Observe the guidelines with respect to handling MOS components. Risk of explosion if battery is not replaced correctly. Must be replaced only with the same or equivalent type of battery. The system can be adjusted to requirements via the eight slots for audio input, audio output or message manager modules.
A single DPM can manage up to 16 call stations and up to loudspeaker circuits; in larger systems, up to ten DPM controllers can be linked with each other via a digital audio and control bus.
The following block diagram shows a PROMATRIX system with DPM central unit, call stations, audio equipment, amplifiers, a power supply, relay cards and loudspeaker circuits, as well as control cards for external signals. The system can be adjusted to system requirements via the 8 slots for audio input, audio output or message manager modules.
The type and number of connected audio sources, amplifiers, and relay cards are extremely variable, and can be adjusted to individual requirements. A single DPM can manage up to 16 call stations and up to zones; in larger systems, up to 10 DPM controllers can be linked with each other via a digital audio and control bus. Control inputs and outputs can be Dec 02 F01U Operation manual System description en DPM 9 used for controlling and monitoring functions, and allow both the logic level and the analog level to be processed and generated.
Configuration is performed on a PC using the IRIS-Net software, which also provides access to system documentation and the required user interface. A configuration can be changed at any time, and adjusted to new circumstances without having to modify the system installation. A PC is required only for loading or changing the configuration; it does not need to be connected during live operation.
In many cases, however, a permanently connected PC is helpful; for example, to provide detailed status displays and log reports, real-time loudspeaker and sound control, or for remote diagnosis and maintenance via the network. The user interface can be individually tailored, and up to 32 password levels can be assigned.
Audio routing A digital 36 x 16 audio matrix is integrated into the DPM Up to 16 local audio inputs, 4 internal generators, and 16 optional CobraNet network inputs are available. The 16 matrix outputs can be used as local audio outputs, or optionally provided via the CobraNet network. This means 16 audio channels can be used in parallel, and connected to the amplifiers. Each loudspeaker circuit can be connected with amplifier outputs via a relay matrix, which allows for loudspeaker zones.
The DPM manages the audio signals, and distributes them according to priority. In addition to the call stations, other audio sources can also be connected to the audio inputs such as microphones, mixing desks, CD players, MP3 players, tuners, and so on. A number of different connections are available for optimum adjustment. Audio processing The DPM provides separate volume controls with a mute function for each audio input and audio output.
Each audio input has a 3-band equalizer and a compressor for optimal sound adjustment of the audio sources. All outputs are fitted with a 5-band equalizer and a limiter.
For the equalizers, the operator can select from six different filter types for each band filter peak, low-shelving, high-shelving, high pass, low pass, all pass.
Volume levels, filter parameters, and so on are set on the PC during configuration. However, these can also be changed in real-time during operation using the graphical user interface, the special keys for the call stations, or external operating controls.
Signal generators The DPM provides four signal generators: Two independent generators for generating alarm signals and two independent generators for generating gong signals. Operators can choose between 24 alarm types and six gong types that are available ex-works. However, special commands such as volume control, monitor selection, preset switching, light control, function displays, and much more are also possible.
The call stations can therefore also be configured for general control tasks. If an announcement is to be routed through a loudspeaker circuit that is already occupied, the system issues an occupied notification i. The system naturally includes safeguards relating to this: The user is notified that the system is occupied when selecting the circuit before the interruption by the flashing BUSY-LED.
The user can now decide whether to interrupt the signal immediately, or whether to wait until the end of the active announcement. System information or error messages can be displayed on the call station's illuminated graphic display. The control inputs allow a connection to be established to fire alarm systems, intruder alarm systems, or a control desk. However, it is also possible to connect external switches, controllers, or rotary encoders, or to retrieve output messages from external equipment power supply, power amplifiers, and so on.
The system clock automatically recognizes leap years; in DCF77 mode, it also automatically switches to daylightsaving time. Up to 40 external slave clocks can be controlled by the system clock. A special output for polarity switch impulses, which is protected against short circuits, is integrated in the DPM for this purpose.
Slave clocks are automatically adjusted if a time difference between the slave clocks and the system clock is detected, for example after a power failure or in the event of manual input. Together with the calendar function, the system clock can be used to execute functions such as a break gong, music, gate control, light control, and so on. These functions can be programmed for specific days, but can also be implemented on an hourly, daily, weekly, monthly, and annual basis. Up to time-controlled events can be entered.
Functions and parameters can be connected in an internal sequence. The TaskEngine in the DPM provides a graphic display that allows the user to combine processes individually. One example would be a gong signal to be transmitted at a certain volume and with a specific priority in specific call groups, and which simultaneously activates a control output. The processes can be triggered via special function keys on the call stations or via control inputs, but can also be linked to clock or calendar dates.
Up to four call stations can be connected via one PCA bus. The connection to a PC is established via an Ethernet interface. The Ethernet interface is used to connect several DPM controllers. The redundant, optional CobraNet interface is used to transmit audio data. Security features The DPM monitors all internal functions itself, and the connected call stations and power amplifiers including their connection lines are also monitored by polling and pilot tone. The PROMATRIX system also supports emergency power operation — in the event of a power failure, the DPM can assume all power management functions, that is, all unnecessary internal and external consumers switch to standby mode, or are deactivated and only reactivated again when required.
This greatly Dec 02 F01U Operation manual System description en DPM 11 reduces power consumption, and ensures maximum operating time on battery power. Error messages can be displayed on the call station displays in plain text. A potential-free contact is used on the DPM for batch messages. Operating Instructions In accordance with the specified and technical details for this product, the DPM can be used to control and monitor public address and call systems within the building installation, as well as for professional audio systems.
