EVS8820 Front
new product

EVS8820 works alongside EVM8810 which acts as the central control unit for the system. It is essentially an extension or additional unit that helps in expanding the coverage area of the voice alarm system. Using EVM8810 alone can connect with 8 speakers and with this extension, it can connect up to 16 speakers. 

It comes with high efficiency Class D amplifier and a built-in monitoring speaker with volume control. EVS8820 also provides programmable ALL Call relay trigger or front button ALL Call for remote paging. It has a Auto Fault Sensor (AFS) and it can self diagnose for faulty unit. Whenever EVM8820 doesn't detect any incoming signal, it will reduce power consumption by having a switchable standby power.
