VOICE ALARM SYSTEM
Product in Summary
EVS8820 is an extension amplifier for EVM8810. Combining both the controller and extension unit provides larger setup of 16 zones and
above with amplifier capacity of exceeding 2000W 100V line.
It consists of 8 zone speaker line outputs and can conveniently connect to EVM8810 via simple connecting RJ45 cable. EVS8820 is also an
1000W 100V power pack with built in Auto Fault Sensing circuit ( AFS ).
In essense, Amperes EVM8820 + EVS8810 represent more than just an Integrated Voice Alarm Controller system; it symbolizes an innovative
transformation of conventional PA setup to a more compact and versatile system, both for Paging, BGM and EVAC broadcast.
