Descriptions:
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.
Basic Functions
* 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).
