which is connected to the monitor output. Automatic pilot tone surveillance of the two output channels is also integrated. The jumpers for adjusting the output voltage to 0 dB or +6 dB are located on the printed board assembly. At the same time you have to alter the jumper setting of the monitor signal correspondingly.

The output module employs integrated output relays that prevent switching noise from being heard. When switching the system on, the output signal is put through after the system is been initialized (power-on delay); the contacts are immediately interrupted when switching the power off.

5.1.11 8 I/O Control Module (NRS 90219)

This control module provides 8 floating control inputs and 7 floating logic level outputs (0 V, 24 V). An additional output provides pole change impulses for controlling slave system clocks. Contact is established via 4 x RJ-45 sockets providing 8 contacts each. The module can be installed in slot 5.

The slave clock output (NU, OUT 1) is short-circuit proof; up to approximately 40 slave clocks can be connected. Please make sure to connect all slave clocks according to their correct polarity.

The control outputs (OUT 2 - 8) are capable of switching voltages of either polarity and up to a maximum current of 1 A.

The control inputs (IN 1 - 8) are capable of handling voltages of either polarity between -31 V and +31 V; for voltages between 0 and 5 V the inputs are not active (low), for voltages between 10 V and 31 V the inputs are active (high). The control inputs can ignite switching functions or macros either during a change of state or in any stationary state. This offers the possibility to monitor line idling currents (e. g. in fire alert system installations).

Note:

The opto-coupler inputs are primarily meant to prevent noise loops that can result from dropping voltages in long distance cabling. They are not suitable for separating networks from each other. Therefore, only floating sources should be connected.

5.2 PROANNOUNCE – DPC 4000 Paging Consoles

5.2.1 System Overview

The PROANNOUNCE system includes 5 different models of DPC 4000 Series paging stations and one paging station extension. All microphone terminals employ gooseneck microphones, 6 or 8 function keys and a covered alarm key. An additional alarm key and a key-locked switch can be retrofitted. The paging stations are available with 10, 20, 30, or 50 selection keys. All models also employ LC-displays (2 lines with 16 characters each).

The following list provides you with an overview of available paging station models:

DPC 4510 8 function keys + 10 selection keys + alarm key

All paging consoles include the following common features:

All paging consoles are processor-controlled and extensive monitoring functions are provided. The watchdog function monitors the processor system while a switchable pilot tone generator monitors the audio section. Additionally, the internal supply voltage is constantly measured. When it falls below a critical threshold an alert message is being displayed. The line surveillance function recognizes any line-interruption and/or short-circuits in the audio and RS-485 control cabling. Upon the detection of failure a corresponding message is displayed.

The PROANNOUNCE Designer software allows comfortably configuring the paging stations. Its graphic, dialogue-oriented user interface offers effortless assign of key functions, priorities, options, and many other paging station functions.

is important to keep the fact in mind that in case of line interruption and short-circuit several microphone terminals may fail. Despite, one input allows only launching one message at a time. All other connected paging stations are presented with a busy-message. If these restrictions are not acceptable, every microphone terminal – or at least all directing stations and other important paging stations – should have its own input at the central unit.

The LED’s indicate the momentary selection status (also refer to the paragraph “indications”). It is also possible to assign special functions or no function at all (no function assigned) to the selection keys. Assigning functions is performed during the configuration procedure via PC.

Note:

When shipped, these keys are factory pre-set as area selection keys, where key 1 –

area 1, key 2 – area 2, ..., key n – area n.

7 8

2 ALL key and LED

The ALL key allows the selection of all programmed areas at once for transmitting messages, gong or alarm signals, vocal messages, or to assign programs. One time pressing selects all areas. The corresponding LED’s and the ALL LED are lit. Subsequent pressing cancels the selection.

3 CANCEL key

This key offers different functions, depending on the actually selected operation mode, e.g. cancel calling pattern or cancel program-assignment. Which function is carried out at times is explained in detail in the paragraph OPERATION.

4 GONG key (ESC) and LED

Pressing this key starts the transmission of a gong signal in the pre-selected areas or groups. The GONG LED lights or blinks during the transmission of a gong signal. What kind of gong signal is being transmitted is defined during the configuration procedure. Pressing the STOP key cancels the reproduction of the gong signal.

While in setup-mode, this key is used to return to ‘normal’ user mode (ESCAPE = leaving setup-mode).

5 TEXT key (Ú) and LED

Pressing the TEXT key starts a prerecorded message (optional voice reproduction), which is transmitted into pre-selected areas or groups. The TEXT LED lights or blinks during the transmission of a prerecorded message. The desired text message is selected during the configuration procedure. Pressing the STOP key cancels the reproduction of a text message.

While in setup-mode, pressing the TEXT key decreases the selected parameter value (parameter entry).

6 TALK key and BUSY-LED

This key activates a message for pre-selected areas or groups. The BUSY LED lights during transmission. The TALK key has to be pressed until the end of a message. The BUSY LED blinks when one or several areas are busy or when an event with higher priority setting interrupts the output message (see paragraph indications). In the latter, it is necessary to repeat the message.

7 ON key (<) and LED

This key turns the system’s power on or off. Turning the power on can take several seconds. The ON LED blinks while the system boots. The ON LED lights steadily when the system is operational. To prevent inadvertent erroneous operation pressing the key for at least 1 second is necessary when turning the power off. It is also possible to prohibit the operation of the ON key during the configuration procedure.

In setup-mode this key is used to select the previous parameter (parameter selection).

8 STOP key (Ù)

Pressing the STOP key cancels an output alarm signal or text message. Terminating an alarm signal is also possible by subsequently pressing the ALARM key. Only events that were triggered from a specific paging console can be stopped from the exact terminal with the exception of the directing station. This terminal allows canceling all signals.

While in setup-mode, this key increases the selected parameter value (parameter entry).

9 PROGRAM key (>) and LED

Pressing the PROGRAM key selects the program assign mode. The selection keys are used in this mode to assign a program (background music) to the desired areas or groups. The PROGRAM LED lights while being in the program assign mode. In this case the selection LED’s indicate the areas / groups the program is being transmitted into.

Keeping this key pressed and simultaneously pressing the STOP key selects the setup-mode and the PROGRAM LED starts blinking. Now you can alter preferences or make other changes as described in the chapter 5.2.7 Paging Station Configuration In Setup Mode.

When in setup-mode, this key is used to select the following parameter (parameter selection).

10 ALARM key and Indicator

Pressing the ALARM key starts an alarm signal that is transmitted into all areas. The alarm indicator lights when launching an alarm. Pressing the STOP key or subsequently pressing the ALARM key terminates the alarm signal. What kind of alarm signal is being transmitted is defined during the configuration procedure of the PROANNOUNCE system.

11 Optional Key-Slots

These slots allow retrofitting an additional covered key and a key-locked switch. The front panel is already prepared for the installation of two 18 mm pushbuttons / switches. You only have to cut suitable holes into the front panel foil. Internal fittings and cables are also already prepared. The newly installed switches’ functions are assigned during the configuration procedure via PC; e.g.: second alarm-pushbutton for transmitting an alarm signal into specific areas (selective alarm), or assigning the system ON / OFF function to the key-locked switch.

Detailed information and installation instructions are provided in the chapter 5.2.13 Optionally Available Accessories.

12 Microphone

After pressing the TALK button and after the BUSY LED lights making announcements in pre-selected areas or groups is possible using the integrated gooseneck microphone. The optimum distance from the microphone is approximately 20 to 35 cm. The microphone pre-amplifier embodies a limiter to control signal peaks and protect the system against overdrive.

The extension socket (EXT) allows connecting a second microphone with TALK button. Assigning the function (area, group) of the external microphone is performed during the configuration via PC.

13 Display

Depending on the actual operational status of the system, the LC-display with 2 lines of 16 characters each, shows information on time, operation mode, user notes, setting up, fault messages including precise device / module specification, etc.

5.2.4 Connections

1 LAN socket

This is the interface for connecting DPC 4000 Series paging stations to the PROANNOUNCE system. The 8pole RJ-45 connector provides power supply, control interface RS-485, and audio connections. The microphone terminal has to be connected to a corresponding RJ-45 wall outlet using the supplied connection cord (3 m). The following figure shows the pin-assignment of LAN socket and RJ-45 network cable. Please also pay attention to chapter 5.2.14 Cable Lengths.

5.2.5 Key-Labeling

Labeling the keys of paging consoles is done using label-strips, which can be slid in from the side. The label-strips for the 6 or 8 function keys are slid in from the right while the selection key strips – for 10, 20, 30, or 50 selection keys – are inserted from left. Therefore, you have to detach the correspondent side panel (2 screws) and insert the labeled strip into the gap between the front panel and the front panel foil.

The most convenient way of printing the labels is to utilize the word processing software MS-WORD. A suitable MS-WORD template file is supplied. Please note that with different printer models margin-settings may vary. Please adjust the layout form according to the individual specifications of your printer model.

5.2.6 Operation

This chapter explains all functions that are used during general operation.

Selective Call

The user can launch calls or announcements into freely selectable areas or groups.

Pressing a single or several selection keys defines areas or groups where a call is launched into – corresponding LED’s will light. By pressing the key of an already pre-selected line once again deactivates that line and the corresponding LED goes out.

After making a selection, pressing the TALK-button ignites the call. Prior hereto, the BUSY LED allows checking whether all lines and the paging station input are actually free. If single lines or the terminal input are busy with lower priority transmissions, the BUSY LED will blink slowly. Whilst making an announcement is possible, this will interrupt any other transmitted event. If single lines or the terminal input are busy with higher priority signals, the BUSY LED will vastly blink and the calling attempt is ignored (also refer to the description of indications).

The BUSY LED lights during the transmission of an announcement. The TALK button has to be pressed during the whole message. Until the user makes any changes, the defined selection stays memorized, even after releasing the TALK button. Pressing the CANCEL key de-selects the entire selection.

Additionally and in case of a pre-gong signal has previously been programmed, the GONG LED will light during the transmission of the pre-gong signal.

Collective Call

The announcement is launched into all areas of the entire installation.

The procedure is similar to making a selective call. First, all areas of the installation are selected by pressing the ALL key. Pressing the TALK button activates the collective call. During the transmission of a call, all area and/or group LED’s as well as the ALL LED will light (also refer to the paragraph “indications”). The TALK button has to be pressed down until the end of the announcement. BUSY LED indication and the behavior of the pre-gong signal are equivalent to the selective call.

Direct Call

Principally, assigning a direct call to any selection key (area key, group key, ALL key) is possible via PC during the configuration procedure. This allows making an announcement directly by pressing the desired selection key – without need to press the TALK key. For direct calls the BUSY LED also signals the status of correspondent areas (free, busy with lower priority signal, busy with higher priority signal; see “indications”). When shipped, there is no factory pre-set direct call programmed.

Gong (Chime) Signal

By factory the Gong key is programmed as a general call

A gong signal can also be transmitted into any selectable area or group of the entire installation (if programmed).

First, the desired areas / groups have to be selected; either by use of the selection keys (selective gong) or with the ALL key (general gong). Pressing the GONG key releases the gong signal. While the gong signal is being transmitted, the GONG LED lights continuously or blinks (also refer to indications). The gong’s priority can be set to 6 or 7. Therefore it has priority over announcements from any paging station, except for the directing terminal (priority 10).

Pressing the STOP key cancels the transmission of a gong signal.

During setup mode this key is used to go back to the normal operating mode (escape).

PROANNOUNCE System User Handbook 1.1

5-35

DEVICE DESCRIPTIONS

Text Message

A text message recorded via the optional message module or using an external recording/playback device can be transmitted into any selectable area or group of the entire installation.

First, the desired areas / groups have to be selected; either by use of the selection keys or via the ALL key. Pressing the TEXT key starts the reproduction of a prerecorded message that had been assigned during configuration. While the text message is being transmitted, the TEXT LED lights steadily or blinks (also refer to indications). The text message priority can be set to values between 2 and 8.

Pressing the STOP key cancels the transmission of a text message.

General Alarm

A general alarm signal is always transmitted to all lines of the entire installation.

Pressing the covered ALARM key launches the integrated alarm. The key lights during the transmission of the alarm signal. The priority of the alarm can be set between 7 and 9. Therefore it has priority over any announcement or other event, except for those that were ignited from the directing paging station (priority 10).

Pressing the STOP key or subsequently pressing the ALARM key cancels the alarm.

Selective Alarm

When a paging station is equipped with a second ALARM key providing the option for selective alarms, it is possible to transmit alarm signals into selected lines.

Similar to the procedure for making a selective call you first have to select areas or groups to which the alarm signal shall be transmitted. Afterwards, pressing the covered ALARM key starts the selective alarm. The key lights during the transmission of an alarm. Already now, you are able to enter the lines for the following alarm.

Pressing the STOP key or subsequently pressing the ALARM key cancels the alarm.

When shipped, there is no factory pre-set selective alarm pre-programmed.

Note:

The launch of an alarm does not depend on a paging console’s priority setting it had been

activated from. Launching an alarm is possible from any microphone terminal at any time, even when the system is in stand-by mode. A running alarm is optically and occasionally also acoustically indicated at every paging station.

Canceling Signals

Pressing the STOP key cancels alarms, gong signals and text message transmissions. Events can only be terminated at the paging station they were launched from with the exception of the directing terminal (paging console with the highest priority possible 10). Through the directing station it is possible to cancel any signal in progress.

5-36 PROANNOUNCE System User Handbook 1.1

DEVICE DESCRIPTIONS

System ON / OFF

The ON key switches a PROANNOUNCE system ON or OFF. Mostly, it is not intended that any paging station be provided with the possibility to do so. Thus, this function can be programmed via PC-configuration.

When the system is in stand-by mode, the ON LED is off. Pressing the ON key turns the PROANNOUNCE system’s power on which can take up to 10 seconds, while the ON LED is blinking. Once the system is ready for operation, the ON LED lights continuously (which also applies for all paging stations of the entire installation).

To switch the system OFF, you have to press the ON key for approximately 1 second. This is to prevent inadvertently turning off the system.

Pressing an ALARM key or igniting an alarm sequence at external terminals automatically switches the PROANNOUNCE system’s power on and boots the system.

Program Assignment

Activating this feature allows the assignment of programs to individual areas and groups of the entire installation during the PC-configuration procedure.

First, by pressing the PROGRAM key, the paging station has to be set to program-assign mode. Pressing a single or several selection keys assigns the outputted program (background music) to the selected areas and groups. The corresponding LED’s are lit. Program transmission has always the lowest priority (1). The signal level is determined during system configuration. The assignment stays memorized until the selection keys are pressed again. Pressing the CANCEL key erases the entire assignment-pattern.

Subsequently pressing the PROGRAM key or any other function key cancels program-assign mode. It is also automatically canceled after approximately 15 seconds.

In single-program configuration the music reproduction into all areas of the installation is attenuated for the time of an announcement. In double-program configuration parallel transmission of a background music program into rooms that are not part of an actual announcement selection is possible as well. If every line incorporates its own LF-output and separate power amplifiers, mixing announcements and background programs is possible in any way.

Special Functions

Generally, assigning a function to each selection key is possible. This allows utilizing a paging station to control the lighting, door openers, blinds, etc.; even controlling volume settings is possible through the use of the UP / DOWN keys.

When shipped, there are no special functions assigned.

5.2.7 Paging Console Configuration In Setup Mode

Configuring paging consoles is preferably performed on the central unit via computer and using the PROANNOUNCE Designer software. This represents the most convenient way without any limitation, while a paging terminal itself offers only limited programming ability.

Several key functions differ between setup-mode and operation mode. Alternate functions are marked on the right top corner of the individual key area.

Pressing PROGRAM key and STOP key simultaneously for at least 1 second – the PROGRAM LED starts blinking – engages a paging station’s setup-mode.

Note:

Paging stations where program-assignment has been activated indicate the program

assignment-pattern for a short period of time.

Using the ‘<‘ and ‘>‘ keys lets you step through the setup menu items in forward and backward direction (parameter selection). Parameter number and name are shown on the display.

The following table shows an overview of parameters and their meaning:

Parameter

6 Date / Time

7 LCD contrast

The ‘Ù‘ and ‘Ú‘ keys activate / deactivate corresponding parameters or increment / decrement according parameter values. For directly entering numerical parameters, use selection keys 1 to 10, where the 10-key represents the “0”.

Pressing the ESC key returns to ‘normal’ operation. The setup-mode is also automatically canceled when for approximately 15 seconds no entry or change has been made. All parameters are automatically stored.

1 Address

Paging consoles accept the assignment of addresses between 1 and 16. The setting is generally performed using the numerical keys 1 to 10, where the 10-key represents the “0”. For paging stations without selection keys, the address has to be set using the ‘Ù‘ und ‘Ú‘ keys.

DEVICE DESCRIPTIONS

2 Password

(does not apply to paging consoles without selection keys)

3 or 4-digit passwords provide protection for paging consoles against unauthorized operation. Password protection can be established in two levels. The first level is the ‘normal’ user-level. In case this level is password-protected, the paging station cannot be operated except for launching an alarm. The second level is the setup-level. If this level is password-protected, the setup-mode is not accessible while unlimited ‘normal’ operation is possible.

Level 1 and 2 passwords are assigned and transferred to the individual paging stations during the PCconfiguration procedure. As factory preset the level 1 password is set to ‘111’ and the level 2 password is ‘2222’; level 2 (setup-mode) is password-protected (factory pre-set).

To prevent a paging station from unwanted access, you have to enter setup-mode and select parameter 2 “password”. Depending on which function of the paging console you want to protect, by using the selection keys you have to enter either the 3-digit level 1 password or the 4-digit level 2 password. Protection is now activated and operation (1st level) and/or programming (2nd level) are not possible anymore. The blinking PROGRAM LED indicates this status.

The protection is canceled by re-entering the correct password while being in setup-mode.

3 Pre-Gong Signal

It is possible to program a pre-gong signal that is heard before an announcement. The pre-gong signal is transmitted into the selected areas when pressing the TALK-button. You can begin with your announcement during the transmission of the pre-gong signal; you can talk “into” the pre-gong.

Using the arrow keys (<>) first select parameter 3. Now, you can ignite the pre-gong signal with the ‘Ù‘ key or cancel it by using the ‘Ú‘ key. The pre-gong function can also be activated or deactivated during PCconfiguration.

4 Buzzer

The integrated buzzer can be programmed as acoustic alert signal. During failure, malfunction, or as general alert a buzzing sound is heard. When an alarm has been launched, the buzzing can be heard for the whole period of the alarm.

First, select parameter 4 using the arrow keys (<>). Now, you can activate the buzzer by pressing the ‘Ù‘ key. Pressing the ‘Ú‘ key deactivates the buzzer. The buzzer function can also be activated during PCconfiguration.

5 Compressor

The paging stations’ microphone pre-amplifier incorporates compressor / limiter circuitry. While the limiter is constantly activated, the compressor can be switched ON or OFF. When the compressor is engaged, lowlevel signals are amplified to a higher degree, which results in constant talking levels although the distance between the announcer and the microphone varies. Besides, you have to keep in mind that also environmental noise is amplified. Thus, on-site testing with and without compressor will reveal which results in the better performance.

First, by using the arrow keys (<>), select parameter 5. Pressing the ‘Ù‘ key activates the compressor. Pressing the ‘Ú‘ key deactivates the compressor. It is also possible to activate the compressor during the PCconfiguration procedure.

6 Time / Date

(does not apply to paging consoles without selection keys)

The connected paging stations allow setting the date and time of the PROANNOUNCE system.

First, by using the arrow keys (<>), select parameter 6. Using the selection keys 1 to 10 – with the 10-key representing the “0” – you can enter the correct time. Date and time are indicated in the following format: tt.mm.yy hh:mm. They have to be entered in that sequence

7 LCD-Contrast

Paging consoles with display allow the user to individually adjust LCD-contrast and viewing angle. This allows optimum legibility from the user’s location.

First, by using the arrow keys (<>), select parameter 7. Now, you can adjust the LCD-contrast via the ‘Ù‘ or ‘Ú‘ keys.

5.2.9 Priorities

The PROANNOUNCE system allows setting 10 priority levels (highest priority = 10, lowest priority = 1) that include announcements, as well as alarm and gong signals, and vocal message reproduction. A higher prioritized event principally interrupts any other event with a lower priority setting. For events with equal priority the earlier launched signal is continued; has priority over the latter.

These priorities can be freely assigned to any ‘normal’ paging console. A pre-gong signal has the priority of the launching microphone terminal.

5.2.10 DPC 4350 Paging Station Extension

The DPC 4350 paging station extension provides selection keys only. It is employed whenever a higher amount than 50 lines need to be accessed or when an installation’s requirement of group and special function keys exceeds the existing amount of selection keys. The DPC 4350 can be easily combined with any other paging station model. The following list shows the amounts of maximally accessible lines for various combinations:

Combination Maximum amount of lines

DPC 4106 + DPC 4350 50

DPC 4510 + DPC 4350 60

DPC 4520 + DPC 4350 70

DPC 4530 + DPC 4350 80

DPC 4550 + DPC 4350 100

The extension unit is directly connected to the extension interface of the main paging station using the supplied 8pole RJ-45 cable and plugging it into the EXT-socket. A single paging station then consists of two devices that report to a common address. Therefore the central unit recognizes them as one single an increased amount of selection keys. Also from the viewpoint of the user the two devices act as only one paging station; i.e. the selection keys of the main and the slave paging station provide equal access to their assigned areas, groups and special functions.

Note:

During the configuration of the system using the PROANNOUNCE Designer software, it is

important that the main paging station’s EXT-socket is configured for the connection of a DPC 4350 extension.

DEVICE DESCRIPTIONS

5.3.2 Instructions For Using Remote-Power Amps:

1. Each power amplifier has to be set to the exact address as it is specified in the PROANNOUNCE Designer software (A=low value part, B=high value part). Address setting is performed using hexadecimal code.

2. An RS-485 connection needs to be established between the DPM 4000 (remote socket) and maximally eight DCS 401, and maximally 64 amplifiers (DPA 4411 counts as a single unit). The RS-485 bus may not exceed a maximum length of 1,000m and must follow a line-structure with stub cables being as short as possible. When including more than 30 amplifiers, both ends of the bus have to be terminated with 120 ohms resistors. This bus is also used for monitor signal transmission.

3. Connect the amplifier(s) to an operation voltage source.

4. Perform a Netscan procedure via the PROANNOUNCE Designer software. In ‘normal’ operation the statusLED’s on the rear panel of the amplifiers have to light periodically, depending on the number of participants on the bus (communication with the DPM 4000).

5. Within the communication window of the PROANNOUNCE Designer software checking which addresses are registered as participants is possible using the command “/AMP/AVLBL ?”.

6. Once a participant on the bus had been disconnected from the DPM 4000 for a short term (e.g. because the RS-485 line had temporarily been disconnected), it is included again in the query sequence after 10 sec.

5.4 DCS 400 Control System

5.4.1 Characteristics

DCS 400 Series modules increase the PROANNOUNCE system's control functionality in miscellaneous ways. These printed board assemblies in the Europe standard format are usually inserted at the rear of a PA-system rack-shelf or installed in suitable distribution boxes. The DCS 400 system consists of five different modules and additional extensions:

· DCS 401 control module for controlling relays, logic inputs, analog inputs and outputs, and rotary encoders

· DCS 408 relay module with 5 line relays for 100 V systems

· DCS 409 relay module with 5 NF or control relays

· DCS 412 logic input module with 12 floating, bi-polar inputs that are linked via opto-couplers

· DCS 416 analog I/O module offering 8 inputs and 8 outputs for 0 V DC to 10 V DC

· DCS 420 monitor module with 7-segment display, meter instrument and monitor loudspeaker

· NRS 90240 rotary encoder

A PROANNOUNCE installation allows integrating a maximum of up to 8 DCS 401 control modules. A single control module can host up to 12 relay boards of the types DCS 408 / DCS 409 in any sequence. Besides, it is possible to connect up to 5 logic input modules, 2 analog I/O modules, and 2 rotary encoders.

The PROANNOUNCE operating system defines the total amount of supported control inputs and outputs. The PROANNOUNCE system can manage following amounts of different cards:

· Control module DCS 401 max. 8 boards = 16 rotary encoders

· Relays modules DCS 408 / DCS 409 max. 48 boards = 240 relays

· Logic input module DCS 412 max. 10 boards = 120 logic inputs

· Analog I/O module DCS 416 max. 8 boards = 128 analog inputs / outputs

· Monitor module max. 1 per DCS 401

Note: The power supply of individual boards can be provided either via RJ-45 connection (DCS 401), flat-

wire cables (DCS 408, DCS 409, DCS 412, DCS 416) or via 2 binding posts (±24 V) that are located on each board. The current that runs through the RJ-45 connection or the flat-wire cables has not to exceed 1 A max. The current for modules that are connected to the DCS 401 via flatwire cables may not exceed 700 mA max. The connectors CN7, CN8, CN9 share an electronic fuse. For higher currents, it is important that under all circumstances the binding posts are used instead. When cascading several modules, it is necessary to provide the power supply anew via binding post connection. Directly cascading up to 7 or 10 modules is admissible while taking power consumption features of the different types of incorporated modules into consideration. All modules need to be fed from a single power source! Data inter-exchange amongst modules has to be established via flat-wire cabling.

CAUTION: For safety reasons, DCS 400 modules may only be installed in rack-shelf systems or enclosures

that are locked and may only be opened by means of a tool (e.g. screw-driver, special key, etc.).

When installing modules, make sure to follow all requirements of the EN60065:1993 regulation.

Obeying the regulations for interference-emission (EN55022, class B) and interference-stability

(EN50082-2), DCS 400 module printed board assemblies need to be grounded at their fixing points (e.g. using a metal bolt).

A single DCS 401 control module can host a maximum of 12 relay modules DCS 408 / DCS 409, five logic input modules DCS 412, two analog input / output modules DCS 416, and two rotary encoders. Relay modules are connected to the CN7 connector using the supplied flat-wire cable. DCS 408 or DCS 409 boards can be installed in any order. Logic input modules are connected to the CN8 connector while analog I/O modules have to be connected to CN9. The CN12 connector allows the connection of two rotary encoders.

Features

· Two RJ-45 connectors for connecting the DPM 4000 and for cascading several DCS 401 control modules

· Galvanic separation of the RS-485 interface port

· One connector each for relay modules, logic input modules and analog signal modules

6.1 PROANNOUNCE Hardware Configuration

6.1.1 DCS 400

When configuring and initially operating the DCS 400 system, please proceed as follows:

1. Cabling

➨ Use the supplied flat-wire cable for connecting the relay modules DCS 408, DCS 409 in the desired order to the

control module DCS 401. Mixed installation of relay modules is possible; numbering the relays is type-specific and has to be performed according to their sequence.

example:

Sequence Module Line relay No. Control relay No.

1 DCS 408 1 - 5

2 DCS 408 6 - 10

3 DCS 409 1 - 5

4 DCS 408 11 - 15

5 DCS 409 6 - 10

6 DCS 408 16 - 20

... ... ... ...

➨ Use the supplied flat-wire cable for connecting the logic input module DCS 412 to the control module DCS 401.

Numbering the logic inputs has to be performed according to their sequence.

example:

Sequence Module Logic input No.

1 DCS 412 1 - 12

2 DCS 412 13 - 24

3 DCS 412 25 - 36

... ... ...

➨ Use the supplied flat-wire cable for connecting the analog input / output modules DCS 416 to the control module

DCS 401. Numbering the analog inputs and outputs has to be performed according to their sequence.

example:

Sequence Module Analog input No. Analog output No.

1 DCS 416 1 - 8 1 - 8

2 DCS 416 9 - 16 9 - 16

➨ Connect the control module DCS 401 via RJ-45 cable to the REMOTE CONTROL socket on the DPM 4000.

PROANNOUNCE System User Handbook 1.1

6-1

APPENDIX

2. Voltage Supply

➨ Insert bridges serve to select the voltage supply connector of different modules. Please refer to the corresponding

description of individual modules or to their block diagrams.

CAUTION: The maximum current handling capacity of RJ-45 connections and flat-wire cables has to be

observed under all circumstances!

3. DCS 401 Addresses

➨ Using the Dip switch S1, the addresses of all connected control modules DCS 401 have to be set to different

numbers (addresses 0 - 7).

Dip switch S1 Address

1 2 3 4 5 6

OFF OFF OFF OFF OFF OFF 0

ON OFF OFF OFF OFF OFF 1

OFF ON OFF OFF OFF OFF 2

ON ON OFF OFF OFF OFF 3

OFF OFF ON OFF OFF OFF 4

ON OFF ON OFF OFF OFF 5

OFF ON ON OFF OFF OFF 6

ON ON ON OFF OFF OFF 7

4. Before initial operation

➨ Connect a 24V source. Now, each DCS 401 control module verifies whether any local modules (DCS 408, DCS

409, DCS 412, DCS 416) are connected, and if so, how many. The red LED blinks when the initialization process has not been performed yet.

➨ Only for DCS 401 control modules with software version previous to V1.1: Each

DCS 401 control module is initialized by pressing the S2 button for approximately 3 seconds. Afterwards, the red LED has to light continuously signaling that initialization was successfully completed.

➨ Launch netscan (menu communication / netscan within the PROANNOUNCE Designer software). Now, the DCS

401 modules are being initialized. Afterwards, the DPM 4000 runs a test verifying all addresses and recognizes the amount of DCS 401 control modules installed in the system. All components sharing the network are listed in the component list. This procedure takes approximately 20 seconds. Afterwards, the system is ready for operation.

6.2 DMM 4650 Interconnection

Interconnecting the DMM 4650 is established through control inputs and outputs on the DPM 4000 or on the DCS 400 monitoring system (DCS 408, DCS 409, DCS 412).

Every single sequence needs a control output for the start / stop command and a control input for the transmission of the return signal. The control output starts the DMM 4650 sequence with a positive slope and stops it with a negative slope. The return signal's control input reacts to the negative slope and activates the macro "Message Stop". Additionally, in most cases a control input is needed for the DMM 4650 READY / FAULT signal. The following cabling example offers a possibility for controlling three different sequences including fault recognition. This is accomplished by utilizing Port A on the DMM 4650 and the 8 I/O control module (IN 5 - 8 and OUT 5 - 8) of the DPM 4000.

Using an adapter cable (2 x RJ-45 to 25-pole D-Sub), the shown cabling is established with relative little effort.

For a larger amount of sequences, it is necessary to additionally utilize Ports B, C, and D on the DMM 4650. Triggering the sequence start / stop is accomplished through additional control outputs on the DPM 4000 control module (OUT 2 -

4) or via relay contacts on the DCS 408 respectively on the DCS 409 modules. The return signal is present at the

control inputs IN 1 - 4 of the DPM 4000 control module; additional control inputs can be provided via DCS 412 modules.

For controlling a DMM 4650 sequence, first you have to assign the start / stop and return message lines in the PROANNOUNCE Designer software. Afterwards, defining the audio signals in the window “External Audio Signals DMM 4650” is possible (the window opens when double-clicking onto the DMM 4650 symbol), where start / stop and return message lines are assigned to individual audio signals. When this is done, starting a DMM 4650 sequence from a paging console is already possible. Individual zones are assigned in the paging console dialog (key-assignment).

Defining additional triggers and zones is possible for the case that different events than a paging station keystroke (external triggers, timer) are used to start a DMM 4650 sequence. Displaying text on the LCD during the output of a DMM 4650 sequence is possible as well.

Programming examples for interconnecting the DMM 4650 are provided in the file Demo99_2.pmx, which is installed during the installation of the PROANNOUNCE Designer software within the following directory: /proannounce/examples/.
