IDA4M(s) - IDA4XM(s)
Stackable PAVA System - EN 60849
IDA4M / IDA4XM / Master unit
IDA4Ms / IDA4XMs / Slave unit
IDA4M /XM Product range responds to Public Address requirements and EN 60849 compliance for medium and large scale installations. It comprises the cascading of an IDA4M Master unit and one or several IDA4Ms/XMs Slave units. This module assembly extends the system’s capacity to 288 inputs x 256 outputs.
Each module unit houses: Audio digital signal processing (DSP), a matrix, a digital message player, amplifiers monitoring with switchover to backup amplifier, and loudspeaker lines monitoring.
Each module can support 1 PSSDT security microphone console or up to 16 cascaded PSM8 microphone consoles and can process and route another four 0 dB audio inputs into 4 different zones. Each channel is fitted with volume controls, equalizers, and a programmable delay. Each 0 dB input features contact and VOX activation which is ideal when using the cordless microphone for example.
Up to 12 digital messages can be downloaded and recorded as WAV files directly from a computer into IDA4M/XM and IDA4Ms/XMs.
Four messages can be played simultaneously in different zones. A security message is pre-programmed in 4 languages.
One of the messages can be used as a chime for the PSS/PSM8 microphone.
4 alarm inputs making it possible to obtain the pre programmed routings. The 4 output contacts can be used to disable the 100 V line attenuators.
As an EN60849 security system, all IDA4 System components and peripherals are monitored. All incidents are recorded into a data file which can be consulted on the master module monitor display or on a PC. Also any detected faults are signaled by a general fault output contact. A local loudspeaker output enables selective listening to all the sources and the system’s 100 V output signals. The setup of IDA4 System is realized through a PC computer and the configuration software. (Windows compatible). Access can be password protected. The routing and the level of the music sources can be controlled directly from the PSS/PSM8 microphones.
Furthermore, IDA4M/XM and IDA4Ms/XMs can be combined with the IDA4SU when fault back microphone and a+b wiring features are requested. Several IDA4 System racks can be remotely controlled from a remote location.
A MODBUS protocol allows third party system to control IDA4M/XM over a serial link.
