The PVA-2P500 class-D amplifier is a 2 ✕ 500 W professional audio amplifier for evacuation purposes. It can be operated from both the mains and a DC supply. The output voltage is galvanically insulated and is constantly monitored for a ground fault. An energy- saving mode and temperature-controlled fans reduce energy consumption and noise levels. The control and monitoring functions are performed via CAN bus. This amplifier is designed for operation in an emergency evacuation system. The amplifiers are usually controlled via a controller and configured using IRIS-Net.

The PVA-15CST is a call station for the PAVIRO system. As standard, the call station has a gooseneck microphone with pop shield and permanent monitoring, a total of 20 buttons, an illuminated LC display, and an integrated loudspeaker. The call station can be modified to suit the user’s requirements by connecting up to five PVA-20CSE call station extensions, each with 20 customizable selection buttons.
Five menu/function keys (pre-programmed) – one green or one yellow indicator light per button
15 selection buttons (customizable) – two indicator lights (green/red) per button
Label with transparent covering – the label can be changed at any time
Can be used as a standing or desk/rack flush- mounted device
Internal monitoring with error logging – complying with all relevant national and international standards
Easy configuration – use of the Configuration Wizard or IRIS-Net software
The PVA-4R24 24 Zone Router is a zone extension for the PAVIRO system. The PVA-4R24 adds 24 zones, 20 GPIs, 24 GPOs and 2 control relays to the system and is controlled and supervised via the CAN bus by the PVA-4CR12 (Controller). Up to 20 external routers can be connected to one controller. One router can handle up to 4000 W speaker load. The maximum load of one zone is 500 W.
The zone indicator lights on the front indicate the current status of every zone:
