SYSTEM DESCRIPTION

3.9Macros

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.

3.10Interfaces

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.

3.11Safety 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.
