MAIN EMERGENCY FEATURES
• Frontal Fireman’s microphone. It works only under Emergency
Manual and has priority over pre recorded messages of an
emergency. The microphone capsule is controlled by the internal
diagnostic system
• Emergency button with LED (red) collected for the activation
of the Emergency Manual mode. Allows access to the system,
with absolute priority, from the “State of Quiet” or during the
Emergency Automatic ongoing, previously activated by external
devices
• Remote emergency microphones units, PMB132 series
• Control and monitoring of the integrity of the critical path (from the
emergency signal sources to the loudspeaker lines)
• Continuous loudspeaker line monitoring (integrity and dispersion
to earth) without interruption of BGM or paging calls
• Two output loudspeaker lines for each zone (A & B)
• Built-in message generator to broadcast prerecorded messages
(EVAC and ALERT)
• Back-up power amplifier management (built-in unit)
• Complete diagnostic of system fault events
• Management of a secondary source of 24 Vdc power with a
battery-charging unit

• External 250 W amplifier to increase power (AW5624)
• Up to 7 remote emergency microphone units (SFTP CAT5 cable)
• Up to 16 paging units, 7 priority levels (SFTP CAT5 cable)
• Balanced microphone input (IN 1) with Phantom power supply and
priority contact
• Balanced microphone or line input (IN 2) with Phantom power
supply (MIC), priority contact or automatic precedence (VOX)
• Balanced line input (IN 3) with automatic precedence (VOX)
• Auxiliary line input for an external music source
• USB input for background music source
• 6 open collector outputs (system status or override to by pass
attenuators)
• 8 programmable and controlled input contacts
• 2 relay outputs for emergency and failure conditions
• Built-in loudspeaker for channel monitoring and acoustic failure
signalling (beep)
• Graphic display 128x64 pixel monochrome, for displaying multiple
windows management
• Multi-function keys and knob help to navigate through the menus
• Emergency zone disabling and Do Not Disturb functions (DND)

To PA8506-V can
be easily and quickly
connected up to 16
microphone paging
units (PMB106-G and
PMB112-G) and up to 7
microphone emergency
units PMB132-V and
PMB132/12-V), which
allow to send messages
either to one or more
zones. The usage of
shielded cables CAT5e
