ITC VA-6000MS

Digital Professional electronical Voice alarm switching

Our Fire Alarm Systems for PA and evacuation systems in accordance with EN 54-16 combine unique functionality in perfection with extremely simple programming and operation.

The optimum customer penefit results from state-of-the-art technologies and many years of experience, put into practice consistently.

Product Description

VA-6000MS changeover is an integrated controller supporting main and backup amp swithing, speaker circuit grounding detection, open circuit and short circuit detection; compatible with three or four wire volume controller wiring, without extra wiring or power supply; combining 8 programmable stem node or wet node trigger inputs and 8 programmable on-line output signal. It works with class D amplifiers, traditional amplifiers to provid a safe, affordable solution to the PA & Voice Alarm system.

Features

*2U chassis design, high integrated, modularization;

*support speaker circuit grounding, open circuit and short circuit detection;

*support 3/4 wire horn circuit wiring;

*8 programmable trigger input interfaces;

*8 programmable trigger output interfaces;

*support power-saving mode when the amplifier has not input signal enters

*support lines redundance wiring;

*support linkage to fire alarm controller

Funtion:

*main amplifier automatic backup switching power amplifier, real-time detection, indicate by different color LEDs;

*real time monitoring speaker bus loop, power amplifier status, automatic control switch;

*allows amplifier enter into power saving mode when no signal input to save energy (start through VA-6000ST, default disabled);

*allows to configure the priority of network and local audio;

*support power through, even if the main and standby power supply is cut off at the same time (amplifier power supply normal), the local 8 audio signals are not affected;

*8 stem node or wet node input port, to trigger the pre-pragrammed language information to the specified zones or open the coresposing external power to the corresponding event warning;

*8 programmable relay signal output port, ouupt no voltage output short circuit relay control signal to the third party equipment to realize on-line automatic control;

*provide DC 24V standby power input interface ( connect to 24V DC supplied by VA-6000BC);
